The former owner and namesake Louis Gaspard d'Estournel was known as the Maharaja of Saint-Estèphe. He decorated the castle in Indian style, gave great parties and lived beyond his means. In 1852 he was completely penniless and had to sell his domain. A year later he died. Cos d'Estournel is perhaps the Chateau with the most new and advanced winemaking technique. From picking to maturing the bottles, everything is carefully checked and carried out with the greatest care. In this way they have managed to create a vinification process in which the wine is transported without pumps. All operations are carried out by gravity. In 1855, the Chateau obtained the 2nd Grand Cru Classe status
