Yeast is a tiny living organism that is used in brewing beer. It is responsible for a process called fermentation, where it eats sugars and produces alcohol and carbon dioxide. This is what gives beer its alcoholic content and bubbly texture.
When making beer, yeast is added to the mixture of malt, hops, and water called wort. The yeast eats the sugars in the wort and produces alcohol and carbon dioxide as byproducts. The alcohol gives the beer its alcoholic content, while the carbon dioxide makes it fizzy.
The type of yeast used in brewing can affect the flavor and aroma of the beer, so brewers choose the yeast strain that will create the desired taste. Yeast is an essential ingredient in making beer, and without it, we wouldn't have the delicious beverage we know and love.
