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! - Lisa Perrotti-Brown

(99+ points) The 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. - Lisa Perrotti-Brown

Stands head and shoulders above the 2009 at this point, here you get the creaminess and power of a great vintage, with tannins that head towards monster-territory, and yet there is real delicacy and hidden complexity here, gorgeous quality, brilliant stuff, exoistc, incense , cinnamon; 100% new oak.

The 2010 Château Cos D'Estournel is based on 78% Cabernet Sauvignon, 19% Merlot, 2% Cabernet Franc and the rest Petit Verdot that was pulled from just 55% of the total production and aged in 80% new French oak. Hitting 14.5% natural alcohol, this still dense purple-hued beauty offers extraordinary notes of blackcurrants, unsmoked tobacco, graphite, freshly sharpened pencils, and chocolate. Full-bodied, massively concentrated, and flawlessly balanced on the palate, it has building tannins, a skyscraper-like mouthfeel that opens up with time in the glass, and a great, great finish. Made in a much more focused, precise, and structured style compared to the more flamboyant 2009, it needs another 7-8 years of bottle age and will be a 50, 60, if not 75+ year wine.

Still young, but even at this early stage, it is impossible not to be wowed by this wine. The layers of depth, intensity, richness, power, and finesse are almost off the charts. The black fruits are perfectly ripe, opulent, flamboyant, and fresh, as well as balanced, pure, and refined. This is a great vintage for Cos that will start showing its best with a few more years of age. Drink from 2028-2060.

A 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. - JM

Darkly fragranced, with chocolate, blackcurrants and violets, ripe fruit and soft woody touches. Tense and compact, tannins with a lovely texture. Nice weight and balance. Silky and streamlined, polished and poised. Long, clean finish with a salty liquorice, tobacco mineral touch. Great structure, weight and definition.

This 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. — Roger Voss
