The Vrignauds’ family, settled in the village of Fontenay-près-Chablis, have been vine growers for five generations. They began planting in 1er cru Fourchaume with the Côte de Fontenay climate in 1955. In 1975, they planted the rest of their vines around Fontenay près Chablis and also Fleys for the 1er cru Mont de Milieu. It is a quality-conscious family with an absolute belief in the importance of work in the vines, respect for nature and biodiversity.

In 1999, Guillaume Vrignaud started to bottle his first wines and decided to build a new winery. 2009 marked the start of organic certification by Ecocert. According to him, organic farming is not an end, it is a way of thinking, a way of revealing the terroir. In 2012, all Guillaume wines across their 28 hectares were organic certified and have been ever since.
