Courvoisier XO 70cl Is intensely aromatic and flavourful, with a velvety texture and aromatic bouquet, laced with hints of crème brûlée, candied orange and iris flowers. Crème Brûlée: The careful hand toasting of our barrels lends notes of vanilla and caramel that mature to evoke a warm crème brûlée aroma. Candied Orange: Delicate ageing in oak produces this sweet aroma that originates from the Grande Champagne crus. Iris Flower: The sweet and powerful bouquet of irises comes from matured Borderies cognac.
