wine bottle and glassFinely Checked Wine

DNA isn't just for fingerprinting people anymore. An Australian vintner has recently started using grape DNA in the labels of its most expensive wine. The move is a response to a rise in the number of wine swindlers switching the contents of some bottles, leaving investors duped until it comes time to uncork the wine. The technology began as a way to validate tickets for the Sydney Olympics, and might also be useful in validating a wide range of items.
