Cognac is double-distilled in Charentais copper pot stills from wine grown in the Charente AOC-mandated since the 19th century. Six crus define the region from centre to periphery, with Grande Champagne and Petite Champagne the most prized for their deep chalk soils and exceptional ageing capacity, the Borderies the smallest and most aromatic, and the Fins Bois and Bons Bois covering the balance of production volume. The four major commercial houses Hennessy, Remy Martin, Martell, Courvoisier represent the category to most buyers. Bouchon stocks none of them.

The Bouchon cognac range is built around independent estates and selection houses. Grosperrin is the largest in the catalogue a Paris-based specialist in rare and vintage cognacs sourced from across all six crus, including pre-war vintages with over 50 expressions across the range. Paul Giraud is a family estate in Grande Champagne producing from their own 30-hectare domain. Jean Fillioux is a multi-generation Grande Champagne family house in Jarnac Champagne. Normandin-Mercier, based in Saint-Jean-d'Angely, is one of the few remaining independent merchants sourcing across the crus. Francois Voyer and Dudognon round out the range with estate and single-cru expressions.
