Eclavin WSET Level 2 - Episode 8
Real-World Exam Episode
What is the primary geographical factor that allows for the production of premium wines with 'cool-climate' characteristics, even in relatively warm or low-latitude regions near the equator?
- A. Extremely fertile soil
- B. High Altitude
- C. High intensity of gale-force winds
- D. Large expanses of flat plains
Critical Answer & Explanation
Answer: B. High Altitude Explanation: Even in regions with low latitudes (nearer the equator) and high temperatures, increasing altitude leads to a significant decrease in temperature. On average, the temperature drops by approximately 0.6°C for every 100 metres of elevation. For instance, in regions like Mendoza, Argentina, establishing vineyards at high altitudes allows winemakers to maintain the elegant acidity and fresh fruit profiles typically found in much cooler climates.

Expert Mastery Theory
Latitude and altitude are the two fundamental geographical factors that dictate the average temperature of a vineyard: 1. Latitude: As you move away from the equator (0°) toward latitudes between 30° and 50° in both the Northern and Southern Hemispheres, temperatures generally decrease. This ideal zone is often referred to as the 'Wine Belt.' 2. Altitude: Higher altitudes lead to cooler temperatures. This Cooling Effect enables the production of fresh-style premium wines even in otherwise hot regions. (Examples: Mendoza in Argentina, high-altitude plateaus in South Africa). 3. Effect: Cooler temperatures help preserve a wine’s Acidity and maintain fresh fruit aromas, which significantly enhances the wine’s overall structure and aging potential.
Pass-Guarantee Tip
[Trap]: Do not assume that "High latitude (above 50°) automatically guarantees a good wine." If the latitude is too high, the grapes may fail to ripen, resulting in thin, green, and overly acidic flavours. A balance between sunlight and warmth is essential. [Tip]: In the L2 exam, if you see the word 'Altitude', immediately connect it with the keywords 'Cooling Effect' and 'Higher Acidity.' Remember the '0.6°C per 100m' rule to solve even the most challenging temperature-related questions.
