Doro is the traditional opaque beer of Zimbabwe, brewed at home from millet or sorghum malt over about a week. A malt porridge is cooked and left to sour for two days, boiled down, fed with more malt, and then mixed with fresh porridge and water to start the alcoholic fermentation. It is drunk while still fermenting, at about 4 % alcohol.

Recipe
Amounts from a sourceOne household brew of sorghum malt, as described by Benhura et al. (1989) and summarised by Lyumugabe et al. (2012). A survey of Zimbabwean households found that most beers are made mainly from bulrush millet and finger millet malts, with sorghum malt and sprouted maize used only occasionally.
spontaneous; no starter is added. Misihairabgwi et al. say the yeasts and bacteria are believed to come from the malt and from fermentation pots passed on from earlier brews.

Doro is the traditional opaque beer of Zimbabwe, brewed at home from millet or sorghum malt over about a week. A malt porridge is cooked and left to sour for two days, boiled down, fed with more malt, and then mixed with fresh porridge and water to start the alcoholic fermentation. It is drunk while still fermenting, at about 4 % alcohol. Made in 9 steps over 8.2 days – 9.3 days. The longest step, germinate in a sack, takes 2–3 days (Lyumugabe F 2012). Saccharomyces cerevisiae, the main yeast in 13 household beers does most of the fermenting.
Doro is made in two separate sour stages. A cooked malt porridge (masvusvu) sours for two days into mhanga, which is boiled down by a quarter before more malt is added. Only on the sixth day is fresh porridge mixed in to start the alcoholic fermentation, so the whole brew takes about a week, much longer than dolo or ikigage, which are ready in 12 to 24 hours. Most household doro is made from millet malt.
In 1911 Rhodesia passed the Kaffir Beer Ordinance, which gave town councils a monopoly on making and selling African beer in their areas. Salisbury's council began brewing its own beer in 1936. Until 1961 the colonial authorities allowed no private firm to make opaque beer, and in that year Heinrich's Chibuku Breweries was given permission to operate. By the late 1960s the traditional seven-day home brew was disappearing from the shebeens of Salisbury, as commercial opaque beer in cartons took its place (Chimhete 2023).
