PB stands for peaberry - Normally each coffee berry contains two seeds (beans) that develop with flattened sides, but sometimes only one of the two seeds is fertilized, and that seed develops without anything being able to flatten it. This oval (or pea-shaped) bean is known as peaberry. Typically, about 5% of all coffee beans harvested have experienced this specialty.

Peaberries thus occur naturally in most coffees and are removed from the harvest as part of the manual sorting process because they behave differently during roasting, but with certain batches, as in this case it is possible to collect enough to sort separately. Peeberry is perceived to have higher acidity, be more complex and sweeter than ordinary coffee beans from the same harvest - which is believed to be due to the fact that only one bean gets all the nutrition instead of two. However, not enough research has been done in the area to claim that this is the case.

However, the PB this year were relatively small in volume from Kenya, so this party consists of coffee from hundreds of small farmers from the area around the washing stations of the Thirikwa Cooperative Farmers Society. The team at the washing station sorts the coffee berries before they go into production. The coffee is processed with dry fermentation, before being washed and graded in channels to be dried on raised beds.

The Kirinyaga region is located on the slopes of Mount Kenya and together with the neighbouring region of Nyeri, it is known for coffee with some of the most intense and complex flavours in the world. The region consists mainly of small farmers, each with about 100 trees. The farmers are organized in cooperative associations that act as umbrella organizations for the factories (washing stations), where the small farmers deliver their coffee cherries for processing.
