International audienceWine traceability has become of primary importance for consumers as well as for producers. Indeed, because of its high market price, it's a product highly subject to fraud. Traceability analysis are, among others, performed by trace element analysis. Indeed, their content may change depending on the soils on which the vine has grown and also as a function of the agricultural practices. But in addition, these different origins may also impact these trace elements speciation. Therefore, the objective of our work was to check if the speciation analysis could be more discriminant than the single total element content for geographical discrimination purpose. In a first step, the development and the validation of the speciation methods of different elements (As, Se) in red wine will be described. Then, the application of these methods to the analysis of red wines from different geographical origin will be presented. Finally, the statistical treatment of these data will allow to the conclusion about the relevancy of using speciation analysis to discriminate the geographical origin of red wines
