Or well aged first growth black mold, with a side of syphilis cultures.
Actually the black mold is bad. You want the Noble Rot.... Nothing like a side of athlete's foot to improve your sweet wines...
‘Noble Rot’ (aka Botrytis cinerea) is a type of Ascomycota within the Funghi kingdom. Other ascomycetes include the antibiotic penicillin, Stilton blue cheese and the fungus responsible for athelete’s foot. Botrytis cinerea can occur on fruits, vegetables and flowers –imagine a moldy strawberry. However with wine, it’s considered a good thing. Wines such as Sauternes from Bordeaux; Tokaji Aszu from Hungary, and Spätlese level German Riesling all are made from ‘Noble Rot’ grapes.
