Another tidbit from Chemical Science:

An electronic tongue that can 'taste' the grape varieties and vintages of wine has been created by Spanish scientists.

Cecilia Jiménez-Jorquera from the Barcelona Institute of Microelectronics, and colleagues, created a multisensor device and trained it to distinguish between different wines and grape juices.

When speaking with specialists of the wine industry, the need for a rapid route to obtain valuable information about product quality was noticed, explains Jiménez-Jorquera. It takes a long time to send samples to a centralised laboratory for analysis with complex equipment.

Just out of curiosity, assuming one has paid a lot of money for the wine and therefore would have drank the majority of the bottle, how easy would it be to obtain a refund based on the results of a lab test? Or even the results of a portable test? How does the consumer prove the sample came from the bottle in question, without sending the entire bottle for testing?
