Rwanda’s coffee is unusual for being almost entirely one variety: Red Bourbon, planted throughout the country at 1,500 to 2,000 metres.
The profile
Floral and citric with an orange and stone-fruit character, light to medium body, and a clean, tea-like finish. Delicate rather than powerful.
The single-variety consistency means Rwandan coffees from different hills share a recognisable family character.
The washing-station model
Rwanda rebuilt its coffee industry around centralised washing stations after 1994, taking processing away from individual smallholders and standardising it. That transformed quality within a decade and made the country a specialty origin.
Lots are traceable to a station, which is unusually good transparency.
The potato defect
Worth knowing about. A bacterial infection following antestia bug damage produces beans that smell of raw potato when ground. It affects individual beans rather than whole lots, so a single defective bean can taint a brew.
Producers and roasters sort hard for it, and it remains a known regional risk in Rwanda and Burundi.
Brewing it
Filter, light roast, a clean brewer. Delicacy is the point.
