Château Cos d'Estournel is a winery in the Saint-Estèphe appellation of the Bordeaux region of France. It is also the name of the red wine produced by this property. The wine produced here was classified as one of fifteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855.
Château Cos d'Estournel produces the eponymous grand vin, the second wine since the 1994 vintage, Les Pagodes de Cos from the estate's younger vines, as well as Château Marbuzet from fruit of nearby plots. The property is adjacent to Château Lafite-Rothschild in the neighbouring commune of Pauillac.
In 1811, Louis Gaspard d'Estournel decided to make wine from a few hectares of vines that he had inherited and Château Cos d'Estournel was born. Classified as a Deuxième Cru Classè in 1855, exports of this prestigious wine eventually reached as far as Southeast Asia, which inspired long-time Sinophile Louis to erect the unique and recognisable stone pagodas which still stand over the estate's cellars. Unfortunately, due to surmounting debts, Louis Gaspard eventually had to sell Chateau Cos Destournel, but his name has endured to this day.
During subsequent decades the estate underwent several ownership changes. However, the most significant improvements to the property were made during the tenure of Bruno Prats, who headed the estate from the late 1980's through to 1998. Along with his son (and current estate manager) Jean-Guillaume, Bruno modernised and improved both the facilities and winemaking practices.
In the old Gascon language of the region, Cos means 'hill of pebbles' and this accurately describes the soil composition of the estate's vineyards - deep gravel over a limestone bed.
The vineyards at Chateua Cos D'Estournel are worked manually and the harvest is always done by hand. Only vines that are more than 20 years old are used for the Grand Vin, while vines which are younger are used for the estate's second wine - Les Pagodes de Cos.
The château cellars were refurbished in 2009 and are now some of the most modern in Bordeaux - a feat of beautiful glass and steel engineering. Fermentation takes place in stainless steel, temperature controlled tanks and both pump-overs and racking are done by gravity. Malolactic fermentation takes place in barrel, of which 60 to 100% are new French oak. Chateau Cos D'Estorunel Grand Vin is aged for 18 months in barrel before bottling, while Les Pagodes de Cos is aged for 12 months.

Tasted at the château, the 1996 Cos d'Estournel was aged in 65% new oak (unlike the 1995 which was 100%) and is a blend of 65% Cabernet Sauvignon and 35% Merlot. It has a straight down the line, intense and focused, graphite and melted tar bouquet. It is almost Pauillac in style, no surprise given its proximity. The palate is medium-bodied with fresh acidity, finer tannin than the 1986 Cos d'Estournel tasted alongside, but sharing those same leitmotifs of black pepper and sea salt. I like the nonchalance of this Cos d'Estournel. At 20 years it is not an ostentatious wine, not determined to go out and impress, but its nuance, stylishness and classicism grow on you. Its virtues seem to register only after you swallow the wine and find yourself tempted back for more. Excellent. Tasted July 2016.

Lots of tobacco, berry and spice character on the nose. Light herbal undertone. Full-bodied, with fine tannins and a caressing, pretty-textured finish. Chewy. I would wait a little. 1995 looks better to me now. Outstanding but not as exciting as I remember.--'95/'96 Bordeaux retrospective. Best after 2008. 26,000 cases made.

Deep ruby-red. Profound, soil-specific aromas of cassis, redcurrant, graphite and pepper, along with a floral perfume. Penetrating, juicy and very intensely flavored, with terrific backbone and density. Really builds in the mouth. The palate-staining finish features tongue-coating tannins and sappy black cherry flavor. This wine features above-average pH for Cos, but the acidity comes across as firm and fresh.
