SKYY vodka is produced by SKYY Spirits LLC in San Francisco, California.  SKYY Vodka is 40% ABV or 80 proof; SKYY 90 Vodka is 90 proof high-priced brand aimed at martini drinkers.  When SKYY Spirits LLC first launched in 1992 SKYY vodka was its first product; its creator, Maurice Kanbar, claims the vodka is nearly congener-free due to its unique distillation process.  The distinctive bottle is a cobalt blue with a plastic label.  In 2008, SKYY expanded the SKYY Vodka line with five new flavours, referred to as SKYY Infusions.
