The headquarters of Grey Goose Vodka, in Gensac-la-Pallue in the Cognac region, sit right atop the spring of water filtered by layers of limestone used in the bottling process. The entire production is based in this state-of-the-art facility

The region authorised to produce cognac is divided into six zones, including fivecrus broadly covering the department of Charente-Maritime, a large part of the department of Charente and a few areas in Deux-Sèvres and the Dordogne. The six zones are: Grande Champagne, Petite Champagne, Borderies, Fins Bois,Bon Bois and finally Bois Ordinaire. A blend of Grande and Petite Champagne Cognacs, with at least half coming from Grande Champagne, is known as Fine Champagne. Cognac-producing regions should not be confused with the northeastern region of Champagne, a wine region that producessparkling wine by that name, although they do share a common etymology – both being derivations of a French term for chalky soil.
