Château Calon-Ségur is the most northerly of the Médoc Grand-Crus Classés. The former owner, Marquis de Ségur who also owned Lafite and Latour, declared that his heart belonged to Calon, hence the heart which features on the label. For the last century it has been owned by the Gasqueton family. In 2012, the Gasqueton family sold Château Calon Ségur and Château Capbern to Suravenir, a subsidiary of the Crédit Mutuel Arkéa group. Jean-Pierre Denis, its chairman, formed a partnership with Jean-François Moueix and his son Jean, the owners of the Videlot group. Together they have conducted renovation works with outstanding results.
The partly-walled vineyard covers 74 hectares and is planted on deep gravel beds with 65% Cabernet Sauvignon, 20% Merlot and 15% Cabernet Franc. The wine is matured in oak barrels (40% new) for 18 months.
