What is yeast?

Yeast is a tiny plant-like microorganism that exists all around us - in soil, on plants and even in the air. It has existed for so long, it is referred to as 'the oldest plant cultivated by man.' The main purpose of yeast is to serve as a catalyst in the process of fermentation, which is essential in the making of bread.

What is the purpose?

The purpose of any leavening agent is to produce the CO2 gas that makes bread rise. Yeast is no different. Yeast does this by feeding on the sugars in flour, and producing a waste product carbon dioxide in the process. With no place to go but up, this gas slowly fills the bred with tiny air pockets that gives the bread its fluffiness. A very similar process happens as bread rises. Once the bread has baked, this is what gives the bread its airy texture.
