What is Premium Table Rice Sake?
Sake is usually brewed from rice bred for the purpose. Table rice is stickier and higher in protein, so it has long been considered hard to brew. TSUNAN SAKE BREWERY uses 100% Uonuma Koshihikari, a benchmark Japanese table rice, and combines traditional craft with "Smart Brewing," which uses generative AI.

Why table rice
Specialized sake rice can be hard to secure when growing conditions tighten. Choosing Uonuma Koshihikari lets the brewery keep brewing alongside local rice farmers and lighten their burden. Quality, and a sustainable path shared with the region, are treated as one goal.
