The Japan Premium Sake Association
Ginjoshu is brewed by eliminating parts that cause zatsumi (unfavorable taste) as much as possible from rice which is the ingredient of sake, and using yeast to create a ginjo aroma and brewing it at colder temperatures for long periods. The brewing style was established in the Meiji Period (1868-1912), however it was at the end of the 1970’s when ginjoshu started being merchandized in the market. Then in 1981, 42 sake breweries which had already been engaged in the brewing of ginjoshu established the Japan Premium Sake Association to start promoting ality Indication for Sake, it was defined that ginjoshu should use rice with a polishing ratio at least 60% or less.
