Sake Classifications are important to understand. They influence both the taste and price of the sake. This chart below outlines the major classifications of sake which are based on ingredients and rice milling rate:
Below are the basic classification grades of Sake:
Junmai:

Honjozo:
Honjozo Sake must be milled to 70% or less of it’s original size and as far as ingredients go, it contains a small amount of distilled brewer’s alcohol, which is added to the sake to achieve different flavor & aroma profiles.
Junmai Ginjo / Ginjo:
