Today’s beer video is an interview with Mark Morvant, professor of chemistry at the University of Oklahoma , by the local newspaper blog The Thirsty Beagle. Morvant is teaching a free online course on The Chemistry of Beer. The class started January 13, but apparently you can still participate and catch up if you hurry and register soon. So far, over 7,000 people have signed up for his class. Watch the video below to see if it’s for you.
