A reliable method for the characterisation of vodkas has been developed by application of solid‐phase microextraction (SPME) and gas chromatography/mass spectrometry (GCMS). Sixty‐four samples of commercial Canadian and American vodkas, and one sample each of Japanese and German vodkas, were investigated in this study. The procedure yielded reproducible chromatographic profiles. The detected components were ethyl esters of C 8 to C 18 fatty acids at μg litre −1 levels, various additives and contaminants. Distinctive profiles were observed for various brands. Markers for differentiating between Canadian and American vodkas were identified. The results of this study indicate that vodkas are differentiated by the combined effects of the original raw materials, any added substances, and differences in processing.
