One of the “biggest” Cos wines in recent memory, Parker lost his cool for this beauty, loving its “beautifully pure notes of creme de cassis, blueberry liqueur, pen ink, graphite and hints of toast and vanillin.” Vinous said “The palate is medium-bodied with a huge chassis; a Saint-Estèphe clearly built for the long-term with enormous grip and enthralling tension.” Look at this critical consensus!
Situated between Pauillac and Saint-Estèphe, and separated from Château Lafite by the stream known as La Jalle du Breuil (The Breuil Brook), the hill of Cos rises dominates the Gironde from the height of almost 65 feet. Certainly impressive to lay eyes on, and it's exactly what sets the wine apart as well - both in the bottle and on the label. In the old Gascon language, the word "Cos" means "The Hill of Pebbles." And as a matter of fact, the hill of Cos, which is situated on the banks of the Gironde, is an impressive accumulation of Quaternary gravel wrested from the distant mountains of the Massif Central and the Pyrenees and laid on Saint-Estèphe's limestone bed when the primeval river receded. These well-draining slopes formed by erosion have deep layers of gravel - making it not only a geological curiosity, but one of the most precious terroir in the world. Vines can root deeply into these arid soils looking for moisture. As a result the vines work hard and end up producing an intensely flavored and one-of-a-kind wine.
The 2010 is a more structured, restrained, less flamboyant version of the 2009. A final blend of 78% Cabernet Sauvignon, 19% Merlot and the rest Cabernet Franc and Petit Verdot that hit 14.5% natural alcohol, this wine (which represents only 55% of the estate's production) is full-bodied, classic and built along the lines of the 2000 (although that wine was made before Reybier acquired the estate and upgraded quality significantly). This wine exhibits beautifully pure notes of creme de cassis, blueberry liqueur, pen ink, graphite and hints of toast and vanillin. The wine is full and rich, and although aged in 80% new oak, the wood is a subtle background component. This beauty will take longer to round into shape than the dramatic and compelling 2009. Forget it for 5-8 years, and drink it over the following three-plus decades
