Yamagata Masamune山形正宗 · Mitobe Shuzo 水戸部酒造
Mitobe Shuzo brews with unusually hard water drawn from the Gassan river system, giving Yamagata Masamune a sharp, blade-like dry edge rare among Yamagata’s typically softer sakes. The brewery has taken ‘sake starts in the rice paddy’ literally, farming much of its own rice since the 2000s, and moved its entire lineup to junmai-only production in 2010.
