Extremely dark crimson. Lovely spice and breadth. Hint of tobacco leaf with lots of ripe fruit. Very comfortable. A lovely pair of slippers. Real tension and ripeness - great combo. Nothing forced. Ethereal and builds towards the end. Certainly has the graphite ingredient. 13.4% Drink 2024-2040

The 2015 Cos d'Estournel is a blend of 75% Cabernet Sauvignon, 23.5% Merlot and 1.5% Cabernet Franc that was picked between 17 September and 5 October at 44 hl/ha. It is being matured in 65% new oak, less than in recent years due to the tannin (IPT is 71). Deeper in color than the 2015 Pagodes, it has a very pure bouquet with tightly knitted blackberry, blueberry and violet scents, perhaps just a little Margaux-like in style. The palate is medium-bodied with supple tannin, well-judged acidity and harmonious in the mouth. What it does not quite deliver is the complexity of a top-tier Cos d'Estournel or the peacock's tail of flavors on the finish, which feels linear and conservative compared to its peers in more southerly appellations. You feel as if the vintage put a tight leash on this Saint Estèphe grandee. There is pedigree in this Grand Vin for sure and it is bound to give up to 20 years of pleasure.

This shows what great selection did in the northern Mêdoc. Big surprise. Really excellent. Full body, chewy and rich tannins and loads of ripe fruit. Black currants, blueberries. It has hot and ripe tannins yet cool fruit.

Wine Enthusiast - "Ripe, dusty tannins give a dry edge to the full, rich fruits. It has a structure that comes out of old Cabernet vines that form the core of this wine. Dark, full and with considerable concentration, the wine is dense and will need many years to develop.

Château Cos d'Estournel is a Grand Cru vineyard located in St. Estephe. Its oriental facade is adorned with three pagoda turrets, all cast in a soft golden sandstone. Château Cos d'Estournel today covers 170 acres separated from Château Lafite, along the southern edge, by the stream between St. Estephe and Pauillac. The gravelly soil, over a flint, limestone and silicate subsoil low in nitrogen, has eroded over centuries to form steep ridges which perfectly drain the vineyards. The vineyards are planted 60 percent in Cabernet Sauvignon vines, 2 percent of Cabernet Franc, and 38 percent in Merlot.
Wine from St-Estèphe typically matures more slowly than its southern counterparts. The soil is heavy and rich with clay, leading to wines with firm, muscular tannins and high acidity. Dark and opaque in color, the wines can be a bit austere in their youth, though most get softer as they age.
