The history of Château Cos d’Estournel begins in 1811 when its owner Louis Gaspard Lacoste of Maniban Marquis d’Estournel, having inherited some vineyards near the village of Cos, decides to vinify them separately. The wine of Cos d’Estournel was born.
At Château Cos d’Estournel, vinification adapts to the character of the harvest, to favor the expression of the terroir and this thanks to a new cellar. Precise grape sorting and pure gravity pumping using 4 lift vats as well as precise control of fermentation temperatures favor the selection of the softest tannins and the preservation of the fruit. The aging in new oak barrels merrain discretely enhances aromas and flavors with a fair woody. Château Cos d’Estournel will then spend 18 months in barrels.
