Rotgutonix Digital Rotgut Detector

Finally.

Long story short: The device detects adulterated alcohol, commonly known as "rotgut."

From the website:

Rotgutonix has a built-in chemical sensor that can detect the quality of several alcoholic beverage brands. If the drink in question is rotgut, the gadget will indicate as much on its liquid crystal screen.

This is a prototype still in the marketing phase. At present, the device is set to analyze the following brands: Johnny Walker, JB, DYC, Pampero, Brugal and Havana club, although in future versions we expect that Rotgutonix will be able to analyze the chemical composition of over 20 well-known brands, mainly rum, whisky, gin, and vodka.

 

Rotgutonix was designed by Emilio Alarcón. According to the creator, "One night, I went out for a couple of drinks with some friends, I only had two drinks but the next day I had a massive hangover, I was lightheaded and nauseous. I was supposed to work that day, but I felt so horribly ill that I had to go back home. I came up with the idea for Rotgutonix while under the effects of that terrible hangover; you could say it’s an invention that was born of a hangover. Everyone knows there's a lot of rotgut being served out there. A lot of bars are getting away with poisoning us at night."
