Champagne Grethen was born in 1995 with Laurent and Annick Grethen, winemakers from Brouillet in the heart of the Vallée de l'Ardre, who, after having dedicated themselves to working in a cooperative for more than twenty years and having acquired new land, have made it possible the development of family brand. Since 2016, his son Antoine has assumed a fundamental role within the company, internalizing the winemaking process and converting all the processes of vineyard work to organic and biodynamic methods. In 2020, the 3 hectares of vineyards were certified in Organic Agriculture and Demeter.
