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!

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 is a more structured, restrained, less flamboyant version of the 2009. A final blend of 78% Cabernet Sauvignon, 19% Merlot and the rest Cabernet Franc and Petit Verdot that hit 14.5% natural alcohol, this wine (which represents only 55% of the estate's production) is full-bodied, classic and built along the lines of the 2000 (although that wine was made before Reybier acquired the estate and upgraded quality significantly). This wine exhibits beautifully pure notes of creme de cassis, blueberry liqueur, pen ink, graphite and hints of toast and vanillin. The wine is full and rich, and although aged in 80% new oak, the wood is a subtle background component. This beauty will take longer to round into shape than the dramatic and compelling 2009. Forget it for 5-8 years, and drink it over the following three-plus decades.
