The world of fine spirits is one of subtleties, and Uwe Bunz, a researcher from Heidelberg University in Germany, has developed a system for solving one of the problems that comes with that high brow industry. Using what New Scientist terms a "synthetic tongue," Uwe Bunz is able to detect whether a sample of whisky actually matches with what it's labelled as.

Fraud is rife in the fine whisky market, simply due to the fact that it is exceedingly difficult to definitively tell the difference between batches. Even experienced tasters might have trouble telling the difference between a blend and a single malt, and so Bunz system helps to give buyers added confidence before they purchase. The tongue effectively tastes a sample of whisky, and then it uses a dying agent to color that sample. If colors differ, it means the whisky doesn't match the original sample and is thus a fraud.
