Based in the heart of the Côte des Bar in Celles-sur-Ource—a village famed for its innovative grower-producers, such as Cédric Bouchard, master-craftsman of Champagne Roses de Jeanne, and Aurélien Gerbais (Champagne Pierre Gerbais), rising star of the Aube département—Julien Prélat, fourth-generation vine grower and first-generation vigneron, has tended to vines here since 2000.
