SCIENTISTS in Spain have developed a robot sommelier with an ‘electronic tongue’ to taste different types of cava.

Rivalling the tried and tested expertise of a human sommelier, the robot replicates how humans taste using sensors that detect chemical information from the Spanish bubbly.

The device – which can even tell the difference between varieties of sparkling wine based on the amount of sugar – is the brainchild of researchers at the Universitat Autonoma de Barcelona.

It can currently identify three types of Cava – Brut, Brut Nature and Medium-Dry.

However, according to the scientists, it will soon be able to identify all types available on the market.

Scientist Manel del Valle said: “It can detect defects in the production process and may be a replacement for human testers.”
