Most coffee trees in Burundi are Red Bourbon for reasons of quality. Because of the increasingly small size of coffee plantings, aging rootstock is a very big issue in Burundi. Many farmers have trees that are over 50 years old, but with small plots to farm, it is difficult to justify taking trees entirely out of production for the 3 to 4 years it will take new plantings to begin to yield. In order to encourage farmers to renovate their plantings, Greenco purchases seeds from the Institut des Sciences Agronomiques du Burundi (ISABU), establishes nurseries and sells the seedlings to farmers at or below cost. Farmers can also obtain organic fertilizer made from composted coffee pulp at the washing station.

Despite the ubiquity of coffee growing in Burundi, each smallholder produces a relatively small harvest. The average smallholder has approximately 250 trees, normally in their backyards. Each tree yields an average of 1.5 kilos of cherry so the average producer sells about 200-300 kilos of cherry annually.

During the harvest season, all coffee is selectively handpicked. Most families only have 200 to 250 trees, and harvesting is done almost entirely by the family.

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 are all closely monitored. All cherry is floated in small buckets as a first step to check quality. After floating, the higher quality cherry is sorted again by hand to remove all damaged, under ripe and over ripe cherries.

After sorting, cherry is pulped within 6 hours of delivery. The machine can process up to 3 tons of cherries per hour. During pulping, cherry is separated into high- and low-grade by density on a Mackinon 3-disc pulper outfitted with an additional separation disk. Coffee is then fermented in water from a nearby stream for 10 to 12 hours, depending on ambient temperature. A small sign on the fermentation tank keeps track of each lot. The sign mentions the washing station name, date of cherry purchase, grade of the bean and the time when fermentation began. Trained agronomists check the beans by hand regularly to ensure fermentation is halted at the perfect time. The station workers trample the parchment for 30 minutes in the fermentation tank. This trampling process helps to remove mucilage from the parchment.

Following fermentation, coffee is run through washing and grading canals. As the beans flow through, wooden bars that are laid across the canal prevent beans of specific densities from passing through. These bars are spaced across the channel. While the first blockade stops the most-dense beans, the next is arranged to stop the second most-dense beans, and so on. In total, the channel separates beans into seven grades according to density. After washing, this parchment is poured onto wooden trays or nylon bags and carried to the drying tables, each in its separate quality group. Each tray and nylon bag of parchment keeps its traceability tag with all info.

Parchment is laid on raised beds to dry. Pickers go over the drying beans for damaged or defective beans that may have been missed in previous quality checks. Usually, each table holds 800kg of parchment. In the peak of the season, the maximum load for a table is 1000kg. Each table has its traceability tag with the lot info. Parchment is left to dry from sunrise to sunset and is covered with a sheet during the evening or when it rains. During this time, parchment is turned regularly. The moisture level is carefully monitored and any parchment with visual defects is removed.

Greenco, a company that oversees and structures washing stations in Kayanza province of Burundi, gives washing stations and producers support all along the production chain. They started their work in 2015, and have dominated all Cup of Excellence competitions in Burundi ever since. Currently, Greenco has 13 washing stations all located in Kayanza in the north of Burundi. The producers receive support from the Greenco CWS managers, who are all agronomic engineers. Greenco’s overall impact through these 13 central washing stations (CWS) extends to over 15,210 coffee producing households.

Another socio-economic challenge that Greenco addresses is youth unemployment. The national youth unemployment rate is almost 50%. At Greenco, young graduates receive a decent salary and benefits (house, motorbike, healthcare) as well as real career prospects.
