Gonet-Médeville is a very young Domaine, founded in 2000 from the union of Xavier Gonet and Julie Médeville, heirs to two great winemaking traditions: the Champenoise tradition of Le Mesnil-sur-Oger and the Bordelais tradition of Sauternes. The Domaine is based in Bisseuil, a Premier Cru in the Vallée de la Marne, and owns 12 hectares divided among three Grand Cru villages (Le Mesnil-sur-Oger, Oger, Ambonnay) and three Premier Cru villages (Bisseuil, Mareuil-sur-Aÿ, Trépail), all located in outstanding lieux-dits.
