Kibingo Washing Station
The Kibingo central washing station is in the commune of Kayanza in northern Burundi. The station itself sits 1,893 metres above sea level. The altitude of the farms in the neighboring hills that supply the washing station varies from 1,700 to 1,900 metres above sea level.
Kibingo serves 3,515 registered coffee growers, spread over 18 hills in the area. All producers registered at a Greenco washing station are organized in groups of 30 people, headed by a farm leader. This leader acts as a spokesman to facilitate communication and organization with the washing station.
The washing station is equipped with 10 fermentation tanks, 2 soaking tanks and a drying field with 165 drying tables and 4 pre-drying tables. Kibingo can process 750,000 kg of cherry per day.
At the washing station, farmers can obtain organic fertiliser from composted coffee pulp. To promote farm renovation, producers can get low-cost, subsidized coffee seedlings at the washing station. Each station has its own nursery for this purpose.
Kibingo CWS participates in a number of farmer outreach and support projects include a goat and pig project, Farmer Hub, strengthening cooperatives and distributing fertiliser and coffee trees.
All coffee trees in Burundi are Red Bourbon, which is tightly controlled by the government 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 product for the 3-4 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. At the washing station, farmers can also get organic fertilizer from composed coffee pulp.
Despite the ubiquity of coffee growing in Burundi, each smallholder producers a relatively small harvest. The average smallholder has approximately 250 trees, normally in their backyards. Each trees yields an average of 1.5 kilos of cherry so the average producer sells about 200-300 kilos of cherry annually.
Harvest & Post-harvest
The average cherry buying price for Greenco in 2019 was significantly above average. CWSs make the first payment to farmers between 15-30 June. The second payment comes later in the summer. If the coffee wins a competition or sells for extremely high specialty prices, Greenco gives another payment approximately a year after the harvest 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 central washing station (CWS) or to one of the 10-15 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 CWS’s.
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, the beans are then transported directly to the drying tables where they will dry slowly for 3-4 weeks. Cherry is laid out in a single layer. Pickers go over the drying beans for damaged or defective beans that may have been missed in previous quality checks. The CWS is very strict about allowing only the highest quality cherry to complete the drying process. The beans are covered with tarps during periods of rain, the hottest part of the day and at night. On the table, the beans are dried to 11.5%.
Once dry, the coffee is then bagged and taken to the warehouse. Greenco’s team of expert cuppers assess every lot (which are separated by station, day and quality) at the lab. The traceability of the station, day and quality is maintained throughout the entire process.
Before shipment, coffee is sent to Budeca, Burundi’s largest dry mill. The coffee is milled and then hand sorted by a team of hand-pickers who look closely at every single bean to ensure zero defects. It takes a team of two hand-pickers a full day to look over a single bag. UV lighting is also used on the beans and any beans that glows—usually an indication of a defect—is removed.
The mill produces an average of 300 containers of 320 bags per year. Budeca is located in Burundi’s new capital city, Gitega, with a population of around 30,000 people. Since there are approximately 3,000 people working at the mill, mostly as hand pickers, this means that Budeca employs nearly 10% of the total population in Gitega for at least half the year (during the milling season). The same is true in the provinces of Ngozi and Kayanza, where Greenco and Bugestal are the first employers in the region during the coffee harvest season. This has an incalculable impact on a country like Burundi, with unemployment rates above 50%, especially in rural areas and among young people.
Coffee in Burundi
Coffee arrived in Burundi during the 1940s with the Belgian colonial government. The Belgian government, which oversaw and administered to the twin territory of Ruanda-Urundi between 1922 and 1962, made coffee growing mandatory during their rule. When the Belgian government withdrew, many stopped tending their trees because it was no longer compulsory. However, many also saw the economic advantages of continuing to grow coffee, and the industry became central to Burundi’s national economy.
The coffee industry in Burundi remained in the public sector until the start of the 21st century, when the government privatized some elements of the coffee chain. As a result of this relatively recent change, there are very few foreign companies involved in Burundi’s coffee sector.
Today, Burundi’s coffee industry is fueled by the 2 million smallholders producing more than 80% of the country’s total coffee export. To put this number in perspective, consider that the entire population of Burundi is only a little under 11 million people, so smallholder coffee producers comprise nearly a fifth of the total population. As Carlos Bobillo Barbeito, Managing Director at Greenco in Burundi says, “The country lives off coffee; everyone has someone who lives off coffee…It’s the backbone of the economy.”
All coffee trees in Burundi are Arabica. There was an attempt to introduce Robusta into Burundi with the establishment of a large plantation. The plantation was destroyed during a civil war and unrest near the end of the 20th century.
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.
Greenco works with young agronomy graduates to provide farmer training and manage washing stations. Young graduates are particularly well suited for the work with Greenco because they can all work with computer systems, greatly simplifying the flow of information between the washing stations and Greenco. Also, they have a fresh and systematic approach to coffee production and processing, with up-to-date knowledge about farming practices. The agronomists received additional training from the NGO Kahawatu Foundation on best agricultural practices (BAP). Off season, they provide agronomy assistance to the roughly 15,210 farmers who deliver cherries to Greenco CWS to prepare for the next harvest.
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.
Next to improving quality and productivity, Greenco strives to improve socio-economic and environmental conditions around the washing stations. All of their washing stations have UTZ and 4C certification. One of their focus points is building an efficient supply chain around the CWS. Greenco is buying 93% of its cherries directly from farmers via collection centres. This way, they improve farm-gate price to the producers.
In addition to providing training on farming practices, Greenco organises trainings for farmer groups about various social aspects. Coffee families learn about gender equality, financial planning, family planning and more.
Environmental stewardship is of paramount importance to Greenco. They have has equipped all washing stations with water treatment facilities and solar panels and batteries. The station has ponds to purify the wastewater from processing before flowing back in the river network. The solar panels provide energy for computers, lighting and smartphones.

Tipy a triky
1. Používajte čerstvo praženú výberovú kávu. Nechajte ju však postáť aspoň 7 dní po pražení, aby sa chuť kávy prečistila od chuti praženia. Po otvorení máte asi 2 až 3 týždne na spotrebovanie.
2. Kávu si nameľte na požadovanú hrúbku iba v množstve, ktoré okamžite spotrebujete.
3. Váženie všetkých parametrov: vstupné množstvo namletej kávy, čas od prvého kontaktu kávy s vodou až po dokončenie extrakcie a váha/množstvo použitej vody.
4. Brew ratio, teda pomer vstupnej a výstupnej váhy. Tento pomer sa líši pri rôznych kávach a aj pri rôznych metódach prípravy. My začíname pri brew ratio 1:15 a zvyšujeme alebo znižujeme pomer podľa chuti. Pri väčšine našich káv pri filtrovaní Hario V60 používame brew ratio 1:13 – 1:16. Čas extrakcie je 2:30 až 3:30 minúty. Postupne pridáme recepty na naše filtre na náš blog. Ak dodržíme dané parametre, TDS je v hodnote medzi 1,35-1,45% (mletie cez Mahlkonig EK43).
5. Voda a jej teplota pri príprave filtra. Na dobrý filter potrebujete kanvicu s husím krkom. Naozaj. Či si vodu zohrejete a potom prelejete je v podstate jedno, pokiaľ si viete udržať teplotu. Je však dôležité, aby ste boli schopný kontrolovať „flow“. Teplota by mala byť v závislosti na metóde prípravy od 94°C a vyššie. Ak nemáte chemický rozbor a dokonalú úpravu vody extrémne drahými zariadeniami, použite radšej balenú vodu. Hľadajte na fľaši 100 – 150 ppm.
6. Vždy pri bloomingu kávu pomiešajte. Nikto nevie naliať tak aby sa 100% kávy navlhčilo.
7. Pri nalievaní vody nemente výšku, z ktorej nalievate. Nalievajte smerom od stredu. Nikdy nenalievajte po stranách filtra.
Tipy a triky
1. Používajte čerstvo praženú výberovú kávu. Nechajte ju však postáť aspoň 7 dní po pražení. Chuť aj parametre espressa budú konzistentnejšie. Po otvorení máte asi 2 až 3 týždne na spotrebovanie. Namelte si kávu až tesne pred použitím.
2. Odporúčame použitie precízneho VST filtru. Velkosť je na Vás, my však používame 20g ridgeless VST, ale máme k dispozícii aj viac veľkostí (15g, 18g, 20g). Naked portafilter je preferovaný. Precízna sprcha (ako napr. Pesado alebo IMS) v espresso stroji sú tiež body navyše.
3. Tampovanie. Tamper musí byť plochý a dostatočne veľký. Odporúčame aspoň 58.4mm pre VST filtre. Nejaká pomôcka (napr. O.C.D. alebo Mahlgut) na rovnomernú distribúciu sú body navyše pre konzistentnú kvalitu medzi jednotlivými shotmi.
4. Váženie všetkých parametrov: vstupné množstvo namletej kávy, výstupná váha espressa a čas extrakcie.
5. Teplota pri príprave espressa. Ak viete teplotu nastaviť, odporúčame 93°C pre väcšinu káv, pri niektorých o stupeň menej. Tlak konštantne 8 – 8.5 baru.
6. Voda. Filtrovaná voda je základ. Ak máte stroj s nádobou môžete použiť niektorú z balených vôd s nízkym obsahom minerálov. Pre profesionálne použitie je to téma na veľmi dlho a to nie je úlohou tohto blogu.
7. Brew ratio, teda pomer vstupnej váhy kávy a výstupnej váhy nápoja. Tento pomer sa líši pri rôznych kávach, ale my začíname pri brew ratio 1:2 a zvyšujeme alebo znižujeme pomer podľa chuti. Pri väčšine našich káv sa nám osvedčil pomer 1:1.8 – 1:2.3. Čas extrakcie je od 28 sekúnd po 35 sekúnd. Postupne pridáme recepty na naše espresso na náš blog. Ak dodržíme dané parametre, naše espresso má extrakciu 21 – 22% (mletie cez Mahlkonig EK43).
8. Pracovné postupy a správna hygiena stroja sú dôležitejšie ako znejú. Pred každým espressom treba prepláchnuť hlavu a utrieť spršku. Taktiež portafilter, tamper aj distribútor musí byť dokonale suchý a čistý. Každodenne treba čistit espresso stroj špeciálnymi prípravkami. Nie Cif nespraví to isté.
