Frapin is unusual among Cognac houses in being a single-estate producer, working exclusively with its own Grande Champagne vineyards — the most prized of the region's crus, prized for producing eaux-de-vie that age gracefully over decades. VIP XO reflects that: floral and delicate on the attack, then long and warm, with candied fruit and gentle oak. Serve at room temperature in a tulip glass, never warmed over a flame.
