What are typical signs of cork taint (TCA) in wine?

• A. Musty, moldy aromas and off-odor described as damp cardboard or mold.
• B. Bright fruit aromas and clean palate.
• C. Hints of vanilla and oak sweetness.
• D. Vibrant acidity with citrus notes.

Answer: (A)

Cork taint shows up mainly as a musty, moldy aroma that people often describe as damp cardboard or mold. This off-odor comes from TCA contamination and tends to overpower the wine’s fruit, leaving a dull, lifeless impression even if the wine is otherwise sound. That distinctive musty note is the clearest signal of cork taint. In contrast, descriptions like bright fruit with a clean palate, hints of vanilla and oak sweetness, or citrusy acidity point to wines that are fresh and well-made, not tainted. So the musty, damp-cardboard/mold aroma is the typical sign of cork taint.
