Cognac is rarely born of a single eau-de-vie or a single growing area, but generally from a blend of different ages and crus, sometimes up to a hundred of them.
It can be made also exclusively from certain “cru”, for example exclusively from “Grande Champagne”, but of different ages.
Grande Champagne : about 13,000 hectares of clay and compact chalk soil. The Grande Champagne cru is located around the town of Segonzac. It produces a very fine, high-quality Cognac. It is known as the Premier Cru du Cognac.
