Fermentation
Yeast converts sugars into alcohol. Sake and wine are fermented drinks.
Sake, wine, shochu, whisky and umeshu: compare their ingredients and production methods, then explore each world.
Compare the drinks ↓
| Drink | Main ingredients | Process |
|---|---|---|
| Sake | Rice, rice koji, water | Saccharification and fermentation |
| Wine | Grapes | Fermentation |
| Shochu | Sweet potato, barley, rice and more; koji, water | Fermentation → distillation |
| Whisky | Grains, including malted barley; water | Saccharification → fermentation → distillation → cask maturation |
| Umeshu | Ume fruit, sugar, alcohol | Maceration (traditional method) |
Yeast converts sugars into alcohol. Sake and wine are fermented drinks.
A fermented liquid is heated and the vapour is cooled and collected. This process is used to make shochu and whisky.
Fruit is steeped in alcohol to extract its flavours. Traditional umeshu combines ume fruit, sugar and alcohol.
A fermented rice drink
In sake brewing, koji enzymes turn rice starch into sugars, which yeast ferments. Sake is not a distilled spirit like shochu.
Junmai is made with white rice, rice koji and water. Terms such as junmai and ginjo are useful starting points for reading a label.
Explore sake in detail →A fermented grape drink
Wine is made when yeast converts grape sugars into alcohol. White and red winemaking differ in how the grape skins are handled, among other steps.
The JAPANITIES wine guide starts with Bordeaux: regions, grapes, the Left and Right Banks, and classifications.

Honkaku shochu is made by fermentation followed by distillation. Ingredients include sweet potatoes, barley and rice.
Rice shochu and sake are different drinks: the former is distilled, while sake is a fermented drink without that distillation step.
A grain spirit matured in wooden casks
Whisky production begins with grains and proceeds through saccharification, fermentation and distillation, followed by maturation in wooden casks.
Whisky and shochu can share ingredients but use different production methods. Distillation and maturation help explain the differences.

A liqueur made with ume fruit
Traditional umeshu is made by steeping ume fruit with sugar in alcohol. Its production differs from fermenting grapes to make wine.
Honkaku umeshu is made only with ume fruit, sugar and alcohol, without added acidifiers, flavourings or colouring.

Sake is made from polished rice, rice koji and water; some types also add brewer’s alcohol. Unlike wine, the rice starch must first be converted to sugar by koji, and saccharification and fermentation run in parallel in the same tank.
Junmai means no brewer’s alcohol was added; ginjo relates to polishing (60% or less) and a specific brewing method. They are separate axes, which is why “junmai ginjo” exists.
No. It means 60% of the grain’s weight remains and 40% was milled away. A lower number means more polishing, but the number alone does not decide the taste.
Both. The JSS suggests chilled 8–15°C, room temperature 15–25°C and warmed 40–50°C. The best temperature depends on the bottle, so follow the brewery’s guidance.
Ingredients (rice and koji versus grapes), the source of sugar and the fermentation process. Sake uses multiple parallel fermentation. On labels, sake shows grade and polishing; wine shows appellation, grape and classification.
