"The 2006 Cos d’Estournel, for my mind, has always been leagues above its rival, Montrose, principally because its rival took a rare misstep in this vintage. It has an attractive ferrous bouquet with undergrowth and hints of Indian spice. The palate is medium-bodied and quite fleshy for Saint-Estèphe, the Merlot in quite expressive. The texture has a satisfying graininess and that spiciness returns towards the rather conservative, steadfast finish. It is a solid Cos d’Estournel, not one from the very top drawer, but it should provide another 15 years of drinking pleasure. Tasted at the Cos d’Estournel vertical in London." -Vinous
"Blended of 78% Cabernet Sauvignon, 20% Merlot and 2% Petit Verdot, the 2006 Cos d'Estournel is deep garnet colored with a touch of brick, opening with enticing scents of rosemary-crusted roast lamb, dried cherries, baked blackcurrants and mincemeat pie with touches of fallen leaves, cigar box and pencil lead. Medium-bodied, lively and elegantly played in the mouth, it has a firm backbone of chewy tannins and plenty of mineral accents on the long finish." -Robert Parker
"There is still an austerity to this wine, and the firm cassis fruit has a power and push of its own — similar to the 2008 vintage in many ways. The tannins are pulling their weight by deepening the structure and filling out the fruit. They were strict, almost cubic, during the first few years and it is only now that they are starting to come around. This vintage was extremely hot in June, and things got more complicated as harvest approached. Today, the nudging ripeness of the fruit emphasises pepper, mint and eucalyptus — creating a fresh core that might have been tough when young but it’s become a benefit over time. This is a very good and enjoyable wine with plenty to say, with hints of tertiary notes emerging."
"A racy, fresh style, with the lighter profile of the vintage pulling in red currant and bitter cherry flavors, while the telltale thread of charcoal and bay lingers as well. The tannins are ever so slightly grainy, but the fruit has subtle persistence in the end."
"Cos d’Estournel has softened those austere Saint-Estèphe tannins and produced a wine that is all opulence and roundness. The tannins are certainly there, but they come through as big, bold richness. The power suggests it will age well, but for drinking earlier, the freshness of the sweet homemade plum jam promises well."
