Starting a microbrewery in Africa: grain, water and power

Africa is many markets

Climate, law, currency, infrastructure and drinking habits differ widely between and within countries. Treat any general advice as a starting list of questions. A coastal city with a port has different costs from an inland town at altitude. Some places restrict alcohol altogether. Where that applies, local law comes first and a non-alcoholic product may be the only option.

Grain: barley, sorghum, maize and cassava

Barley malt is mostly imported, which adds freight, duty and currency risk. Many brewers use local grains instead. Sorghum, maize and cassava can all be brewed. Sorghum needs a cereal cook because its starch gelatinises at a higher temperature than barley's. Raw grain brings few enzymes of its own, so you must add enzymes or malted barley to convert the starch.

Our guide on starting a brewpub in Southeast Asia covers a similar rice-and-malt balance. Contract brewing can test a recipe before you buy a plant.

Local grains change the beer. Sorghum gives a dry, slightly tangy character. A gluten-free version needs enzymes rather than barley malt. Maize lightens body and flavour. Cassava is mostly starch and needs a cook. Run small test brews first. Check yield, because a grain with less extract costs more per litre of beer.

Beers brewed from sorghum or maize have a long tradition in many places. Learn from the brewers who make them. Talk to your customers about what they like.

Water: borehole, mains and treatment

Borehole water can be clean and mineral-rich or very hard, salty or contaminated. Mains water may be chlorinated and may be unreliable. Test the water for hardness, alkalinity, chloride and microbiology before you buy equipment. Plan for filtration, carbon treatment and, where needed, disinfection.

Water is also food safety. A brewery that rinses with untreated water risks infection in the beer and illness in the drinker.

Storage tanks for water need cleaning and a cover. A tank on a roof in direct sun warms the water, which then needs cooling before it reaches the mash or the heat exchanger. Keep a spare filter cartridge and a basic test kit on site. Measure chlorine, pH and hardness every week.

Power and cooling

Grid power may fail for hours. A brewery without backup power can lose a brew mid-boil or a tank to rising fermentation temperature. Plan a generator or battery for the chiller, the controls and the pumps, or choose equipment that can sit through a short cut. Fuel and maintenance are running costs.

Fermentation in a warm room needs chilling. Ale yeast can be fine in the low 20s °C, but lagers need 8 to 13 °C. Insulate tanks and the cold room well, because cooling is where power cuts hurt most.

Solar panels can offset some daytime use, but a brewery's load at night for chilling is hard to cover without batteries. Ask an electrician for a load calculation before you buy a generator. Place it where fumes and noise will not disturb neighbours.

Equipment and spares

Imported kit arrives with long lead times and customs steps. Choose simple, robust designs with parts you can source locally, such as standard pumps, valves and fittings. Keep a spare for every part that can stop the brewery. See importing brewing equipment for the freight and installation side.

Ask your supplier for a clear list of wear parts. Stock them. Standard fittings that a local workshop can weld, repair or replace keep the brewery running when imported parts are stuck at a port.

Licences, price and customers

Licensing follows the usual chain: company, premises, production and sales licences, duty registration, labels. Rules differ by country and change, so check with the national regulator or a licensing adviser. See brewery licensing: the steps most countries share.

Price against what customers already pay. In many places a mass-market lager sets the reference. A craft beer must justify a premium with freshness, flavour or story. Build costing from real volumes. Test it with a full start-up cost sheet.

Cold chain beyond the brewery matters too. Beer sold in a hot market and kept in the sun loses freshness quickly. Draught in a bar with working cooling is usually safer than bottles on a warm shop shelf.

Common questions

Can I brew with sorghum instead of barley?

Yes, many brewers do. Sorghum needs a cereal cook and added enzymes or malted barley to convert its starch. The beer tastes different from a barley beer.

Do I need a generator?

Where the grid is unreliable, usually yes. Size it to run the chiller, the pumps and the controls. A power cut during fermentation or conditioning can spoil beer.

Is borehole water safe to brew with?

Only after testing. Borehole water can be hard, salty or contaminated. Test it, treat it and re-test regularly.
