Château Calon-Ségur is a winery in the Saint-Estèphe appellation of the Bordeaux region of France. The wine produced here was classified as one of fourteen Troisièmes Crus Classés (Third Growths) in the historic Bordeaux Wine Official Classification of 1855. [1] It is the northernmost classified growth in the Médoc. The winery was owned by Nicolas-Alexandre, marquis de Ségur who also owned Chateau Latour and Chateau Lafite. Despite his ownership of these two First Growths, the Marquis said that his "heart was with Calon" and the wine's label today includes a drawing of a heart around the Chateau's name.
