Since 1932, Bonnaire Champagne whose vineyard is located in Cramant, a village that is classified Grand Cru from the Côte des Blancs, elaborates its Champagne. The vineyard has long been property of the Bouquemont family and it was right after the second World War that André Bonnaire, by marriage, inherited the vineyard, which spreads today on around 25 hectares. The Bonnaire have also been a family of winegrowers for several generations.

Jean-Louis Bonnaire, with help from his two sons Jean-Etienne and Jean-Emmanuel currently manages this Grand Cru Cramant House, located in the heart of the Champagne region.
