Assertion : Microbes especially yeasts have been used for the production of beverages like wine, beer, whisky, brandy or rum.
Reason : The yeast Saccharomyces cerevisiae is used for bread-making and commonly called baker’s yeast.

The A and R both are true but R is not the correct explanation of A .

The correct answer is Option (3)- The A and R both are true but R is not correct explanation of A .

Microbes, particularly yeasts, have played a significant role in the production of various beverages for centuries. Yeasts, especially the species Saccharomyces cerevisiae, have been used extensively in the fermentation process to produce alcoholic beverages such as wine, beer, whisky, brandy, and rumcommonly known as brewer's yeast. The dough, which is used for making bread, is fermented using baker’s yeast (Saccharomyces cerevisiae). It is a versatile microorganism that can efficiently convert sugars into ethanol and carbon dioxide through the process of fermentation.

Depending on the type of the raw material used for fermentation and the type of processing (with or without distillation) different types of alcoholic drinks are obtained. Wine and beer are produced without distillation whereas whisky, brandy and rum are produced by distillation of the fermented broth.
