The great wine of Château Duhart-Milon is often described as a classic refined model of the Pauillac appellation, it presents a "distinction reserved with finesse". The appreciation of the broker Abraham Lawton, from 1815 "... he presents himself with a lot of firmness, good color and sap pronounced enough", is an illustration of the permanent character of Château Duhart-Milon.
The vineyard of Château Duhart-Milon is almost a block on the west side of Château Lafite Rothschild, on the hillside of Milon, which extends the plateau of the Carruades de Lafite. Château Duhart-Milon's property includes 76 ha of vines. The soils are fine gravel mixed with Aeolian sands on a subsoil of tertiary limestone. The 76 ha of vines are divided into Cabernet Sauvignon (67%) and Merlot (33%). The average age of the vineyard is 30 years old. The management of the property has been carried out since 1962 by a single team overseeing Château Lafite Rothschild and Château Duhart-Milon given the contiguity of the two properties. Eric Kohler, Technical Director of the Châteaux Bordelais, is assisted by Christophe Congé, Oenologist and Winemaker, and Régis Porfilet, Manager of the vineyards. The techniques used are quite identical between the two Châteaux and remain traditional, they incorporate a strict control of the yields, a harvest by hand and many works done manually throughout the year.
Each parcel is isolated at first to appreciate its ability to enter or not in the great wine after the end of fermentations. Several tastings of each vat are then carried out in December for a strict selection of the great wine. The cellars are located in the heart of the village of Pauillac. Each vintage is aged in oak barrels. The barrels come entirely from the Tonnellerie des Domaines. The duration of aging in barrels varies according to the vintages of 10 to 18 months during which the wines are periodically withdrawn and clarified with egg white. The average annual production of the estate (Château Duhart-Milon and Moulin de Duhart) is about 30,000 cases.
