Monbazillac vineyards in the autumn
The AOC of Monbazillac was first established in 1936, but the area has a long history of sweet wine production. Only wine made from grapes grown in Monbazillac that are affected by the "noble rot" (Botrytis cinerea) can be sold under the Monbazillac designation. (Dry white wines from the same area are sold as Bergerac sec.) The grape varieties Sémillon, Sauvignon blanc and Muscadelle are used for Monbazillac, and the permitted base yield is 40 hectoliter per hectare, although actual yields are lower for many producers.
