Answer:
Yeasts are the main fermentor and alcohol producer in the production of wine, beer and other alcohol drinks.
The main yeast species used is Saccharomyces cerevisiae. It ferments the sugars, coming from different sources, e.g., grapes for wine, barley for beer, to alcohol and carbon dioxide.
Both wild and cultivated strains are used. The species or strains used in the fermentation play an important role in giving the final taste properties of the drink.
