Sourcing Details: The bulk of Rwanda’s coffee processing is
based on a centralized washing station system. The harvest starts on small family owned farms where coffee is cultivated on just a few acres of land usually intercropped with soy beans.
These farmers deliver their harvested cherries to a modern washing station, which alleviates the expense and risk of processing themselves. Processing Details: This particular lot was produced at a washing station in the Nyarugurui District run by Impexcor ltd, which was established in 2018.
A select group of 170 local coffee farmers harvest and deliver cherries to the Nyaruguru washing station.
Processing at the Nyaruguru washing station includes hand sorting and floating cherries to remove damaged or underdeveloped coffee.
Next cherries are depulped and fermented. Once the fermentation is complete the parchment is soaked in fresh water between 18-24 hours to halt fermentation and stabilize the moisture content of the batch. After the soak, the parchment is washed once again, this time in grading channels—long shallow concrete channels with water flowing through—which allows the parchment to naturally separate by density. From here, each separate density grade is moved to pre-drying tables to be hand-sorted for imperfections and gently dried to the touch. After the hand-sort is complete, the parchment is then moved to fully-exposed drying tables to finish drying, a process that takes between 14-21 days depending on the climate.
