Akita Shuzo was founded in 1908 in Akita City and brews the Suirakuten label, a name that translates loosely as heaven of tipsy delight. The brewery's signature Daiginjo Suirakuten is aged at low temperature in the bottle for up to two years, an uncommon practice for the style that develops a layered, multihued flavor profile beyond what standard daiginjo typically offers. Fermenting slowly over up to 25 days before pressing, the brewery has built a family of clean, balanced sakes that honors Akita's sake-producing heritage through careful, patient craftsmanship.
