Wine Tasting the electronic way |
|
Science has invented an "electronic tongue" that can distinguish the taste of different grape varieties on our behalf. Although it is still in the earlier developmental stages, it is hoped by researchers that this automated device will eventually be more accurate than the human tongue when it comes to tasting wines. The electronic tongue, which is also referred to as an e-tongue, is built of a myriad of microscopic synthetic membranes mounted upon a single multi-sensor silicon chip. Distinct subtleties in the chemical composition should help each person to make distinction between different grapes and vintages due to individual sensitivity. Not only can the device tell apart wines such as Chardonnay, Malvasia and Macabeu, it can also differentiate between samples of differing vintages of the same wine. 2004 and 2005. By expanding the range of chemical components the e-tongue can recognize researchers are hoping it will be able to identify components that could change the wine quality or pinpoint wine fraud. The device can tell the difference between sweet, salty, bitter, acidic and umami tastes and functions like the human tongue. (tasty). This device was tested on nine samples of grape juice from the 2005 vintage and six samples from the 2004 vintage by the scientists. Seven months later tests were conducted again on 4 types of grapes from 2 different years, according to the Royal Society of Chemistry journal The Analyst published study. You can easily use the device as well as take it with you when you go to test wine samples on site. This device is quick, inexpensive and convenient to use. Electronic "tongues" and "noses" are being worked on by scientists to help the wine tasting industry increase their objectivity by not using "real" people. This technology is not only used in the wine industries to make more consistent descriptions of wine, but also in detecting explosives and assisting other security efforts. Since name brand wines can command big bucks on the open market, wine counterfeiting has become extremely lucrative. Fake labels are easy to make and hard to detect. The fine-wine industry is handling these counterfeit wines by using special ways including inks, bottles, holograms and bar codes to protect defrauding themselves and the customers. Australian wine company, Hardy, is using special meterial to track its bottles, and temperature-tracking tags are a new thing too. The e-tongue's ability to sift grape types by location does not guarantee its ability to hardwire the more minute details of Chateau Lafite or Mouton-Rothschild. Are you really prepared to use an expensive bottle on a robot?
