Château Léoville-Las Cases is a winery in the Saint-Julien appellation of the Bordeaux region of France.
Léoville-Las Cases was one of the first estates in Bordeaux to introduce a second label, Clos du Marquis.
[2] Grapes are harvested by hand, crushed and then may be fermented in temperature controlled wood, concrete, or stainless steel vats of varying size depending on the style of the vintage.
Léoville-Las Cases also employs a state of the art reverse osmosis machine to help extract excess water from the grape must in a rainy vintage.
[3] After processing and fermentation, the wine is transferred into oak barrels for 18–20 months of aging before being fined with egg whites and bottled.
