This study examines the variations in isotopes and trace elements in relation to grape variety, environmental factors and provenance in order to address the wine authenticity in Cyprus. ICP-AES assessed the wines’ elemental content. SNIF-NMR and isotope ratio mass spectrometry methodologies determined in authentic and commercial wines the distribution of the naturally occurring stable isotopes of the deuterium/hydrogen (D/H) ratios and carbon (13/12C) in ethanol of wine and oxygen ratio (18/16O) in wine water. PCA (principle component analysis) highlighted the importance of grape variety and provenance, while supervised analysis pinpointed the vineyard effect and highlighted the contribution of the vintage year. These results can be incorporated to the EU Wine Isotopic Databank database providing both a guide and a tool for eventual candidatures for denomination of origin and support both Cypriot wine and winemakers.Read the abstract at: http://link.springer.com/article/10.1007/s12161-017-0959-2
