Eclavin WSET Level 2 - Episode 40
Real-World Exam Episode
What is the fundamental technical reason why a Port wine from Portugal typically tastes 'Sweet'?
- A. A large amount of sugar is added after fermentation is fully complete.
- B. During fermentation, high-strength grape spirit is added, which kills the yeast and stops the fermentation.
- C. Grapes are dried in a warm climate to evaporate water before fermentation begins.
- D. Low acidity and low tannins naturally make the sugar feel more intense.
Critical Answer & Explanation
Answer: B. During fermentation, high-strength grape spirit is added, which kills the yeast and stops the fermentation. Explanation: The timing of fortification is the defining factor for Port. While the must is still fermenting, high-alcohol grape spirit (around 77% abv) is added. This raises the overall alcohol to 19-22%, which kills the yeast instantly. Because the yeast stops working, the natural grape sugars that haven't been converted to alcohol remain in the wine, creating Port's signature lush sweetness.

Expert Mastery Theory
Fortified wines are defined by 'when the spirit is added' and how they are matured: 1. Sherry (Spain - Jerez): - Fortification: Added after fermentation is complete. Thus, base Sherries are naturally dry. - Fino Sherry: Aged biologically under a layer of yeast called 'Flor.' (Aromas of bread dough, almonds, and citrus). - Oloroso Sherry: Aged oxidatively without Flor. (Aromas of walnut, caramel, and dried fruit). 2. Port (Portugal - Douro): - Fortification: Added during fermentation. Always sweet and high in alcohol. - Ruby Styles (Ruby, Reserve, LBV): Focus on vibrant black fruit and plum notes. - Tawny Styles: Aged oxidatively to develop notes of walnut, toffee, and roasted coffee. 3. Solera System: Sherry’s unique fractional blending system that ensures consistent quality and style year after year.
Pass-Guarantee Tip
[Trap]: Do not assume all Sherry is sweet. Fino and Oloroso are fundamentally 'Dry' wines. (Sweetened versions like 'Cream Sherry' are separate blends). [Tip]: Link 'Bread Dough' and 'Flor' to 'Fino Sherry'. Link 'Nutty' and 'Caramel' to 'Tawny Port' or 'Oloroso'. Timing is everything.
