This study was aimed at evaluating the level of bacterial contamination in some fruit wine produced in Nigeria and to determine the antibiotic susceptibility and physiological profile of the bacterial contaminants. Thirteen bacteria isolates were recovered from the different local fruit wine. The total bacteria colony count of the samples ranged from 12 x 107 to 90 x 107 . The antibiotic susceptibility profile of the isolates was determined and 97% sensitivity to the clinically relevant antibiotics was noted while 3% resistance was found. Physiological parameters including temperature, pH, benzoic acid and sodium chloride were found to have profound effect on the growth rate of isolates. The results of this study showed that most of the fruit wine samples examined did not meet bacteriological quality standards. Hence, it is recommended that regular monitoring of fruit wine production quality should be carried out by putting in place appropriate agency.
