uncertaintimes:Noble rot on Riesling grapesNoble rot (French: pourriture noble; German: Edelfäule; Italian: Muffa) is the benevolent form of a grey fungus, Botrytis cinerea, affecting wine grapes. Infestation by Botrytis requires moist conditions, and if the weather stays wet, the malevolent form, “grey rot”, can destroy crops of grapes. Grapes typically become infected with Botrytis when they are ripe, but when then exposed to drier conditions become partially raisined and the form of infection brought about by the partial drying process is known as noble rot. Grapes when picked at a certain point during infestation can produce particularly fine and concentrated sweet wine. Some of the finest Botrytized wines are literally picked berry by berry in successive tries (French for “selections”). -- source link
