Bamboo Charcoal Filtration
Part of the unique creation process behind Haku Vodka, the bamboo charcoal filtration is a Suntory proprietary method. Like a sponge, the charcoal absorbs most/many impurities present in the distillate, eliminating things that might detract from the taste. This gives the vodka a clean and clear flavor. Moreover, the minerals from the bamboo charcoal add a remarkably smooth and mellow character.
The use of bamboo charcoal for water filtration is one of the fundamentals of Japanese culture and goes back to ancient Japan where charcoal was said to “sweeten” the water for tea. It is known for its incredible filtering ability, which comes from its super-porous structure. As bamboo is a fast-growing plant, supply is abundant and sustainable in Japan.
