Abstract: The contents of five metals (Cu, Mn, Fe, Cd, and Pb) in several red and white wines originating from different regions of Serbia were determined by flame and graphite furnace atomic absorption spectrometry. The data were processed us- ing chemometric techniques. Principal component and factor analysis were applied in order to highlight the relations between the elements and, after data reduction, three main factors controlling variability were identified. Application of hierarchical cluster analysis to the studied wines indicated differentiation of the samples belonging to different origins. No discrimination between red and white wines was found.

Elemental patterns of wines, grapes, and vineyard soils from chinese wine-producing regions and their association
TL;DR: Wang et al. as discussed by the authors analyzed 28 trace elements and 16 rare earth elements through ICP-MS in soils, grapes, and wines from seven wine-producing regions in China, and found that almost all elements in the grapes and wines and approximately half of the tested elements existed in statistically significant different amounts on a regional basis.
