Tasting notes
From Redemption Roasters
"Anoxic natural process from Izuba Community Washing Station in Kayanza Province. Expect notes of cola, cranberry, and lime — intense fruit-forward character with a clean, structured finish typical of high-altitude Burundian Red Bourbon. The water pillow anoxic process creates a controlled oxygen-free environment during fermentation, amplifying the fruit complexity without risking over-fermentation."
Cuppd note
The anoxic water pillow process — sometimes called "underwater natural" — submerges the whole cherry in sealed tanks filled with water and CO2, displacing all oxygen. The result is a fermentation environment that's more controlled than a standard anaerobic tank and more extreme than a standard natural drying bed. Kayanza Province in northwestern Burundi is one of the better-defined specialty growing zones in the country.
Redemption are also the only roaster in this database publishing green price per kg on their product pages. That information exists at the FOB stage for most specialty lots — few roasters share it openly. It signals that the relationship with Izuba is direct and the pricing is defensible.
Redemption Roasters was founded to train and employ people with experience of the criminal justice system. Direct trade, strong on experimental processing, and one of the most transparent roasters in London on supply chain pricing.
Flavour fingerprint
Who it\'s for
Built for: The Process Nerd
Anoxic water pillow is a precise and distinctive process — not widely used, well-documented, and clearly readable in the cup. Cola and lime are not accidental descriptors; they're the specific outputs of this fermentation method on Red Bourbon.
Also suits: The Bright Drinker
The cranberry and lime acidity are high and clean. If you like washed East African coffees but want to understand what process adds, this is a good bridge lot.
