Is that vintage a fake? Now you can find out.

 

    It that bottle of Bordeaux your friend is trying to sell you really from a fine vintage like 2000?  Or is it a relabeled fake, actually from the mediocre 1991 vintage?

    Now you can find out. Scientists have come up with a way to detect wine vintages. It's based on carbon dating -- similar to the way they estimate the age of prehistoric fossils.

    Basically -- and this is the eww! factor -- they measure how much radioactivity there was in the grapes left over from the atomic bomb testing of the 1940s. I'm not sure I'm glad to know that.
