Bo is the premium craft brand launched in 2012 by Tonoike Shuzo in Mashiko, Tochigi, conceived as a challenge toward the future of sake as both a sensory and cultural experience, with the name carrying the Italian meaning of buono (delicious). All expressions in the Bo range are unfiltered junmai made without added alcohol at 16% ABV, emphasizing clean acidity and umami balance suited to dining, with the line earning recognition at Sake Competition and the Wine Glass Delicious Sake Award.
