A coffee bean is part of a seed from the cherry of a coffee tree. Generally, the seed consists of two halves, each with one flat side and one rounded side. Occasionally, a cherry will contain a single rounded bean, commonly referred to as a peaberry. The bean is surrounded by a thin skin, referred to as parchment[1]. The bean itself often has a greenish hue to it prior to being processed and roasted.
