This coffee was produced by 43 smallholder producers who farm coffee in the high hills surrounding Remera washing station, located in the Kamageri Sector of Nyamagabe District, in Rwanda’s Southern Province. The farmers are members of the Kawanziza Farmer’s Group, a small association of producers who deliver coffee to Buf Coffee company, who own and manage Nyarusiza along with three other washing stations.
Most washing stations in Rwanda receive cherry from hundreds (and sometimes thousands) of farmers who own very small plots of land. Separation of such tiny lots is expensive and impractical, so the large majority of coffees are processed as a mixed lot from multiple producers. Typically, lots are separated as day lots (ie. cherries that were all picked on the same day) rather than by a single farm or producer group.
The farmers who make up the Kawanziza group come from a nearby village called Gasaka. Recently they banded together and made the decision to process and market their coffees separately as a smaller, more selected lot. The group also provide each other with invaluable support, by sharing resources and labour during the busy harvest period. They named their association Kawanziza, which roughly translates to ‘beautiful coffee’ in the local Kinyarwanda language.
To distinguish their coffee and ensure it is processed separately, the producers have organised to deliver cherry to the washing station on certain days of the week. Selling their coffee as a separate lot allows them to directly benefit from any higher prices paid specifically for their coffees (rather than these profits being shared equally amongst all contributing producers) and results in a higher income to support their families. This creates an effective incentive for the farmers to work as a collective towards achieving the very best quality, and we think the results are evident in the complex and clean profile of their coffee!
HOW COFFEE IS PROCESSED BY BUF COFFEE
- The ripe cherries are picked by hand and then delivered to the washing station either on foot, by bike, or by trucks that pick up cherries from various pick-up points in the area.
- Before being pulped, the cherries are deposited into flotation tanks, where a net is used to skim off the floaters (less dense, lower grade cherries). The heavier cherries are then pulped the same day using a mechanical pulper that divides the beans into three grades by weight.
- The beans (in parchment) are then dry-fermented (in a tank with no added water) overnight for 8–12 hours. They are then sorted again using grading channels; water is sent through the channels and the lighter (i.e. lower grade) beans are washed to the bottom, while the heavier cherries remain at the top of the channel.
- The wet parchment is then soaked in water for around 24 hours, before being moved to pre-drying beds where they are intensively sorted for around six hours. This step is always done while the beans are still damp because the green (unripe) beans are easier to see. It is also always done in the shade to protect the beans from direct sunlight (which they have found helps to keep the parchment intact and therefore protects the bean better).
- The sorted beans are finally moved onto raised African drying beds in the direct sun to dry slowly over 10–20 days. During this time the coffee is sorted carefully for defects and turned regularly to ensure the coffee dries evenly. It is also covered in the middle of the day when the sun is at its hottest.
- Once at 11–12% humidity, the coffee (still in its parchment) is stored in the washing station’s warehouse in carefully labelled lots until it is ready for export. The coffee is then sent to Buf’s brand new dry mill, Ubumwe (built 2017), to be dry-milled. Here the parchment is removed, and the beans are sorted again by hand and using machinery to remove any physical defects. This is done under the watchful eye of Edouine Mugisha, who has worked with Buf since 2011. Having control over the milling of the coffee means that Buf has greater control over the quality of sorting and processing from cherry delivery right through to export.
