How Rwanda Washed Coffee Is Processed on Raised Beds

In the late 1990s, Rwandan coffee fetched just $0.33 per kilo — a price so low it kept farmers trapped in poverty despite their hard work. The problem? Unwashed beans, inconsistent processing, and middlemen taking most of the value. Yet today, Rwandan coffee is sought after for its clean, bright profile with notes of citrus and chocolate. How did this transformation happen?

Rwandan coffee’s rise began with the establishment of the Abahuzamugambi cooperative in 1999, which adopted washed processing and quality-focused methods — including sun-drying on raised beds — to produce specialty-grade beans that earn $3+ per kilo.

The Struggles Behind Rwandan Coffee Before 1999

For decades, Rwandan coffee was classified below Grade C and overlooked in global markets. Farmers lacked proper washing and processing protocols, often selling unsorted, damaged cherry. With no direct market access, profits were minimal — around $0.33/kg — barely covering survival. Most farming families lived in poverty despite their labor-intensive work.

The Birth of the Abahuzamugambi Cooperative

In 1999, 220 coffee-growing families in the former Butare Province, particularly around Maraba (Cyarumbo), formed a cooperative named Abahuzamugambi, meaning “people working together to achieve a goal.” Many members had lost family in the 1994 genocide or faced legal battles. Their mission: cut out exploitative middlemen, process coffee to higher standards, and secure better prices by dealing directly with exporters. Profits were reinvested into tools, fertilizer, and better planting stock to boost yields.

How the PearL Project Transformed Processing

In 2000, the Maraba mayor sought help from the National University of Rwanda (UNR). The following year, the USAID-backed PearL (Partnership to Enhance Agriculture in Rwanda through Linkages) project was launched, involving Michigan State University, Texas A&M, and local institutions like ISAR and KIST. By February 2001, PearL began working with Abahuzamugambi to bring Rwandan coffee up to U.S. specialty market standards.

The First Washing Station

A critical step was building a central washing station. Without immediate washing within 12 hours of harvest, sugars on the coffee bean’s pulp ferment and ruin flavor. In July 2001, with funding from UNR, OCIR-Café, ACDI/VOCA, and ISAR, the cooperative opened its first washing station near a main road in Cyarumbo. Though only 200 kg (441 lbs) of coffee was processed in the inaugural season, the results were promising.

Upgraded Infrastructure for Better Quality

In 2002, the washing station was expanded. ACPDI/VOCA funded a pipeline bringing mineral-rich water from Mount Huye, improving washing efficiency. The upgraded system allowed the co-op to process more volume while maintaining high cleanliness standards — essential for specialty-grade output.

Quality Control and Certification

With better processing came quality assurance. A new certification system was introduced in the 2002 harvest to ensure only properly sorted and processed beans reached the washing station. About half the co-op’s members achieved certification, allowing them to access discerning buyers in Europe and North America.

First Direct Export to the U.S.

Coffee experts from PearL connected the co-op with U.S.-based Community Coffee in Louisiana. In June 2002, Rwandan President Paul Kagame highlighted the program’s importance during the U.S. buyer’s visit. Impressed, Community Coffee purchased 18,000 kg (40,000 lbs) at $3/kg — well above average — marking the first direct contract between a U.S. roaster and an African co-op. The beans were roasted and sold in Louisiana as part of their premium lineup.

Fair Trade Recognition Through Comic Relief

The British charity Comic Relief also took notice. They funneled part of their 2001 Red Nose Day funds — £55 million raised in the UK and Africa — to support genocide widows via the Association des Veuves du Génocide (AVEGA). Since many Maraba farmers were AVEGA members, Comic Relief linked them with UK roaster Union Coffee Roasters (UCR). In 2002, UCR and FLO (Fairtrade Labelling Organizations) visited Maraba, granted fair trade certification, and bought all remaining unsold 2002 harvest coffee. UCR described the cup profile as “sparkling citrus with rich, sweet chocolate notes.”

The Washed Process: Step by Step

Rwandan coffee is processed using the traditional washed (wet) method, refined for high elevations and optimal cup quality:

• Harvest: Coffee cherries are handpicked during the main rainy season, typically from March to late May, mostly from smallholder farms at 1,700–2,100 meters altitude.
• Sorting: At the washing station, workers manually sort cherries, keeping only deep-red, ripe fruit. Unripe or damaged cherries are returned to farmers for local sale at a lower price.
• Depulping: Ripe cherries are immediately depulped using machines that remove the outer skin. Lighter or floating cherries are diverted for domestic sale.
• Fermentation: The beans are then fermented in water tanks for 12–18 hours at cool temperatures to break down the mucilage (sticky layer). This step is carefully monitored to avoid over-fermentation.
• Washing: After fermentation, beans are washed thoroughly to remove all remaining mucilage. Channels with flowing water help sort beans by density: higher-quality “A” grade beans sink and are separated from “B” grade.
• Grading & Soaking: A-grade and B-grade beans are channeled into separate flumes and soaked in clean water for 2 days (A) or 15–20 hours (B), allowing slight fermentation that enhances flavor complexity without defects.
• Drying on Raised Beds: Washed beans are placed on shaded, raised drying beds in thin layers. Workers constantly turn the beans and remove defective ones. Drying takes about two weeks, with protection from rain. Moisture content is reduced from ~40% to 12%.
• Hulling & Sorting: Once dried, beans are taken to a nearby technical center where machines remove the parchment layer. Final quality control includes manual sorting by skilled women. beans are bagged, labeled by grade, and stored until export.

Product Success and Global Reach

By 2006, Maraba Coffee exported 80 short tons (73,000 kg) annually, with equal shipments to the UK and U.S. The coffee became a standout single origin in several notable products:

• Maraba Bourbon: Sold in UK supermarkets like Sainsbury’s via the Union Coffee Roasters brand.
• Community Coffee Blends: Used in the “New Orleans Jazz” and hotel blends in Louisiana.
• Meantime Coffee Beer: London’s Meantime Brewery crafted a 4% ABV coffee beer (later 6%) using Maraba beans, winning a World Beer Cup gold medal in 2006 for coffee-flavored beer.
• Local Pride: Maraba Coffee became Rwanda’s most expensive retail coffee, sold at Total gas stations and InterContinental hotels.

Community Impact and Sustainability

The co-op’s success transformed the local economy. By 2003, the co-op generated $35,000 in net profit, with 70% distributed to farmers at $0.75/kg — over three times the previous average. This income covered healthcare, education, and improved living standards. The remaining 30% funded soil amendments like calcium carbonate to combat acidity and support sustainable farming. A cooperative bank and digital center were later established to offer financial services and connectivity.

Frequently Asked Questions

What is the washed coffee process used in Rwanda?

The Rwandan washed process involves handpicking ripe cherries, depulping within 12 hours, fermenting in water for 12–18 hours, washing off mucilage, soaking for 2 days (A grade) or 15–20 hours (B grade), and drying on shaded raised beds for 2 weeks until moisture reaches 12%. This method ensures clean, bright flavors and high cup quality.

Why are raised beds used for drying Rwandan coffee?

Raised beds allow for even air circulation and precise control over drying conditions. Workers can regularly turn beans and remove defective ones, ensuring uniform drying from 40% to 12% moisture. This reduces mold risk and enhances cup clarity, especially at high altitudes.

When is Rwandan coffee harvested?

Rwandan coffee is primarily harvested from March to late May, during the main rainy season. The elevation (1,700–2,100 m) and fertile volcanic soils contribute to a concentrated, high-quality cherry.

What is the altitude range for Rwandan coffee farms?

Coffee in Rwanda, especially around Maraba, is grown at 1,700 to 2,100 meters (5,577–6,889 feet) above sea level. This high elevation slows ripening, leading to denser beans with more complex acidity and sweetness.

Which international companies bought Maraba coffee early on?

Early buyers included U.S.-based Community Coffee, which purchased 18,000 kg in 2002, and UK’s Union Coffee Roasters, which bought the remaining 2002 fair trade-certified harvest. Maraba beans were also used in Meantime’s award-winning coffee beer.

How did coffee farming change life for Maraba farmers?

By 2003, farmers earned $0.75/kg — over triple previous rates — with 70% of profits paid directly. This funded healthcare, education, and farm inputs. The co-op also invested in community infrastructure like a bank and internet center.
