Xo

XO, meaning "Extra Old," is an age designation used primarily for Cognac and Armagnac, indicating extended aging in oak barrels. Under French regulations, XO Cognacs must age for a minimum of ten years, though many producers age their XO blends significantly longer. The designation represents the oldest category in the official Cognac age classification system, above VS and VSOP. In Armagnac, XO indicates a minimum of ten years aging, while other spirits like rum may use the term without strict regulatory oversight.

XO spirits typically display deep amber to mahogany colors developed through prolonged wood contact. The extended aging creates complex flavor profiles characterized by dried fruits, nuts, leather, tobacco, and warm spices. Cognacs at this level often show notes of figs, dates, and honey, balanced by oak-derived vanilla and tannins. The alcohol integration becomes remarkably smooth, with layers of flavor that evolve in the glass. Armagnac XO expressions tend to be more rustic and intense compared to their Cognac counterparts, while aged rums bearing the XO designation may exhibit tropical fruit and molasses characteristics.

The XO category includes prestigious houses from France's Cognac and Armagnac regions, as well as premium aged rums from traditional rum-producing territories. Major Cognac producers like Hennessy, Rémy Martin, Martell, Courvoisier, and Delamain each offer distinct XO expressions that represent their house styles. Château de Laubade produces XO Armagnac from the Bas-Armagnac appellation, while producers in Martinique create aged agricultural rums that may carry the XO designation.
