Château Montrose is a winery in the Saint-Estèphe appellation of the Bordeaux region of France. The wine produced here was classified as one of fourteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855.
Chateau Chasse Spleen is a winery in the Moulis en Medoc appellation to the west of Margaux. The 80 hectares (200 acres) of vineyards are planted with around 70 percent Cabernet Sauvignon, mostly on gravel, and 25 percent Merlot in areas with a strata of clay under the gravel or with clay over limestone. The remaining 5 percent is planted to Petit Verdot. Plantings are very dense at 10,000 vines per hectare. The different varieties are fermented in stainless steel or epoxy-lined concrete vats of 18,000 liters, and then aged for up to 18 months in barriques. The different components are then blended and fined with albumen before bottling.
