History
Cos d'Estournel Blanc was launched with the 2005 vintage as a premium white from a dedicated 10-hectare parcel, drawing strong commercial demand for white Bordeaux from outside the traditional Graves and Sauternes appellations. The combination of organic viticulture and barrel fermentation established it as a reference point for white Medoc wines.
