Long considered as the second wine of Chateau Leoville-Las Cases, the Clos du Marquis, a historic vineyard of the Delon Estates became a Cru in its own right in 1902, the date of the birth of its first vintage.
The owners wanted to distinguish the terroir of Leoville-Las Cases from that of Clos du Marquis, which are 500 meters apart because of the different composition of the two soils. The vineyards cover nearly 45 hectares of gravelly soils, typical of the Medoc region, which provide excellent drainage and optimal thermal retention, favorable to grape ripening.
