Château Dauzac

Château Dauzac is a winery in the Margaux appellation of the Bordeaux region of France, in the commune of Labarde. The wine produced here was classified as one of eighteen Cinquièmes Crus (Fifth Growths) in the Bordeaux Wine Official Classification of 1855. Since 1988, the estate has belonged to the insurance company MAIF, but is managed by the André Lurton group. In 2004, his daughter Christine Lurton-Bazin de Caix took charge of the property.

In the 1880s, the trials which led to the development of the Bordeaux mixture to combat downy mildew mostly took place in the vineyards of Château Dauzac. They were conducted by professor Pierre-Marie-Alexis Millardet, assisted by Dauzac's technical director Ernest David.

The domaine comprises 297 acres (120 ha), of which 111 acres (45 ha) are planted, 60% with Cabernet Sauvignon grapes and 40% with Merlot. The average age of vines is around 30 years. The Château produces the main wine, Château Dauzac, from the 104 acres (42 ha) planted in the Margaux appellation, as well as a second wine named La Bastide Dauzac. The estate also owns 7.5 acres (3.0 ha) in the Haut-Médoc appellation, from which it produces a third wine, Château Labarde.
