The origins of Domaine Pascal Lejeune date back to the beginning of the 19th century, when Edmond, the great-grandfather of Sandrine, the fourth generation and current owner, cultivated a few hectares of vines in Moussy, on the southern slopes of Epernay; although, at that time, vines were not yet important and the entire production was sold to the local cooperative. Since then, the management of the Domaine has passed from hand to hand in the family until, in the mid-1950s, they began selling Champagne under their own brand name.
