Gaillac Doux AOC
Key French Terms
Southwest France's ancient sweet wine appellation, built on indigenous varieties and four distinct production methods with roots stretching to Roman times.
Gaillac Doux AOC produces naturally sweet white wines requiring a minimum of 70 g/L residual sugar from the Tarn department. The appellation draws on indigenous varieties led by Mauzac Blanc, produced through late harvest, noble rot, passerillage, or fortification. With AOC recognition dating to 1938, Gaillac is one of France's oldest continuously producing wine regions.
- Minimum 70 g/L residual sugar required for the Gaillac Doux designation
- Yields are capped at 40 hl/ha, stricter than dry Gaillac expressions
- Four approved production methods: late harvest, noble rot, passerillage, and fortification (mutage)
- Mauzac Blanc is the primary variety, prized for high botrytis susceptibility, waxy texture, and natural acidity of 5-7 g/L
- AOC officially recognized on March 21, 1938; viticulture in the region dates to the 1st century
- The appellation covers approximately 4,200 hectares across 73 communes in the Tarn department
- Five distinct terroir zones: Premières Côtes, Plaine du Tarn, Rive droite, Rive gauche, and Cunac
History and Origins
Gaillac is one of France's oldest continuously producing wine regions, with viticulture established during Roman occupation in the 1st century. Benedictine monks from the Abbey of Saint-Michel revived the vineyards starting in 972 AD, and by 1253 English King Henry III was purchasing Gaillac wines, ordering 20 barrels for the royal court. The former designations of Gaillac Liquoreux and Gaillac Moelleux were eventually consolidated into the unified Gaillac Doux classification. A quality renaissance began in the 1980s as producers turned their focus back to indigenous varieties, laying the groundwork for the appellation's modern reputation.
- Viticulture documented in the Tarn region from the 1st century AD
- Abbey of Saint-Michel monks revived production from 972 AD onward
- Henry III of England purchased 20 barrels in 1253
- Quality revival from the 1980s centered on native grape varieties
Terroir and Climate
Gaillac's approximately 4,200 hectares span 73 communes at elevations between 80 and 300 meters above sea level. The appellation sits under a continental climate tempered by both oceanic and Mediterranean influences, with hot, dry summers and rainfall concentrated between September and April. The Autan, a warm easterly wind, plays a critical role in accelerating ripening and managing humidity levels, making it especially relevant for sweet wine production. Soils vary dramatically across five zones: the right bank features clay-limestone mixtures; the left bank offers sand and river pebbles; the Cordes plateau is rich in limestone; and the Cunac area contains schist. This diversity, combined with 62 grape varieties in active production, gives Gaillac one of the most varied viticultural landscapes in France.

Grapes and Production
Mauzac Blanc leads Gaillac Doux production and is well suited to the appellation's sweet wine style. Its high susceptibility to botrytis, waxy texture, and natural acidity of 5-7 g/L allow it to produce wines with both richness and freshness. Permitted supporting varieties include Len de l'Œil, Ondenc, and Muscadelle. Four production methods are approved under the appellation rules: late harvest (vendanges tardives), noble rot selection (pourriture noble), passerillage (grape drying on the vine or indoors), and fortification (mutage). Each method requires specific documentation. Fermentation typically reaches 11-15% alcohol with no maximum ceiling, and indigenous yeasts are generally preferred to preserve the acidity needed for wines intended for aging.
- Mauzac Blanc is the primary variety with natural acidity of 5-7 g/L
- Supporting varieties: Len de l'Œil, Ondenc, and Muscadelle
- Four approved production methods, each with documentation requirements
- Indigenous yeasts favored to retain acidity for long-term aging potential
