The data for the properties of the green beer from the different cereal malts are summarized in
Table 3. The barley malt beer yielded the highest alcohol concentration (3-65 wt %) followed by
sorghum beer (3.09 wt %) and then millet beer (2.5 5 wt %) for similar falls in specific gravity. It is
possible that the low level of alcohol production from millet is due to the small size of the endosperm
available for extract production, even though equal weights of cereals were used in this
study. It is not quite clear why high colour values were obtained for millet and sorghum, but it is
possible that it is a property of millet and sorghum grains (probably due to high tannins) which are
also involved in the production of opaque beers from these cereals. Okafor and Aniche
reported that it is the technique of production that is responsible for obtaining opaque beers.
