Abstract: The present application provides a method for tracing wine origin based on multielements and stable isotopes, comprising the steps of: 1) collecting wine samples from a plurality of origins; 2) filtering the wine samples collected in step 1) and using the filtrate for carbon stable isotope ratio analysis of ethanol and glycerol; using the filtrate for analyzing oxygen stable isotopes in water; performing digestion with HNO3 overnight, and diluting to a constant volume to be tested; 3) performing carbon stable isotope analysis, oxygen stable isotope ratio analysis and elemental analysis; 4) utilizing information of the origins of the wine samples and analytical data of step 3) to perform statistical modeling to obtain a wine origin discrimination model coefficient matrix and a corresponding predicted accuracy rate of the origin discrimination; and 5) determining attributes of the wine origin by using the statistical model.

Abstract: The present application provides a method for tracing wine origin based on multielements and stable isotopes, comprising the steps of: 1) collecting wine samples from a plurality of origins; 2) filtering each of the wine samples collected in step 1) using a pore size of 0.22 ?m aqueous filter membrane, and pouring 1.5 ml of a filtrate into an autosampler vial for carbon stable isotope ratio analysis of ethanol and glycerol; pouring 0.3 ml of the wine sample into a 12 ml glass tube with stopper for analyzing oxygen stable isotopes in the water; and pouring 0.5 ml of the wine sample into a 15 ml centrifuge tube, and adding 0.
