Question:
Wines are prepared from:
Wines are prepared from:
Show Hint
Grapes contain glucose and fructose, which yeast can ferment directly into ethanol and carbon dioxide without any complex pre-treatment.

- Vegetables
- Cereals
- Grapes
- Millets
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Wine is an alcoholic beverage produced through the fermentation of fruit juices.
• Fermentation is carried out by yeast, primarily Saccharomyces cerevisiae.
• Substrates must contain high levels of fermentable sugars.
Step 1: Identifying the primary substrate.
While many fruits can be used, grapes are the standard industrial substrate for wine. Grapes have the perfect balance of sugar, acid, and nutrients for yeast.
Step 2: Analyzing other options.
Cereals and millets are typically used to produce beer or spirits like whiskey. This process requires "malting" to convert starch into sugar first.
Step 3: Conclusion.
Unless specified otherwise, the term "wine" globally refers to the fermented juice of grapes. Final Answer: (C)
