2.1. Preparation of opaque beer
Opaque beer was prepared by simulating the traditional method as practised in the rural households of Zimbabwe, with the help of an experienced old lady, K.Masanga, from Mberengwa. Three types of beers were prepared by varying the ratios and types of raw materials used in the initial making of a porridge as
follows:
Beer 1, sorghum meal and sorghum malt in the ratio
2:1.
Beer 2, sorghum meal and finger millet malt in the
ratio 2:1.
Beer 3, sorghum meal, maize meal and millet malt in
the ratio 1:2:2.
The three types of beers were prepared under normal and HG fermentation conditions.
