Washington, Aug 5 : Forget wine connoisseurs, now even you can become an expert on the drink, all thanks to a group of European researchers who have devised a handheld "electronic tongue" that tells the alcoholic beverage's grape variety and vintage -just at the press of a button.
Designed for quality control in the field, the device is made up of six sensors which detect substances characteristic of a certain wine variety.
Components such as acid, sugar and alcohol can be measured by this detection, and from these parameters it can determine the age and variety of the wine.
The tongue was invented by Cecilia Jimenez-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.
Jimenez-Jorquera says "the device could be used to detect frauds committed regarding the vintage year of the wine, or the grape varieties used."
