Abstract
Suitability of two blends of Utazi (Gongronema latifolium). Bitter leaf (Vernonia amygdalina) and Bitter cola (Garcinia kola) in ratios 1:6:2.3 (THS 1) and 0:1:2 (THS 2) as replacements for commercial hops in sorghum lager brewing was investigated. Proportions of vegetables in both blends were obtained through linear programming. Both blends were analysed for fat. tannin. essential oil, total resin and alpha acid contents and then tested on pilot scale brewing trials alongside commercial hops that served as control. Beer samples produced were analysed for their chemical composition, colour, clarity, head foam (formation and retention), bitterness and flavour. The blends of vegetables tested had similar chemical composition and organoleptic properties as those of commercial hops and offer replacement potentials for the latter in sorghum-based lager beer brewing. However, the use of the vegetable blends will require an efficient filtration system for production of beer of acceptable clarity.
