Because of exclusive terroirs are the two independent appellations Bonnezeaux and Quarts de Chaume, The Chaume area (within the municipality of Rochefort-sur-Loire) has a special status. From the 2003 vintage, the wine was marketed under the AOC name Coteaux du Layon Chaume . However, this led to confusion and discussions, because there is also the independent AOC Quarts de Chaume in the municipality of Rochefort-sur-Loire.
