In the upper echelon of 2nd Growth estates, Chateau Cos D''Estournel is located in St-Estephe appelltion, on the fringe of Paulliac and notably just north of the famed Lafite vineyards. Tourists flock to the Medoc estate to see the unusual, Asian-inspired Chateau design, but the wines hold their own and rightfully are considered the finest within St-Estephe. Oak is set to around 80% new barrels while alcohol is a modest 14.5%; the blend in 2010 is 78% Cabernet Sauvignon with 19% Merlot and complimentary Cabernet Franc and Petit Verdot in tow. A wine for thirty or so years.

Planted in 1300, the estate is the oldest planted vineyard in the Pessac-Léognan appellation, ranked among the Premiers Crus for red wine in the Classification of Graves wine of 1959.
