This mildly sweet, lightly fizzy beverage has been brewed in Rwandan homes for centuries from overripe bananas. The natural fruit sugars ferment into a gentle, refreshing drink enjoyed at celebrations and gatherings. Traditionally served in shared calabash bowls, it is best sipped fresh while still lightly effervescent.

Ingredients
For the Banana Mash
- 8 very ripe bananas (skin mostly black)
- 4 cups filtered water, room temperature
- 1/4 cup sorghum flour
- 1/4 cup granulated sugar
For Fermentation and Bottling
- 1/2 teaspoon active dry yeast
- 1 cup additional filtered water
- 1 tablespoon honey (optional, for bottle conditioning)
- Pinch of ground cinnamon (optional)
Directions
- Peel the bananas and place them in a large clean bowl, then mash thoroughly with a wooden spoon or potato masher until smooth with no large lumps remaining.
- Stir in the sorghum flour and sugar, mixing until evenly combined, then add 4 cups of filtered water and whisk until the mixture is uniform.
- Pour the mash into a large glass or food-grade plastic fermentation vessel, cover loosely with a clean cloth, and let it rest at room temperature for 24 hours to begin wild fermentation.
- After 24 hours, sprinkle the active dry yeast over the surface and stir gently to incorporate, then cover the vessel with an airlock or a loose cloth secured with a rubber band.
- Allow the mixture to ferment at room temperature (68-75°F) for 48 to 72 hours, stirring once daily; the beer is ready when it is lightly fizzy, slightly tangy, and smells fruity with a mild alcoholic aroma.
- Strain the fermented beer through a fine mesh strainer lined with cheesecloth into a clean bowl, pressing gently on the solids to extract all liquid without forcing pulp through.
- If you want extra fizz, stir in the optional honey and a pinch of cinnamon, then bottle the beer in clean swing-top or thick plastic bottles, leaving 1 inch of headspace at the top.
- Seal the bottles and let them condition at room temperature for 12 to 24 hours for natural carbonation, then transfer to the refrigerator to slow further fermentation.
- Chill thoroughly for at least 4 hours before serving, and pour gently into cups or small calabash bowls to preserve the light effervescence.
Cook’s Notes
- Use the ripest bananas you can find; black-spotted or fully blackened skins produce the sweetest, most flavorful beer with stronger natural fermentation.
- Sanitize all equipment with boiling water before use to prevent off-flavors and spoilage from wild bacteria or mold.
- For a stronger or weaker drink, adjust fermentation time: shorter (24 to 48 hours) yields a sweeter beer, while longer (3 to 5 days) produces a drier, more alcoholic version.
- Traditional Urwagwa is often brewed with just bananas and sorghum without added yeast, relying on wild fermentation from the fruit skins; rinse bananas lightly but do not scrub if you want this authentic flavor.
- Open bottles slowly over a sink as natural carbonation can cause them to fizz over, especially after warm conditioning.
