Côtes de Duras AOC

Côtes de Duras occupies the right bank of the Dropt river, divided by the Dourdèze valley, roughly 70 kilometres east of Bordeaux and approximately 100 kilometres from the Atlantic Ocean. The appellation covers 15 communes in northern Lot-et-Garonne and sits as an eastern extension of the Entre-Deux-Mers appellation. It is bordered by Bergerac to the northeast, Entre-Deux-Mers to the southwest, and the Dordogne department to the northeast.

• Part of the Lot-et-Garonne department in Southwest France (Sud-Ouest)
• Eastern extension of the Entre-Deux-Mers appellation across the regional border
• Right bank of the Dropt river, with the Dourdèze valley bisecting the zone
• In 2014 officially became part of the broader Bergerac wine region while maintaining its own AOC

The appellation experiences a temperate oceanic climate with moderate Atlantic influence, though its greater distance from the coast produces slightly more extreme temperatures than Bordeaux. Mild springs and warm, sunny summers with southerly exposure characterise the growing season. Autumn morning fog combined with warm afternoons creates conditions conducive to Botrytis development, supporting the production of sweet white wines. Soils vary considerably across the zone: elevated slopes carry chalky, clayey limestone, while lower-lying areas near the river are covered in sandy boulbènes soils. The primary geological formations are Calcaire de Castillon (chalky white calcareous rock with cracks), Molasses de l'Agenais (clay and clay-sand alternating with gravel beds), and Calcaire blanc de l'Agenais (white calcareous).

• Temperate oceanic climate, slightly more extreme than Bordeaux due to distance from the coast
• Autumn fog and warm afternoons support Botrytis development for sweet wine production
• Three principal soil types: Calcaire de Castillon, Molasses de l'Agenais, and Calcaire blanc de l'Agenais
• Sandy boulbènes soils in lower-lying riverside areas; chalky clayey limestone on elevated slopes

Red wines, comprising 58% of production, are made from Cabernet Sauvignon, Cabernet Franc, Merlot, and Malbec (Côt). They range from supple and fruity to robust when aged in oak. White wines account for 36% of production and are led by Sauvignon Blanc and Sauvignon Gris, alongside Sémillon, Muscadelle, Mauzac, Chenin Blanc, and Ondenc, with Colombard and Ugni Blanc permitted as accessory varieties. Dry whites display a Sauvignon-like nose with vigorous flavours; sweet whites show candied fruit aromas. Rosé represents 4% of output and is made in a fresh, fruity style.

Wine production in Duras dates to the 12th century in the medieval village that gives the appellation its name. The wines gained royal attention during the reign of Francis I. After the revocation of the Edict of Nantes in the 17th century, local Protestant families emigrated to the Netherlands, establishing strong export trade to North Sea ports. Duras later became part of the Haut Pays Bordelais trading network, with wines handled by Chartrons merchants in Bordeaux. Although Bordeaux imposed protectionist duties on other Southwest wines, Duras paid only a quarter of those levies. By the early 20th century the region was primarily associated with sweet white wines. AOC status was granted on February 16, 1937, and in 2014 the appellation formally joined the Bergerac wine region while retaining its distinct AOC identity.
