Because a coffee flower typically contains two ovules (the structures in a flower's ovary that develop into seeds after fertilization), normal development of a coffee cherry will generally result in two seeds within a coffee cherry. Each seed, or ‘coffee bean', will exhibit the classic morphology we’re familiar with: one flat side with a center crack and one rounded side. Occasionally, however, a coffee cherry will have just one perfectly round seed instead of the normal two. These anomalous seeds are referred to as peaberries, given their resemblance to the legume, and are often separated during milling due to their smaller and rounder screen size. Aside from possible genetic mutations, a potential cause for this is the failure of one of the two ovules to be fertilized. As a result of this failure, one of the endosperms of one of the two ovules fails to develop, leaving sufficient space for the remaining one to develop a robust endosperm with a fully round pea-like shape.
