Whiskey is not the same whiskey. The knowledge gourmets. That's the case. So there are regionally different regulations for what conditions a brand whiskey or whiskey may be called. Now, Australian researchers have developed an electronic nose that can notify brand names, origin and style of alcoholic beverage. The verification of real whiskey varieties should help not fall into illegal reset labels.

"E-NOSE" for wholesalers and buyers

"So far, the detection of the differences between whiskeys either required a trained whiskey connoisseur, which can also make mistakes, or a complex and time-consuming chemical analysis by scientists in a laboratory," says E -Nose co-developer Steven Su from the University of Technology Sydney.

eight sensors could also recognize other odors

The e-nose has eight gas sensors. These are exposed to a touch of whiskey. This creates a signal matrix unique for the respective whiskey variety, which is evaluated by a software.
