99+ Pts Lisa Perrotti-Brown - Robert Parker's Wine Advocate

"Blended of 78% Cabernet Sauvignon, 19% Merlot, 2% Cabernet Franc and 1% Petit Verdot, the 2010 Cos d'Estournel is deep garnet with a touch of purple and comes at you like a variegated scent wall with profound notions of blackcurrant cordial, chocolate-covered cherries, spearmint, cigar box and hoisin plus suggestions of praline, charcoal and espresso. Full-bodied, the palate is jam-packed with layer upon layer of black and red fruits plus tons of savory accents and a firm backbone of ripe, grainy tannins, finishing very, very long, carrying great freshness and a beautiful spearmint lift. It’s a lot like the 2005 but with the volume turned up here. These 2010s are truly locked in a time capsule."

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.

There’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.

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.

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.
