Tasting Notes:  Canadian corn vodka that's additive free sold in the skull head bottle and shilled by one of the Ghostbusters??? Yep, that's Crystal Head in a nutshell. "It is distilled four times into a neutral grain spirit and blended with pristine water from Newfoundland, Canada. The vodka is filtered seven times, of which three are through layers of semi-precious crystals known as Herkimer diamonds." Available at Select Stores.
