The oldest expression for the Marquis de Montesquiou brand, which is now under the stewardship of Monkey 47 Gin founder Alexander Stein. The XO features a remarkable blend of different eaux-de-vie, the youngest of which is at least 10 years old, with some aged up to 50 years, all embodying the savoir-faire of Bas-Armagnac and Ténarèze.
