Tesseron is one of the few remaining houses to use the original three Cognac grape varieties: Ugni Blanc for roundness, Folle Blanche for finesse and Colombard for strength and depth. The grapes are virtually all sourced from the top two Cognac districts: Grande Champagne and Petite Champagne. All of Tesseron’s cognacs are aged exclusively in Limousin oak, a tough wood which has a fatter, looser grain than that of the more common Tronçais oak, thus giving more oxygen and finer tannins, as well as being better adapted to long-term maturation. The house also makes a point of aging all of its cognacs in humid rather than dry cellars, resulting in a more rounded flavor profile.
