Rwanda's Bourbon arabica grows between 1,400 and 2,000 metres, where cool nights slow cherry maturation and concentrate sugars. Most production comes from smallholders with a few hundred trees each.
Good practice starts with healthy seedlings, mulching against erosion, shade trees, and annual pruning to keep three to four productive stems. Selective handpicking of only red-ripe cherries is the single biggest quality lever.
Cherries must reach a washing station within hours of picking. Fully washed processing — pulping, fermentation, washing channels, and raised drying beds — is what earns specialty premiums, often through a cooperative that handles export contracts.
