Situated in Libourne along the Dordogne River, the Etablissements Jean-Pierre Moueix, of which Château Hosanna is a part, was founded in 1937. It is internationally known for its expertise in the Bordeaux wines of Pomerol and Saint-Emilion.
The company began its history as a wine merchant, specializing in the wines from the right bank of Bordeaux. The founder, Jean-Pierre Moueix, became one of the most influential people of the area when he began investing in properties of the region in 1952. At this time, the vineyard owners had no control over the finished product, since the "négoce" (negociants) of Bordeaux controlled the bottling and the sales. Mr. Moueix understood the market and what needed to be done. He was a visionary. The company is now managed by his son, Christian.
