Cecilia Jiménez-Jorquera has invented an electronic wine-tasting tongue. It measures six characteristics of wine, including acidity, sugar and alcohol levels, and the variety and vintage of the grapes. Requested by "industry specialists" who need a fast way to determine the quality of wine without sending it to a lab, Jiménez-Jorquera's device works instantly, as the touch of a button.
Essentially, it's a fraud detector for use in a business where even expert humans simply aren't reliable.
