Steve Byers
CEO, Byers Brewing

Steve grew up in the rural parts of Indian Creek School district. After middle school, he moved in with his father in Sycamore, IL. Graduating in 2006, he didn't know what to do for work or school. After an unsuccessful semester at NIU, he worked for a small family business in Sycamore called Soft Water City. Quickly he started taking classes at Kishwaukee College and eventually moved down to Illinois State University. He settled into a biology education major. Graduating in 2013 with one child, he and his wife Megan moved back to DeKalb. After subbing for a year, he landed a full-time position at Huntley Middle School in DeKalb. After five years of teaching, he moved to DeKalb High School.

Byers Brewing Company began as the Free Range Beer Company with a friend Byers homebrewed with. After years of talking about the concept of starting a business, the idea began to take shape; although his friend had decided not to be a part of the business. With just equity in their home, Steve and Megan were able to acquire financing to open the business. Delays from the equipment manufacturer nearly cost too much, even before the doors officially opened. Eventually the pieces came together and the business was launched.

The Byers Brewing Company is a nanobrewery. Each batch of beer is only about 93 gallons. The business plan was to keep beer as fresh as possible and focus on sales in the taproom in order to maximize margins. Eventually, Steve would like to compete in national brewing competitions. Brewing achievements would not only bring customers to the brewery but also help to reinvigorate DeKalb's downtown area.
