Koshi no Kanbai越乃寒梅 · Ishimoto Sake Brewery 石本酒造
In the 1960s, while much of Japan’s sake was being stretched with sugar and added alcohol, Ishimoto Sake Brewery kept making clean, authentic sake the old way. Word of mouth turned Koshi no Kanbai into the original ‘phantom sake’ — a bottle city drinkers couldn’t find — and it effectively started Japan’s whole local-sake boom. The house style hasn’t changed: light, dry and precise, in the tanrei-karakuchi idiom that defines Niigata.
