Domaine Blain-Gagnard was formed in 1980 when Jean-Marc Blain (a Sancerrois) married Claudine Gagnard, youngest daughter of Jacques and Marie-Josèphe Gagnard of Domaine Gagnard-Delagrange. The couple runs this venerable domaine with the help of their son Marc-Antonin. Jean-Marc Blain and Claudine Gagnard met while they were both studying oenology at Dijon. The estate's vineyards come mainly from grandparents and other relatives of Claudine, along with a few purchases. The vines are planted in Chardonnay (55%) and the rest in Pinot Noir, with a small parcel of Passetoutgrain.
