Established in 1992, SKYY Vodka is the number one premium vodka in the United States and the fifth premium vodka in the world. Through the process of quadruple distillation and triple filtration, SKYY obtains a vodka of proven, exceptional quality and softness. Because this filtration makes for a spirit nearly free of congeners (substances other than alcohol produced during fermentation), a supposed company slogan is "Vodka so filtered, we even took the Russia out of it."
