Question

Why are yeast cells used to produce wine?

Answer 1

Yeast cells in wine production:

1. Yeast aids in the fermentation process of making wine by converting the sugar in grapes into alcohol and carbon dioxide.
2. Saccharomyces cerevisiae is the most popular yeast used in wine production.
3. Its propensity to ferment with consistency and vigor, tolerance for relatively high alcohol and sulfur dioxide concentrations, and ability to thrive at typical wine pH levels of 2.8 to 4 have all contributed to its rise in popularity.
4. The use of yeast in winemaking is the key distinction between wine and grape juice.
5. Without oxygen, yeast converts the carbohydrates in wine grapes into alcohol and carbon dioxide as part of the fermentation process.
