Château Cos d’Estournel can be found in the Saint-Estèphe appellation of the Bordeaux region of France and boasts one of the fifteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855. Cos d’Estournel is adjacent to Château Lafite-Rothschild in the neighboring commune of Pauillac and is an ideal wine for investment.

Château Cos d’Estournel has changed hands several times in its illustrious history. English banker Charles Cecil Martyns purchased the land in 1852, only to sell the estate a few years later to the Spanish Errazu family in 1969. Just 20 years later, the Errazu family relinquished the estate to the Bordeaux-based Hostein family. 


Château Montrose owner Louis-Victor Charmolüe married into the Hostein family and gained control of Château Cos d’Estournel in 1894. Finally, in 1917, the estate was sold to Fernand Ginestet. 


The château has been in the Ginestet family since the 1917 purchase. In !970, the estate joined the Domaines Prats, the combined holdings of the Ginestet and Prats families and controlled by Bruno Prats. 


Cos d’Estournel is situated in the heart of the northern Médoc; “cos” is derived from the word for “hill of pebbles” in the old Gascon dialect. The estate classified the vineyard as a “near miracle in geographic and geologic terms” due to the deep gravel plateaus and gravel and clay-rich downward sloping hills.

The mastery of the estate’s unique geology allows different wines to thrive in various soils. The Merlot is grown in the east on clay-limestone soils, while the  Cabernet Sauvignon is grown on the highest parts of the plateau where it can properly drain. The vineyard’s physical location enables the growth of unique and complex wines. 


Saint-Estèphe is found between the Gironde Estuary and the Atlantic Ocean. The oceanic climate mitigates extreme temperature fluctuations and weather conditions, sanctioning a gentle ripening of the grapes. The ocean wind blowing through the vineyards is known to dry the excess humidity so the grapes can ripen on the vine in an idyllic environment. 


The vineyard itself is a sprawling 170 acres divided into 30 parcels. The estate produces 60% Cabernet Sauvignon and 40% Merlot, with minor cultivation of Cabernet Franc and Petit verdot. Typically, Cos d’Estournel produces around 32,000 cases annually. 


Cos d’Estournel produces the grand vin, the second wine since the 1994 vintage, Les Pagodes de Cos, from the estate’s younger wines, and finally the Château Marbuzet.
