Unroasted peaberry green coffee beans. Normally the fruit ("cherry") of the coffee plant contains two seeds ("beans") that develop with flattened facing sides, but sometimes only one of the two seeds is fertilized, and the single seed develops with nothing to flatten it. This oval (or pea-shaped) bean is known as peaberry. Peaberry beans are widely reputed to roast better than flat berries, being said to roast more evenly, because their rounder shape minimizes sharp edges and allows the berries to roll about the roasting chamber more easily, as well as because the alleged higher bean density may improve heat transfer in the roasting process. Peaberry coffee tastes different than coffee from normal beans from the same crop.

Can be used to make green coffee or roasted to individual needs.
