Vino Generoso Chateau de Leberon Vin Muté a l'Armagnac 19647 €26.36 A vin muté a l'Armagnac is the result of adding Armagnac to the freshly pressed fruit must. In this way, fermentation is not possible, and a product is obtained that is both fruity and spirited. In the case at hand, the Chateau de Leberon uses Colombard grape must, and the result is aged in barrels in a solera that began in 1987. Add to cart
