Muscadelle is a white wine grape. It has a simple aroma of grape juice and raisins like grapes of the Muscat family of grapes, but it is unrelated.
In France, it is a minor constituent in the sweet wines of Bordeaux, such as those of Sauternes and Barsac. It rarely makes up more than 10% of the blend, which is dominated by Sémillon and Sauvignon Blanc
