How Humanity Got Hooked on Coffee

We've all heard the story about the discovery of coffee, when an Ethiopian goat herder noticed his goats frolicking energetically after consuming coffee beans. Once the goat herder shared his discovery with the local monastery, there was no turning back. We don't know whether there's any truth to the legend, but we do know that coffee consumption began in Ethiopia. It was consumed in several ways. The more fascinating story is how the beverage took over the world, and that history is documented. This TED-Ed lesson from Jonathan Morris follows the rise of coffee as both its flavor and its caffeinated effects got the entire world hooked.
