Quality characteristics of Rwanda Coffee Bean processing; introduction to the varieties of Manor with Grinding degree

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

Most of the coffee in Rwanda is washed. The water washing method will first wash and flotation the ripe coffee fruit, then remove the exocarp, pulp and part of the pectin layer, then send the coffee into the fermentation tank, remove the remaining pectin layer and then send it to the drying ground for drying treatment, so that the water content reaches about 13%. The coffee in the picture above is dried on an African shed to avoid the smell of dirt. It is more ventilated and mildew can be avoided. During the drying process, coffee farmers will also turn the beans regularly to make the drying more evenly, and at the same time will pick out the beans of poor quality and discard them.

With the improvement and improvement of Rwandan coffee in various aspects, its quality has also made a qualitative leap. In the 2008 COE contest held by the American Fine Coffee Association SCAA, Arnomega, Rwanda, beat the Blue Mountain 1 of Jamaica and Mantenin G1 of Sumatra to defend the title. With its excellent quality, Rwandan coffee has won a place in the coffee world and won more attention.

The coffee fruit needs to be transported to the processing plant as soon as possible after picking, but due to the lack of domestic facilities, it is unable to deal with the fruit at the first time. The fruits are piled up after being picked, which will continue to develop and accelerate mildew and decay due to lack of ventilation. Rotten fruits will affect the quality of coffee and show defective flavor.

In recent years, Rwanda has made great progress in the production and processing of coffee. First of all, coffee fruits are picked manually; coffee production cooperatives are set up all over the country to provide technical guidance to coffee farmers; coffee farmers send them to coffee processing stations for cleaning and screening as soon as possible after picking, and select mature and high-quality coffee fruits for processing.
