A new electronic nose may help sniff out counterfeit whiskey... Researchers at the University of Technology Sydney in Australia developed NOS.E, a device that can detect differences among whiskies by “smelling” them.

Experienced whiskey drinkers believe they can taste and smell the difference between top-shelf spirits and cheap, imitation blends. But even the most sophisticated connoisseurs can still fall prey to fraud, which is becoming a growing problem for the whiskey industry.
Researchers at University of Technology Sydney (UTS) in Australia hope to change all that with the development of an electronic nose that can identify different whiskey styles, brands and origins by “smelling” samples. Per a paper published on April 1 in the journal IEEE Sensors, the device—called NOS.E—was able to identify differences between three blended-malt whiskies and three single-malt whiskies—made by Johnnie Walker, Ardbeg, Chivas Regal and Macallan—in less than four minutes. The prototype was 100 percent accurate on the region, 96.15 percent accurate on the brand name and 92.31 percent accurate on the style of the six whiskies it tested at the CEBIT Australia trade show in 2019.
Scientists confirmed the technology’s findings using time-of-flight mass spectrometry and two-dimensional gas chromatography, both of which are time-consuming chemical tests that must be performed in a laboratory by a trained professional. NOS.E, on the other hand, is quick and relatively inexpensive, the researchers write in the paper.
