Junmai Daiginjo-shu
Junmai daiginjo — rice-only sake milled to 50% or less
Sake made from rice alone, milled down to 50% or less of its original size — over half the grain polished away, leaving little off-flavor and, combined with slow low-temperature fermentation, a pronounced aroma. Considered the deepest-milled of the officially defined categories.
What it's made of
Only rice, koji, and water go in, with the rice milled down to 50% or less of its original size. Polishing away more than half the grain removes most of the protein and fat that can cause off-flavors, tending to leave a fragrant, clean profile — the deepest level of milling among the officially defined categories, leaving barely a trace of the grain's original shape. It's often the bottle chosen for gifts and celebrations.
How it's made
Ginjo brewing techniques hold the mash at a lower temperature for longer than usual. The more deeply the rice is polished, the harder koji-making and mash management are said to become, and handling such small, worn-down grains calls for finer adjustments to steaming and koji growth. With no brewing alcohol added at all, the sake's outline is said to be shaped entirely by the rice and koji themselves, letting each brewery's individual touch show through.
Why it took this shape
Improvements in rice-milling technology are said to have made this level of polishing possible in the first place. The 50%-or-less standard with no added alcohol was set in the 1989 reorganization, and the category is said to have emerged from chasing the same rule of thumb — deeper polishing, less off-flavor — even within the rice-only junmai line, arriving as one of the later additions to the naming system.

- Junmai Ginjo-shuSake made purely from rice milled down to 60% or less, with no added alcohol. Fermented slowly at low temperature under what's called ginjo brewing, the style is said to bring out fruit-like aromas while keeping the rice sweetness close to that of junmai.
