Coffee dates back to the 9th century. Goat herders in Ethiopia noticed their goats seem to be “dancing” after eating berries from a particular shrub. They reported it to the local monastery, and a monk made a drink out of it. The monk found out he felt energized and kept him awake at night. That’s how the first coffee drink was born.
