Cos d'Estournel

History of Château Cos d'Estournel

The history of Château Cos d'Estournel began in 1791, when Louis-Gaspard d'Estournel inherited a 14-hectare vineyard situated on the hill of Cos, within the Saint-Estèphe appellation. A visionary, Louis-Gaspard saw immense potential in this terroir. With an audacity that defied the conventions of his era, he gradually expanded the estate, acquiring the finest plots and not hesitating to bypass traditional négociant networks to ship his wines himself to distant destinations, notably India. This pioneering trade earned him the nickname "Maharajah of Saint-Estèphe". 

True to his spirit of innovation, Louis-Gaspard drew inspiration from his travels to conceive the singular architecture of the château, with its famous Oriental-influenced pagodas that still tower over the cellars today. Although he died before seeing his wine officially classified, his pursuit of excellence was crowned in 1855, when Château Cos d'Estournel was recognised as a Second Grand Cru Classé in the celebrated classification of the wines of the Médoc. Since 2000, under the ownership of Michel Reybier, the estate has continuously modernised its facilities while preserving the legacy of its founder. 

Robert Parker awarded a perfect score of 100/100 to the 2009 and 2016 vintages of Château Cos d'Estournel, wines of exceptional quality.

Terroirs and Vines of Château Cos d'Estournel

Château Cos d'Estournel benefits from an exceptionally varied terroir, located in the commune of Saint-Estèphe, at the heart of the Médoc. The name "Cos", meaning "hill of pebbles" in old Gascon, perfectly reflects the unique geology of this vineyard. Spanning 100 hectares, the estate rests primarily on deep gravel soils, ideal for growing Cabernet Sauvignon and Merlot.

The vineyard is divided into a multitude of plots, each cultivated according to its exposure and soil composition. This extremely precise plot-by-plot management allows the full complexity and richness of the Cos d'Estournel terroir to be expressed. Planted with 60% Cabernet Sauvignon and 40% Merlot, along with a few rows of Petit Verdot and Cabernet Franc, the estate's vines are predominantly 45 years old, with some exceeding 80 years. These old vines lend an unparalleled depth and structure to the wines, perfectly reflecting the complexity of the soils from which they draw their essence.

The maritime climate of Saint-Estèphe, shaped by the proximity of the Gironde estuary and the Atlantic Ocean, on the left bank, tempers meteorological extremes, encouraging the slow ripening of the grapes. This preserves the aromatic freshness of the fruit while developing great complexity.

Vinification at Château Cos d'Estournel

Vinification at Château Cos d'Estournel is a rigorously orchestrated art, combining traditional techniques with modern innovations. Since 2008, the estate has adopted an entirely gravity-fed approach, a first in the Bordeaux region. This method allows the grapes and juices to be handled with the utmost gentleness, avoiding the use of pumps. Every movement of the grape, from sorting to bottling, is carried out by gravity alone, thereby preserving the integrity of the fruit and the finesse of the tannins.

The harvest is done by hand, with bunches carefully picked and placed in small crates to prevent any deterioration. The rigorous sorting that follows ensures that only the finest grapes are selected, contributing to the exceptional quality of the cuvées. Vinification takes place in temperature-controlled stainless steel vats of varying sizes to respect the diversity of the plots. The wines are aged in French oak barrels, 80% of which are new, for 18 to 24 months depending on the vintage.

The Cuvées of Château Cos d'Estournel

Château Cos d'Estournel offers several cuvées that reflect the full richness and diversity of its terroir. The fine wine de Cos d'Estournel, the estate's flagship cuvée, stands out for its power and elegance. Crafted primarily from Cabernet Sauvignon, it displays great depth, complex aromas of dark fruits, spices, and cedar, as well as an impressive ageing potential.

La Pagodes de Cos is the estate's second wine, produced with the same care as the fine wine, but made from the estate's younger vines. This wine is more approachable in its youth, with a suppler texture and a more immediately expressive fruit character.

For lovers of white wines, the estate also produces Cos d'Estournel Blanc and Pagodes de Cos Blanc, elegant and refreshing wines with aromas of citrus and white fruits. 

Le Goulée by Cos d'Estournel is another interesting cuvée, produced from vines located further north in the Médoc. This wine stands out for its freshness and vivacity, while maintaining a fine tannic structure.

Finally, the estate also offers the cuvée COS100, a limited edition composed exclusively of Merlot, harvested in 2015. Only 100 double magnums and 10 Balthazars were produced, offering a unique experience to the rare few fortunate enough to taste it.

The wines of Saint-Estèphe, a prestigious appellation of the Bordeaux vineyard, are distinguished by their elegance and longevity. Among the finest vintages are the years 1975, 1982, 1985, 1986, 1989, and 1990, which have impressed enthusiasts with their power and complexity. The following decades were equally remarkable, with exceptional vintages such as 1995, 1996, 2000, 2003, 2005, 2008, 2009, 2010, 2012, and more recently 2014, 2015, 2016, 2017, 2018, 2019, and 2020. These years have confirmed Saint-Estèphe's ability to produce wines combining finesse and depth, emblematic of the Bordeaux terroir.

The Deuxièmes Crus Classés of 1855 represent a prestigious category, bringing together iconic estates that frequently rival the premiers crus in quality. Among them, discover Château Brane-Cantenac and Château Durfort-Vivens, both located in Margaux, as well as Château Lascombes, Château Rauzan-Ségla, and Château Rauzan-Gassies. In Saint-Julien, enthusiasts will appreciate the wines of Château Ducru-Beaucaillou, Château Léoville Las Cases, Château Gruaud Larose, and the celebrated Château Léoville Poyferré and Château Léoville Barton. Do not miss Château Cos d'Estournel and Château Montrose in Saint-Estèphe, as well as the essential Château Pichon Longueville Baron and Château Pichon Longueville Comtesse de Lalande in Pauillac.
