Fancy a pint? The robotic tongue so sensitive it can taste different beers - and make human tasters redundant

The robotic tongue so sensitive it can distinguish between different beers - and tell if you've been served a bad beer System uses 21 sensors to analyse different liquids Researchers trained it to trained it to distinguish between Schwarzbier, lager, double malt, Pilsen, Alsatian and low-alcohol Can also check the beer has the correct alcohol level Researchers have created the ultimate beer taster - a robot tongue so sensitive it can distinguish between different varieties and even check alcohol content. 'The concept of the electronic tongue consists in using a generic array of sensors, in other words with generic response to the various chemical compounds involved, which generate a varied spectrum of information with advanced tools for processing, pattern recognition and even artificial neural networks,' said Manel del Valle, the main author of the study. The electronic beer tester: Spanish researchers have managed to distinguish between different varieties of beer using an electronic tongue. 'Using more powerful tools – supervised learning – and linear discriminant analysis did enable us to distinguish between the main categories of beer we studied: Schwarzbier, lager, double malt, Pilsen, Alsatian and low-alcohol,' Del Valle said.
