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.
