  • Observations regarding the SNIF-NMR method for improving its applicability for the wine control in the EC : Comparison of various distillation systems


In order to control the addition of illegal sugars to wines in the EU, analytical techniques are employed which can measure the occurence of isotopes such as deuterium and hydrogen. This allows the identification of the sugar present in the original must. The distillation of ethanol from wine is a critical step of the sample preparation since isotopic fractionation can lead to a final distillate with isotopic ratios that are not representative of the original alcohol. This paper compares the use of different distillation systems in European Union laboratories. A wine sample and two simulated wine samples are used and the results compared to the standard conditions which have been applied in various laboratories over the years.
