Coteaux du Layon is an Appellation d'origine contrôlée (AOC) for sweet white wine in the Loire Valley wine region of France. Coteaux du Layon is situated in the Anjou district of the region, along the river Layon, which is a tributary of the Loire River. Six of the villages (communes), namely Beaulieu-sur-Layon, Faye-d'Anjou, Rablay-sur-Layon, Rochefort-sur-Loire, Saint-Aubin-de-Luigné and Saint-Lambert-du-Lattay are allowed to add their name to that of the appellation. Usually, the "de" or "sur" part is dropped, to give names like Coteaux du Layon Beaulieu and Coteaux du Layon Saint-Aubin. Furthermore, two villages within the Coteaux du Layon area form their own respective AOC – Bonnezeaux and Chaume. Finally, a favoured enclave within Chaume is a separate AOC under the name Quarts de Chaume. For the geographically delimited AOCs, required grape maturity is higher and allowed yield is lower. The best vineyards are generally located on the north bank of the Layon, where they enjoy a good sun exposure on roughly south-facing slopes. Coteaux du Layon including its enclave appellations cover about 1,400 hectares in the early 2000s.
