Trust in the Process: A week in Rwanda

Western Province, Rwanda.

Varietals, altitude, terroir — all these things add colour to a coffee's story but it's another crucial stage of production at origin that makes the difference: what happens during processing.

At the end of May I spent a week visiting coffee producers in Rwanda and was reminded just how vital good processing is. Everything leading up to this point plays a part, of course: plant variety, soil quality, climate, altitude, crop management - all contribute to a coffee’s potential. But it's the work carried out immediately after harvesting that determines how much of that potential reaches the cup. The processing shapes a coffee's sweetness, acidity, body and flavour.

Unlike much of Central and South America the processing here is done by the local washing station which means these hubs are weather vanes for quality; when we buy in Rwanda we are drawn to washing stations that we trust to do a good job.

As in much of East Africa, Rwandan coffee is mainly grown by smallholder farmers, many working plots of only a few hectares or less. These farmers partner with their local washing station, who will themselves partner with an exporter. We’re buying coffees from this region through the Rwanda Trading Company (RTC). Based in Kigali, where their main dry mill and quality lab is also located, RTC work with washing stations across the country.

Kigali is the capital of Rwanda, sitting pretty in the centre of the country and spreading out over rolling hills and valleys. Lots of green space; it’s a modern city that’s easy to navigate. I arrive on a Sunday morning and there’s a welcoming buzz from the proud and friendly residents - it proves to be the perfect place to acclimatise and plan the week ahead.

Over the course of the following five days I visit washing stations across Southern and Western Rwanda. Heading south west from Kigali the first station is Byimana. We arrive at the end of the day with the light fading but there are still farmers delivering their fresh pickings for processing. I'm staying in Huye Town, also known as Butare

The harvest was in full swing and the stations I visit are all busy receiving fresh deliveries of ripe cherry to wash, sort, process and dry. Drying tables are arranged on slopes to face the sun. These tables or 'raised beds' are full of cherry and parchment being checked and turned. 

As expected the majority of the coffee is washed but there were also naturals, honeys and anaerobics. In this respect the processing in Rwanda has changed a lot. In pursuit of quality the government originally specified all Rwanda's coffee had to be prepared using the washed process. Nowadays producers here are allowed to process their coffee however they like - there was great quality across the board.
