Maison Blanche is a Bordeaux winery that extends over 40 hectares in the south-west of the Montagne Saint-Émilion appellation, between Lalande-de-Pomerol to the north and Saint-Émilion to the south. The grape varieties are 60% Cabernet Franc and 40% Merlot, with vines on average 45 years old, on clay soils mixed with limestone and iron grime.

Maison Blanche is undoubtedly a pioneer of organic and biodynamic viticulture in Bordeaux, with the adoption of biodynamics in 2001. Nicolas Despagne is the passionate craftsman and in 2005, converted all the family vineyards to organic farming: Maison Blanche, Tour de Corbin-Despagne, La Rose Figeac. It obtained Ecocert certification in 2009. In 2013, he obtained the Demeter certification in biodynamics from Maison Blanche.

The history of Maison Blanche dates back to the Gallo-Romans when the road from Bordeaux crossed its grounds to Lucaniacus, the nearby villa of the famous proconsul and poet Ausonius. In the 15th century, they were attached to the seigneury of Corbin.

The modern history, and the real development of the estate, goes back to Louis Rapin, a Libourne wine merchant, who acquired it in 1938. He enlarged and replanted the vineyard and it was his daughter Françoise who took over the reins in 1969 with her husband Gérard Despagne. In 1972, Louis Rapin's estate gave them the 40 hectares of Maison Blanche, 2 hectares of La Tour Figeac, Saint-Emilion Grand Cru Classé, and the small vineyard of La Rose Figeac in Pomerol. In turn, they undertook audacious developments, doubling the surface area of the cellars and the volume of the vat room and having a barrel cellar of nearly 650 m² built in 1992, which then became the largest on the right bank. Their children, Nathalie and Nicolas, joined them in 1994 and 1995 as partners in the management of the properties and then became co-managers in 2003. Nicolas Despagne became the sole manager in 2013.
