The coffee bean

Coffee beans are inside the red fruit of Coffea. They are green in color and turn a rich brown hue after roasting.

There are about 124 Coffea species, and most flavors remain unknown. Two species are mainly used for our coffee: arabica and canephora, known as robusta. Arabica costs more and fills specialty cafes, while the more common robusta is used for instant coffees and some espressos.
