Isotopic analyses of wine and of products derived from grapes
The nuclear magnetic resonance method for the measurement of the enrichment of wine with sucrose and the method for the detection of watering, based on the measurement of the oxygen-18 content of wine, have been adopted by the European Union in 1990 and 1997 respectively. Meanwhile other isotopic methods have been developed to check the authenticity of grape products. The determination of the carbon-13 content of ethanol of wine for checking the addition of cane sugar will be adopted soon. Isotopic methods for control of sparkling wines, glycerol and vinegar are under investigation and will be tested by interlaboratory trials.
