André Brément, the grandfather on the mother's side, was a vineyard worker who decided to plant his own vines.
André left his job to set up his own winery.
Alain Demets took over the family-run winery with his wife Marie.
The winery made its first Marie Demets Champagne in tribute to both families.
The first vintages went on sale.
Pierre, the grandson, joined the company after apprenticeships in Burgundy, Champagne and New Zealand.
Pierre took over his beloved company to keep the family legacy alive.
Mathilde joined the winery to provide her support.
A new vine growing and winemaking concept was rolled out with greater respect for the vines and wine itself.
