The winery is located in the Pauillac area near the eponymous municipality of Milon in the Médoc(Bordeaux). Its immediate neighbours are the two famous estates Château Lafite-Rothschild and Château Mouton-Rothschild. According to a document from 1815, it belonged to the Mandavy family. Between 1830 and 1840, the estate and a further 14 hectares came into the possession of the Castéja family (Borie-Manoux) by inheritance from the widow Duhart and was given the name Duhart-Milon. According to Castéja family lore, the lord of the manor Duhart was a former pirate of King Louis XV (1710-1774) who retired in Pauillac. The "pirate's house" in the harbour of Pauillac stood until the 1950s and inspired the Duhart-Milon label. In the 1855 Bordeaux classification, the estate was awarded fourth place (Quatrième Grand Cru Classé).
The estate remained in the family until 1937 and was then split up by five different owners. The devastating frost of 1956, which affected the whole of Central Europe, did the rest. In 1964, the run-down estate was acquired by Domaines Barons de Rothschild S.A. with only 16 hectares left at the time. The French branch of the Rothschild family also owns Château Lafite-Rothschild, among others. After the takeover, all the vineyards were replanted. Neighbouring plots were purchased and others were replaced for the purpose of land consolidation. At the same time, new wine storage and fermentation cellars were built in Pauillac. The vineyards cover 76 hectares and are planted with Cabernet Sauvignon (70%) and Merlot (30%). The extremely long-lasting red wine is matured for 18 to 24 months in barriques, 50% of which are new. The second wines are called "Moulin de Duhart" and "Baron de Milon".
