Wine Advocate-Parker :
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. The full-bodied palate is built like a brick house with a solid frame of super firm, super ripe tannins and seamless freshness to back up the vibrant, crunchy, oh-so-muscular fruit, finishing long with loads of mineral layers. Amazing structure will keep this beauty for at least half a century and probably a full one!
