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.
The winery's history dates back to 1857 with the Nié-Vantey family. Over the years, it passed through several generations, with significant contributions from Georges Lochardet and his descendants. In 2011, Armand Heitz, the grandson of Armand Lochardet, took over the estate and introduced innovative practices like biodynamic farming and later permaculture.
