Clos du Marquis is the second label of Chateau Leoville-Las-Cases. Its name comes from a small walled parcel of land, in French a “clos,” located near the residence of the Marquis de Las-Cases. Clos du Marquis was produced and sold by Chateau Leoville-Las-Cases starting in the late 19th century, which makes it one of the very earliest of the so-called second wines now produced by many Bordeaux estates. The wines are generally made from the fruit of younger vines which are not considered mature enough to produce fruit for the estates’ signature wines. However, they often represent an excellent value and Robert M. Parker Jr. has written that Clos du Marquis in the last 20 years “has been close to the quality of a third or fourth growth.”
