A robotic nose that can sniff out cheap whiskey that’s passed off as good stuff could revolutionize the industry.

Scientists created the sensitive, hi-tech electronic schnozz to help experts get it right every time.

When small fortunes are at stake, as rare bottles can fetch six figures at auction, NOS.E can tell the difference between expensive and ordinary spirits.

The prototype, developed by the University of Technology in Sydney, Australia, was able to identify differences between six whiskeys based on their brand names, regions and styles in tests in under four minutes.

The tests used samples from three blended malts and three single malt whiskies, including Johnnie Walker Red and Black Label, Ardberg, Chivas Regal and a 12 year old Macallan’s whiskey.

The study found that the E-Nose had 100% accuracy for region recognition, 96.15% accuracy for brand name, and 92.31% accuracy for style.

Associate Professor Steven Su, who led the research, said: “Until now, spotting the differences between whiskeys has required either a trained whiskey connoisseur, who may still be wrong.

“Or complex and time-consuming chemical analysis by scientists in a laboratory.”

The study, published in the science journal IEEE Sensors, found that the e-nose can mimic the human sense of smell by using eight sensors to detect the aroma in a flask of whiskey.

The sensors generate signals unique to the different scent molecules and send the data to a computer for analysis, where a machine is trained using “a learning algorithm” to recognize the spirit’s characteristics in a minute-long process.

Scientists say the same technology can be used to prevent the sale of counterfeit wines and perfumes and to detect illegal animal parts like black rhino horns being sold on the black market.

Prof Su said: “A rapid, real-time, user-friendly evaluation of whiskey to identify quality and detect adulteration or fraud could be very beneficial for both high-end wholesalers and buyers.”
