Shipping January 16: Rwanda Nova PB
Flavours of peach iced tea, mandarin
This coffee comes from the Nova Coffee washing station in the Gicumbi district of Northern Rwanda.
The washing station was previously operated as part of a cooperative, but there was little invested in the washing station or the cooperative itself to increase quality and their capacity.
But Agnes Mukamushinja saw the potential of the washing station, and purchased it in 2013 with her husband, and renamed the washing station to be Nova Coffee.
What happens at the washing station?
Farmers deliver their cherry at the reception area of the washing station, where it will be checked to make sure the farmer has picked and sorted correctly. In cases where further sorting is required, the farmer will be asked to do so, then it’s weighed and moves on to pulping.
The cherry are placed in a tank prior to pulping where ‘floaters’ are removed, using simple technique: over-ripe and undeveloped cherries rise to the surface of the tank, ripe and green ones are dense and sink. The unripe or over-ripe are processed separately, and sold as as lower grade coffee.
From here the coffee is pulped and then fermented. Rwanda’s climate through most of the harvest season is relatively cool, which helps in controlling the fermentation process. After this the parchment is graded and washed in channels, it is separated into two grades based on density before being soaked under clean water in tanks for up to 16 hours.
The parchment is initially taken to shaded pre-drying tables, and while the parchment is still wet another round of sorting is done by hand as it is much easier to spot defects at this point. The parchment is dried on African drying beds for up to 15 days, and covered by shade cloth during Rwanda’s intense midday sun, or to protect it from moisture during any rain and at night.
Once dried, it’s packed in bags and shipped for export.
What’s with the PB?
If you take a closer look at these beans, you’ll notice something unusual: the beans are a little smaller and more rounded in shape compared to the usual half-sphere. This unusual bean shape is called a Peaberry, often shortened to PB.
Normally a coffee bean splits in two during development giving it the typical shape, but up to ten percent of crops can develop as peaberries.
Other than in Kenya, peaberries are not traditionally picked out when processing and traded as a separate lot, but it sometimes happens when there’s an exceptionally great harvest.
The last time we shared a peaberry was a year ago: Nyamasheke PB, from Rwanda’s Western Province.
Most Rwandan farmers plant subsistance crops, with only ten percent of farmers growing coffee — but it’s already become a significant crop for trade, generating up around 40% of all export revenue.
Rwandan coffee
Nova also works with the Rwanda Trading Company to increase efficiency and quality.
The Rwandan Trading Company owns and manages a small number of washing stations in Rwanda, and also works with many other washing stations and independent farmers throughout the country to help improve production, quality control and market their coffees. RTC was established in 2009 as a vehicle for social impact and offers financial literacy, agribusiness management and agronomy training programs to its partners to increase yield and keep them operational, profitable and healthy.

Sample Coffee is a small coffee roaster in Sydney, Australia. We celebrate great coffee in our cafes and share a different coffee every two weeks with our coffee deliveries, telling the story of each coffee, just like this one from Rwanda.
