Junmai-shu
Junmai — sake brewed from rice, koji, and water alone
Sake made from nothing but rice, koji, and water, with no added brewing alcohol. Without that extra ingredient to lean on, the rice's own richness and weight are said to come through directly, and the law sets no fixed milling requirement — the most rice-forward of the officially defined categories.
What it's made of
The only ingredients are rice, koji, and water — not a drop of added brewing alcohol. Without that extra ingredient to fall back on, differences in rice variety and milling are said to come through directly in the cup, often giving a fuller rice sweetness, a somewhat heavier body, and a finish that lingers after swallowing. It's described as a sake for tasting the character of rice itself, precisely because rice is all there is, and is said to hold up well when warmed.
How it's made
The law sets no fixed milling ratio for this category, though many breweries polish down to around 70%, and the koji rice alone must make up at least 15% of the total rice by weight. With no added alcohol available to lighten the profile or smooth out rough notes, how a brewery manages the mash's temperature and times the pressing is said to show through directly, quirks and all. The quality of the brewing water and how the koji itself is built are also said to shape the sake's backbone.
Why it took this shape
Sake cut with added brewing alcohol was once the more common style on the market, and rice-only sake is said to have actually been the minority style for a time. Junmai is said to have been set apart as its own official category only when the naming system was reorganized in 1989, the name chosen as a return to sake's oldest form — brewed from rice alone. The category has since been treated as the one that puts a rice's own character front and center, and its breadth — holding its shape whether served cold or warmed — is said to be part of why it caught on.

Dishes in the same style
- Akita no SakeAkita sake, brewed with soft water in deliberate contrast to Nada's hard water, aiming for a mellow, delicate character. Breweries buried in snow are said to gain a natural insulating effect from it, a tradition of slow, low-temperature fermentation built around that climate.
- Daiginjo-shuSake made from rice milled to 50% or less with brewing alcohol added — among the officially defined categories, the deepest level of milling, aimed at a pronounced aroma and light body, born of elaborate brewing techniques honed for tasting competitions.
