Château Dauzac is home to 42 hectares of vines which are planted to a single block on deep gravel soils. Thomas Michel Lynch acquired Dauzac in 1740 and is responsible for establishing the reputation of this beautiful, large estate. In 1885, Ernest David, manager of both Dauzac and Ducru-Beaucaillou, perfected the Bordeaux mixture (copper sulphate and hydrated lime) here in conjunction with Professor Alexis Millardet in order to fight mildew and other fungi. The M.A.I.F. purchased this fine estate in 1988 and handed over management to André Lurton, who became President of the Executive Board in 1992. His daughter, Christine Lurton de Caix took over for him in 2005. The cellars were totally renovated in 2004 and now feature state-of-the-art winemaking equipment. The grapes are hand-picked into small crates and sorted twice (before and after destemming). The wine is aged in new barrels.
