Solution(By Examveda Team)

Yeast is employed in the preparation of Wine.
The role of yeast in winemaking is the most important element that distinguishes wine from fruit juice. In the absence of oxygen, yeast converts the sugars of the fruit into alcohol and carbon dioxide through the process of fermentation.
The more sugars in the grapes, the higher the potential alcohol level of the wine if the yeast is allowed to carry out fermentation to dryness.
