Kaldi, a goatherd in what is now Ethiopia, noticed the vigour in his animals when they nibbled the berries of a certain bush, and tried one himself. He was so excited by the results that he picked a basket of the berries and brought them to his village. A monk declared the effects to be the work of the devil, and threw the berries into the fire, but the roasting smell was so delicious that he changed his mind, and placed the charred beans in a jug of hot water, making the first pot of coffee.
This is supposed to have happened in the 9th Century CE, but as the story did not appear until around 800 years later, and there is no other written history of coffee until the 16th Century, it seems unlikely.
An experimental project with Workshop Coffee, wool rib socks are dyed with finely ground coffee which has not passed through Workshop’s quality-control processes for drinking, so would otherwise be wasted.
