New method of detecting fake wine

Using a laser, the fake wine detector can recognize every element: from alcohol to brand of whiskey.

With just one drop of alcohol, the laser will be able to determine immediately whether the type of 'liquid' under test is genuine or not. First, a laser beam is thinner than the hair through a transparent chip. The specimen is tiny on the chip.

Later, researchers at the University of St Andrews will conduct a light analysis of whiskey blobs.

According to the Daily Mail , fluorescence analysis of the liquid will allow accurate identification of the alcohol content in it. Typically, fake whiskey will have an alcohol content of less than 40%.

Not only that, scientists also analyzed the color and texture of the liquid, thereby recognizing the brand and age of alcohol. Even wine stored in a bucket can be read out.

The team of physicists Praveen Ashok, Kishan Dholakia and Bavisna Praveen said their research was patented technology and introduced to the market. 'The problem of counterfeit wine is a headache, the beverage industry has been constantly searching for new and cheap alcohol analysis methods. Using the power of light, we have solved this problem , "Praveen said.

Fast results promise a near future, when users can easily check whether the wine they are drinking is 'genuine' or fake.

Contrary to popular belief, whiskey is a very interesting research subject. Our method not only tracks the taste of alcohol, its reflexivity, but also the color and structure of the molecules . These are important factors in determining the age of alcohol, the process of producing alcohol and the type of alcohol you are drinking.

This research will be published in the November issue of Optics Express . It is reported that the chip used for alcohol analysis has been used by the team for biomedical research in the past. "It is great that biomedical analysis technology can be used to analyze a favorite drink of mankind ," concluded Professor Dholakia.
