Practice Question
If a wine has an unpleasant odor like Damp Cardboard or a moldy basement, what fault can you suspect?
- A. Oxidation
- B. Cork Taint (TCA)
- C. Cooked Wine (Heat Damage)
- D. Bottle Aging
Answer & Explanation
Answer: B. Cork Taint (TCA) Explanation: The TCA (Trichloroanisole) compound, created by a chemical reaction between molds living on the cork and disinfectants, can ruin the wine's aroma even in very small amounts. This phenomenon, which kills the wine's natural fruit aroma and causes wet newspaper, cardboard, and musty basement smells, is also called being 'Corky', and while it's harmless to the human body, the taste is completely ruined.
Key Theory Summary
These are the 3 main symptoms that appear when a wine is 'sick'. 1. Cork Taint (TCA): - Symptom: Wet paper, musty basement smell. Loss of fruit aroma. 2. Oxidation: - Symptom: White wine changes to amber, red to brown. Scents like vinegar or Sherry instead of fresh aromas. 3. Heat Damage (Cooked Wine): - Symptom: Cooked fruit aroma. The cork slightly pops up above the bottle or there are signs of leaking.
Expert Exam Tip
[Trap]: Thinking "If pieces of cork are floating in the wine, it's a faulty wine" is incorrect. This is simply a mis-opened bottle or a dry cork, and is different from a fault (TCA) that affects the taste. [Tip]: In the exam, if you see the phrase 'Damp Cardboard', choose 'Cork Taint' without a second of hesitation!
