Why this vintage

Critic scores

The 2009 vintage in Saint-Estèphe

Vintage benchmark: 98/100 (appellation benchmark, not a score for this wine)

Vintage character: A sun-drenched season from start to finish gave opulent, fleshy wines, immediately appealing yet built for the cellar.

Overall reading of the year’s season across Saint-Estèphe. An estate can depart from it sharply, in frost or hail years, where two neighbours did not make the same vintage. What this particular wine actually gave is on its technical sheet and in the scores above.

Tasting

Impressive in its youth by the intensity of its structure and the brightness of its fruit, the wine of Cos d'Estournel evolves slowly to reach its complete maturity (between 10 and 30 years) an admirable blend and aromatic complexity.

Winemaking

Winemaking in Cos adapts to the character of the harvest, thus favoring the expression of the Terroir and this thanks to our new cellar. A demanding sorting of the grapes, pump-over by pure gravity carried out using 4 elevator tanks as well as precise control of fermentation temperatures favor the selection of the softest tannins and the preservation of the fruit.

Terroir

The word 'Cos' means, in old Gascon, 'the hill of pebbles'. The hill of Cos indeed raises, on the banks of the Gironde, an impressive accumulation of Quaternary gravels, torn from the distant mountains of the Massif Central and the Pyrenees and deposited on the limestone bedrock of Saint-Estèphe by the retreat of the primordial river. Shaped by erosion into well-drained ridges, these exceptionally deep gravels constitute a genuine geological curiosity and one of the world's most precious terroirs: they oblige the mature vines planted on their crests to send their roots very deep into the arid soil.
