Grey Goose is the first vodka to be produced in the Maître de Chai tradition, which allows aromas to be produced in the distillation process specific to Grey Goose vodka. It is made from 100% French ingredients, including flavored versions of vodka. For instance, Grey Goose La Poire was the result of Thibault's relationship with a Parisian pastry chef, whose pear Tarte inspired the recipe for the new vodka flavor.
