I know the Kirkland vodka is made in the same region of France as Grey Goose. With essentially the same materials and with the same distillation process etc. Supposedly they just went out and hired the folks that make Grey Goose or something to that effect and opened their distillery in the same area. So it's Grey Goose quality at Absolut price.
They also get pretty high end scotch licensed from the big folks,
Glenlivetetc, but apparently that shit sells out almost instantly. People find out what kind it will be the next time it comes around and get ready to stock up.
