1 Scope
This European Standard specifies an isotopic method to control the authenticity of
wine vinegar. This method is applicable on wine vinegar in order to characterise the
18O/16O ratio of water, and allows differentiating wine vinegar from vinegars made from
raisins or alcohol vinegar.
NOTE The Oxygen 18 isotopic analysis of water from vinegar is based on a similar method already normalised for wine analysis [2].
