Gahahe washing station is located in Gahahe, Kayanza Commune in Kayanza province. The washing station lies at 1,805 metres above sea level. The washing station is equipped with 10 fermentation tanks, 4 cherry selection tables, 2 soaking tanks and a drying field with 180 drying tables, and 18 pre-drying tables and can process up to 750 metric tonnes of cherry per season.
During the harvest season, all coffee is selectively hand-picked. Most families only have 200 to 250 trees, and harvesting is done almost entirely by the family. Greenco knows that even small distances can be time consuming and expensive to travel for smallholder farmers, and they know that receiving cherry immediately after harvest is crucial to quality. Therefore, smallholders can bring their cherries either directly to a washing station or to one of the 12 collection sites situated throughout growing areas. Farmers are paid the same for their quality cherry regardless of where they bring their cherries. In this way, farmers are not disadvantaged due to their location and Greenco bears the cost of transport to stations.
Quality assurance begins as soon as farmers deliver their cherry. Cherries are wet processed under constant supervision. The pulping, fermentation time, washing, grading in the channels and a final soaking is closely monitored. All cherry is floated in small buckets as a first step to check quality. Greenco still purchases floaters (damaged, underripe, etc) but immediately separates the two qualities and only markets floaters as B-quality cherry. After floating, the higher quality cherry is sorted again by hand to remove all damaged, underripe and overripe cherries.
After sorting, cherry is pulped within 6 hours of delivery. The coffee is then dry fermented for up to 12 hours and then washed in clean mountain water for 12 to 24 hours.
Parchment is then soaked for an additional 12-18 hours before being dried on raised beds for 2 to 3 weeks.
