Coffee's discovery dates back to the 9th century in Ethiopia. Legend tells of a goat herder named Kaldi who noticed his goats becoming energetic after eating berries from a certain tree. Kaldi tried the berries himself and experienced a similar energy boost – thus began humanity's love affair with coffee.
Fun Fact: Coffee was once considered so powerful in the Arab world that it was banned in parts of the Middle East in the 16th century for its stimulating effects!
