Château Cos d'Estournel was built at the beginning of the 19th century by Louis Gaspard d'Estournel. Nicknamed the Maharadjah of Saint Estèphe on account of his passion for travel to the Indies, he built exotic pagodas above the winery, in memory of the distant lands he had visited. The property's wine quickly gained a reputation as one of Bordeaux's finest and began to be exported all over the world; in the 1855 classification it was ranked as a second growth. Today, this prestigious vineyard belongs to Michel Reybier and covers 67 hectares. With the Gironde estuary to the east and the Atlantic Ocean to the west, the property benefits from a microclimate with very stable temperatures. In old Gascon, Cos means hill of pebbles, which is certainly justified by the terroir's geological characteristics: an accumulation of gravel from the Quaternary era resulted in the formation of a hill about 20 metres high, on top of which sits the château, looking down over the river. Only grapes from vines that are more than 20 years-old are used to make Cos d'Estournel's grand vin, the rest go into the second wine. Carrying out nearly all tasks manually, the property uses new oak barrels to age the wines, thereby enhancing the flavours with a subtle woodiness. There is then a final selection, which reduces production to between 200,000 and 380,000 bottles.

This is the second wine of the prestigious Cos d'Estournel, and is produced from the property's youngest vines. These grapes were previously used to make Château de Marbuzet. A real second wine has been made at Cos since 1994. The young vines, aged between five and twenty years-old, are cared for in the same way as the older ones. Powerful and highly aromatic, with excellent length, "Les Pagodes de Cos" is a wine of tremendous elegance which can be drunk after ageing for two or three years, thereby enabling you to wait patiently for the grand vin.
