"With its aromas of new wood, spice and black fruits, this promises from the start to be a powerful, polished wine. It is dense, very ripe (from the high percentage of Merlot in the blend), but still packed with tannins. It's a massive wine, bringing together the heat of 2003 with the big tannins of Saint-Estephe."
Robert Parker's Wine Advocate (RP): 98
The prodigious, fantastic 2003 Cos d'Estournel is a candidate for 'wine of the vintage.' A blend of 68% Cabernet Sauvignon (unusually high for this chateau), 30% Merlot, and 2% Cabernet Franc, 17,500 cases were produced from low yields. "An inky/blue/purple color is accompanied by a compelling perfume of black fruits, subtle smoke, pain grille, incense, and flowers. With extraordinary richness, full body, and remarkable freshness, elegance, and persistence, this is one of the finest wines ever made by this estate. The good news is that it will be drinkable at a young age yet evolve for three decades or more. Kudos to winemaker Jean-Guillaume Prats and owner Michel Reybier. "

"Red-ruby. Knockout nose combines currant, espresso, earth and exotic spices. Wonderfully round and sweet, with outstanding volume and density. A spherical, seamless wine that saturates the entire palate. The huge but lush tannins coat the teeth. This is accessible now but has the sheer material for long aging."
Wine Spectator (WS): 97
"Gorgeous aromas of blackberry, spice and mineral. Full-bodied, with ultrafine tannins and a long, long finish. This is first-growth quality. Best after 2012"
