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.

A word of admiration and praise is in order for Bruno Prats. One of St.-Estephe's most forward thinking producers, Prats is never content with merely making outstanding wine. Over the last few years he has improved Cos d'Estournel, already one of the great wines of Bordeaux, by eliminating any filtration at bottling, and replacing the standard paper label with one made of plastic so it will not disintegrate in damp, humid cellars. Additionally, the quality of his wines in such difficult vintages as 1992 and 1993 has been remarkable. Readers should also note that a second wine, the beautifully packaged Les Pagodes de Cos, has been implemented with the 1994 vintage. It appears to be a fine second wine. While tasting through Cos d'Estournel's wines, it was interesting to taste the unfiltered 1994 against the same cuvee of wine that was put through the normal filtration. The filtered cuvee was an excellent wine (I rated it 88), but as Bruno Prats and several other people at the tasting could easily see, it had less opacity, color, and aromatic interest, and far less volume and mid-palate. Most Bordeaux chateaux continue to do too much fining and filtering, but some of the more seriously run estates are curtailing the most abusive clarification procedures, and are finally opening their minds to the negative impact too much fining and filtration can cause. Sadly, most of my colleagues have fallen hook, line, and sinker for the standard response from oenologists and producers on this issue ... "fining and filtration have no effect on a wine."
Cos d'Estournel's unfiltered 1994 is one of the top wines of the vintage. It boasts an opaque blue/black/purple color, as well as a fabulously sweet nose of black fruits, licorice, pain grillee, and Asian spices. Full-bodied, with sweet, opulent fruit that reveals none of the vintage's tough tannin, this remarkably rich, well-balanced, classic wine will prove to be uncommonly long-lived. Anticipated maturity: 2003-2025. Cos d'Estournel is clearly producing wines that are often of first-growth potential.

Outstanding quality for the vintage. A full-bodied Bordeaux that offers wonderful aromas of tobacco, berry and cedar, loads of refined tannins and a long, flavorful finish.

Gingery sweet oak, black raspberry, black cherry and spice on the nose. Dense and firm, with very good concentration. Expressive and enticing thanks to the very ripe merlot (for the half of the crop that did not go through reverse osmosis, the merlot was chaptalized just a half degree, vs. two for the cabernet sauvignon). Deep and long, with enough acidity to give the wine excellent balance.
