Pierre Vallet is the great-grandfather of Laurent Vallet, the sixth generation Vallet and the owners of Montifaud. On their Chateau they do everything themselves; grow the grapes, make wine and distill in their traditional Alambic Charentais. The Eau de Vie is matured in barrels of French Limousin oak and bottled in-house. Pierre Vallet differs from its own Montifaud Cognac, because with this Cognac also grapes from the grande Champagne are used. This XO is at least 24 years old.
