Cognac Chabasse X.O. The growth of the Petite Champagne and Fins Bois provide a perfect harmony. Their specific power and finesse are delicately balanced, the woodiness has softened, and the body has become rounder after the fine, elegant initial taste. The characteristics of vintage port melt into somewhat rounder aromas of dry fruit, such as hazelnut and walnut, following the floral touches of iris and hyacinth which add freshness to this harmonious blend. The Cognac has taken on a darker color, with russet reflections specific to Cognacs that have benefited from the long oxidation in the barrel.
