Using NMR to Authenticate Spanish Wine

This article reports a recent webinar to discuss the role of NMR in the non-targeted authenticity analysis of wine, and in particular Spanish wine. The NMR analysis is able to identify and quantify several hundred compounds present in the wine. Reference databases have been built up of these compound profiles using authentic wine, and these are used on wine samples to verify whether they are authentic or not. The method has been adopted by the  Estación Enológica de Haro (EEH) part of the Institute of Vine and Wines Sciences in La Rioja, which serves the wine industry across Spain, and analyses 25,000 samples annually and conducts around 263,000 analyses every year from private clients.
