3. Conclusion

Isotopic analysis is a powerful tool for checking wine authenticity. This tool is all the more effective when it is based on a database of authentic samples and/or a comparison between a control sample and a suspect sample. New applications of NMR are opening up new avenues in food control, as are new couplings such as liquid chromatography with IRMS spectrometry: profiles or isotope ratios are markers of wine authenticity. Finally, the use of mathematical models based on multidimensional statistical analysis of the results of isotopic analyses coupled with those of spectral profiles (NMR, Raman
