The winery is located in the commune of Margaux in the area of the same name in the Médoc (Haut-Médoc, Bordeaux). In 1661, the merchant Pierre des Mesures de Rausan (Rauzan) bought a large estate from the de Gassies family. This resulted in the creation of the Château Desmirail, Château Marquis-de-Terme and Château Rauzan vineyards. At the time of the French Revolution (1789-1799), Château Rauzan was divided in 1792 into the two wineries Château Rauzan-Gassies and the actual Château Rauzan-Ségla (but it was called Château Rausan-Ségla until 1994). The name came from the new owner Madame Ségla, a female descendant of the founder. The estate remained in the hands of the family until 1866. Subsequently, there were several owners, including the Cruse family.
In 1994, the company Château Rauzan-Ségla S.A. (a subsidiary of the Chanel perfume group) and carried out major renovations. In the 1855 Bordeaux classification, it was awarded second place (Deuxième Cru Classé). The vineyards cover 51 hectares and are planted with Cabernet Sauvignon (61%), Merlot (35%), Cabernet Franc (2%) and Petit Verdot (2%). The extremely long-lasting red wine matures for 18 to 20 months in 60% new barriques. It is counted among the "super-seconds", which would actually deserve the "Premier Cru Classé". The second wine is called "Ségla" (formerly "Château Lamouroux").
