Underground Spirits' multi award-winning Signature Vodka has been precisely crafted. High quality wheat grain is the spirit, locally sourced, sustainably grown. Distillation sets up the spirit for 10 times carbon filtration, then they commence their unique cryofiltration process. Extreme low temperatures combined with nano materials enable extraction of impurities never before imaginable. The result is a premium vodka of unsurpassed purity and clarity.
