Graham Jones at Australia's University of Adelaide thought he might exploit this variation by correlating the C14 levels in atmospheric samples from that period with the levels in vintage wines. It turns out that some vintners may be trying to pull a bit of a scam. Since, as they grow, grapes absorb a certain amount of C14 from the carbon dioxide in the atmosphere, Jones and his team discovered a way to match air levels of C14 with the wine in the bottle; a spike in C14 means your bottle is no older than a Boomer. So, if you're concerned that your Two Buck Chuck is a bit younger than advertised, just grab your trusty liquid scintillation counter, and get to tallying your decaying atoms.
