Deep garnet in color, the 2010 Cos d’Estournel unfurls slowly, measuredly, releasing delicate notes of dried mulberries, stewed plums and blackcurrant pastilles before giving way to notions of potpourri, black cherry compote and chocolate box plus touches of dried sage, tobacco and new leather. Medium to full-bodied, the palate has a rock-solid foundation of very firm, grainy tannins and very lively acidity supporting the remarkable intensity of tightly wound fruit layers, finishing very long and fragrant. Give it another 4-5 years in bottle and this will be stunning!Robert Parker Wine Advocate | 99 RPThe 2010 Cos d’Estournel is a blend of 78% Cabernet Sauvignon, 19% Merlot, 2% Cabernet Franc, and 1% Petit Verdot. Deep garnet colored, it needs a lot of shaking and swirling to unlock notes of crème de cassis, blueberry pie, and Indian spices, leading to fragrant wafts of dusty soil, cigar box, and dried lavender. The palate gracefully grows into a rich, full-bodied behemoth, delivering a rock-solid structure of firm, grainy tannins and bold freshness to support the taut, muscular fruit, finishing long and minerally.The Wine Independent | 99+ TWIThere’s clarity and beauty to this wine as always with pure dark berry, stones and spices. Some clove too. Full body, firm and silky tannins and a long finish. Pure and precise wine with so much class. Try in 2020.James Suckling | 98 JSThe 2010 Cos d’Estournel is initially backward on the nose, yet it eventually unfurls to reveal pixelated black fruit, crushed stone, cedar and pine cones, wonderful precision and focus. The palate is medium-bodied with grippy tannins that frame the multi-layered black fruit laced with cedar and black pepper. Great body, superb length and outstanding precision on the finish - what more would you want? Tasted blind at Farr Vintners 10-Year On Bordeaux horizontal.Vinous Media | 97 VMA great contrast to the ’09, this feels even denser, with dark plum, black currant and fig sauce flavors that pump along. The spine is all graphite and chalk, giving this a riveting feel through the finish. The cut is terrific, no easy feat considering how dense the fruit is. A stunning wine.—Non-blind Cos-d’Estournel vertical (December 2015). Best from 2025 through 2045. 16,000 cases made.Wine Spectator | 97 WS(Château Cos d’Estournel, St-Estèphe, Bordeaux, France, Red) Starting to really open up at this 11 year point, although the tannins remain in full control. Deep rich chocolate, edges of smoked cinnamon, anis, Crème de cassis, cigar box and earth. Plenty of the Cos signature of exotic spices on display, making it a little more exuberant than some 2010s at this point, balanced beautifully by the savoury edge of Cabernet that means it narrows to a fresh and mouthwatering finish. This is young but you can see where it is going, and 1% Petit Verdot completes the blend. (Drink between 2021-2045)Decanter | 95 DECThis is a complex and rich wine dominated by superripe fruit. It is a wine of extremes, of fruit, of dark tannins allied to some bitterness from the black chocolate extract. Ripe plums and sweet black fruits are given a lift at the end with bright acidity.Wine Enthusiast | 95 WE(Château Cos d’Estournel) The 2010 Château Cos d’Estournel is the ripest of the three wines at the estate this year, as it weighs in at a hefty 14.5 percent alcohol, but this is most certainly down significantly from the 2009. On the nose the wine is remarkably pure for its octane level, as it offers up a reasonably complex mélange of black cherries, a touch of kirsch, stony soil tones, fine cigar smoke and a very, very refined base of new oak that is mostly redolent of lead pencil. On the palate the wine is deep, full-bodied and very, very powerful in personality, with stunningly fine balance for such a large scale wine. The mid-palate depth here is absolutely exceptional, and the very firm tannins are seamlessly integrated into the body of the wine. The finish is truly massive, but I find no signs of uncovered alcohol on the backend and the balance here is remarkably suave for such a big-boned wine. Like several other high alcohol 2010s, the ripeness here really is most keenly felt in a loss of focus and precision from the high octane, in addition to a touch of overripe aromatics and flavors. But in comparison to what was an egregiously out of balance 2009 Cos, the 2010 is remarkably more impressive in terms of harnessing its power and crafting a perfectly balanced wine. It must be said that if I were the proprietor at this fabled estate, this is emphatically not the kind of wine I would be making from such a great terroir, but the 2010 Cos d’Estournel is a dramatic step up in quality from the 2009. It is still a very tannic 2010 and will need plenty of cellaring to start to soften, but it should prove to be extremely long-lived as well. I would score it even higher, for to achieve this kind of seamless balance at this alcohol level is no small feat, but there is a slight lack of focus and some notes of sur maturité here that has to result in the deduction of at least a few points.
