Crystal Head Vodka is a brand of vodkas manufactured by Globefill Inc. in Newfoundland and Labrador, Canada. It was conceived and founded by actor Dan Aykroyd and artist John Alexander in 2007.
The blends are quadruple-distilled and seven times filtered, with the final 3 filtrations through Herkimer diamond crystals, which are actually a type of double-terminated quartz rather than diamond.[1] The vodkas are produced without the addition of glycerol, citrus oils or sugar.
The Crystal Skull bottle was designed by John Alexander[2] and is manufactured by Milan-based glass-manufacturer Bruni Glass.[3][4]
