bordeaux wine authenticity (2)


This report from the Norwegian Research Institute Nofima, and one of the research outputs of the EU Project EU-China Safe, examines the supply chain from the Bordeaux region in France to China to try and identify where discrepancies in the recorded traceability data and points of weakness might occur in order to indicate vulnerability to possible fraud. The mapping and analysis of the supply chain, and the indication of where fraud might happen was partly based on existing scientific literature, reports, and news stories, and partly on a number of interviews conducted with supply chain actors in France and in China. The limitations of this report relate to the fact that the study has focused solely on the Bordeaux wine trade between France and China. Access to respondents for the study was limited, even if the data collected was complemented with both primary and secondary data sources. Because the wine supply trade is quite complex, it is acknowledged that there are many more perspectives along the local-in-global supply chain that have not been reflected in this report. However, this study will contribute to the growing body of academic literature and discussion to inform governance structures for the cultivation of a more secure food trade and traceability between Europe and China in general.

Bordeaux wines are highly valued and sought after, and hence vulnerable to counterfeiting. French reseachers have used strontium concentration and strontium isotope ratios as markers for Bordeaux wine geographic origin and authenticity. Forty three authentic Bordeaux wines were collected from the world’s most prestigious Bordeaux châteaux. The Sr elemental composition and 87Sr/86Sr ratio were determined on these authentic wines. The results demonstrated relatively small variabilities for 87Sr/86Sr ratio and Sr concentrations in the authentic Bordeaux wines, which can be used with reasonable certainty to identify regional Bordeaux wineries and distinguish them from counterfeit wines.
