A new invention from the Barcelona Institute of Microelectronics in Spain can make you an instant wine expert without even having to taste liquor. In the form of a handheld "electronic tongue," the device can measure various wine parameters such as sugar and alcohol content, age and variety of the wine. It's designed for quality control so there'd be no hit-or-miss tasting going on.

To be able to assess wines' quality, samples are sent to laboratories for testing. The "electronic tongue" does not only test wine quickly and on-site, it's cheap to manufacture and can be programmed to identify new varieties of wine if needed. Perfect for wine-makers, connoisseurs, and yes, even show-offs.
