This premium rice koji is made using heirloom spores—prized for their enzymatic strength and superior umami flavor—from Higuchi Matsunosuke Shoten in Osaka, Japan, and carefully cultivated on certified organic Calrose rice from southern California.

All koji is made by hand at Virginia’s first and only sake brewery -  North American Sake - in Charlottesville, VA.
