This hilly area, located on the Right Bank, was first formed in 2009 with the union of four regions: Côtes de Blaye, Côtes de Castillon, Côtes de Francs and Côtes de Cadillac. In 2016, Sainte-Foy Bordeaux joined the group. Together, they cover nearly 30,000 acres of vines, and represent 10 percent of total production of bordeaux .
