Traditional African beers: sorghum, millet and banana
Long before industrial lager, communities across Africa brewed beer from sorghum, millet, maize and banana. These beers are still made today. They are well worth understanding.
A different kind of beer
Traditional African beers are usually opaque, low in carbonation and lightly sour. They are made from locally grown grain or fruit, fermented by a mix of yeasts and lactic acid bacteria and meant to be drunk fresh. Many are sold or shared within days of brewing.
Names and recipes vary between communities and households, so any short overview simplifies. What follows describes widely documented patterns rather than a single standard.
It helps to think of these as living foods, closer to fermented drinks like kefir or sourdough than to a lager. They are cooked, soaked and left to ferment, then served close to the vessel they were made in.
Sorghum and millet beers
Sorghum and millet are hardy cereals that grow well in hot, dry regions. Examples include dolo in parts of West Africa and pito in Ghana and Nigeria. Umqombothi in South Africa is brewed from maize and sorghum malt. Ethiopian tella is a home-brewed grain beer, often flavoured with a native shrub called gesho.
These beers share a method. Grain is malted by soaking and sprouting, then dried. Malt provides enzymes that turn starch into fermentable sugar. Part of the grain is cooked, then mixed with malt and water and left to ferment.
Why sorghum needs a cereal cook
Starch has to gelatinise before enzymes can break it down. Barley starch gelatinises at a lower temperature than sorghum starch, so a barley mash can be done in one vessel at around 65 °C (149 °F). Sorghum starch needs more heat, so brewers cook part of the grain separately at or near boiling, then add it to the malted portion.
This is also why sorghum beer is rarely clear. Sorghum proteins and starch particles stay in suspension, so the beer is cloudy and thick. Many people drink it with the sediment stirred in, as part of its character.
Banana and fruit beers
In East Africa, banana beer is made across the Great Lakes region. Rwandan urwagwa and Tanzanian mbege are examples, though recipes differ. Ripe bananas are pressed for juice, often combined with a grain such as sorghum or finger millet, then fermented. The result is sweet-tart, lightly fizzy and fruity.
Banana beer is a reminder that beer does not have to start with barley. Any sugar source that yeast can ferment qualifies, though how a country classifies the drink for tax or labelling differs.
Sweetness varies with how long fermentation has run. Young banana beer is sweeter and less alcoholic, while older batches are drier and stronger. Fruit juice contains its own sugars, so the grain portion mainly adds flavour and body.
Why they are sour and short-lived
Traditional fermentations are not sterile. Lactic acid bacteria grow alongside yeast and produce lactic acid, which gives the sour taste and also protects against some spoilage organisms. Fermentation continues in the container, so the beer changes by the day. It may taste mild on day one and sharp by day four.
Commercial opaque beers in southern Africa keep this sour, cloudy style in cartons that are shaken before drinking and have a short shelf life. Without pasteurisation, they must be kept cool and consumed quickly.
How they compare with modern lager
A modern lager is clear, filtered, carbonated and shelf-stable. A traditional African beer is cloudy, lightly carbonated, sour and perishable. Neither is better. They answer different needs: one travels well and is consistent, the other is local, fresh and communal.
Brewers working with sorghum today also make gluten-reduced and gluten-free beers by using sorghum in place of barley. Rules for calling a beer gluten free differ by country, so check the local standard. For more on how styles fit together, see our beginner's map of world beer styles.
Another difference is where flavour comes from. Lager flavour comes mostly from malt, hops and clean yeast. Traditional beers get theirs from grain, fermentation organisms and sometimes added plants such as gesho. A cold, clear lager sits at the other end of the spectrum.
Law, safety and respect
Home and village brewing sits under different rules in different places. In some countries alcohol is restricted or banned. Local law comes first. If you are interested in making these beers, learn from people who brew them and remember that hygiene matters: a poorly managed fermentation can spoil. Where alcohol is restricted, read non-alcoholic beer styles explained.
Common questions
What is sorghum beer?
Beer made from sorghum grain, usually malted and partly cooked, then fermented by yeast and lactic acid bacteria. It is typically cloudy, sour and lightly carbonated.
Why is traditional African beer cloudy?
Sorghum and millet leave proteins and starch particles in suspension. The beer is rarely filtered. The cloudiness is normal.
Is traditional African beer gluten free?
Sorghum does not contain the gluten proteins of barley, but a traditional beer may be made with mixed grains. Check ingredients and check your local rules on gluten-free claims.
How long does it keep?
Not long. Without pasteurisation or filtration it keeps changing. Many are best within a few days.
