Little beans with big flavor. Peaberry beans are small coffee beans with a cleft in the middle. They have a richer flavor than typical oval-shaped coffee beans. This means that a cup of Peaberry Coffee will be full-bodied, flavorful and aromatic. These beans are grown on the slopes of Mount Kilimanjaro, a dormant volcano in northern Tanzania, where the fertile soil and climate provide perfect conditions for the coffee plants to thrive.
