Cos is in Saint Estèphe but borders Pauillac and, in particular, the vineyards of Château Lafite. Quality was good in the 1990s but, since the 2001 vintage, it has reached another level. In some vintages the quality level is not far from that of the first growths. The stunning winery is one of the most modern and sophisticated in all of Bordeaux, with a 100% gravity cellar.
Jane Anson describes the wine, 'You need to take a little time to let the concentrated flavours seep out, this is a long hauler. The tannins build slowly but surely through the palate, sombre and serious right now, particularly for an estate that is known for its exuberance. The opulence is there if you give it time, and as the tannins elongate and relax, richer notes of bilberry fruits, toasted cedar, salted chocolate, turmeric and black pepper spice arrives. Harvest September 10 to 24. A 3.9pH is the highest since 2003, but any threat of low acidity is balanced by high tannins, and relatively low alcohol' 97/100
