The winery is located in the municipality Saint-Julien in the same area in Médoc (Haut-Médoc, Bordeaux). The name "Grand Vin de Léoville du Marquis de Las Cases" appears on the label, no chateau is mentioned. The last part of the name is derived from Marquis de Las Cases Beauvoir, the owner of a Château Léoville. This family remained in the possession of this family until 1840, when it was divided into three parts. In addition to the objective good are included Château Léoville-Barton and Château Léoville-Poyferré emerged. This subsequently came into the possession of the Delon family (descendants of the Léoville family), who also owned the Chateau Potensac heard. The progenitor was Théophile Skawinski, who ran the estate until 1930. From 1976 to 1996 Michel Delon gave the estate its current character and passed the management on to his son Jean-Hubert. In the Bordeaux Classification in 1855 the estate received second place (Deuxième Cru Classé).
The vineyards cover 97 hectares of vineyards with the varieties Cabernet Sauvignon (65%), Merlot (19%), Cabernet Franc (13%) and Petit Verdot (3%) are planted. The floor is similar to the famous one adjacent to the north Château Latour in Pauillac. The largest of the vineyards is completely enclosed by a wall (clos). The extremely long-lived red wine is aged for 20 months in 50 to 100% new barriques, depending on the vintage. The wine is counted among the so-called "super seconds", which due to its excellent quality would actually deserve the "Premier Cru Classé". It is believed that after Château Mouton-Rothschild the good could be the second that might be classified high. The 1970 vintage was with the legendary Paris Wine Tasting in 1976. The second wine is called "Clos du Marquis" and is one of the best in its genre. There is also a third wine called "Domaine de Bigarnon".
