Abstract

The analytical method adopted by the CEC to detect wine chaptalisation is based on the determination of the deuterium content of the isotopomers in wine ethanol by the SNIF-NMR method. Since the natural deuterium content of the wine is influenced by various factors, e.g. the geographical origin of the grapes and the climatic conditions, the JRC-Ispra was commissioned to create a data bank of isotopic NMR data on reference wines from the EC. Current experience and results of important influences concerning the proof of chaptalisation, reproducibility of the method and analytical tasks associated with the creation of the data bank are discussed.
