To sum up, peaberry is not a coffee variety. It is a special form of coffee bean itself. It has only one rounded bean as compared to two regular beans. In theory, we can harvest Arabica, Robusta and excelsa peaberry. The coffee is often marketed as a specialty due to its scarceness and limitation. In Vietnam, it has other name such as Culi coffee. The Culi coffee is considered as Vietnamese premium coffee bean and has expensive prices. Peaberry is rich in aroma and taste as well as higher in caffeine content.
