Shōchū is a Japanese distillate usually around 25% alcohol. It is obtained by distilling fermented raw materials — barley, sweet potato, rice, or another product — rather than by simple fermentation like sake.

How does shōchū differ from sake?

Sake is fermented, shōchū is distilled — these are different production methods, not a strong and a weak version of one drink. They also differ in how they are served: shōchū is more often diluted with hot or cold water, while sake is drunk undiluted.

What is shōchū made from?

Most often from barley, sweet potato, or rice, less often from buckwheat or cane sugar. The type of shōchū is usually named directly after the raw material: mugi-shōchū from barley, imo-shōchū from sweet potato. Cane sugar kokutō-shōchū is by law produced only on the Amami Islands.

How strong is shōchū?

Usually around 25% alcohol, though by law single distillation allows up to 45% and continuous distillation up to 36%. The final strength in the bottle is most often below the upper limit and is chosen for the specific variety.

How is shōchū drunk in Japan?

Most often diluted — with cold water (水割り) or hot water (お湯割り), less often with ice. This dilution is customary precisely because of shōchū's higher strength compared to fermented drinks like sake or beer.

What is honkaku-shōchū?

Honkaku-shōchū (本格焼酎) is single-distilled shōchū made with koji and no additives other than water: a category that by law preserves the flavor and aroma of the original raw material. It is contrasted with continuously distilled shōchū — a more neutral and purified spirit.

Shōchū: the Japanese spirit that has nothing to do with sake

Shōchū is a Japanese distillate usually around 25% alcohol, still often confused with strong sake, though they are different drinks. Sake is fermented, while shōchū is distilled: the raw material is first fermented, then the alcohol is distilled from it. The raw materials are barley, sweet potato, rice, buckwheat, or cane sugar, and the main production region is the island of Kyushu, especially Kagoshima and Oita.

Shōchū is often called 'Japanese vodka' or 'strong sake,' but both comparisons are inaccurate: the drink has its own technology, its own raw materials, and its own history, which began noticeably earlier than is commonly thought. Let's look at how shōchū differs from sake at the production level, what types exist depending on the raw material, and what the two legal classes of distillation mean. Separately, we'll cover a find with an inscription nearly five hundred years old.

A distilled drink, not strong sake

The main thing to know about shōchū right away: sake is fermented, and shōchū is distilled, and these are two fundamentally different drinks, not a strong and a weak version of the same thing. The confusion arises because both are made from rice and both are called Japanese alcohol, though their technology is completely different. Hence the difference in strength: shōchū is usually around 25% alcohol, noticeably higher than sake.

Where the higher alcohol content comes from

Shōchū gets its strength not through fermentation, as sake or beer does, but through distillation: the raw material is first fermented, then heated and the alcohol vapors are collected separately from the rest of the liquid. It is distillation that allows shōchū to be stronger than fermented drinks without adding pure alcohol.

Barley, sweet potato, rice: the raw material determines the type of shōchū

The type of shōchū is almost always named after the raw material from which it was distilled:

麦焼酎 (mugi-shōchū) — from barley, one of the most common types.
芋焼酎 (imo-shōchū) — from sweet potato, especially characteristic of Kagoshima.
米焼酎 (kome-shōchū) — from rice, closest in raw material to sake, but distilled, not fermented.
黒糖焼酎 (kokutō-shōchū) — from cane sugar; by a special provision of law, it may only be produced on the Amami Islands.
蕎麦焼酎 (soba-shōchū) — from buckwheat, a rarer type.

Kyushu is the main production region

The main geography of shōchū is the island of Kyushu, primarily Kagoshima and Oita prefectures: most producers are concentrated there, and local varieties like imo-shōchū developed there as well. Cane sugar 黒糖焼酎, meanwhile, is made exclusively in the Amami archipelago — the only place in Japan where the law permits distilling shōchū from sugar without classifying it as rum.

Sake is drunk differently from shōchū: the main confusion

Besides the production method, shōchū and sake differ in strength, raw materials, and how they are served at the table. Shōchū is usually diluted — with cold water (水割り, mizuwari) or hot water (お湯割り, oyu-wari), and sometimes drunk with ice; sake is usually served undiluted, warm or chilled depending on the variety.

Why they are still confused

Both drinks are made from rice and rice koji, both accompany the Japanese table, and both are translated into English by the general word 'sake' or 'Japanese alcohol' — hence the confusion. But from a production standpoint, they are such different categories that comparing them by strength is as inaccurate as comparing wine and cognac as 'two kinds of wine.'

Two classes of distillation and an inscription nearly five hundred years old

Under the liquor tax law, shōchū is divided into two classes by distillation method. 単式蒸留焼酎 (single, 'pot' distillation) — up to 45% alcohol, retains the flavor and aroma of the raw material; from this class, 本格焼酎 (honkaku-shōchū) is distinguished — shōchū with added koji, without any additives other than water. 連続式蒸留焼酎 (continuous distillation) — up to 36% alcohol, yields a much more neutral, purified spirit.

蒸 — значение: to steam, to evaporate, to heat with steam — онъёми: ジョウ、セイ — кунъёми: む.す、む.れる、む.らす — 13 штрих(ов). 蒸 — 'to steam, to evaporate': the main difference between shōchū and sake in one character. 蒸留酒 (jōryūshu) 'distilled spirit' — the category that includes shōchū, as opposed to 醸造酒 (jōzōshu) 'fermented' sake. The same character appears in 蒸留 (jōryū) 'distillation' and 蒸気 (jōki) 'steam.' The word 焼酎 itself does not contain this character: it has 焼 'to roast' and 酎 'strong, repeatedly purified alcohol.'

Write 蒸 along the guides — the 'distillation' character that distinguishes shōchū from fermented sake.

The earliest written mention

The earliest known written mention of the word '焼酎' is a 1559 inscription on a wooden beam of the Koriyama Hachiman Shinto shrine in the city of Isa, Kagoshima Prefecture. Two carpenters repairing the roof left on a hidden part of the beam a complaint that the temple's abbot had never once treated them to shōchū for the entire job — and so, by chance, the oldest record of this word was preserved.
