Eclavin WSET Level 1 - Episode 39
Real-World Exam Episode
If a wine smells strikingly like 'Wet Cardboard' or a 'Musty Basement' and its fruit flavors seem muted, what common wine fault is likely responsible?
- A. Oxidation (Exposure to too much air)
- B. Cork Taint (TCA)
- C. Heat Damage (Storage in too warm a place)
- D. Excessive carbonation in a still wine
Critical Answer & Explanation
Answer: B. Cork Taint (TCA). Explanation: 1. Cork Taint is caused by a chemical compound called TCA. Even in tiny amounts, it can ruin a wine, making it smell like damp cardboard or a moldy cellar and stripping away its vibrant fruit character. 2. Oxidation occurs when a wine is exposed to too much oxygen, making it taste flat, brown in color, and vinegar-like. 3. Heat Damage happens when wine is stored in a warm place, resulting in 'cooked' or stewed fruit flavors (like raisins).

Expert Mastery Theory
Wine analysis is a 'Detective Game.' 1. Cork Taint (TCA): A chemical fault, not a physical one (bits of cork in wine are not a fault!). Symptoms: Musty, damp cardboard, muted fruit. 2. Oxidation: Too much air. Results in browning (like a sliced apple left out) and flavors of vinegar or nutty sherry (when not intended). 3. Heat Damage (Cooked): Caused by storage near a radiator or in a hot car. Signs: Raisiny, stewed fruit, and a leaking cork (due to expansion). 4. Visual Indicators of Faults: - Clarity: Is it unusually cloudy (undesirable)? - Color: Is a young white wine strangely brown or deep amber?
Pass-Guarantee Tip
[Trap]: Do not mistake 'bits of cork' floating in the wine for 'Cork Taint.' Pieces of cork are simply a minor physical nuisance—TCA is a chemical smell! [Tip]: In a L1 exam, 'Wet Cardboard' is the hallmark of 'Cork Taint (TCA)'.
