In the first quarter of the late 18th century, Alexandre de Ségur owned the LATOUR, LAFITE and MOUTON estates. He was known as The Prince of vines » for he promoted his vineyards to a prestigious destiny and bequeathed them to his son, Nicolas Alexandre. Due to his marriage, Nicolas de Ségur took possession of Château de Calon, and he enthusiastically said: I already make wine at Latour and Lafite, but my heart belongs to Calon. Like his father, he pulled up the estate by setting a high level of requirement and contributed to the prestige of his wines.
