What is Yeast?

Yeast, saccharomyces cerevisiae, is a single-cell organism that is apart of the fungus kingdom. When fermented, it converts sugar and starch into carbon dioxide and alcohol. Carbon dioxide helps baked good rise.

To grow, yeast needs to eat and digest food. When baking, the yeast will eat the sugar in the dough, creating carbon dioxide. Because the dough is sticky and stretchy, the carbon dioxide cannot get out, making the dough rise.

There are actually 1,500 species of yeast and can reproduce quickly. Yeast is not only just related to food. It can cause infections and cure infections too!

Even though it is weird to think about, yeast is alive and grows quickly. But without it, we would not be able to have breads, muffins, or any other baked good that needs to rise.

Baker’s yeast is sort of an umbrella term for dry yeast, fresh yeast, and natural yeast. Each use yeast to bake bread.

Natural yeast is the very basic, broken down yeast. You go through the fermentation process on your own with yeast, water, and flour. People will use natural yeast over other types because they find it gives whatever they are baking a better texture.
