Do you know the origin of Coffee?
Ethiopia, a long time ago..
Kaldi, a shepherd, used to herd his goats every day. One day the goats started eating berries and chewing leaves from an unusual plant. It was a Coffee plant. The same night, the goats, instead of sleeping, couldn’t stop wandering endlessly around. Kaldi was both annoyed and shocked. He spent all the night thinking about an explanation. He finally thought the effect could be caused by the mysterious berries. He therefor tried toasting and grinding some of them, making an infusion to drink. He was right.
Coffee was considered an excitant for centuries.
