Coffee, brewed from beans, is a popular drink across the entire world. Coffee beans are harvested from cherries grown from the genus of plants known as Coffea. There are over 500 genera and 6,000 species of tropical coffea trees.
A coffee cherry's outer skin is the exocarp, beneath it a thin layer of pulp known as mesocarp, then a slimy layer called parenchyma. The beans within this are covered in a thin layer named the endocarp. Inside the endocarp are two beans, usually positioned next to each other, divided by a membrane called the spermoderm.
Although the availability of coffee is ubiquitous, coffea trees can only be grown in certain climates. The most effective places to grow coffee are in tropical or sub-tropical environments at high altitudes. Because of this, distinct places in the world are prime for coffea cultivation; Brazil, Columbia, India, Indonesia, Mexico, Puerto Rico, and Vietnam are the top coffea growing and exporting countries.
