Testing Of Wine Electronically

"Electronic tongues" have been made for those people who have trouble telling the difference between tastes in wine.

While such devices are still in their formative stages, researchers believe they will invent wine-tasting machines more objective than human wine tasters. The e-tongue is built from a single chip multi-sensor comprised of mini -synthetic membranes. 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 . It is the hope of researchers that by allowing the electronic tongue to recognize a wider range of chemical components it will be able to distinguish altered quality of wine or instances of fraud.

The device was created using the human tongue as a guide and has sensitivities to five different taste sensations: bitter, sweet, salty, umami and acidic. (small dish). Nine samples from 2005 vintage and six samples from 2004 were used by scientists to test the device. 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.

Scientists are inventing new methods, such as mechanical "tongues" and "noses", to effectively differentiate between molecules as a way to make the win tasting industry more objective. 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. Creating a fake label is easy but it is difficult to detect. The wine industry is tackling this problem by using special inks, bottles, holograms and bar codes which can protect them and the potential customers from frauds.

The Australian wine company, hardy, uses genetic vine material in neck seals to keep track of its more precious bottlings while the temperature-tracking tags are a recent innovation. The electronic wine taster can be useful for discerning different grape varieties, but whether it can detect the subtle differences between wines, the way a human can, is another matter. Other than that , you are ready to spend lavishly an expensive bottle on a robot?
