Wall Street Journal Plus Members Exclusive - Crystal Head creators philosophy is that the finest vodka is untouched. Naturally smooth. Crystal Head contains no additives. No glycerol, citrus oils or sugars. Nothing is added to enhance or mask the taste. Highest quality peaches and cream corn is distilled four times into a neutral grain spirit and blended with pristine water from Newfoundland, Canada. The liquid is then filtered seven times, of which three are through layers of semi-precious crystals known as Herkimer diamonds. The larger 1L bottle gives you more vodka.
