Once the winemaking process has come to a close in our gravity-feed cellars in November, the first tastings of the newly crafted wines mark the start of blending.
A crucial step in the creation of a new vintage, blending allows us to bring together the different characteristics of the estate’s various terroirs in a single balanced wine. Even more spectacular than the sum of its parts, the final blend incarnates the identity of Cos d’Estournel’s complex terroir, whose one hundred hectares of vineyard include twenty types of soil! Derived from the old Gascon word for “hill of pebbles,” the name “Cos” is an explicit reference to the terroir’s predominant characteristic, which is complemented by the presence of clay, limestone and marl.
Adding to this extraordinary complexity is the vineyard’s diverse exposures to sunlight that results from its location at the edge of the plateau of Saint-Estèphe and the numerous slopes it offers. The grape varieties also bring more details to the whole picture, between Cabernet-Sauvignon, Merlot, Cabernet-Franc and Petit Verdot, as well as the ages of the vines, 45 years old on average.
