Hwahwa – the Shona word for beer, also called doro – is Zimbabwe’s traditional opaque beer: a thick, sour, lightly fizzy brew of sorghum or finger millet malt, often with maize meal, drunk while it’s still fermenting. It’s brewed at home for family and community occasions, and its factory-made cousin is sold in cartons as commercial opaque beer. Like South Africa’s umqombothi, it’s fermented in two stages – first soured by lactic acid bacteria, then turned alcoholic by yeasts – and drunk within a day or two (Xolo et al., 2024).
Brews and Strength
A survey of traditional beers in four of Zimbabwe’s provinces found that the commonest were a seven-day beer called doro rematanda, a by-product of it called muchaiwa, and a one-day brew called chikokiyana, made in similar ways across the provinces. The seven-day beer averaged about 4.1 g of alcohol per 100 ml, muchaiwa 2.8 g and chikokiyana 3.6 g – in the same range as commercial opaque beer (about 3.5 g per 100 ml) and close to lager (Saungweme et al., 1999).
The Iron Question
The same survey found very high iron in traditional beer: a median of 52 mg of ionic iron per litre in the seven-day beer, against 0.1 mg/L in clear commercial lagers and 3.6 mg/L in commercial opaque beer (Saungweme et al., 1999). That matters because traditional home-brewed beer is the dietary source of iron behind African iron overload, a condition in which iron builds up in the liver. A study of 36 African families found that it depends on both the beer and an inherited iron-loading gene: in people carrying one copy of the gene, drinking iron-rich traditional beer raised average transferrin saturation from 30% to 81% (Gordeuk et al., 1992). The authors of the Zimbabwe survey call for iron-overload prevention to cover all these beers. If you brew at home, use a food-grade plastic, glass or stainless-steel vessel rather than an iron pot or drum.
Grain Quality
Opaque beers are made from maize and sorghum that can carry moulds and mycotoxins: a study of South African maize-based opaque beer found several mycotoxins occurring together (Adekoya et al., 2018). Use clean, fresh, mould-free grain and malt, and discard any batch that smells rotten or grows coloured mould.
Relatives
Hwahwa sits in a family of African grain beers: West Africa’s pito, Kenya’s busaa and Ethiopia’s tella. For a non-alcoholic soured maize drink from the same region, see maheu.
