Noble Rot
Also known by its scientific name, Botrytis cinerea, noble rot is a beneficial mold that grows on ripe wine grapes in the vineyard under specific climatic conditions. The mold dehydrates the grapes, leaving them shriveled and raisinlike and concentrates the sugars and flavors. Wines made from these berries have a rich, complex, honeyed character and are often high in residual sugar. Noble rot contributes the unique, concentrated flavors in such wines as BA and TBA Riesling from Germany, Sauternes from Bordeaux, Aszu from Hungary’s Tokay district and an assortment of late-harvest wines from other regions.
