Noble rot

Noble rot (or pourriture noble) is a type of fungus that can affect grapes, causing them to shrivel and concentrate their sugars. This can result in some of the world's most famous and expensive dessert wines. The fungus responsible is Botrytis cinerea.

Causes and Effects

Noble rot occurs when certain conditions of humidity and temperature are met, allowing the Botrytis cinerea fungus to infect the grapes. The fungus pierces the skin of the grape, which leads to water evaporation, making the grape shrivel. As the grape loses water, its sugars and other solids become more concentrated. This process can contribute to the unique flavor of the resulting wine.

Noble Rot Wines

Wines made from grapes affected by noble rot are often sweet and complex, with a unique flavor profile that can include honey, ginger, and dried fruit notes. Some of the most famous noble rot wines come from the Sauternes region of France, but the process can occur anywhere the conditions are right. Other regions known for noble rot wines include Tokaj in Hungary and Rheingau in Germany.
