Robot Tongue Identifies The Correct Beer Every Time

On top of being cold blooded killers, hell bent on destroying the human race, our new robotic overlords will also be beer connoisseurs.

However it looks, Méndez and colleagues developed an electronic tongue that accurately distinguished between four styles of lager beer 100 percent of the time. A variety of screen-printed sensors "taste" electrochemical compounds in the beer to predict the brews' color index and alcoholic strength 76 percent and 86 percent of the time.

So... its some sort of Mass-Spec or chromatography for beer. Really not exciting new tech

Is that you Bender?

The beer styles they chose (alcohol-free, pils, doppelbock, and Euro strong - all lagers) are all quite different from one another in terms of color, sugars, ABV, etc.
I'm not saying it isn't impressive, but a bigger feat would be to pick between different beers of the same style. Some of those are the beer equivalent of comparing McDonalds burgers to Shake Shack. Not even quality-wise, just sheer differences.

Yeah, my beer tongue is far more sensitive and specific, well at least for the first four or five.
