Kimoto (720 ml)

When 6th-generation owner Yuji Tsuchida inherited the brewery, he made a calculated break from his predecessor's ginjo-focused, heavily polished style — redirecting the entire lineup toward Edo-period kimoto technique and maximum rice expression. That decision defines every bottle of Tsuchida Kimoto.

The brewery sits at the southern foot of Mt. Hotaka in the mountainous northern Gunma highlands, drawing on spring water that has filtered underground for approximately 50 years before reaching the brewery. That mineral-laden, slow-filtered water underpins the sake's structural depth and supports the cool-climate, slow fermentation the kimoto method demands.

Fermentation begins with a fully traditional kimoto shubo, relying entirely on ambient lactic acid bacteria from the brewery air — no manufactured lactic acid added — a practice used by fewer than 1% of Japanese producers. The rice is Asahi no Yume, a Gunma-grown edible table rice polished to just 90% seimaibuai (only 10% of the grain removed), with a koji ratio of 30%. Fermentation runs approximately twice the duration of modern accelerated methods.

The simultaneous use of non-sake rice at 90% polish and full-house kimoto fermentation is practiced by virtually no other brewery at scale — this is the transgression that defines Tsuchida's identity. The result is deeply umami-driven, with pronounced natural acidity and a long savoury finish that rewards the table rather than the tasting glass.
