Sainte Croix du Mont extends over 500 hectares (1,200 acres) and the grape varieties grown are Sémillon, Sauvignon and Muscadelle. It has a good geographical location for producing wine affected by noble rot as many of the vineyards grow next to rivers and are therefore likely to be affected by the Botrytis cinerea fungus in the autumn. The noble rot increases the sugar content, acidity, and glycerol content of the grape clusters.
