Components
Sorghum (often partly malted)essentialThe fermentable grain that defines the brew
Millet (sometimes added)optional
Wateressential
Wild yeasts and lactic bacteria (starter/back-slop)essentialDrives the souring fermentation
Technique
- Malting the sorghum
- Sprouting develops enzymes that convert starch to fermentable sugars
- Wild/spontaneous fermentation
- Yeasts and lactic bacteria produce both alcohol and the signature sourness
- Back-slopping (using prior brew as starter)
- Carries over an active microbial culture for a reliable, fast ferment

Sorghum → Barley/wheatinadmissible
Produces a different beer entirely, not Sudanese marisa
Live fermentation → Adding commercial alcohol to grain waterinadmissible
Removes the sour fermented character central to marisa
Common mistakes
- Confusing it with clear, filtered Western-style beer
- Over-fermenting until harshly sour or vinegary
- Assuming it is shelf-stable — it is a living, perishable brew
Provenance
