Château du Busca-Maniban distills armagnacs in their oldest distillery in Gascony for over 300 years. These armagnacs are produced using traditional methods and aged in oak barrels in the castle cellars. The region of Ténarèze, known for its clay and limestone soil, is similar to the top growing regions of Grande Champagne in Cognac, where Ugni Blanc grapes dominate. Armagnac from Ténarèze ages for a longer duration and delivers superior quality.
