Mocha coffee bean
The Mocha coffee bean is a variety of coffee bean originally from Yemen.
The Mocha coffee bean is derived from the coffee species Coffea arabica, native to Ethiopia. In appearance they are very small, hard, round with an irregular shape and olive green to pale yellow in colour.
The Mocha coffee bean has a distinct flavor. Due to the similar name, it is sometimes being confused with a chocolate flavored coffee. In the 17th Century, the Mocha coffee bean was available only from the city of Mocha, Yemen and it was shipped only already roasted to prevent propagation. The Mocha coffee bean was so expensive that in 17th Century France, only the royal family could afford it. The beans were available outside of Yemen until 2012, when sanctions imposed by the USA prevented legal export.
The Mocha coffee bean should be roasted light in order to preserve the special flavor.
