Is nothing sacred? Some fiends apparently fake Scotch brands. Fortunately, researchers at the University of Strathclyde in Scotland have devised some new methods involving optic fibers for distinguishing between authentic and counterfeit Scotch whisky brands. As R&D Magazine reports:
The researchers analysed 17 samples of blended whisky, looking at the concentration of ethanol in the samples without diluting them and the residue of dried whisky. They did so with mid-infrared spectrometry, used with immersion probes that incorporate novel optical fibres developed by Scottish based company Fibre Photonics Ltd who co-sponsored the research. The procedures developed can provide prompt, accurate analysis without the complexity and cost of some other systems.
The levels of ethanol and colourant led them to identify correctly the eight authentic and nine counterfeit samples.
What's next? Fake truffles?
