Forest where wine barrels came from possible to identifty by mass spectrometry

Researchers at the university of bourgogne in Dijon in france chose 9 forests whose oak trees have been used to make wine barrels, and identified wines which had aged in wood from those forests.

Mass spectrometry then identified the chemicals in an ionised sample of each wine and found that each forest left its chemical peculiarities in the wine's signature.

The technique could be used to authenticate wine origins
