The world’s first portable device that can detect fake alcoholic drinks, was developed by the chemists from the University of Manchester. This was reported on the website phys.org.

The effect of the detector SORS is based on the principle of Raman spectroscopy when a laser beam is passed through the test substance, and then analyzed changes in the frequency of radiation caused by inelastic scattering of light in molecules. Because some of the photons interact only weakly with the atoms of the alcohol, scientists separate these particles and study their spectrum.

The developers of SORS experienced it approximately 150 known brands of Scotch whisky, rum, gin and vodka, among whom there were 40 fakes. In addition, the efficiency of the device tested on a few bottles of liquor bought in stores. First bottle was tested in a sealed form and then opened and added a little bit of methanol.

During the experiments, SORS was able to detect methanol in alcoholic beverages such as Scotch whisky, gin and vodka, which was filled in bottles made from different glass.

Previously, scientists from the Linnaeus University in Kalmar (Sweden) found that dilute whiskey with water improves its taste, as flavouring molecules of the beverage wykonawcza on its surface and better interact with the taste receptors of the tongue.

Such processes, as the researchers suggest, may occur in other alcoholic beverages with a rich aroma that improves the taste after dilution with water.
