Description
Umqombothi is a traditional South African maize‑sorghum beer produced by malting, saccharification, and a two‑stage fermentation with native yeasts and lactic acid bacteria.
Technical
During saccharification at ~65 °C, amylases convert starches into glucose and maltose, which are then fermented by Saccharomyces cerevisiae to ethanol and CO₂. Concurrently, Lactobacillus spp. reduce sugars to lactic acid, imparting a mild sourness that balances the alcohol. The process relies on a delicate yeast‑LAB consortium and temperature control to prevent spoilage.
