Sake,saké(Rượu,sake,/ˈsɑːki,ˈsækeɪ/SAH-kee,SAK-ay),orsaki,also referred to as Japaneserice wine,is an alcoholic beverage ofJapaneseorigin made by fermentingricethat has beenpolishedto remove thebran.Despite the nameJapanese rice wine,sake, and indeed any East Asian rice wine (such ashuangjiuandcheongju), is produced by abrewingprocess more akin to that ofbeer,wherestarchis converted into sugars that ferment into alcohol, whereas inwine,alcoholis produced byfermentingsugar that is naturally present in fruit, typically grapes.

The brewing process for sake differs from the process for beer, where the conversion from starch to sugar and then from sugar to alcohol occurs in two distinct steps. Like otherrice wines,when sake is brewed, these conversions occur simultaneously. The alcohol content differs between sake, wine, and beer; while most beer contains 3–9%ABV,wine generally contains 9–16%ABV,and undiluted sake contains 18–20%ABV(although this is often lowered to about 15% by diluting with water before bottling).

InJapanese,the charactersake(kanji:Rượu,Japanese pronunciation:[sake]) can refer to anyalcoholic drink,while the beverage called sake in English is usually termednihonshu(Nhật Bản rượu;meaning 'Japanese alcoholic drink'). Under Japaneseliquor laws,sake is labeled with the wordseishu(Rượu gạo;'refined alcohol'), a synonym not commonly used in conversation.

In Japan, where it is the national beverage, sake is often served with specialceremony,where it is gently warmed in a small earthenware orporcelainbottle and sipped from a small porcelain cup called asakazuki.As with wine, the recommended serving temperature of sake varies greatly by type.

Sake now enjoys an international reputation. Of the more than 800junmai ginjō-shuevaluated byRobert Parker's team, 78 received a score of 90 or more (eRobertParker,2016).

History

Until the Kamakura period

The origin of sake is unclear; however, the method of fermenting rice into alcohol spread to Japan from China around 500BCE.The earliest reference to the use of alcohol in Japan is recorded in theBook of Weiin theRecords of the Three Kingdoms.This 3rd-century Chinese text speaks of Japanese drinking and dancing.

Alcoholic beverages(Rượu,sake)are mentioned several times in theKojiki,Japan's first written history, which was compiled in 712. Bamforth (2005) places the probable origin of true sake (which is made from rice, water, andKoji(Khúc,Aspergillus oryzae)) in theNara period(710–794).The fermented food fungi traditionally used for making alcoholic beverages in China and Korea for a long time were fungi belonging toRhizopusandMucor,whereas in Japan, except in the early days, the fermented food fungus used for sake brewing wasAspergillus oryzae.Some scholars believe the Japanese domesticated the mutated, detoxifiedAspergillus flavusto give rise toAspergillus oryzae.

In theHeian period(794–1185), sake was used for religious ceremonies, court festivals, and drinking games.Sake production was a government monopoly for a long time, but in the 10th century,Buddhist templesandShinto shrinesbegan to brew sake, and they became the main centers of production for the next 500 years.

Muromachi period

Before the 1440s in theMuromachi period(1333－1573), the Buddhist templeShōryaku-jiinvented various innovative methods for making sake. Because these production methods are the origin of the basic production methods for sake brewing today, Shoryakuji is often said to be the birthplace ofseishu(Rượu gạo). Until then, most sake had beennigorizakewith a different process from today's, but after that, clearseishuwas established. The main production methods established by Shōryaku-ji are the use of all polished rice (morohaku zukuri,Chư bạch tạo り), three-stage fermentation (sandan zikomi,Tam đoạn sĩ 込み), brewing of starter mash using acidic water produced by lactic acid fermentation (bodaimoto zukuri,Bồ đề 酛づくり), andpasteurization(hiire,Hỏa nhập れ). This method of producing starter mash is calledbodaimoto,which is the origin ofkimoto.These innovations made it possible to produce sake with more stable quality than before, even in temperate regions. These things are described inGoshu no nikki(ja: Ngự rượu ngày nhớ), the oldest known technical book on sake brewing written in 1355 or 1489, andTamonin nikki(ja: Nhiều môn viện nhật ký), a diary written between 1478 and 1618 by monks ofKōfuku-jiTemple in the Muromachi period.

A huge tub (ja: Thùng) with a capacity of 10koku(1,800 liters) was invented at the end of the Muromachi period, making it possible to mass-produce sake more efficiently than before. Until then, sake had been made in jars with a capacity of 1, 2, or 3kokuat the most, and some sake brewers used to make sake by arranging 100 jars.

In the 16th century, the technique of distillation was introduced into the Kyushu district from Ryukyu.The brewing ofshōchū,called "Imo–sake" started and was sold at the central market inKyoto.

Edo period

By theGenrokuera (1688–1704) of theEdo period(1603–1867), a brewing method calledhashira jōchū(Trụ thiêu trữu) was developed in which a small amount of distilled alcohol (shōchū) was added to the mash to make it more aromatic and lighter in taste, while at the same preventing deterioration in quality. This originates from the distilled alcohol addition used in modern sake brewing.

TheNada-Gogōarea inHyōgo Prefecture,the largest producer of modern sake, was formed during this period. When the population ofEdo,modern-dayTokyo,began to grow rapidly in the early 1600s, brewers who made sake in inland areas such asFushimi,Itami,andIkedamoved to the Nada-Gogō area on the coast, where the weather and water quality were perfect for brewing sake and convenient for shipping it to Edo. In the Genroku era, when the culture of thechōninclass, the common people, prospered, the consumption of sake increased rapidly, and large quantities oftaruzake( tôn rượu ) were shipped to Edo. 80% of the sake drunk in Edo during this period was from Nada-Gogō. Many of today's major sake producers, including Hakutsuru (ja: Bạch hạc), Ōzeki (ja: Đại quan), Nihonsakari (ja: Nhật Bản thịnh), Kikumasamune (ja: Cúc chính tông), Kenbishi (ja: Kiếm lăng) andSawanotsuru,are breweries in Nada-Gogō.

During this period, frequent natural disasters and bad weather caused rice shortages, and theTokugawa shogunateissued sake brewing restrictions 61 times.In the early Edo period, there was a sake brewing technique calledshiki jōzō(Bốn mùa 醸 tạo) that was optimized for each season. In 1667, the technique ofkanzukuri(Hàn tạo り) for making sake in winter was improved, and in 1673, when the Tokugawa shogunate banned brewing other thankanzukuribecause of a shortage of rice, the technique of sake brewing in the four seasons ceased, and it became common to make sake only in winter until industrial technology began to develop in the 20th century.During this period, aged for three, five, or nine years,koshu(Cổ rượu) was a luxury, but its deliciousness was known to the common people.

Title page ofBereiding van Sacki,byIsaac Titsingh:earliest explanation of the sake brewing process in a European language. Published in 1781, inBatavia, Dutch East Indies.

In the 18th century,Engelbert KaempferandIsaac Titsinghpublished accounts identifying sake as a popular alcoholic beverage in Japan, but Titsingh was the first to try to explain and describe the process of sake brewing. The work of both writers was widely disseminated throughout Europe at the beginning of the 19th century.

From the Meiji era to the early Shōwa era

Starting around the beginning of theMeiji era(1868－1912), the technique for making sake began to develop rapidly. Breeding was actively carried out in various parts of Japan to producesake riceoptimized for sake brewing.Ise Nishikideveloped in 1860,Omachi(ja: Hùng đinh) developed in 1866 andShinrikideveloped in 1877 are the earliest representative varieties. In 1923,Yamada Nishiki,later called the "king of sake rice," was produced.Among more than 123 varieties of sake rice as of 2019, Yamada Nishiki ranks first in production andOmachifourth.The government opened the sake-brewing research institute in 1904, and in 1907 the first government-run sake-tasting competition was held. In 1904, the National Brewing Laboratory developedyamahai,a new method of making starter mash, and in 1910, a further improvement,sokujō,was developed.Yeaststrains specifically selected for their brewing properties were isolated, and enamel-coated steel tanks arrived. The government started hailing the use of enamel tanks as easy to clean, lasting forever, and devoid of bacterial problems. (The government considered wooden tubs (ja: Thùng) to be unhygienic because of the potential bacteria living in the wood.) Although these things are true, the government also wanted more tax money from breweries, as using wooden tubs means a significant amount of sake is lost to evaporation (approximately 3%), which could have otherwise been taxed. This was the temporary end of the wooden-tubs age of sake, and the use of wooden tubs in brewing was temporarily eliminated.

In Japan, sake has long been taxed by the national government. In 1878, the liquor tax accounted for 12.3% of the national tax revenue, excluding local taxes, and in 1888 it was 26.4%, and in 1899 it was 38.8%, finally surpassing the land tax of 35.6%.In 1899, the government banned home brewing in anticipation of financial pressure from theFirst Sino-Japanese Warand in preparation for theRusso-Japanese War.Since home-brewed sake is tax-free, the logic was that by banning the home-brewing of sake, sales would increase, and more tax revenue would be collected. This was the end of home-brewed sake.The Meiji government adopted a system in which taxes were collected when sake was finished, instead of levying taxes on the amount and price of sake at the time of sale to ensure more revenue from liquor taxes. The liquor tax for the sake produced in a given year had to be paid to the government during that fiscal year, so the breweries tried to make money by selling the sake as soon as possible. This destroyed the market for agedkoshu,which had been popular until then, and it was only in 1955 that sake breweries began to makekoshuagain.

WhenWorld War IIbrought rice shortages, the sake-brewing industry was hampered as the government discouraged the use of rice for brewing. As early as the late 17th century, it had been discovered that small amounts of distilled alcohol could be added to sake before pressing to extract aromas and flavors from the rice solids. During the war, large amounts of distilled alcohol andglucosewere added to small quantities of rice mash, increasing the yield by as much as four times. A few breweries were producing "sake" that contained no rice. The quality of sake during this time varied considerably. Incidentally, as of 2022, so much distilled alcohol is not allowed to be added, and under the provisions of the Liquor Tax Act, 50% of the weight of rice is the upper limit for the most inexpensive sake classified asfutsū-shu.

Since the mid-Showa era

After the war, the breweries gradually recovered and the quality of sake steadily improved, and there were various innovations in sake brewing. The termginzō(Ngâm tạo), which means carefully brewed sake, first appeared at the end of the Edo period, and the termginjō(Ngâm 醸), which has the same meaning, first appeared in 1894. However,ginjō-shu(Ngâm 醸 rượu), which is popular in the world today, was created by the development of various sake production techniques from the 1930s to around 1975. From 1930 to 1931, a new type of rice milling machine was invented, which made it possible to make rice with a polishing ratio of about 50%, removing the miscellaneous taste derived from the surface part of the rice grain to make sake with a more aromatic and refreshing taste than before. In 1936,Yamada Nishiki,the most suitable sake rice for brewingginjō-shu,became the recommended variety ofHyogo Prefecture.Around 1953, the "Kyokai yeast No. 9" (kyokai kyu-gō kōbo,Hiệp hội 9 hào con men) was invented, which produced fruit-like aromas like apples and bananas but also excelled in fermentation. From around 1965, more and more manufacturers began to work on the research and development ofginjō-shu,and by about 1968, the Kyokai yeast No. 9 began to be used throughout Japan. In the 1970s, temperature control technology in the mash production process improved dramatically. And by slowly fermenting rice at low temperatures using high-milled rice and a newly developed yeast,ginjō-shuwith a fruity flavor was created. At that time,ginjō-shuwas a special sake exhibited at competitive exhibitions and was not on the market. From around 1975,ginjō-shubegan to be marketed and was widely distributed in the 1980s, and in 1990, with the definition of what can be labeled asginjō-shu,more and more brewers began to sellginjō-shu.The growing popularity ofginjō-shuhas prompted research into yeast, and many yeasts with various aromas optimized forginjō-shuhave been developed.

In 1973, theNational Tax Agency's brewing research institute developedkijōshu(Quý 醸 rượu).

New players on the scene—beer, wine, and spirits—became popular in Japan, and in the 1960s, beer consumption surpassed sake for the first time. Sake consumption continued to decrease while the quality of sake steadily improved. While the rest of the world may be drinking more sake and the quality of sake has been increasing, sake production in Japan has been declining since the mid-1970s.The number of sake breweries is also declining. While there were 3,229 breweries nationwide in fiscal 1975, the number had fallen to 1,845 in 2007.In recent years, exports have rapidly increased due to the growing popularity of sake worldwide. The value of sake exports in 2022 was more than six times that of 2009.As of 2022, the value of Japan's alcoholic beverage exports was approximately 139.2 billion yen, withJapanese whiskyin first place at 56.1 billion yen and sake in second place at 47.5 billion yen.Today, sake has become a world beverage with a few breweries in China, Southeast Asia, South America, North America, and Australia.

In addition toAspergillus oryzae(yellowkōji),Aspergillus kawachii(whitekōji) andAspergillus luchuensis(blackkōji), which are used to brewshōchūandawamori,have been used to brew sake since the 21st century.

More breweries are also turning to older methods of production. For example, since the 21st century, the use of wooden tubs has increased again due to the development of sanitary techniques. The use of wooden tubs for fermentation has the advantage of allowing variousmicroorganismsliving in the wood to affect sake, allowing more complex fermentation and producing sake with different characteristics. It is also known that the antioxidants contained in wood have a positive effect on sake.

Oldest sake brewery

The oldest sake brewing company still in operation, as confirmed by historical documents, is theSudo HonkeinKasama, Ibaraki,founded in 1141 during theHeian Period(794–1185).Sudō Honkewas also the first sake brewery to sell bothnamazakeandhiyaoroshi.Hiyaoroshirefers to sake that is finished in winter, pasteurized once in early spring, stored and aged for a little while during the summer, and shipped in the fall without being pasteurized a second time.

In terms of excavated archaeological evidence, the oldest known sake brewery is from the 15th century near an area that was owned byTenryū-ji,inUkyō-ku, Kyoto.Unrefined sake was squeezed out at the brewery, and there are about 180 holes (60 cm wide, 20 cm deep) for holding storage jars. A hollow (1.8 meter wide, 1 meter deep) for a pot to collect drops of pressed sake and 14th-centuryBizen warejars were also found. It is estimated to be utilized until theOnin War(1467–1477). Sake was brewed atTenryū-jiduring theMuromachi Period(1336–1573).

Rice

The rice used for brewing sake is calledsakamaiRượu mễ(さかまい) ('sake rice'), or officiallyshuzō kōtekimaiRượu tạo hảo thích mễ(しゅぞうこうてきまい) ('sake-brewing suitable rice').There are at least 123 types of sake rice in Japan.Among these,Yamada Nishiki,Gohyakumangoku (ja: 500 vạn thạch), Miyama Nishiki (ja: Mỹ sơn cẩm) and Omachi (ja: Hùng đinh) rice are popular.The grain is larger, stronger (if a grain is small or weak, it will break in the process of polishing), and contains less protein and lipid than ordinary table rice. Because of the cost, ordinary table rice, which is cheaper than sake rice, is sometimes used for sake brewing, but because sake rice has been improved and optimized for sake brewing, few people eat it.

Premium sake is mostly made from sake rice. However, non-premium sake is mostly made from table rice. According to the Japan Sake and Shochu Makers Association, premium sake makes up 25% of total sake production, and non-premium sake (futsushu) makes up 75% of sake production. In 2008, a total of 180,000 tons of polished rice were used in sake brewing, of which sake rice accounted for 44,000 tons (24%), and table rice accounted for 136,000 tons (76%).

Sake rice is usually polished to a much higher degree than ordinary table rice. The reason for polishing is a result of the composition and structure of the rice grain itself. The core of the rice grain is rich in starch, while the outer layers of the grain contain higher concentrations of fats, vitamins, and proteins. Since a higher concentration of fat and protein in the sake would lead to off-flavors and contribute rough elements to the sake, the outer layers of the sake rice grain is milled away in a polishing process, leaving only the starchy part of the grain (some sake brewers remove over 60% of the rice grain in the polishing process). That desirable pocket of starch in the center of the grain is called theshinpaku(Tâm bạch,しんぱく). It usually takes two to three days to polish rice down to less than half its original size. The rice powder by-product of polishing is often used for makingrice crackers,Japanese sweets (i.e.Dango), and other food stuffs.

If the sake is made with rice with a higher percentage of its husk and the outer portion of the core milled off, then more rice will be required to make that particular sake, which will take longer to produce. Thus, sake made with rice that has been highly milled is usually more expensive than sake that has been made with less-polished rice. This does not always mean that sake made with highly milled rice is of better quality than sake made with rice milled less. Sake made with highly milled rice has a strong aroma and a light taste without miscellaneous taste. It maximizes the fruity flavor ofginjō.On the other hand, sake made with less milled rice but with attention to various factors tends to have a rich sweetness and flavor derived from rice.

Rice polishing ratio,calledSeimai-buaiTinh mễ bộ hợp(せいまいぶあい) (seeGlossary of sake terms) measures the degree of rice polishing. For example, a rice polishing ratio of 70% means that 70% of the original rice grain remains and 30% has been polished away.As of 2023, the most polished sake will have a polishing ratio of 0.85% or less, with at least 99.15% of its rice grains polished away. This sake will beReikyo Crystal 0(Linh vang Crystal 0),released by Niizawa Brewery Co. ( tân trạch 醸 tạo cửa hàng ), priced at 1,375,000 yen for 720 ml.

Water

Water is involved in almost every major sake brewing process, from washing the rice to diluting the final product before bottling. The mineral content of the water can be important in the final product.Ironwill bond with anamino acidproduced by thekōjito produce off flavors and a yellowish color.Manganese,when exposed to ultraviolet light, will also contribute to discoloration. Conversely,potassium,magnesium,andphosphoric acidserve as nutrients for yeast during fermentation and are considered desirable.The yeast will use those nutrients to work faster and multiply resulting in more sugar being converted into alcohol. While soft water will typically yield sweeter sake, hard water with a higher mineral content is known for producingdrier-stylesake.

The first region known for having great water was theNada-GogōinHyōgo Prefecture.A particular water source calledMiyamizuwas found to produce high-quality sake and attracted many producers to the region. Today Hyōgo has the most sake brewers of any prefecture.

Typically breweries obtain water from wells, though surface water can be used. Breweries may use tap water and filter and adjust components.

Kōji-kin

Aspergillus oryzae(yellowkōji)

Aspergillus oryzaespores are another important component of sake.A. oryzaeis an enzyme-secretingfungus.In Japan,A. oryzaeis used to make various fermented foods, includingmiso(a paste made from soybeans) andshoyu(soy sauce).It is also used to make alcoholic beverages, notably sake.During sake brewing, spores ofA. oryzaeare scattered over steamedriceto producekōji(rice in whichA. oryzaespores are cultivated).Under warm and moist conditions, theA. oryzaespores germinate and releaseamylases(enzymes that convert the ricestarchesinto maltose and glucose). This conversion of starch into simple sugars (e.g., glucose or maltose) is calledsaccharification.Yeast thenfermentthe glucose and other sugar intoalcohol.Saccharification also occurs inbeerbrewing, wheremashingis used to convert starches frombarleyinto maltose.However, whereas fermentation occursaftersaccharification in beer brewing, saccharification (viaA. oryzae) and fermentation (via yeast) occursimultaneouslyin sake brewing (see "Fermentation" below).

AsA. oryzaeis a microorganism used to manufacture food, its safety profile concerning humans and the environment in sake brewing and other food-making processes must be considered. Various health authorities, includingHealth Canadaand theU.S.Food and Drug Administration(FDA), considerA. oryzaegenerally safe for use in food fermentation, including sake brewing.When assessing its safety, it is important to note thatA.oryzaelacks the ability to produce toxins, unlike the closely relatedAspergillus flavus.To date, there have been several reported cases of animals (e.g.parrots,ahorse) being infected withA. oryzae.In these cases the animals infected withA. oryzaewere already weakened due to predisposing conditions such as recent injury, illness or stress, hence were susceptible to infections in general.Aside from these cases, there is no evidence to indicateA. oryzaeis a harmful pathogen to either plants or animals in the scientific literature.Therefore, Health Canada considersA. oryzae"unlikely to be a serious hazard tolivestockor to other organisms, "including" healthy or debilitated humans. "Given its safety record in the scientific literature and extensive history of safe use (spanning several hundred years) in the Japanese food industry, the FDA andWorld Health Organization(WHO) also support the safety ofA. oryzaefor use in the production of foods like sake.In the US, the FDA classifiesA.oryzaeas aGenerally Recognized as Safe(GRAS) organism.

Aspergillus kawachii(whitekōji)

In addition toAspergillus oryzae(yellowkōji),Aspergillus kawachii(whitekōji) andAspergillus luchuensis(blackkōji), which are used to brewshōchūandawamori,have been used to brew sake since the 21st century.

From the 1980s, research was conducted to brew sake usingAspergillus kawachii(whitekōji), which is used to makeshōchū,and sake made withAspergillus kawachiibecame popular when Aramasa Co, Ltd. released "Amaneko" usingAspergillus kawachiiin 2009.Aspergillus kawachiiproduces about 10 times morecitric acidthanAspergillus oryzae,and thus has a strong ability to suppress the growth of bacteria that damage the flavor of sake. It also imparts a sour, citrus-like flavor to sake. Because it produces so much citric acid, older sake-making methods such askimotooryamahaican produce a starter mash as quickly as modernsokujō.Kimotoandyamahaido not add artificial lactic acid, which allows them to be labeled "additive-free," giving them a marketing advantage when exporting.

Aspergillus luchuensis(blackkōji)

As of 2022, sake made withAspergillus luchuensis(blackkōji,) will not be as popular as sake made withAspergillus kawachii.It produces more citric acid thanAspergillus kawachii.However, it produces lessamino acids,which produce complex flavors such asumami,bitterness, and sweetness, and morepeptides,which produce bitterness, resulting in a bitter taste from the peptides and a strong sour taste from the citric acid, which is sometimes compared to strawberry orred wine.

Fermentation

Moromi(the main fermenting mash) undergoing fermentation

Sake fermentation is a three-step process calledsandan shikomi.The first step, calledhatsuzoe,involves steamed rice, water, andkōji-kinbeing added to the yeast starter calledshubo:a mixture of steamed rice, water,kōji,and yeast.This mixture becomes known as themoromi(the main mash during sake fermentation).The high yeast content of theshubopromotes the fermentation of themoromi.

On the second day, the mixture stands for a day to let the yeast multiply.

The second step (the third day of the process), callednakazoe,involves the addition of a second batch ofkōji,steamed rice, and water to the mixture.On the fourth day of the fermentation, the third step of the process, calledtomezoe,takes place.Here, the third and final batch of kōji, steamed rice, and water is added to the mixture, followed by up to ten days or so of additional fermentation to complete the three-step process.

The multiple parallel fermentation process of sake brewing, where starch is converted into glucose followed by immediate conversion into alcohol,is unique to it.This distinguishes sake from other brewed alcoholic beverages like beer because it occurs in a single vat, whereas with beer, for instance, starch-to-glucose conversion and glucose-to-alcohol conversion occur in separate vats.The breakdown of starch into glucose is caused by thekōji-kinfungus, while the conversion of glucose into alcohol is caused by yeast.Due to the yeast being available as soon as the glucose is produced, the conversion of glucose to alcohol is very efficient in sake brewing.This results in sake having a generally higher alcohol content than other types of beer or wine.

After the fermentation process is complete, the fermentedmoromiis pressed to remove the sakeleesand then pasteurized and filtered for color.The sake is then stored in bottles under cold conditions (see "Maturation" below).

The process of making sake can range from 60 to 90 days (2–3 months), while the fermentation alone can take two weeks.On the other hand,ginjō-shutakes about 30 days for fermentation alone.

Maturation

Like other brewed beverages, sake tends to benefit from a period of storage. Nine to twelve months are required for the sake to mature. Maturation is caused by physical and chemical factors such as oxygen supply, the broad application of external heat, nitrogen oxides, aldehydes, and amino acids, among other unknown factors.

Tōji

Tōji(Đỗ thị)is the job title of the sakebrewer.There are various theories about the origin of the word, but the most popular is that it is a corruption of the wordtōji(Đao tự),which was used for housewives and elderly women who supervisedmiko(shrine maidens). This is because sake brewing was the work of housewives at home andmikoatShinto shrines.It is a highly respected job in theJapanese society,withtōjibeing regarded likemusiciansorpainters.The title oftōjiwas historically passed from father to son. Today newtōjiare either veteran brewery workers or are trained at universities. While modern breweries with cooling tanks operate year-round, most old-fashioned sake breweries are seasonal, operating only in the cool winter months. During the summer and fall, mosttōjiwork elsewhere, commonly on farms, only periodically returning to the brewery to supervise storage conditions or bottling operations.

Varieties

Special-designation sake

There are two basic types of sake:Futsū-shu(Bình thường rượu,ordinary sake)andTokutei meishō-shu(Riêng tên rượu,special-designation sake).Futsū-shuis the equivalent oftable wineand accounts for 57% of sake production as of 2020.Tokutei meishō-shurefers to premium sake distinguished by the degree to which the rice has been polished and the added percentage of brewer's alcohol or the absence of such additives. There are eight varieties of special-designation sake.

Ginjō(Ngâm 醸) is sake made using a special method calledginjō-zukuri(Ngâm 醸 tạo り), in which rice is slowly fermented for about 30 days at a low temperature of 5 to 10 degreesCelsius(41 to 50 degreesFahrenheit).Sake made inginjō-zukuriis characterized by fruity flavors like apples, bananas, melons, grapes, peaches, pineapples, citrus, etc. In general, the flavor of sake tends to deteriorate when it is affected byultraviolet raysor high temperatures, especially for sake made inginjō-zukuriand unpasteurizednamazake.Therefore, it is recommended that sake with the nameginjōbe transported and stored in cold storage. It is also recommended to drink chilled to maximize its fruity flavor.

Junmai(Thuần mễ) is a term used for the sake that is made of pure rice wine without any additional distilled alcohol.Special-designation sake which is not labeledJunmaihas an appropriate amount of distilled alcohol added. The maximum amount of distilled alcohol added tofutsū-shuis 50% of the rice weight, mainly to increase the volume, while the maximum amount of distilled alcohol added to special-designation sake is 10% of the rice weight, to make the sake more aromatic and light in taste, and to prevent the growth of lactic acid bacteria, which deteriorate the flavor of the sake.It is often misunderstood that the added distilled alcohol is of poor quality, but that is not the case with the addition of distilled alcohol to special-designation sake. Specifically, 78.3% of the sake entered in theZenkoku shinshu kanpyōkai( cả nước tân rượu giam bình sẽ, National New Sake Appraisal), the largest sake contest, had distilled alcohol added, and 91.1% of the winning sake had it added.However, the most important aspect of the contest is the brewing technique, not whether it tastes good or not.

Sake made with highly milled rice has a strong aroma and a light taste without miscellaneous taste. It maximizes the fruity flavor ofginjō.On the other hand, sake made with less milled rice but with attention to various factors tends to have a rich sweetness and flavor derived from rice.

The certification requirements for special-designation sake must meet the conditions listed below, as well as the superior aroma and color specified by theNational Tax Agency.The listing below often has the highest price at the top:

Methods of preparing the starter mash

• Bodaimoto(Bồ đề 酛) is a method used byShōryaku-jiinNarato make starter mash during theMuromachi period(1336–1573). In recent years, some sake breweries have begun to revive this method based on documents from the Muromachi period.
• Kimoto(Sinh 酛) is the traditional orthodox method for preparing the starter mash, which includes the laborious process of using poles to mix it into a paste, known asyama-oroshi.This method was the standard for 300 years.
• Yamahai(Sơn 廃) is a simplified version of thekimotomethod, introduced in the early 1900s.Yamahaiskips the step of making a paste out of the starter mash. That step of thekimotomethod is known asyama-oroshi,and the full name foryamahaiisyama-oroshi haishi(Sơn tá 廃 ngăn), meaning 'discontinuation ofyama-oroshi.While theyamahaimethod was originally developed to speed production time compared to thekimotomethod, it is slower than the modern method and is now used only in specialty brews for the earthy flavors it produces.
• Sokujō(Tốc 醸), 'quick fermentation,' is the modern method of preparing the starter mash. Lactic acid, produced naturally in the two slower traditional methods, is added to the starter to inhibit unwanted bacteria.Sokujōsake tends to have a lighter flavor thankimotooryamahai.

Different handling after fermentation

The blue sake bottle displays "Yamada Nishiki"( sơn điền cẩm ) and"Junmai Daiginjo"( thuần mễ đại ngâm 醸) on the bottom label and"Bingakoi muroka nama genshu"( bình 囲 vô lự quá sinh nguyên rượu ) and" requiring refrigeration "( muốn lãnh tàng ) on the top label. The label on the pink sake bottle indicatesUsunigori muroka nama genshu.

Nigori,or unfiltered sake

The characteristics of sake listed below are generally described on the label attached to the sake bottle. For example, "Shiboritatemurokanamagenshu"(しぼりたて vô lự quá sinh nguyên rượu ) indicates that all the conditions ofshiboritate,muroka,namazakeandgenshubelow are satisfied.

• Namazake(Sinh rượu) is sake that has not beenpasteurized.It requires refrigerated storage and has a shorter shelf-life than pasteurized sake. Sincenamazakeis not pasteurized, it is generally characterized by a strong, fresh, sweet, and fruity flavor that is easy for beginners to enjoy. Also, because fermentation continues in the bottle, the change in flavor can be enjoyed over time, and some are effervescent due to the production of gases during fermentation.
• Genshu(Nguyên rượu) is undiluted sake. Most sake is diluted with water after brewing to lower the alcohol content from 18 to 20% down to 14–16%, butgenshuis not.
• Muroka(Vô lự quá) means unfiltered. It refers to sake that has not been carbon filtered but thathasbeen pressed and separated from the lees and thus is clear, not cloudy. Carbon filtration can remove desirable flavors and odors as well as bad ones, thusmurokasake has stronger flavors than filtered varieties.
• Jikagumi(Thẳng múc み) is sake made by squeezing mash and putting the freshly made sake directly into a bottle without transferring it to a tank. It is generally effervescent and has a strong flavor because it is filled in the bottle with as little exposure to the air as possible to the freshest liquor that continues to ferment. It is a sake that maximizes the advantages ofnamazakeorshiboritate.
• Nigorizake(Đục り rượu) is cloudy sake. The sake is passed through a loose mesh to separate it from the mash. In the production process ofnigorizake,rough cloth or colander is used to separate mash. It is not filtered after that, and there is much rice sediment in the bottle. It is generally characterized by its rich sweetness derived from rice.Nigorizakeis sometimes unpasteurizednamazake,which means that it is still fermenting and has an effervescent quality. Therefore, shaking the bottle or exposing it to high temperatures may cause the sake to spurt out of the bottle, so care should be taken when opening the bottle. When first opening the bottle, the cap should be slightly opened and then closed repeatedly to release the gas that has filled the bottle little by little.To maximize the flavor ofnigorizake,there are some tips on how to drink it. First drink only the clear supernatant, then close the cap and slowly turn the bottle upside down to mix the sediment with the clear sake to enjoy the change in flavor.
• Origarami(おりがらみ) is a sake with less turbidity thannigorizake.Origaramiis filtered differently fromnigorizakeand is filtered in the same way as ordinary sake. The reason mash lees are precipitated in the bottle is that the process of making ordinary sake, in which lees are precipitated and the supernatant is scooped up and bottled to complete the product, is omitted. Sake that is lightly cloudy likeorigaramiis also calledusunigori( mỏng đục り) orkasumizake( hà rượu ).
• Seishu(Rượu gạo), 'clear/clean sake,' is the Japanese legal definition of sake and refers to sake in which the solids have been strained out, leaving clear liquid. Thusdoburoku(see below) is notseishuand therefore are not actually sake under Japanese law. AlthoughNigorizakeis cloudy, it is legally classified asseishubecause it goes through the process of filtering through a mesh.
• Koshu(Cổ rượu) is 'aged sake'. Most sake does not age well, but this specially made type can age for decades, turning yellow and acquiring a honeyed flavor.
• Taruzake(Tôn rượu) is sake aged in wooden barrels or bottled in wooden casks. The wood used isCryptomeria(Sam,sugi), which is also known as Japanese cedar. Sake casks are often tapped ceremonially to open buildings, businesses, parties, etc. Because the wood imparts a strong flavor, premium sake is rarely used for this type.
• Shiboritate(Trá lập て), 'freshly pressed,' refers to sake that has been shipped without the traditional six-month aging/maturation period. The result is usually a more acidic, "greener" sake.
• Fukurozuri(Túi điếu り) is a method of separating sake from the lees without external pressure by hanging the mash in bags and allowing the liquid to drip out under its weight. Sake produced this way is sometimes calledshizukuzake(雫 rượu), meaning 'drip sake'.
• Tobingakoi(Đấu bình 囲い) is sake pressed into 18-liter (4.0 imp gal; 4.8 U.S. gal) bottles (tobin) with the brewer selecting the best sake of the batch for shipping.

Others

• Amazake(Cam rượu) is a traditional sweet, low- or non-alcoholic Japanese drink made from fermented rice.
• Doburoku(Rượu đục) is the classic home-brew style of sake (although home brewing is illegal in Japan). It is created by simply addingkōjimold to steamed rice and water and letting the mixture ferment. It is sake made without separating mash. The resulting sake is somewhat like a chunkier version ofnigorizake.
• Jizake(Mà rượu) is locally brewed sake, the equivalent ofmicrobrewingbeer.
• Kijōshu(Quý 醸 rượu) is sake made using sake instead of water. A typical sake is made using 130 liters of water for every 100 kilograms of rice, whilekijōshuis made using 70 liters of water and 60 liters of sake for every 100 kilograms of rice.Kijōshuis characterized by its unique rich sweetness, aroma and thickness, which can be best brought out when aged to an amber color.kijōshuis often more expensive than ordinary sake because it was developed in 1973 by the National Tax Agency's brewing research institute for the purpose of making expensive sake that can be served at government banquets for state guests. The method of making sake using sake instead of water is similar to the sake brewing method calledshioridescribed in theEngishikicompiled in 927. Because the termkijōshuis trademarked, sake makers not affiliated with the Kijōshu Association ( quý 醸 rượu hiệp hội ) cannot use the name. Therefore, when non-member sake manufacturers sellkijōshu,they use terms such assaijō jikomi( lại 醸 sĩ 込み) to describe the process.
• Kuroshu(Hắc rượu) is sake made from unpolished rice (i.e., brown rice), and is more likehuangjiu.
• Teiseihaku-shu(Thấp tinh rượu trắng) is sake with a deliberately high rice-polishing ratio. It is generally held that the lower the rice polishing ratio (the percent weight after polishing), the better the potential of the sake. Circa 2005,teiseihaku-shuhas been produced as a specialty sake made with high rice-polishing ratios, usually around 80%, to produce sake with the characteristic flavor of rice itself.
• Akaisake(Xích い rượu), literally "red sake", is produced by usingred yeast ricekōjiMonascus purpureus(Hồng khúc,benikōji),giving the sake a pink-tinted appearance similar torosé wine.

Some other terms commonly used in connection with sake:

• Nihonshu-do(Nhật Bản rượu độ), also called the Sake Meter Value or SMV

${\text{SMV}}=\left(\left|{\frac {1}{\text{specific gravity}}}\right|-1\right)\times 1443$

Specific gravityis measured on a scale weighing the same volume of water at 4 °C (39 °F) and sake at 15 °C (59 °F). The sweeter the sake, the lower the number (or more negative); the drier the sake, the higher the number. When the SMV was first used, 0 was the point between sweet and dry sake. Now +3 is considered neutral.

• Seimai-buai(Tinh mễ bộ hợp) is the rice polishing ratio (or milling rate), the percentage of weight remaining after polishing. Generally, the lower the number, the higher the sake's complexity. A lower percentage usually results in a fruitier and more complex sake, whereas a higher percentage will taste more like rice.
• Kasu(Phách) are pressed sake lees, the solids left after pressing and filtering. These are used for makingpickles,livestock feed, andshōchū,and as an ingredient in dishes like kasu soup.

Taste and flavor

The label on a bottle of sake gives a rough indication of its taste. Terms found on the label may includenihonshu-do(Nhật Bản rượu độ),san-do(Toan độ), andaminosan-do(アミノ toan độ).

Nihonshu-do(Nhật Bản rượu độ) or Sake Meter Value (SMV) is calculated from thespecific gravityof the sake and indicates the sugar and alcohol content of the sake on an arbitrary scale. Typical values are between −3 (sweet) and +10 (dry), equivalent to specific gravities ranging between 1.007 and 0.998, though the maximum range ofNihonshu-docan go much beyond that. TheNihonshu-domust be considered together withSan-doto determine the overall perception of dryness-sweetness, richness-lightness characteristics of a sake (for example, a higher level of acidity can make a sweet sake taste drier than it actually is).

San-do(Toan độ) indicates theconcentrationof acid, which is determined bytitrationwithsodium hydroxidesolution. This number equals the milliliters of titrant required to neutralize the acid in 10 mL (0.35 imp fl oz; 0.34 US fl oz) of sake.

Aminosan-do(アミノ toan độ) indicates a taste ofumamior savoriness. As the proportion ofamino acidsrises, the sake tastes more savory. This number is determined by titration of the sake with a mixture of sodium hydroxide solution andformaldehydeand is equal to the milliliters of titrant required to neutralize the amino acids in 10 mL of sake.

Sake can have manyflavor notes,such as fruits, flowers, herbs, and spices. Many types of sake have notes of apple fromethyl caproateand banana fromisoamyl acetate,particularlyginjō-shu(Ngâm 醸 rượu).In addition to apples and bananas, other fruits mentioned as flavor notes for fruity sake, especiallyginjō-shu,include melons, grapes, peaches, pineapples, citrus, etc.

Serving sake

Main article:Sake set

"Sake Ewer from a Portable Picnic Set", Japan, c. 1830–1839

In Japan, sake is served chilled (reishu(Lãnh rượu)), at room temperature (jōon(Nhiệt độ bình thường)), or heated (atsukanNhiệt lạn), depending on the preference of the drinker, the characteristics of the sake, and the season. Typically, hot sake is a winter drink, and high-grade sake is not usually drunk hot because the flavors and aromas may be lost. Most lower-quality sake is served hot because that is the traditional way, and it often tastes better that way, not so that flaws are covered up. There are gradations of temperature both for chilling and heating, about every 5 °C (9.0 °F), with hot sake generally served around 50 °C (122 °F), and chilled sake around 10 °C (50 °F), like white wine. Hot sake that has cooled (kanzamashiLạn lãnh まし) may be reheated.

Sake is traditionally drunk from small cups calledchokooro-choko(お heo khẩu) and poured into thechokofrom ceramic flasks calledtokkuri.This is very common for hot sake, where the flask is heated in hot water, and the small cups ensure that the sake does not get cold in the cup, but it may also be used for chilled sake. Traditionally one does not pour one's own drink, which is known astejaku(Tay chước), but instead members of a party pour for each other, which is known asshaku(Chước). This has relaxed in recent years but is generally observed on more formal occasions, such as business meals, and is still often observed for the first drink.

Another traditional cup is themasu,a box usually made ofhinokiorsugi,which was originally used for measuring rice. Themasuholds exactly onegō,180.4 mL (6.35 imp fl oz; 6.10 US fl oz), so the sake is served by filling themasuto the brim; this is done for chilled or room temperature sake. In some Japanese restaurants, as a show of generosity, the server may put a glass inside themasuor put themasuon a saucer and pour until sake overflows and fills both containers.

Sake is traditionally served in units ofgō,and this is still common, but other sizes are sometimes also available.

Saucer-like cups calledsakazukiare also used, most commonly at weddings and other ceremonial occasions, such as the start of the year or the beginning of akaisekimeal. In cheap bars, sake is often served at room temperature in glass tumblers and calledkoppu-zake(コップ rượu). In more modern restaurants, wine glasses are also used, and recently footed glasses made specifically for premium sake have also come into use.

Traditionally sake is heated immediately before serving, but today restaurants may buy sake in boxes that can be heated in a specialized hot sake dispenser, thus allowing hot sake to be served immediately. However, this is detrimental to the flavor. There are also a variety of devices for heating sake and keeping it warm beyond the traditionaltokkuri.

Aside from being served straight, sake can be used as a mixer forcocktails,such astamagozake,saketinis,or nogasake.Outside of Japan, thesake bomb,the origins of which are unclear,has become a popular drink in bars and Asia-themedkaraokeclubs.

The Japanese Sake Association encourages people to drink chaser water for their health, and the water is called Yawaragi-mizu.

Seasonality

Because the cooler temperatures make it more difficult for bacteria to grow, sake brewing traditionally took place mainly in winter, and this was especially true from 1673 during the Edo period until the early 20th century during the Showa era.While it can now be brewed year-round, seasonality is still associated with sake, particularly artisanal ones. The most visible symbol of this is thesugitama(Sam ngọc), a globe ofcedarleaves traditionally hung outside a brewery when the new sake is brewed. The leaves start green but turn brown over time, reflecting the maturation of the sake. These are now hung outside many restaurants serving sake. The new year's sake is calledshinshuTân rượu('new sake'), and when initially released in late winter or early spring, many brewers have a celebration known askurabirakiTàng khai き(warehouse opening). Traditionally sake was best transported in the cool spring to avoid spoilage in the summer heat, with a secondary transport in autumn, once the weather had cooled, known ashiyaoroshiLãnh tá し('cold wholesale distribution')—this autumn sake has matured over the summer.

Storage

Sake is sold in volume units divisible by 180 mL (6.3 imp fl oz; 6.1 US fl oz) (onegō), thetraditional Japanese unitforcup size.Sake is traditionally sold by thegō-sized cup, or in a 1.8 L (63 imp fl oz; 61 US fl oz) (oneshōor tengō)-sized flask (called anisshōbin,or 'one shō-measure bottle'). Today sake is also often sold in 720 mL (25 imp fl oz; 24 US fl oz) bottles, which are divisible into fourgō.Note that this is almost the same as the 750 mL (26 imp fl oz; 25 US fl oz) standard forwine bottles,which is divisible into four quarter bottles (187ml). Particularly in convenience stores, sake (generally of cheap quality) may be sold in a small 360 mL (13 imp fl oz; 12 US fl oz) bottle or a single serving 180 mL (6.3 imp fl oz; 6.1 US fl oz) (one gō) glass with a pull-off top (カップ rượukappu-zake).

Generally, it is best to keep sake refrigerated in a cool or dark room, as prolonged exposure to heat or direct light will lead to spoilage. Sake stored at a relatively high temperature can lead to the formation ofdiketopiperazine,a cyclo (Pro-Leu) that makes it bitter as it agesSake has high microbiological stability due to its high content of ethanol, but instances of spoilage have occurred. One of the microorganisms implicated in this spoilage islactic acid bacteria(LAB) that has grown tolerant to ethanol and is referred to ashiochi-bacteria.Sake stored at room temperature is best consumed within a few months after purchase.

Sake can be stored for a long time due to its high alcohol content and has no use-by dates written on the bottle or label. However, there is a best before date for good drinking, and it depends on the type of sake, with the typical twice-pasteurized sake having a relatively long best before date. According to major sake brewer Gekkeikan, the best before date when unopened and stored in a dark place at about 20 degrees Celsius (68 degrees Fahrenheit) is one year after production forfutsū-shuandhonjōzō-shu,10 months forginjō-shu,junmai-shu,and sake pasteurized only once, and up to eight months for specialnamazakethat can be distributed at room temperature.According toSawanotsuru,once pasteurized sake and unpasteurizednamazakehave a best before date of nine months after production.Some sources also state that the best before date for unpasteurizednamazakeis three to six months after production.Namazakegenerally requires refrigeration at all times.However, there are exceptions to these storage conditions, in which case the conditions are stated on the label. For example, sake under the brand nameAramasa( tân chính ) must be kept refrigerated at all times, even if it isjunmai-shu,which has been pasteurized.

Once the sake is opened, it should be kept refrigerated, as the flavor deteriorates more quickly than before opening. Best before date after opening the bottle varies depending on the source. According to sake media outlet Sake no shizuku, which interviewed several major sake production companies, the responses from all companies were nearly identical. According to the responses,junmaitype sake without added distilled alcohol has a best before date of 10 days after opening, while other types of sake with added distilled alcohol has a best before date of one month after opening.According to the international sommelier of sake certified by SSI International,ginjōtype sake, which is fermented at low temperature for a long time, has little flavor degradation for two to three days after opening and has a best before date of one week after opening. Other special designation sake andfutsū-shuhave little flavor degradation for 10 to 14 days after opening the bottle and have a best before date of one month after opening. Unpasteurizednamazakedeteriorates the fastest and should be drunk as soon as possible.

These best before dates are shortened when stored at high temperatures or in bright places, especially under sunlight or fluorescent lights that emit ultraviolet rays.On the other hand, the optimal temperature to minimize flavor degradation is minus 5 degrees Celsius (23 degrees Fahrenheit). It is also recommended that sake bottles be stored vertically. This is because if the bottle is placed horizontally, the sake is exposed to more air inside the bottle, which speeds up oxidation and may change the flavor when it comes in contact with the cap.

If these types of sake, which were clear or white at first, turn yellow or brown, it is a sign that the flavor has deteriorated. The exception is agedkoshu,which is amber in color from the time of shipment because it has been aged for several years to optimize its flavor.

Ceremonial use

Main article:Omiki

Sake is often consumed as part ofShintopurification rituals. Sake served to gods as offerings before drinking are calledo-miki(Ngự thần rượu)ormiki(Thần rượu).

In a ceremony calledkagami biraki,wooden sake casks are opened with mallets during Shinto festivals, weddings, store openings, sports and election victories, and other celebrations. This sake, callediwai-zake('celebration sake'), is served freely to all to spread good fortune.

At theNew Year,many Japanese people drink a special sake calledtoso.Tosois a sort ofiwai-zakemade by soakingtososan,akampo(traditional Japanese medicine), overnight in sake. Even children sip a portion. In some regions, the first sips oftosoare taken in order of age, from the youngest to the eldest.

OnChildren's Day,May 5, there is a custom of drinkingshōbu sake( xương bồ rượu ), which is made by cutting iris roots and leaves into thin slices and soaking them in sake, a tradition inherited fromTango no Sekku.It is believed that iris has the power to ward off evil spirits and has medicinal properties.
