What is yeast made of?
What is yeast. Yeast is a microorganism, made up of just a single cell. Yeast cells grow in a very different way and a lot faster, than animals (like humans) do.

Saccharomyces cerevisiae, also known as brewer's or baker's yeast, has been a key ingredient in baking, winemaking, and brewing for millennia. It derives its name from the Latinized Greek meaning “sugar fungus” because it converts sugars and starches into alcohol and carbon dioxide during the fermentation process.
How is fresh yeast made?
