Tech Tuesday … “The Electronic Tongue” ~ August 2, 2011

Tech Tuesday . . . where wine & tech meet

Electronic tongue created to be wine connoisseur

You may pride yourself on an ability to determine Lambrini from Moët, but an electronic “tongue” has been devised to taste the difference between different types of cava (sparkling wine) on your behalf.

Researchers from the Group of Sensors and Biosensors at the Universtat Autonoma de Barcelona have employed a combination of chemical measurement hardware and software algorithms to recreate the human taste system in a man-made device.

Specifically, the system identifies the differences between the wines by analysing their sugar content, as the amount of sugar added to the wine during fermentation stages determines what type of cava is produced.
