Decanter New ‘fingerprint’ method may help detect wine fraud, says study A novel technique capable of quickly pinpointing a wine's origin has great potential, scientists in Australia have said. Researchers at the University of Adelaide have found that a novel technique using ‘‘fluorescence spectroscopy’ could provide a relatively simple and rapid way to help detect wine fraud. Trials showed the method had ‘great potential’ to authenticate the geographical origin of wines, according to a study on the research published in the issue of Food Chemistryjournal dated 15 January 2021.
