Oka Japanese VodkaPot distilled from Japanese rice in Kumamoto (the rice basket of Kyushu), OKA VODKA is an elegant spirit crafted and proofed for contemporary cocktailing. Clean and crisp with elegant, floral aromas that harken to Tsutsumi Distillerys sake and shochu production lineage, OKA VODKA is filtered using bincho tan, an artisanal Japanese charcoal measured as the purest carbon charcoal in the world with a carbon purity of 98. 8%!
