A peaberry coffee bean occurs when the coffee cherry develops only one bean instead of the normal two. This creates a rounder, smaller bean. Approximately 2-3% of all coffee cherries produce a peaberry bean.
Does a peaberry taste different? In my opinion, yes. Although subtle, peaberries seem to have a certain heightened focus and brilliance. A special flavor zest that I, and many others, find very appealing.
Taste: We roast our Tanzanian peaberries to a medium point that best shows off their intense fine qualities. The flavor in the cup is fruity with retained sweetness. At this roast level the Tanzanian character stands out. And shares some of the fine wine character found in quality Kenya coffee.
