Crystal Head Vodka is perfect as a lone shot, chilled or served in signature cocktails. Unlike most vodkas in today's marketplace that use additives, glycol, citrus and sugar to improve smoothness and flavor, Crystal Head Vodka is a pure spirit with no additives. It is quadruple distilled and filtered three times through charcoal followed by triple filtration over Herkimer crystals from one of the planet's rarest deposits of close concentrated semi-precious stones.
