How was coffee discovered?

"The Ethiopian legend says that Kaldi, a goat shepherd, noticed that his goats became very active and could not sleep at night after eating fruits from a certain tree. He then decided to try out the leaves of the bush and felt full of energy and excitement. Kaldi went to the Abbot of the monastery next to his pastures, holding some branches of the mysterious tree. After the Abbot heard the whole story, he decided to cook the branches to sadly get the bitterest drink he ever tried. He threw the pot into the fire and surprisingly smelled an exquisite aroma. The idea to get a drink out of the roasted "cherries" came to him, and this is how coffee, the drink, came to life. Soon, this finding was spread across the Arabian Peninsula, and it was then when the whole longer story started." http://www.maatouk.com/coffee.aspx
