The exceptional 2006 Cos d’Estournel is composed of 78% Cabernet Sauvignon, 20% Merlot, and 2% Petit Verdot, 55% of the production was utilized. Revealing superb intensity for a 2006 as well as an inky/blue/purple color, and a sweet bouquet of blue and black fruits, licorice, graphite, and charcoal, this full-bodied 2006 possesses high levels of sweet tannin. This wine is characterized by a freshness and precision that give it a 1996-like affinity. Enjoy this beautifully concentrated, exceptionally pure, statuesque Cos d’Estournel over the next 20-25 years. By the way, it was bottled without any fining or filtration. - WA, RP (2/2009)

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.—Non-blind Cos-d'Estournel vertical (December 2015). Drink now through 2026. 15,800 cases made, 1,600 cases imported. — JM (03/2016)

Good deep ruby-red. Expressive aromas of dark raspberry, smoked meat, black olive, iron, smoke and tobacco. Lush, broad and sweet, with a deep smoky, meaty sweetness and outstanding palate coverage. For all its breadth and silkiness, there's no shortage of energy and definition. Finishes impressively long, with chewy, sweet tannins that dust the front teeth.- Stephen Tanzer (5/29)
