Etienne Barre and Christophe Reboul Salze bought Chateau Les Grands Marechaux located in the Cotes de Blaye appellation in 1997. However, this is not their only vineyard in the region.

They also own Chateau Chateau Gigault, which makes the popular Cuvee Viva. They recently added to their portfolio of Bordeaux value wine-producing estates with the purchase of Chateau Belle Coline. Aside from being a Bordeaux winemaker, Christophe Reboul is also well known as a Bordeaux wine negociant with his company, The Wine Merchant. The 21.4-hectare, Chateau Les Grands Marechaux vineyard is planted to 84% Merlot, 9% Cabernet Franc and 7% Cabernet Sauvignon. The terroir is clay, limestone, and sandy soils. The average age of the vines is 17 years.

To produce the wine, the fruit is whole berry fermented in temperature-controlled, stainless steel tanks with a 30-day maceration. Malolactic fermentation is performed in French oak barrels. The wine-making and vineyard management of Chateau Les Grands Marechaux is consulted by Stephane Derenoncourt who is well known for working with numerous estates in the Right Bank of Bordeaux.
