"Tanqueray Sterling vodka is made from pure grain spirit, distilled at high proof and carefully distilled a second time in a 220-year-old copper pot still. After the final distillation, the spirit is ""cut"" with water to give it the final desired 80 or 100 proof (40% or 50% alcohol). Tanqueray Sterling vodka carries on the tradition of expertise, taste, status and unsurpassed quality already associated with the Tanqueray name, all of which combine to create the smooth, balanced body that one would expect from a premium quality vodka."
