Sake Grade Levels
Sake grade levels are determined by the percentage the rice is milled before the brewing process. In general, the more you polish (or mill) the rice, the higher the quality. The brewing process for higher grade sake is also more labor intensive and most steps are commonly done by hand and over longer time periods.

Junmai Daiginjo/Daiginjo
An even more painstaking, labor-intensive brewing process than Ginjo, which results in sake that is even lighter and more fragrant and fruity than a typical Ginjo. Daiginjo often goes as far as a 35% seimaibuai (65% of the rice polished away). Junmai means "pure rice", so no distilled alcohol was added to the sake during the brewing process.*Junmai Ginjo/Ginjo
Indicates a special and painstaking brewing process where
fermentation proceeds at lower temperatures and for longer periods, and
pressing is often done by hand. This extra effort produces a sake that
is layered and complex, light, and fragrant.
All Ginjo and Daiginjo sake are considered "super premium sake". Less than 6% of all Japanese sake falls into this category.
Junmai/Honjozo
Until recently, the minimum milling rate for Junmai was 70%, but the
law changed and now no minimum milling rate exists for Junmai sake.
Unlike for other sake grades, the milling rate must appear on the
bottle.
Honjozo sake is often a bit lighter than Junmai sake, due to the small amount of alcohol added at the end of fermentation.
Futsu
(“Table Sake”)
Made with regular table rice, often using automated brewing processes,
and plenty of distilled alcohol. Futsu represents about 75% of the
entire sake market with premium sake (those sake above this level)
constituting the remaining 25%. Adapted from John Gauntner, Copyright 2002.
*Pure distilled alcohol is sometimes added to premium sake as a brewing technique to enhance fragrance and aromas. In non-premium sake, distilled alcohol is used to reduce the cost of production.
