This blend includes eaux-de-vie from Martell's four main terroirs, but is marked by a subtle balance between the elegance and roundness of the old Borderies eaux-de-vie and the structure of those from Grande Champagne. XO stands of Extra Old, and denotes cognacs made from old eaux-de-vie. The decanter has a strong, architectural quality. The arch-shaped base is emblematic of Martell: a solid foundation reflecting the strength and determination of the House. The contrasting slender shape of the silver cork lifts the decanter with a touch of elegance, giving it a remarkable aesthetic balance.
