The Biology of Brewing

Want to learn more about brewing? Are you thinking about entering into the fermentation industry, or maybe just starting up a small home brew experiment? Then this four video series will introduce you to how the science of biology plays a central role in the process of brewing.

How Does Biology Relate to Brewing?

In this first video, we take you on a quick tour of the brewing process to introduce the major stages of the brewing process and the role of some key biological players – namely yeasts and barley.

The Biology of Malting

Malting is the first step of the brewing process, and it involves the activation of the enzymes that are naturally found in the barley grains. Learn more about this process in the animation below

The Biology of Mashing

Mashing is the process by which the activated enzymes from the malting process break down complex carbohydrates (such as starch) into simple sugars. Learn more about this process in the animation below:

The Biology of Fermenting

The final step of brewing introduces the role of yeast – the organism that converts the simple sugar into the alcohol present in beer. Learn more about why the yeast performs this process in the animation below.


All of the videos above were built by biology professor Jason Carlson to show the relevancy of science in his classroom to topics such as fermentation. If you like these types of videos, please drop us a note below to let us know of what other topics you would like covered in the future.
