article imageElectric Tongue Tastes wine

By Bob Ewing     Aug 4, 2008 in Lifestyle
You do not know one wine from another, no problem an electric tongue has been invented that can tell you what you need to know.
So you are no wine expert, no matter, a handheld "electronic tongue" devised by European scientists will tell you the grape variety and vintage at the press of a button.
The device was designed for quality control in the field and is made up of six sensors which detect substances characteristic of a certain wine variety. The device can measure components such as acid, sugar and alcohol and from these parameters it can determine the age and variety of the wine.
Cecilia Jiménez-Jorquera and colleagues from the Barcelona Institute of Microelectronics, Spain, invented the device and 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 swift portable, cheap to manufacture, and can be trained to "taste" new varieties as required.
Jiménez-Jorquera says "the device could be used to detect frauds committed regarding the vintage year of the wine, or the grape varieties used."
