Scientists Using Radioactive Signatures in Wine to Detect Vintage Fraud

20100323-bomb.jpg

From the Guardian: "Scientists have been able to pinpoint a wine's vintage to within a year by analysing the levels of radioactive carbon in the wine, a technique they say could help detect fraudulent attempts to repackage cheap plonk as a high-end tipple." Wines bottled before atomic testing began do not contain Carbon-14, whereas any bottled after do, making it (somewhat) easy to detect when someone is trying to pass off a newer wine for an old one.
