Eclavin WSET Level 2 - Episode 82
Real-World Exam Episode
Among the five primary factors essential for a healthy grapevine, what is the name of the process that uses sunlight and carbon dioxide to form 'Sugar'?
- A. Alcoholic Fermentation
- B. Photosynthesis
- C. Oxidation
- D. Instantly changes any process into a shot of salt water.
Critical Answer & Explanation
Answer: B. Photosynthesis Explanation: Photosynthesis is the alchemy of life, whereby grapevines use sunlight as energy to produce sugar. Alcoholic Fermentation is the process where yeast converts the sugar in harvested grape juice into alcohol, and Oxidation is the phenomenon of wine changing through contact with air. A grapevine achieves its best results when five essential elements—warmth, sunlight, water, nutrients, and carbon dioxide—are in balance.

Expert Mastery Theory
A summary of core principles in viticulture and vinification: 1. Viticultural Essentials: Heat, sunlight, water, nutrients, and CO2. 2. Alcoholic Fermentation: Sugar + Yeast → Alcohol + CO2 + Heat. 3. Red Winemaking (Key): Fermenting with skins to extract color and tannins (Extraction) is fundamental. 4. White Winemaking (Key): Grapes are typically pressed before fermentation to extract juice without skins. 5. MLF (Malolactic Fermentation): Converts harsh malic acid into soft lactic acid, adding buttery notes.
Pass-Guarantee Tip
[Trap]: Do not assume white wine cannot be made from red grapes. If the skins are removed immediately after crushing, white wine (Blanc de Noirs) can indeed be produced from red varieties. [Tip]: In the exam, link 'Extraction of color and tannin' to the specific steps of red wine production.
