Uruwaga is a traditional Rwandan fermented banana beer made by boiling, mashing ripe plantains, inoculating with a mixed culture of Saccharomyces cerevisiae and lactic acid bacteria, and fermenting at ambient temperatures for 48–72 hours.
Origin: Rwandan people (Traditional) — Rwanda
See full technique reference →During fermentation, starches are hydrolyzed to sugars that yeast converts to ethanol and CO₂, while lactic acid bacteria produce lactic acid, lowering the pH. The combined action of yeast and bacteria creates a mildly alcoholic beverage with a characteristic sourness and banana aroma. The process also generates volatile esters that contribute to the drink’s flavor profile.
Primary Reaction
Starch → glucose → ethanol + CO₂ + lactic acid
