The vineyards, which average 45 years of age, mostly planted to old varieties of Merlot and the rest Cabernet Franc, are situated on the gentle slopes of the plateau in Montagne, Saint-Émilion, Pomerol and Libourne. The soils here are clay-based, and provide the best raw material possible to make the classic wines of the region. As previously stated the are farmed with the strictest organic principles, with harvesting done by hand.
Their flagship label, Maison Blanche, is a blend of Merlot and Cabernet Franc from old vines with incredibly low yields. It ages for 18 months in barrel before being bottled with very little sulfur. This is serious and structured without being too heavy and has the stuffing for cellaring.
