Chemical analysis of volatile compounds from , an unrecorded alcoholic beverage from Botswana, was carried out using gas chromatography-flame ionization detection (GC-FID). Ten samples of from two different locations were analyzed. All samples had pH values in the range of 2.87-3.16. Overall the samples contained ethanol, higher alcohols and esters. Ethanol was observed to be the dominant volatile compound with concentrations ranging from 1.66-5.71 % vol. Other volatiles determined were 2-methyl-1-propanol (9.12-29.0 mg L-1) and 2/3-methyl-1-butanol (14.5-124.7 mg L-1), ethyl lactate (27.4-110.9 mg L-1) and ethyl acetate (28.3-48.5 mg L-1).
