So, where did coffee come from and how did it become so popular? According to legend, a sixth-century Ethiopian goatherd named Kaldi discovered his goats frolicking from one coffee shrub to another. He recognized that the coffee berries they were eating had a stimulating effect, and he began to experiment with the seeds. A century later, brewed coffee emerged in Arabia and the popularity of coffee grew at an exponential rate.

Today, over 400 billion cups of coffee are consumed each year. It is a world commodity that is second only to oil. Don't forget to take a coffee break (or two) to celebrate this historical and important beverage!
