94 Points Robert Parker
Composed of 65% Cabernet Sauvignon, 30% Merlot and 5% Cabernet Franc, the deep garnet-purple colored 2011 Cos d'Estournel gives up compelling notes of roasted nuts, black cherry compote, blueberry pie and red and black currants with touches of yeast extract and smoked meats. Medium to full-bodied, very firm, grainy textured and with a great core of youthful black fruits, the palate reveals loads of savory layers on the very long finish. This is very youthful and slowly maturing—a very impressive showing for this vintage!
