For Rwandan coffee beans, it is better to buy raw beans or roasted beans.

Rwandans have been growing coffee since colonial times, but until 1999, its products were still classified as below Class C and in the global market.

No one cares about it. The reason for the poor quality is that farmers do not have a fixed procedure for washing coffee beans and do not process coffee fruits according to specifications in time. Buyers buy coffee beans at $0.33 per kilogram, and farmers maintain food and clothing on meagre profits earned at low prices, but they are still in a state of poverty.

In 1999, 220 coffee growers formed guilds in the Malaba area (formerly part of Butare province) to address the disease. Among the guild members, many farmers were separated from their loved ones by the 1994 mass massacre, while some husbands were jailed or were taken to the traditional Gacaca Court (gacaca) to face trial on charges of participating in the massacre. They named the guild "Abau Zam Gambi" (Abahuzamugambi), which means "people who work together to achieve their goals" in Rwandan. Farmers hope that by setting up this association, they will be able to work directly with Geely's exporters instead of peeling layers of skin through intermediary transportation companies, so as to increase profits. Farmers distribute their profits and spend them on tools, fertilizers and seeds to increase production.

In 2000, the Mayor of Malaba requested development assistance from the National University of Rwanda (UNR), which is located near the city of Butare, and the following year, the National University of Rwanda assisted in the establishment of the Joint strengthening Rwanda Agricultural Partnership (PEARL). The PEARL project is also supported by several organizations: the United States Agency for International Development (USAID), Michigan State University, Texas A & M University, and many other Rwandan organizations, including the National University of Rwanda, the National Agricultural Laboratory (ISAR) and the Gejali Institute of Technology Management (KIST). In February 2001, PEARL began working with Abauzam Gamby to improve the quality of coffee to meet the standards of the professional coffee market in the United States, and then sell the coffee to the United States.

The first problem for Malaba coffee farmers is to set up a cleaning station. The coffee fruit must be transported to the cleaning station to wash the sugar under the skin of the coffee bean within 12 hours after picking, otherwise the flavor of the coffee will be greatly damaged. In July 2001, with funding from UNR, the Ministry of Culture and Industry of Rwanda (Office des Cultures Industrielles du Rwanda,OCIR-Caf é), ACDI/VOCA and ISAR, they set up the first cleaning station near the main road in the Cyarumbo district. However, the cleaning station was not opened until the harvest time, so only 200 kilograms (441 pounds) of the harvest were washed that year. However, the result was surprisingly good. In 2002, the cleaning station was upgraded to supply more coffee processing. ACDI/VOCA is responsible for funding the construction of pipelines to bring in Mount Huye mineral water and help improve the efficiency of cleaning stations. The pipeline was opened in March 2002
