The Coffee Bean Wall Shows the Science and Color of Coffee

If you're vacationing in Orlando at the newly opened Cabana Bay Hotel (Universal Studios), you might accidentally run across some colorful science in the Starbucks there. They have a "coffee bean wall" that shows the progression of beans, from green to red (peeled) to light and dark brown (roasted less vs. more). It makes for a nice-looking wall but the science of coffee is behind it. Well, I don't know what's actually behind it because I haven't been there but maybe I'll fix that on a future vacation. For example, the dark-roast beans have less caffiene because the heat has burned the caffiene right out of them. [Thanks to Theme Park Insider for the photo tour that showed this.]
