A coffee cherry is composed of an exocarp which is the external skin (red or yellow when the fruit is ripe), the mesocarp which comprises the mucilaginous flesh known as pulp and mucilage, and the endosperm which consists of two beans that contain a germ (embryo). Each bean is covered by a spermoderm called silverskin and is surrounded by parchment (endocarp). If one bean aborts, its place remains empty and the other one grows into a more rounded shape, called peaberry (Brando 2004).
