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.- Neal Martin (04/2016)

This has a gently steeped core of currant, plum and black cherry fruit, infused with black tea, singed juniper and smoldering tobacco notes. The vintage's overt austerity is less evident here, with a gloss of alluring toast adding polish to the finish. A strong effort. Best from 2020 through 2032. 15,000 cases made. — JM (03/2018)
