Since taking over his family’s estate in 1990, he has become an ardent defender of region’s terroir and one of the most highly respected producers in three of Chenin’s greatest appellations: Quarts de Chaumes, Savennières and the Coteaux du Layon. As the President of the Quarts de Chaumes Syndicat and the head of the Centre Technique Interprofessionnel de la Vigne et du Vin, he has been a powerful advocate and the leading force behind the INAO’s decision to bestow the Quarts de Chaume with grand cru status and the Coteaux du Layon with premier cru status in 2011.
