This classic château has one of the greatest terroirs of Bordeaux. Those who tasted the wines made here in the late 1940s and 1950s will know that the potential of Calon is huge. Since the sale of this 55 hectare property to French insurance company Suravenir by the Gasqueton family, there has been huge investment in - and modernisation of - the wine-making facilities. There has also been much work done in the vineyards and quality is now right back to top "super-second" levels. The vineyard is planted with 56% Cabernet Sauvignon, 35% Merlot, 7% Cabernet Franc and 2% Petit Verdot. Calon Ségur now vies with Montrose and Cos d'Estournel for the title of top Saint Estèphe..
