Rwandan Bourbon Washed Coffee from Mushonyi Mill

If you’ve ever wondered what makes a Rwandan coffee stand out among African single origins—especially those with bright acidity and layered fruitiness—this lot from the Mushonyi Washing Station offers a clear answer. Sourced via direct trade from 1,756 smallholder farmers, it combines meticulous processing with ideal growing conditions to deliver a cup that’s both elegant and memorable.

This is a Rwanda Bourbon (BM-139) washed coffee grown at 1,827 metres above sea level, processed with 12–18 hour cool fermentation and dried on raised beds until reaching below 14% moisture. It tastes of red apple, cherry, cinnamon, and honey, with a sweet, balanced profile and notes of almond and chocolate in the finish.

Where This Coffee Comes From

The beans were grown in Rwanda’s Western Province, specifically in the Rutsiro District’s Lutero Valley—north of Nyamasheke and bordering Lake Kivu. The region features fertile volcanic soils, consistent rainfall exceeding 1,500mm annually, and elevations around 1,827m. These factors create optimal conditions for slow cherry maturation and complex cup profiles.

The coffee comes from 1,756 smallholder farmers, each cultivating roughly 253 coffee trees. They deliver ripe cherries to the Mushonyi Washing Station, which processes the lots with care and precision.

How the Coffee Is Processed

At Mushonyi, harvested cherries undergo rigorous selection by hand to remove underripe or damaged fruit. The clean cherries are then depulped and fermented in cool water for 12–18 hours. After fermentation, mucilage is thoroughly washed away in channels. The parchment is then dried on high raised beds under careful supervision, with workers regularly turning the beans to ensure even drying. Moisture levels are reduced to below 14% before storage.

This washed (wet) method highlights the intrinsic qualities of the Bourbon variety while ensuring clean, vibrant acidity and a structured sweetness.

Why This Mill Stands Out

Mushonyi Washing Station has an exceptional track record in coffee competitions. In 2010, it won the Cup of Excellence (COE) Rwanda. The following year, 2011, it secured four top placements in a single competition: 1st, 12th, 16th, and 28th. Such results reflect the mill’s consistent quality control, skilled processing, and the high potential of its farmer-supplied cherries.

This particular lot is from the 2015 harvest—a fresh arrival sourced directly from the mill—and represents the output of a well-managed, high-altitude growing community.

What This Coffee Tastes Like

On the cupping table, this Rwanda Bourbon reveals a vibrant array of flavours: red apple, cherry, and cinnamon lead the profile, supported by a natural sweetness reminiscent of honey. The acidity is bright yet refined, contributing to a balanced and elegant cup. The finish lingers with notes of almond, chocolate, and a gentle spice.

These attributes make it an excellent choice for pour-over, Aeropress, or light-roast espresso, where its clarity and complexity can shine.
