[Telegraph via Slashdot] "Industry experts claim the market for vintage whiskey has been flooded with fakes that purport to be several hundred years old but instead contain worthless spirit made just a few years ago. Now researchers at the Oxford Radiocarbon Accelerator Unit have developed a method that can pinpoint the date a whiskey was made by detecting traces of radioactive particles created by nuclear bomb tests in the 1950s. 'Gives a whole new meaning to the idea of the whiskey "bloom", doesn't it?
"It is easy to tell if whiskey is fake as if it has been produced since the middle of the twentieth century, it has a very distinctive signature," says Dr. Tom Higham, deputy director of the facility. Nuclear bomb testing in the 1950s saw levels of carbon-14 in the atmosphere rise around the world so the amount of isotope absorbed by living organisms since this time has been artificially elevated.
