Catherine et Pierre Breton own 27 acres of vineyards near Bourgueil, in the Loire Valley. The couple started their commercial winery in 1982 and today produce about 7,000 cases of Chinon, Bourgueil and Vouvray. They have practiced biodynamic farming since 1994. They grow primarily Cabernet Franc, which is often called Breton in the Loire Valley, and Chenin Blanc. Robert M. Parker Jr. has called the couple “icons among France’s sustainable-viticulture set” and notes that “Pierre Breton tailors his vinifications with impressive sensitivity and adaptation to a diversity of terroirs and styles.”
