Quarts de Chaune is a sub-district of Chaume, one of two villages in the Coteaux du Layon, the other being Bonnezeaux, that is renowned for producing dessert wines. The Coteaux du Layon is located in the district of Anjou, with its vineyards strung out along the Layon river, which is a tributary of the Loire. All wines of the Coteaux du Layon are made from Chenin Blanc and this region produces many of the finest examples in the world.

The village of Chaume is located in the western part of the Coteaux du Layon and within Chaume, the Quarts de Chaume (or favored quarter), is an amphitheater-like setting with just 75 acres of vineyards. The wines of Quarts de Chaume must be made from late-harvested grapes and have a minimum of 3.4% residual sugar. They may or may not be affected by Botrytis. While the relatively drier wines provide great complexity and early drinking pleasure, those affected by noble rot, generally labeled Selection de Grains Nobles or SGN, have shown the ability to age for decades in the bottle and are among the world's finest dessert wines.
