Barsac
Barsac is a wine region, known for sweet, dessert wines made from Botrytis-affected Semillon and Sauvignon Blanc grapes. Barsac is one of the communes of Sauternes, in France. Just to make things more complicated, Sauternes is also "one of the communes of Sauternes." That's right, there are two uses for the name Sauternes, the general one, and the more specific one. The region of Sauternes has five communes and one of them is named Sauternes, also.
