Rwandan Bourbon from Mushonyi Washed Process

When you’re searching for a bright, sweet single-origin coffee with distinct fruit and spice notes, Rwanda often comes up—but which one? With countless smallholder farms and cooperatives spread across misty highlands, finding a reliable lot with traceable processing can feel overwhelming. This article zeroes in on one standout: the washed Bourbon from Mushonyi Coffee Washing Station in Rwanda’s Rutsiro district.

At 1,827 metres above sea level, the Mushonyi Coffee Washing Station produces a washed Bourbon (BM-139) with a vibrant cup profile: red apple, cherry, cinnamon, and honey. It’s sweet, balanced, and complex—with notes of almond and chocolate in the finish.

Where Rwandan Coffee Comes From: The Rutsiro Highlands

Rwanda has rapidly earned a reputation for refined, high-quality specialty coffee. While the country is still known for its tragic history, its coffee sector has quietly transformed into one of East Africa’s most consistent sources of elegant, high-altitude lots. This particular coffee hails from the Rutsiro district in Rwanda’s Western Province—north of the better-known Nyamasheke region and also bordering Lake Kivu. The area’s fertile volcanic soils, cool temperatures, and ample rainfall (over 1,500mm annually) create near-perfect conditions for growing exceptional Arabica.

Mushonyi Coffee Washing Station: Smallholders, Big Results

The Mushonyi Coffee Washing Station is a cooperative effort. It sources ripe coffee cherries from 1,756 smallholder farmers, each cultivating around 253 coffee trees. These farmers deliver their hand-picked cherries to the station during harvest season (roughly June to September), ensuring only ripe, undamaged fruit enters the processing stream.

Once at the station, the cherries undergo rigorous selection before moving to the pulper. The mucilage is removed via a 12–18 hour washed fermentation in cool conditions, then the beans are thoroughly washed to remove any remaining fruit residue. Finally, the parchment-covered coffee is dried on raised African beds (high-altitude sun drying structures) for careful sun-drying. Workers turn the beans by hand throughout the drying period to ensure even moisture loss, stopping only once the coffee reaches a stable 14% moisture content or lower.

Bourbon Variety: Why BM-139 Matters

This lot is planted with the Bourbon variety—specifically the BM-139 cultivar. Bourbon is one of the classic, older Arabica varieties, originally from Réunion Island (formerly called Bourbon). Compared to Typica, Bourbon plants have broader leaves, grow more densely, and typically yield about 30% more fruit per plant. The beans are often rounder and produce a cup with medium acidity and pronounced sweetness. However, Bourbon is also more susceptible to disease. In Rwanda, most coffee is Bourbon-derived, including popular local variants like Red Bourbon, which is favoured for its bright acidity and fruit-forward profiles.

Cup Profile: What You Taste

This 2015 mid-season (June–September) lot delivers a clean, complex cup. Expect upfront red apple, ripe cherry, and cinnamon notes. The acidity is bright yet balanced, leading into a honey-like sweetness. On the finish, you’ll find lingering notes of cinnamon, almonds, and chocolate. It’s a classic example of Rwanda’s signature clarity and balance.
