Questions asked the sellers of distilled alcoholic beverages included names, background, and status of respondents and physicochemical characteristics of the products. There were also laboratory production of rum spirit beverage (LBC) based on survey studies and findings from producers. The laboratory produced and market samples were analyzed for physicochemical and organoleptic attributes. The mean and standard deviation of the data obtained were presented in tables whereas the statistical differences of the obtained data were determined by ANOVA (P < 0.05) using SPSS 22. The significant means were compared using Fisher’s Least Significant Difference (LSD). The alcohol content, pH, titratable acidity, specific gravity, total solids, suspended solids and dissolved solids contents of the eleven rum spirit brands ranged from 42% to 50% and average of 47%, pH3.3- 5.1 (average pH value of 3.7), 011 to 4.5 (average value of 0.74), 0.87-0.99 and average value of 0.94, 3.03 to 32.18 (average of 8.45), 1.19 and 12.31(average of 6.08) and 1.53to 18.05 (average of 6.38) respectively.
