Château Duhart-Milon, previously known as Duhart-Milon-Rothschild, is a winery in the Pauillac appellation of the Médoc, and ranked as a fourth growth in the 1855 Bordeaux Classification. The single 73-hectare (180-acre) vineyard block is situated just to the west of Lafite Rothschild, facing Lafon-Rochet in Saint-Estèphe. The soils are a mix of fine gravel and sand on limestone, and are planted two-thirds to Cabernet Sauvignon and one-third to Merlot, although the precise proportion of the grand vin blend can vary with each vintage – for example, the 2012 features 53 percent Merlot.
