To truly appreciate an XO Cognac, the vessel matters. Pour a small measure into a tulip-shaped glass, which concentrates the complex aromas toward the nose.
Hold the glass in the palm of your hand for a few minutes. The gentle warmth of your skin will release the deeper, hidden notes of rancio, leather, and dried fruit.
Take a small sip and let it coat your palate. Do not rush the experience; allow the spirit to evolve as it breathes in the glass.
