Botrytis cinerea is the mold (fungus) referred to as the “Noble Rot” (in French “Pourriture Noble, German “Edel Faule”) that can form on the skins of grapes under very special circumstances. The result of botrytis cinerea is that the flavor of the grapes becomes highly concentrated. This comes from the fact that the mold suctions water from the grape which further concentrates the juice resulting in a very high sugar content. The resulting wines are very sweet and have a deep, honey-like luscious flavor. Many “Late Harvest” wines, the Sauternes and Barsacs of France, as well as the dessert wines of Germany, are famous as a result of the Noble Rot.
