Crystal Head Vodka is manufactured by Globefill Incorporated at the Rock Spirits distillery of Newfoundland and Labrador Liquor Corporation, located in Newfoundland, Canada.
Ontario sweet corn, grown in the Chatham-Kent region of Ontario, is processed and distilled four times, unaged, to produce a neutral grain spirit with 95% alcohol by volume. The raw spirit is subsequently reduced with Newfoundland water until reaching 40% alcohol by volume. The liquid is filtered seven times, and the last three through Herkimer diamond crystals, which are a type of double-terminated quartz rather than diamond.
