Artificial intelligence receptor chips are placed on a small plate, and the principle of their operation is similar to a human language device.

Scientists used two different types of metals, located on gold and aluminum fields in a staggered manner. When the plate is immersed in the whiskey, the plasmon resonance of the metals changes. Then the light absorption of the receptors is measured, which differs in the samples.

Artificial intelligence determines the type of drink, as well as the type of barrel in which it was made and the shelf life. The 12-, 15-, and 18-year-old whiskey from Glenfiddich, Laphroaig, and Aldi Glen Marnoch were used to test the device. The invention should help to look for counterfeits to protect the rights and health of buyers.
