Just west of Lake Kivu, the Kanzu station rests among mineral-rich volcanic hills where smallholder farmers grow Bourbon coffee alongside bananas and beans. For this natural lot, ripe cherries are hand-sorted and dried whole on raised beds for up to 30 days, allowing sugars to concentrate slowly within the seed. The result is a fruit-forward, structured cup shaped by altitude, terroir, and careful drying, reflecting Rwanda’s continued rise as a standout origin in specialty coffee.
Located just west of Lake Kivu’s blue-green (and deadly) waters, the Kanzu station is set against verdant green hills where coffee, sugar cane, and bananas are grown. A fertile crown of land surrounds the ancient volcanoes, where decades of accumulated ash have enriched the soil with dense mineral content. Smallholder producers cultivate small parcels of Bourbon variety coffee alongside sustenance crops of bananas and beans. The Kanzu station begins collecting cherries in March, with harvest stretching through July. Thanks to thoughtful management and careful harvest planning, the station separates the crop into distinct outturns, much like in Kenya, preserving nuance and traceability within the harvest window.
For this natural lot, cherries are meticulously hand-sorted before being floated to remove lower-density fruit as an initial quality check. Rather than being pulped, the intact cherries are spread in thin layers on raised African beds to dry in the open air. Drying takes place slowly over 20–30 days, depending on weather conditions, with frequent turning to ensure even moisture reduction and to prevent over-fermentation. Careful monitoring throughout the drying phase allows the fruit sugars to concentrate gradually within the seed, contributing to structured sweetness and layered fruit character in the cup. Once optimal moisture levels are reached, the dried cherries rest in parchment before milling and preparation for export.
Wastewater from processing is treated with Effective Microorganisms (EMTechnologies™) to manage runoff and protect local waterways, safeguarding precious water resources for the surrounding community. The community around Kanzu has been the focus of sustained aid and development efforts since the mid-1990s, following the end of the genocide. Much of this progress can be traced to the work of USAID and Dr. Tim Schilling, whose efforts helped establish collection stations and cooperative structures across the region. This foundation has played a significant role in Rwanda’s emergence as a globally respected origin within specialty coffee over the past decade.
