Chateau Haut Rian is owned by Michel Dietrich, who hails from Kaysersberg in Alsace, where he grew up in a winemaking family. He has degrees in viticulture and oenology from the College of Beaune and the University of Bordeaux. The property is eighty hectares, encompassing parts of the Premieres Cotes de Bordeaux and Entre-Deux-Mers, bordering the village of Cadillac and near the Garonne River, 'where the vines can see the water but won't get their feet wet'.
The climate here is warmer than maritime Medoc but also drier. All of the vineyards are on gentle slopes facing South and Southeast, the topsoil consists of loose pebbles over limestone. This rose is 50% Merlot, 40% Cabernet Franc and 10% Cabernet Sauvignon.
