Practice Question

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. Ferments with skins and seeds for a long time to extract strong tannins.

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 Exam 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.
