Matt McCarroll pours out hops Tuesday at Windy Hill Hops farm and brew shop in Murphysboro. McCarroll, an associate professor of chemistry and biochemistry at SIU, owns Windy Hill Hops and teaches a chemistry of brewing class on campus, which allows students to learn the history and science of brewing beer. “Before we opened, a lot of home brewers had to either drive to St. Louis or order their hops, grains and yeasts online,” McCarroll said. “But now we allow them to come in and smell and even taste the grains before purchasing so they get a better idea of what they are getting.”
