The 2018 Cos d'Estournel is composed of 74% Cabernet Sauvignon, 23% Merlot, 2% Petit Verdot and 1% Cabernet Franc and has 14.59% alcohol. Aging in 50% new barriques, it has a deep purple-black color and drifts effortlessly, gracefully, seductively out of the glass with slowly unfurling notions of blackcurrant cordial, wild blueberries, chocolate-covered cherries and plum pudding with touches of violets, licorice, wild roses and yeast extract plus a waft of loose tobacco.
