Bunch Rot positive effect under favorable conditions is which of the following?

• A. Increased acidity
• B. Noble Rot or Botrytis affected grapes
• C. Moldy off-flavors
• D. No effect

Answer: (B)

Under favorable conditions, a beneficial form of bunch rot occurs known as noble rot, caused by Botrytis cinerea. The right mix of humidity and dryness allows the fungus to colonize grape skins and slowly desiccate the berries. This concentrates sugars, acids, and aromatic compounds, producing grapes that are intensely flavored and suitable for high-quality dessert wines. The result isn’t just more acidity; it’s a controlled concentration that, when made into wine, yields complex, sweet, yet balanced styles like Sauternes or Tokaji. This distinguishes noble rot from moldy off-flavors or a lack of effect, which don’t provide that desirable, specialized concentration.
