What type of wine is produced in the Coteaux du Layon?

Coteaux du Layon is renowned for producing sweet wines made primarily from the Chenin Blanc grape. This area, located in the Loire Valley of France, benefits from the region's characteristic conditions that promote the development of noble rot, or Botrytis cinerea. This fungus enhances the sugars and flavors within the grapes, resulting in concentrated, rich wines with notable sweetness balanced by acidity.

The distinctive profile of Coteaux du Layon wines, often described as having flavors of honey, stone fruits, and citrus, arises from this process. The appellation is dedicated to producing these luscious dessert wines that showcase the capabilities and versatility of Chenin Blanc in suitable terroirs.
