X.O (700 ml)

Founded in 1715 by Jean Martell, the house made one deliberate break from every rival: distilling exclusively from fully clarified, lees-free Ugni Blanc wine — a choice that strips the raw distillate of texture and pushes all character-building into the barrel.

The result is a cognac whose personality is almost entirely an argument about oak and terroir rather than fermentation. That terroir is the Borderies, the smallest of Cognac's six crus, where silica-clay soils on the gentle hills north of the Charente River yield eaux-de-vie of distinctive floral lift and candied-fruit density unavailable from the chalky Grande Champagne soils favoured by rival houses.

Martell purchases 50–60% of the entire Borderies cru's output, a market dominance with no parallel in the appellation. Distillation runs in traditional copper alambic Charentais stills at the Gallienne Distillery — the largest première chauffe stills in Cognac at ~130 hl — with gas pressure adjusted hourly along the proprietary 'Martell Curve' and tails cut early for a clean, neutral heart.

Aging proceeds exclusively in fine-grained cecillus (Tronçais-style) French oak, lightly toasted (minimum 17–20 minutes bousinage), cycling between new barrels for spice and older 'red' barrels for fruit-forward development; once peak maturity is reached, eaux-de-vie transfer to glass demijohns to arrest further evolution.

The XO draws on components aged well beyond the legal minimum, bottled at 40% ABV. Violet florality, dried apricot, and walnut praline are the Borderies signatures here; the drinking window is open now and holds comfortably for a decade in a sealed bottle.
