Botrytis cinerea



  • a fungus that attacks grapes and causes them to rot and shrivel up. If a white grape is attacked by this fungus, it has the effect of concentrating the grape’s flavour and sweetness and, if carefully controlled, can be used to enhance the sweetness and flavours of sweet white wines. When this fungus attacks red grapes, the rot simply ruins the grape. When it attacks white grapes, it is also known as noble rot or noble mould (in English), pourriture noble (in French), Edelfäule (in German) and muffa nobile (in Italian).
