​Microbiology for Brewers

​Brewing Microbiology and Microscopy Course

This hands-on course, completed either in a one and a half day or three day format, provides brewers with the essential techniques and protocols for managing yeast and bacteria in the brewing process. Ample time in the class allows participants to practice the techniques demonstrated and for viewing their results. No prior experiences necessary. Class size is small, limited to 12, allowing for personalized attention to each participant. Class meets in a fully equipped microbiology lab at the University of Wisconsin-Stevens Point. This is not a course on how to brew beer.

Target Audience

Commercial craft brewers who are getting more involved in microbiological aspects of quality control, as well as home brewers who want to better understand aspects of production.

About the Instructor

This course is instructed by Terese Barta, Ph.D., Department of Biology, at UW-Stevens Point. Terese has been teaching microbiology in the UW system since 1994. As a way to introduce her bacteriology students to a practical application of the field, she took up home brewing, and has been an avid home brewer ever since. While at the University of Wisconsin-Marathon Center, she began outreach to the community by teaching home brewing courses, and was instrumental in creating the Bull Falls Brewers, a home brew club in Wausau, Wisconsin.

In 2012, at the University of Wisconsin-Stevens Point, after providing consulting work to a local microbrewery, Terese found a need for professional development opportunities in the brewing industry.  She developed the Microbiology for Brewers program that year to target professionals in the brewing industry as well as home brewers.
