Sake or
saké ( or in English and in Japanese) is a
Japanese
alcoholic
beverage made from rice.
This beverage is called
sake in English, but in
Japanese, sake (酒) or
o-sake (お酒) refers to alcoholic
drinks in general. The Japanese term for this specific beverage is
Nihonshu (日本酒), meaning "Japanese sake".
Sake is also referred to in English as
rice
wine. However, unlike true
wine, in which
alcohol is produced by fermenting the sugar naturally present in
fruit, sake is made through a brewing process more like that of
beer. To make beer or sake, the sugar needed to
produce alcohol must first be converted from starch. But the
brewing process for sake differs from beer brewing as well, notably
in that for beer, the conversion of starch to sugar and sugar to
alcohol occurs in two discrete steps, but with sake they occur
simultaneously. Additionally, alcohol content also differs between
sake, wine, and beer. Wine generally contains 9–16% alcohol and
most beer is 3–8%, whereas undiluted sake is 18–20% alcohol,
although this is often lowered to around 15% by diluting the sake
with water prior to bottling.
History
The origins of sake are unclear; however, the earliest written
reference to use of alcohol in Japan is recorded in the
Book of
Wei, of the
Records
of Three Kingdoms. This 3rd century Chinese text speaks of
the Japanese drinking and dancing. Sake is also mentioned several
times in the
Kojiki, Japan's first
written history, compiled in 712. People used sake for spiritual
functions because people who had it got a fever.
The first alcoholic drink in Japan may have been
kuchikami no
sake ("mouth-chewed sake"), which is made by chewing nuts or
grains and spitting them into a pot. The enzymes from the saliva
allow the starches to
saccharify
(convert to sugar), and then ferment. This method was also used by
Native Americans
(see
cauim,
chicha and
pulque), and inscriptions from the 14th
century BC mention Chinese millet wine (小米酒, ) being made the same
way.Though there are various opinions in the start of sake, ancient
sake was a basically sticky state of the paste as "neri sake" that
remained in Izumo and Hakata now.
Regardless, by the
Asuka period, true
sake - made from rice, water, and
kōji mold ( ,
Aspergillus oryzae) -
was the dominant alcohol. In the Heian period, sake began to be
used for religious ceremony and people seldom drank it. 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. The
Tamon-in Diary, written by abbots of Tamon-in temple from
1478 to 1618, records many details of brewing in the temple. The
diary shows that pasteurization and the process of adding
ingredients to the main fermentation mash in three stages were
established practices by this time.
In the 16th century, technique of distillation was introduced into
the Kyushu district from Ryukyu, and started brewing shochu called
"Imo - sake," sold at the central market in Kyoto. And, powerful
daimyos imported various liquors and wine from Europe, China, and
Korea.
In the 18th century,
Engelbert
Kaempfer and
Isaac Titsingh
published 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.
During the
Meiji Restoration, laws
were written that allowed anybody with the money and know-how to
construct and operate their own sake breweries. Around 30,000
breweries sprang up around the country within a year. However, as
the years went by, the government levied more and more taxes on the
sake industry and slowly the number of breweries dwindled to
8,000.
Most of the breweries that grew and survived this period were set
up by wealthy landowners. Landowners who grew rice crops would have
rice left over at the end of the season and, rather than letting
this stash of rice go to waste, would ship it to their breweries.
The most successful of these family breweries still operate
today.
During the 20th century, sake-brewing technology grew by leaps and
bounds. The government opened the sake-brewing research institute
in 1904 and, in 1907 the very first government-run sake
tasting/competition was held. 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 being devoid of
bacterial problems. (The government considered wooden barrels 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 barrels means that a
significant amount of sake is lost to evaporation (somewhere around
3%), which could have otherwise been taxed. This was the end of the
wooden-barrel age of sake and the use of wooden barrels in brewing
was completely eliminated.
In Japan, sake has long been taxed by the federal government. In
1898 this tax brought in about 55 million yen out of a total of
about 120 million yen, about 46% of the government's total direct
tax income
During the
Russo-Japanese War in
1904–1905, the government banned the home brewing of sake. At the
time, sake made up an astonishing 30% of Japan's tax revenue. Since
home-brewed sake is tax-free sake, the logic was that by banning
the home brewing of sake, sales would go up, and more tax money
would be collected. This was the end of home-brewed sake, and the
law remains in effect today even though sake sales now make up only
2% of government income.
When
World War II brought rice
shortages, the sake-brewing industry was dealt a hefty blow as the
government clamped down on the use of rice for brewing. As early as
the late 17th century, it had been discovered that small amounts of
alcohol could be added to sake before pressing to extract aromas
and flavors from the rice solids, but during the war, pure alcohol
and
glucose were added to small quantities
of rice mash, increasing the yield by as much as four times. 75% of
today's sake is made using this technique, left over from the war
years. There were even a few breweries producing "sake" that
contained no rice at all. Naturally, the quality of sake during
this time suffered greatly.
After the war, breweries slowly began to recover, and the quality
of sake gradually went up. However, new players on the scene —
beer, wine, and spirits — became very popular in Japan, and in the
1960s beer consumption surpassed sake for the first time. Sake
consumption continued to go down while, in contrast, the quality of
sake steadily improved.
Recent
increases in the popularity of shōchū also bode ill for the
future of sake in its native country.
Today, sake has become a world beverage with a few breweries
springing up in China, Southeast Asia, South America, North
America, and Australia. More breweries are also turning to older
methods of production.
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.
And now, 1 October is provided the day of sake (Nihon-shu).
Brewing

Moromi, the main mash
Sake is produced by the multiple parallel fermentation of
rice. The rice is polished to remove the
protein and
oils from the
exterior of the rice grains, leaving behind
starch. A more thorough milling leads to fewer
congeners and generally a more desirable
product.
Newly polished rice is allowed to "rest" until it absorbs enough
moisture from the air not to crack when immersed in water. After
this resting period, the rice is washed clean of the rice powder
produced during milling and is steeped in water. The length of the
soak depends on the degree to which the rice was polished, from
several hours or even overnight for an ordinary milling to just
minutes for highly polished rice.
After soaking, the rice is boiled in a large pot or it is steamed
on a conveyor belt. The degree of cooking must be carefully
controlled; overcooked rice will ferment too quickly for flavors to
develop well and undercooked rice will only ferment on the outside.
The steamed rice is then cooled and divided for different
uses.
Some of the steamed rice is taken to a culture room and inoculated
with
kōji mold (麹,
Aspergillus oryzae). The mold-laden rice
is itself known as kōji and is cultivated until the growth of the
fungus reaches the desired level. This takes about two days.
When the kōji is ready, the next step is to create the starter
mash, known as
shubo (酒母), or colloquially,
moto
(酛). Kōji rice, water, and
yeast are mixed
together, and in the modern method,
lactic
acid is added to inhibit unwanted bacteria (in slower
traditional methods, lactic acid occurs naturally). Next, freshly
steamed rice is added and the yeast is cultivated over 10 to 15
days (in the modern method).
When the starter mash is ready, steamed rice, water, and more kōji
are added once a day for three days, doubling the volume of the
mash each time. Staggering things this way allows the yeast to keep
up with the increased volume. The mixture is now known as the main
mash, or
moromi (醪, also written 諸味).
The main mash then ferments. This takes two to six weeks. With
high-grade sake, fermentation is deliberately slowed by lowering
the temperature to 10°C (50°F) or less.
Unlike
malt for beer, rice for sake does not
have the necessary
amylase to convert starch
to sugar and so must undergo a process of
multiple
fermentation, in which starch is converted to sugar by the
kōji, and sugar is converted to alcohol by yeast. With sake these
two processes happen at the same time, not as separate steps, so
sake is said to be made by multiple
parallel
fermentation.
After fermentation, sake is pressed to separate the liquid from the
solids. With some sake, a small amount of distilled alcohol, called
brewer’s alcohol (醸造アルコール), is added before pressing in order to
extract flavors and aromas that would otherwise stay in the solids.
With cheap sake, a large amount of brewer’s alcohol might be added
to increase the volume of sake produced. Next, the remaining lees
(a fine sediment) are removed, and the sake is carbon filtered and
pasteurized. The sake is allowed to rest and mature and then it is
usually diluted with water to lower the alcohol content from around
20% to 15% or so, before finally being bottled.
Varieties
There are two basic types of sake:
futsū-shu ( )
and
tokutei meishō-shu ( ). Futsū-shu, "ordinary
sake," is the equivalent of
table wine
and accounts for the majority of sake produced. Tokutei meishō-shu,
"special designation sake," refers to premium sakes distinguished
by the degree to which the rice is polished and the added
percentage of brewer's alcohol or the absence of such
additives.
The three types of special designation sake
- Honjōzō-shu ( ), in which a slight amount of
brewer's alcohol is added to the sake before pressing, in order to
extract extra flavors and aromas from the mash. This term was
created in the late 1960s to distinguish it, a premium sake, from
cheaply made liquors to which large amounts of distilled alcohol
were added simply to increase volume. Sake with this designation
must be made with no more than 116 liters of pure alcohol added for
every 1,000 kilograms of rice.
- Junmai-shu ( ), "pure rice sake," made from
only rice, water and kōji, with no brewer's alcohol or other
additives. Before 2004, the Japanese government mandated that
junmai-shu must be made from rice polished down to 70% or less of
its original weight, but that restriction has been removed.
- Ginjō-shu ( ), made from rice polished to 60%
or less of its original weight. Sake made from rice polished to 50%
or lower is called daiginjō-shu ( ).
The term
junmai can be added to
ginjō or
daiginjō, resulting in
junmai ginjō and
junmai daiginjō. However, as distilled alcohol is added in
small amounts to ginjō and daiginjō to heighten the aroma, not to
increase volume, a junmai daiginjō is not necessarily a better
product than a daiginjō made with brewer's alcohol.
In addition to "ordinary" sake and the special designations, there
are many more types of sake.
Three ways to make the starter mash
- Kimoto (生酛) is the traditionally orthodox
method for preparing the starter mash, which includes the laborious
process of grinding it into a paste. This method was the standard
for 300 years, but it's rare today.
- Yamahai (山廃) is a simplified version of the
kimoto method, introduced in the early 1900s. Yamahai skips the
step of making a paste out of the starter mash. That step of the
kimoto method is known as yama-oroshi, and the full name for
yamahai is “yama-oroshi haishi” (山卸廃止), meaning “discontinuation of
yama-oroshi.” While the yamahai method was originally developed to
speed production time, it is slower than the modern method and is
now used only in specialty brews for the earthy flavors it
produces.
- Sokujō (速醸), "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. Sokujō sake tends to have a
lighter flavor than kimoto or yamahai.
Different handling after fermentation

Nigori, or unfiltered sake.
- Namazake (生酒) is sake that has not been
pasteurized. It requires refrigerated
storage and has a shorter shelf-life than pasteurized sake.
- Genshu (原酒) is undiluted sake. Most sake is
diluted with water after brewing, to lower the alcohol content from
18-20% down to 14-16%, but genshu is not.
- Muroka (無濾過) means unfiltered. Note that this
refers to sake that hasn’t 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 muroka sake has stronger
flavors than filtered varieties.
- Nigorizake (濁り酒) is cloudy sake. The sake is
passed through a loose mesh to separate it from the mash. It isn't
filtered thereafter 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.
- Seishu (清酒), "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
nigorizake and doburoku (see below) are not seishu and
therefore aren't actually sake under Japanese law. However,
nigorizake can get seishu status by being strained clear and having
lees put back in afterward.
- Koshu (古酒) 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 (樽酒) is sake aged in wooden barrels
or bottled in wooden casks. The wood used is Cryptomeria (杉, sugi), which is also
inaccurately known as Japanese cedar. Sake casks are often broken
open ceremonially for the opening of buildings, businesses,
parties, etc. Because the wood imparts a strong flavor, premium
sake is rarely used for this type.
- Shiboritate (搾立て), "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 (袋吊り) 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 own weight.
Sake produced this way is sometimes called shizukazake
(雫酒), meaning "drip sake."
- Tobingakoi (斗瓶囲い) is when sake is pressed into
18-liter bottles ("tobin") and the brewer selects the best sake of
the batch for shipping.
Others
- Doburoku (濁酒) is the classic home-brew style
of sake (although home brewing is illegal in Japan). It is created
by simply adding kōji mold to steamed rice and water and
letting the mixture ferment. The resulting sake is somewhat like a
chunkier version of nigorizake.
- Kuroshu (黒酒) is sake made from unpolished rice
(i.e. brown rice), more like Chinese rice
wine.
- Teiseihaku-shu (低精白酒) 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. However,
beginning around 2005, teiseihaku-shu has 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.
Some other terms commonly used in connection with sake:
- Nihonshu-do ( ), also called the Sake Meter Value, or
SMV SMV = (|1/specific gravity|−1) × 1443 Specific gravity is measured on a scale
weighing the same volume of water at 4°C and sake at 15°C. The
sweeter the sake is, the lower the number gets. When the SMV was
first used, 0 was designated the point between sweet sake and dry
sake. Now +3 is considered neutral.
- Seimai-buai (精米歩合) is the rice polishing ratio, the
percentage of weight remaining after polishing. Generally, the
lower the number, the better the sake's potential. A lower
percentage usually results in a fruitier sake, whereas a higher
percentage will taste more like rice.
- Kasu ( ) are pressed sake
lees, the solids left after pressing and filtering. These are used
for making tsukemono pickles, livestock
feed, and shōchū, and as an
ingredient in dishes like kasu soup.
Serving sake
Sake can be served in a wide variety of cups; here is a
sakazuki (a flat, saucer-like cup), an
ochoko (a
small, cylindrical cup), and a
masu (a wooden, box-like
cup).
In Japan sake is served chilled, at room temperature, or heated,
depending on the preference of the drinker, the quality of the
sake, and the season. Typically, hot sake is a winter drink, and
high-grade sake is not drunk hot, because the flavors and aromas
will be lost. This masking of flavor is the reason that low-quality
sake is often served hot.
Sake is usually drunk from small cups called
choko and
poured into the choko from ceramic flasks called
tokkuri.
Saucer-like cups called
sakazuki are also used, most
commonly at weddings and other ceremonial occasions. Recently,
footed glasses made specifically for premium sake have also come
into use.
Another traditional cup is the
masu, a box usually made of
hinoki or
sugi, which was originally used for
measuring rice. In some Japanese restaurants, as a show of
generosity, the server may put a glass inside the masu or put the
masu on a saucer and pour until sake overflows and fills both
containers.
Aside from being served straight, sake can be used as a mixer for
cocktails, such as
tamagozake,
saketinis,
nogasake, or the
sake bomb.
Storage
In general, 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 room temperature is best consumed within a
few months after purchase.
After opening the bottle of sake, it is best consumed within 2 or 3
hours. It is possible to store in the refrigerator, but it is
recommended to finish the sake within 2 days. This is because once
premium sake is opened, it begins to oxidize which affects the
taste. If the sake is kept in the refrigerator for more than 3
days, it will lose its "best" flavor. However, this does not mean
it should be disposed of if not consumed. Generally, sake can keep
very well and still taste just fine after weeks in the fridge. How
long a sake will remain drinkable depends on the actual product
itself, and whether it is sealed with a wine vacuum top.
Ceremonial use
Sake is often consumed as part of
Shinto
purification rituals (compare with the use of grape
wine in the
Christian Eucharist). During
World
War II,
kamikaze pilots drank sake
prior to carrying out their missions.
In a ceremony called
kagami
biraki, wooden casks of sake are opened with mallets
during Shinto festivals, weddings, store openings, sports and
election victories, and other celebrations. This sake, called
iwai-zake ("celebration sake"), is served freely to all to
spread good fortune.
On the
New Year many Japanese people drink
a special sake called
toso. Toso is a sort of
iwai-zake made by soaking
tososan, a Chinese powdered
medicine, overnight in sake. Even children sip a portion. In some
regions, the first sipping of toso is taken in order of age from
younger to older.
