Produced at the legendary Tsutsumi Shuzo, which has been producing shochu in the Kumamoto Prefecture in Kyushu, Japan, for nearly 150 years, Oka Kura Bermutto is an aromatized Junmai sake fortified with shochu. Bermutto, a Japanese phonetic spelling of vermouth, is a uniquely Japanese interpretation of the classic fortified wine. Bermutto uses yomogi, a Japanese mugwort, as its primary bittering agent, in addition to the Japanese citrus fruits yuzu and kabosu, and sansho peppercorn, a citrusy peppercorn which produces a mouth-numbing effect. Use as a substitute for traditional dry vermouth to add new depth to cocktails.
