Sauternes is a sweet, complex, and balanced French dessert wine. It's made from grapes that have been affected by Botrytis cinerea, also known as noble rot. This fungus causes the grapes to shrink and concentrate their flavor. Sauternes is made in the Graves section of Bordeaux, in the region of the same name. The wine is made from a blend of grapes, including: Sémillon, Sauvignon blanc, Muscadelle.
