    Abstract

    Neat Scottish whiskies and the local source water used for and during whisky production have been analysed for their H-2 and O-18 isotopic composition by High Temperature Conversion-Isotope Ratio Mass Spectrometry (TC/EA-IRMS). With coefficients of determination R-2 for delta H-2 and delta O-18 of 0.71 and 0.88, respectively, measured delta H-2 and delta O-18 values for water used in the production of Scottish whisky were found to be well correlated with the delta H-2 and delta O-18 values observed for the corresponding whiskies. By plotting bulk H-2 against bulk O-18 isotope abundance data of authentic whisky and counterfeit whisky samples it was possible to discriminate between samples of authentic whisky and samples of counterfeit whisky.
