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 the '' Book of Wei'' in the '' Records of the Three Kingdoms''. This 3rd-century Chinese text speaks of Japanese drinking and dancing. are mentioned several times in the '' Kojiki'', Japan's first written history, which was compiled in 712.

(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, temples and shrines began to brew sake, and they became the main centers of production for the next 500 years.


Muromachi period

Before the 1440s in the Muromachi period (1333-1573), the Buddhist temple Shōryaku-ji invented 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 of (). Until then, most sake had been with a different process from today's, but after that, clear was established. The main production methods established by Shōryaku-ji are the use of all polished rice (''morohaku zukuri'', 諸白造り), three-stage fermentation (''sandan zikomi'', 三段仕込み), brewing of starter mash using acidic water produced by lactic acid fermentation (''bodaimoto zukuri'', 菩提酛づくり), and pasteurization (''hiire'', 火入れ). This method of producing starter mash is called ''bodaimoto'', which is the origin of . These innovations made it possible to produce sake with more stable quality than before, even in temperate regions. These things are described in (), the oldest known technical book on sake brewing written in 1355 or 1489, and (), a diary written between 1478 and 1618 by monks of

Temple in the Muromachi period. A huge tub ( :ja:桶) with a capacity of 10 '' koku'' (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 3 ''koku'' at 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 of shōchū, called "Imo–sake" started and was sold at the central market in

(1603–1867), a brewing method called () 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. The Nada-Gogō area in Hyōgo Prefecture, the largest producer of modern sake, was formed during this period. When the population of Edo, modern-day

In the Genroku era, when the culture of the '' chōnin'' class, the common people, prospered, the consumption of sake increased rapidly, and large quantities of '' taruzake'' (樽酒) were shipped to Edo. 80% of the sake drunk in Edo during this period was from Nada-Gogō.

From the Meiji era to the early Shōwa era

Starting around the beginning of the Meiji era (1868-1912), the technique for making sake began to develop rapidly. Breeding was actively carried out in various parts of Japan to produce sake rice optimized for sake brewing. ''Ise Nishiki'' developed in 1860, ''Omachi'' ( :ja:雄町) developed in 1866 and ''Shinriki'' developed in 1877 are the earliest representative varieties. In 1923,

, 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 and ''Omachi'' fourth. 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 developed '' yamahai'', a new method of making starter mash, and in 1910, a further improvement, '' sokujō'', was developed. Yeast strains 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:桶) 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 the First Sino-Japanese War and in preparation for the
Russo-Japanese War The Russo-Japanese War ( ja, 日露戦争, Nichiro sensō, Japanese-Russian War; russian: Ру́сско-япóнская войнá, Rússko-yapónskaya voyná) was fought between the Empire of Japan and the Russian Empire during 1904 and 1 ...
. 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 aged , which had been popular until then, and it was only in 1955 that sake breweries began to make again. When

brought 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 and

were 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 as '' futsū-shu''.「醸造アルコール」って何? なぜ使われているの.

Since the mid-Showa era

Postwar, breweries slowly recovered, and the quality of sake gradually increased. The term (), which means carefully brewed sake, first appeared at the end of the Edo period, and the term (), which has the same meaning, first appeared in 1894. However, '' ginjō-shu'' (), 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,

, the most suitable sake rice for brewing ''ginjō-shu'', became the recommended variety of Hyogo Prefecture. Around 1953, the "Kyokai yeast No. 9" (, ) 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 of ''ginjō-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-shu'' with a fruity flavor was created. At that time, ''ginjō-shu'' was a special sake exhibited at competitive exhibitions and was not on the market. From around 1975, ''ginjō-shu'' began to be marketed and was widely distributed in the 1980s, and in 1990, with the definition of what can be labeled as ''ginjō-shu'', more and more brewers began to sell ''ginjō-shu''. The growing popularity of ''ginjō-shu'' has prompted research into yeast, and many yeasts with various aromas optimized for ''ginjō-shu'' have been developed.「吟醸」のあゆみ 特別に吟味して醸造する酒として、長年かけ洗練.

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. Sake exports in 2021 were six times larger than those in 2009. As of 2021, the value of Japan's liquor exports was about 114.7 billion yen, with

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 various microorganisms living 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.

Production


Rice

The rice used for brewing sake is called () ('sake rice'), or officially () ('sake-brewing suitable rice'). There are at least 123 types of sake rice in Japan.資料2 酒造好適米の農産物検査結果(生産量)と令和元年産の生産量推計(銘柄別).

, Gohyakumangoku ( :ja:五百万石), Miyama Nishiki ( :ja:美山錦) and Omachi ( :ja:雄町) 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.酒米の王様「山田錦」.

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 () 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 the (, ). 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 making rice crackers, Japanese sweets (i.e.

), 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 of '' ginjō''. 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, called () (see Glossary 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.


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.

While soft water will typically yield sweeter sake, hard water with a higher nutrient content is known for producing drier-style sake. The first region known for having great water was the Nada-Gogō in Hyōgo Prefecture. A particular water source called was 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.

Fermentation

Sake fermentation is a three-step process called . The first step, called , involves steamed rice, water, and being added to the yeast starter called : a mixture of steamed rice, water, kōji, and yeast. This mixture becomes known as the (the main mash during sake fermentation). The high yeast content of the promotes the fermentation of the ''.'' On the second day, the mixture stands for a day to let the yeast multiply. The second step (the third day of the process), called , involves the addition of a second batch of , steamed rice, and water to the mixture. On the fourth day of the fermentation, the third step of the process, called , takes place. Here, the third and final batch of kōji, steamed rice, and water is added to the mixture to complete the three-step process. The fermentation process of sake is a multiple parallel fermentation unique to sake. Multiple parallel fermentation is the conversion of starch into glucose followed by immediate conversion into alcohol. This process distinguishes sake from other liquors 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 the fungus, 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 liquor. After the fermentation process is complete, the fermented is pressed to remove the sake lees and 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 60–90 days (2–3 months), while the fermentation alone can take two weeks. On the other hand, '' ginjō-shu'' takes 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.

Varieties


Special-designation sake

There are two basic types of sake: and . is the equivalent of table wine and accounts for 57% of sake production as of 2020. refers 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. () is sake made using a special method called ''ginjō-zukuri'' (), in which rice is slowly fermented for about 30 days at a low temperature of 5 to 10 degrees Celsius (41 to 50 degrees

'' namazake''. Therefore, it is recommended that sake with the name ''ginjō'' be transported and stored in cold storage. It's also recommended to drink chilled to maximize its fruity flavor. Generally () 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 labeled , has an appropriate amount of distilled alcohol added. The maximum amount of distilled alcohol added to is 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.「清酒の製法品質表示基準」の概要.

.
Generally, it is often misunderstood that the addition of 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 the ''Zenkoku shinshu kanpyōkai'' (全国新酒鑑評会, National New Sake Appraisal), the largest sake contest, had distilled alcohol added, and 91.1% of the winning sake had it added. It should be noted, however, that the most important aspect of the contest is the brewing technique, not whether it tastes and flavor 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 of ''ginjō''. 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 the

Ways to make the starter mash

* () 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 as . This method was the standard for 300 years, but it is rare today. * () is a simplified version of the method, introduced in the early 1900s. skips the step of making a paste out of the starter mash. That step of the method is known as , and the full name for is (), meaning 'discontinuation of . While the method was originally developed to speed production time compared to the method, it is slower than the modern method and is now used only in specialty brews for the earthy flavors it produces. * (), '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. sake tends to have a lighter flavor than or .

. It requires refrigerated storage and has a shorter shelf-life than pasteurized sake. Since is 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. * () is undiluted sake. Most sake is diluted with water after brewing to lower the alcohol content from 18–20% down to 14–16%, but is not. * () means unfiltered. It refers to sake that has not been carbon filtered but which ''has'' been 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, thus sake has stronger flavors than filtered varieties. * () 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 of or . * ''Nigorizake'' () is cloudy sake. The sake is passed through a loose mesh to separate it from the mash. In the production process of , rough cloth or colander is used to separate mash. It is not filtered after that, and there is much rice sediment in the bottle. Before serving, the bottle is shaken to mix the sediment and turn the sake white or cloudy. It is generally characterized by its rich sweetness derived from rice. * () is a sake with less turbidity than . is filtered differently from and 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 like is also called (薄濁り) or (霞酒). * (), '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. Thus (see below) is not and therefore are not actually sake under Japanese law. Although is cloudy, it is legally classified as because it goes through the process of filtering through a mesh. * () is 'aged sake'.

'' (, ), 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. * (), '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. * () 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 called (), meaning 'drip sake'. * () is sake pressed into bottles () with the brewer selecting the best sake of the batch for shipping.

Serving sake

In Japan, sake is served chilled (), at room temperature (), or heated ( ), 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 , with hot sake generally served around , and chilled sake around , like white wine. Hot sake that has cooled ( ) may be reheated. Sake is traditionally drunk from small cups called or () and poured into the from ceramic flasks called . 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 as (), but instead members of a party pour for each other, which is known as (). 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.

leaves 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 called ('new sake'), and when initially released in late winter or early spring, many brewers have a celebration known as (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 as ('cold wholesale distribution')—this autumn sake has matured over the summer. There is not traditionally a notion of vintage of sake—it is generally drunk within the year, and if aged, it does not vary significantly from year to year. Today, with influence from

After opening a bottle of sake, it is best consumed within two or three hours. It is possible to store sake in the refrigerator, but it is recommended to consume it within two days. When premium sake is opened, it begins to oxidize, which affects the taste. If the sake is kept in the refrigerator for over three days, it will lose its "best" flavor. This does not mean it should be disposed of if not consumed. Generally, sake can keep very well and taste good after weeks in the refrigerator. How long a sake will remain drinkable depends on the quality of the product and whether it is sealed with a vacuum top to decrease oxidation.
