Historians date the origins of Calon back to the Gallo-Roman era. Its name is derived from the term “calones”, which were small transport boats that travelled up and down the Gironde estuary. Wine growing at the estate can be traced back to the 12th century, but it was in the 18th century, at the time of Nicolas-Alexandre the Marquis de Ségur, who also owned Latour, Lafite and Mouton, that the finest chapter of the property’s history was written. Calon thereafter was to be known as Calon Ségur.
