Muscat Bailey A grapes from Yamanashi Prefecture are fermented in a historic stone cellar. This limited-edition wine is crafted in the Ishigura fermentation tank, a national cultural treasure and a piece of Japanese heritage.

Built in 1901 from granite, the Ishigura fermentation tank uses geothermal energy to maintain stable fermentation temperatures. This traditional method, essential before modern temperature control, ensures high-quality fermentation and exceptional wine.
