If this sugar is not removed within 12 hours of picking, it may ferment, and the flavour of the coffee is then impaired. They built the first station in July 2001 in the Cyarumbo sector, close to the main road, with funding from UNR, the Office des Cultures Industrielles du Rwanda (OCIR-Café), ACDI/VOCA, and the Institut des Sciences Agronomiques du Rwanda (ISAR).
However, the results were reasonably good, and the station was upgraded to allow more coffee to be processed in 2002. To bring mineral water from Mount Huye to the upgraded station, ACDI/VOCA helped fund a pipeline, which opened in March 2002.
