Abstract: SNIF-NMR and IRMS methods were used to determine the stable isotopic ratios of D / H and 18O/16O of wine.The results showed that methylene(D/H)Ⅱ of ethanol in wine,R andδ18O‰ are the key determinants in identifying the geographical origin of wines whereas methyl(D/H)Ⅰsite andδ13C‰ provide less significant information.Using the results of SNIF-NMR alone can only distinguish areas of considerably different environment.If coupled withδ13C‰,the areas with different temperature can be distinguished,but the areas with similar environment still cannot be separated.If combined the values of(D/H)Ⅰ,(D/H)Ⅱ,R,δ13C‰ andδ18O‰,SNIF-NMR and IRMS methods can differentiate areas with similar environment.The research outcome provides a new technique to determine the geographical origins of Chinese wine.
