At the end of the First World War, Maurice Doyard bought a vineyard and buildings in Vertus.

He started the commercialization as grower-handling in 1927 and deals alongside the Champagne professional organization.

This activity led him to chair the General Union of Winemakers and the CIVC (Interprofessional Committee of Champagne Wines) he was with M. de VOGUE (Moet et Chandon house) co-founded in 1941.

The Doyard family is closely linked to the history of champagne including all qualitative regulations in place at that time.
