Jittery Joe’s

Jittery Joe's is a rapidly growing coffee chain based in Athens, and we get to explore their world via the fast-growing field of food science. We interview Roaster Master Charlie Mustard and learn the intricacies of what goes into making a great cup of “joe." It turns out there’s a lot of math and science behind it. So Teachable Moments focus on where coffee is grown, how huge this industry really is, and exactly how caffeine affects the body.
