A new study : Scientists use carbon-dating to check wine vintages
Due to the widespreaded „vintage fraud”, a team of researchers in Australia have came up with a test that uses radioactive carbon isotopes left in the atmosphere by atomic bomb tests last century and a method used to date prehistoric objects to determine what year a wine comes from, or its vintage.
