Chateau La Lagune is an estate ranked as a third growth in the 1855 Bordeaux Classification a the highest rating for any property in the Haut-Medoc. The organically farmed vineyard covers 80 hectares (200 acres) on a south-facing gravel hill of well-drained white pebbles which reflect the sun back onto the fruit to aid ripening. It is planted 60 percent to Cabernet Sauvignon, with 30 percent Merlot and an unusually high 10 percent of the demanding Petit Verdot. A second wine, Moulin La Lagune, is produced from younger vines which do not make the grade for the grand vin. Since 2004, a third wine, Mademoiselle L, has been made from another 30-ha (74-acre) plot further down the La Lagune slope. It is a 50-50 blend of Cabernet Sauvignon and Merlot and is intended to be drunk young.
