E-Nose Sniffs Out the Good Whiskey


The Nos.e analyzed and identified different whiskey samples at CEBIT 2019.

The results of the research showed that Nos.e was on par with a gas chromatography device in identifying whiskey brands.

New research describes an electronic nose (e-nose) that can analyze whiskies and identify a whiskey’s brand with over 95% accuracy after a single whiff.

Researchers at Australia's University of Technology Sydney based NOS.E on an e-nose originally developed to detect illegal animal parts sold on the black market.

NOS.E has a vial to insert the whiskey sample, and a gas sensor chamber to contain the whiskey's scent; the chamber reads the various odors and transmits the data to a computer, then key scent features are extracted and analyzed by machine learning algorithms to identify brand, region, and style of whiskey.

The researchers compared NOS.E's analysis of a half-dozen whiskies to that of a state-of-the-art gas chromatography device, and found both methods yielded similar accuracy.
