Yeast has the ability to enzymatically convert simple sugars into Ethyl alcohol and Carbon dioxide.
Normally this is a two step process. The first step is the aerobic budding and multiplication phase where the yeast grows in numbers. The second is an anaerobic phase where the actual fermentation takes place.
This is true for both baker's yeast (to leaven breads) and brewer's yeast (for alcohol production). Yeasts are single-celled (unicellular) fungi, not bacteria.

Yeast is simply a bunch of bacteria (scoop up some dust, and you will have a weak yeast). It multiplies by feeding on sugar.

C6H12O6 (glucose) â2C2H5OH + 2CO2
In the absence of oxygen, fermentative yeasts produce their energy by converting carbohydrates(glucose) into carbon dioxide and ethanol (alcohol) or lactic acid.

Yeast is a plant. It "digests" sugar and converts it to alcohol.

C6H12O6 ---> 2C3H6O3 + 2 ATP
