The Bean Belt: (n.) the nickname for the area where coffee grows.
Coffee plants are fickle things. They’re only able to grow in certain environmental conditions, and the certain conditions they like are only found between the Tropic of Cancer and the Tropic of Capricorn. That means the middle of the globe has a delicious coffee fruit belt around it, with coffee growing happily in diverse places like Mexico, Ethiopia, Yemen, Vietnam. Coffee likes moderate sunshine and ample moisture, conditions found in mountainous regions – hence many high-quality coffees being grown at higher altitudes.
