Château Montrose is a winery in the Saint-Estèphe appellation of the Bordeaux region of France. The wine produced here was classified as one of fourteen Deuxièmes Crus (Second Growths) in the original Bordeaux Wine Official Classification of 1855.
Château Dauzac is a producer making Cabernet Sauvignon-dominant Bordeaux blends in the Labarde commune of Margaux, and was ranked a fifth growth in the 1855 Classification of Medoc and Graves. Today, the Dauzac estate covers 120 hectares (295 acres) of land, 45ha (111 acres) of which are planted to vineyards. These are roughly at a 65 percent to 35 percent ratio of Cabernet Sauvignon to Merlot. This vineyard provides fruit for the grand vin and the second wine, Labastide Dauzac, while a 3-ha (7-acre) plot in the Haut-Médoc provides fruit for Dauzac's third wine, Château Labarde. A fourth wine, Aurore de Dauzac, was made exclusively in the 2013 vintage.
