Eclavin WSET Level 1 - Episode 43
Real-World Exam Episode
If you observe a 'Brown color' in a young white wine and it smells like 'Vinegar' or 'Nutty Sherry' (when it should be fresh and fruity), what fault has occurred?
- A. Excessive carbonation
- B. Oxidation (Exposure to too much air)
- C. Cork Taint (TCA)
- D. Heat Damage (Cooked)
Critical Answer & Explanation
Answer: B. Oxidation (Exposure to too much air). Explanation: 1. Oxidation happens when a wine's seal fails or is left open too long, causing it to turn brown and lose its fresh fruitiness. 2. Cork Taint (TCA) is a chemical fault that makes a wine smell like damp, wet cardboard. 3. Heat Damage results in a 'cooked' raisin flavor and may cause the cork to leak. 4. Important: Physical pieces of cork in a glass are NOT a fault—simply a minor service error.

Expert Mastery Theory
Wine analysis is a 'Detective's Challenge.' 1. Fault vs. Feature: - Oxidation: A fault in most fresh wines but a 'feature' in styles like Oloroso Sherry or Tawny Port. - TCA (Cork Taint): *Always* a fault. It ruins the purity and freshness of the grape. 2. Detection Summary: - Visual: Look for unusual browning or cloudiness. - Nose: Any smell of musty cardboard (TCA), vinegar (Oxidized), or over-boiled fruit (Heat damaged)? 3. Correct Protocol: If you suspect a fault, the professional step is to replace the bottle immediately to ensure the best possible experience for your guest or yourself.
Pass-Guarantee Tip
[Trap]: Do not think that a slightly loose cork or a few crumbs of cork in the wine means it is 'Tainted.' TCA is a chemical smell of 'Musty/Wet Cardboard'. [Tip]: In a L1 exam, keywords like 'Vinegar / Brown Color / Flat' always lead to 'Oxidation'.
