Electronic Toungue Samples Wine
Rapid, portable detection of wine composition could preserve quality and stop fraud
You don't need a wine expert to identify a '74 Pinot Noir from Burgundy "“ a handheld "electronic tongue" devised by European scientists will tell you the grape variety and vintage at the press of a button.
The tongue was invented by Cecilia Jim©nez-Jorquera and colleagues from the Barcelona Institute of Microelectronics, Spain, and is reported in the Royal Society of Chemistry journal The Analyst.
Wine industry specialists told the researchers they lacked a fast way to assess quality of wines "“ it takes a long time to send samples to a central laboratory for processing.
This new tongue is not only swift, but also portable, cheap to manufacture, and can be trained to "taste" new varieties as required.
Jim©nez-Jorquera says "the device could be used to detect frauds committed regarding the vintage year of the wine, or the grape varieties used."
