Mantensei is made at one of the few breweries that produces only Junmai, Junmai Ginjo and Junmai Daiginjo sake. The President, Mr. Masahiko Touda, is also the Toji or Master Brewer, a rare dual role in today’s Japanese sake industry. The brewery has the distinction of being located in Japan’s least populated prefecture (Tottori) where there is an abundance of natural elements available to the small number of breweries located there. The water is extremely soft which allows long, low temperature fermentation which results in a gentle ginjo fragrance and a fresh lively flavor. Suwa brewery also makes their koji at a slightly higher temperature than normal giving their sake a clean and pleasant finish.
