Differentiation of bourbon whiskies using gas chromatography and cluster analysis


, : Differentiation of bourbon whiskies using gas chromatography and cluster analysis. Texas Journal of Science 52(4): 345-352, November

The practice of counterfeiting liquors in drinking establishments is common today. In order for a forensic scientist to help prevent this from occurring, a database of chromatographs must be compiled of all the spirits available. In this study, five brands of bourbon were analyzed and cluster analysis was applied to the gas chromatographic data. The cluster analysis showed the least expensive brand and the most expensive brand to have the greatest differences, but the three other brands formed one large third group. These groupings showed that one can distinguish one brand of bourbon from another. This study should prove useful to consumers and distillers to help in the detection of counterfeit liquors.
