Sake & brews ── Nihonshu (sake)
Doburoku
Doburoku — unfiltered home-style rice brew
A brew made from rice, koji, and water and fermented, but never pressed or filtered. Because nothing is strained out, it keeps a hint of the rice's starch and sugar and a gentle sweetness, and the law classifies it not as sake but as a separate 'other brewed alcohol.'
What it's made of
Doburoku is fermented from rice, koji, and water but never pressed or filtered afterward. Because the mash is drunk as is, unfermented rice starch and sugars that never fully broke down remain, said to give it a gentle sweetness. Its alcohol content, roughly 14 to 17%, sits close to ordinary sake, though that sweetness is said to make it easy to drink more than intended.
How it's made
With no pressing step at all, it stays a thick, cloudy white. There's no press to separate liquid from lees the way sake production does, and the rice grains themselves are often left right in the container as it's bottled — how far fermentation has progressed shapes just how sweet or sour any given batch turns out.
Why it took this shape
It's said to be one of the oldest forms of rice brewing, dating back to roughly when rice cultivation itself arrived. Once the sake tax became a pillar of national revenue in the Meiji era, home brewing is said to have been banned as a threat to licensed brewers' business. A 2002 special-zone reform later allowed brewing and local sale again, but only within designated areas.

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.
Ingredients and dishes from this land
Contrast
- NihonshuJapan's traditional brewed drink, made mainly from rice, koji, and water. Milling ratio, how the starter mash is raised, and whether the sake is pasteurized all branch it into a wide range of styles, and differences in water and climate are said to have shaped distinct regional characters.
- NigorizakeSake pressed through a coarse cloth so that flecks of rice sediment are deliberately left behind. Because it does go through a pressing step, unlike doburoku, it's legally classed as sake, and bottled while fermentation is still active, it can carry a natural fizz.
