Chateau Cantemerle, located in the Haut-Medoc appellation of Bordeaux, is one of eighteen Cinquiemes Crus (Fifth Growths) in the Bordeaux Wine Official Classification of 1855. At the end of the 20th century, the land was sold to a French insurance group. This group has invested heavily in the estate, planting an additional 70 hectares, purchasing new oak barrels to replace stainless steel tanks, and installing new harvesting and sorting equipment. Currently, the Chateau owns 190 hectares, about half of which is planted with vines, with an average vine age of 30 years old and some vines nearing 70 years. Production is split almost evenly between Cabernet Sauvignon and Merlot. The wines are aged in oak barrels for 12 to 15 months, and Cantermerle produces about 25,000 cases annually.
