Kayumbu Station was built by the Rwandan army. Army-built stations are constructed to receive huge volumes of cherry each season. Rwacof purchased the station in 2013 and has been working with the 1,055+ farmers delivering cherry to the station ever since.After purchasing cherry from producers, Kayumbu sends the cherry through a strict sorting process. First, washing station staff remove any lower quality cherry through flotation. Then, a specially trained staff visually inspects the remaining cherry for any visual defects. Following sorting, cherry is spread in a thin layer on raised beds where it is turned regularly to ensure even drying. It takes approximately 3 weeks for cherry to sundry.

In order to devote their attention to producing the highest quality Naturals possible, Kayumbu only produces Naturals at the beginning and end of the harvest season, when production at Kayumbu is the lightest.
