Brazil Jazblu Peaberry –
What Is a Peaberry & How Does It Form?
Inside a regular coffee cherry with no defects, you’re expected to find two seeds, with their flat fronts facing inwards, and their round backs facing outwards. The seeds of the coffee cherry are what is removed, processed, and roasted for consumers to enjoy i.e. coffee “beans”.
Peaberries are estimated to make up to around 5–10% of a harvest. They occur as a result of a natural mutation, or defect, inside a coffee cherry, where one ovule fails to pollinate. This results in extra space for the single developing seed. Within this space, a larger and rounder seed grows inside. This is a peaberry.
