Aged Scotch whisky can cost a fortune. For example, a bottle of Macallan Fine and Rare 60-Year-Old 1926 was auctioned off for $1.9 million. What a perfect target for counterfeiters! Nuclear science to the rescue: Scientists at the Scottish Universities Environmental Research Center have developed a method to determine a whisky’s age. The radioactive fallout from the detonation of atomic bombs in the 1950s and 1960s has enabled scientists to create a Carbon-14 calibration curve based on whiskies with known age.
