A direct measuring method for the determination of mineral components in grape wine by Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) was developed. It was applied to six grape wines from China’s 2 major wine-producing regions-Changli in Hebei Province and Yantai in Shandong Province. Here in this study, eleven elements (Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Ni, Pb and Zn) were analyzed. The analysis was performed by heating the wine sample in an oven with acid digestion method using concentrated nitric acid (HNO_3) and perchloric acid (HClO_4), followed by sequential determination of the elements by ICP-OES. Typical patterns of elements obtained by the multicomponent analyses can be evaluated by multivariate data analysis to recognize the wine origins.
