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.
