During the process of turning grape juice into wine, what is the name of the central step in which yeast converts the sugar in the juice into alcohol?
- A. Harvesting
- B. Crushing
- C. Fermentation
- D. Bottling
Critical Answer & Explanation
Answer: C. Fermentation Explanation: Fermentation is the magical stage where grape juice finally becomes 'wine.' Yeast consumes the sugar found within the pulp and converts it into alcohol, carbon dioxide (CO2), and heat. Harvesting and crushing are merely preparatory steps; it is only through fermentation that the liquid officially becomes wine.

Expert Mastery Theory
There are four key journeys that a grape takes to become wine: 1. Harvesting: Grapes are picked at the exact moment their sugar and acidity levels are perfectly balanced. 2. Crushing: The grape berries are gently broken to release their juice. 3. Fermentation: Either by adding yeast or using naturally occurring ones, the sugar is converted into alcohol. 4. Maturation: The wine is stabilized and allowed to develop additional flavors in either stainless steel tanks or oak barrels. (e.g., Oak maturation provides Vanilla and Toast flavors)
Pass-Guarantee Tip
[Trap]: Do not assume that "All wines must undergo maturation in oak barrels." Many white wines that emphasize freshness are briefly stabilized in stainless steel tanks and then bottled immediately. [Tip]: In the exam, if you spot the phrase 'Convert Sugar into Alcohol', always select 'Fermentation' as your answer. This formula is the cornerstone of all wine knowledge.
