The aim of this study is to evaluate the usefulness of the mineral analysis of the Romanian white wines for the variety authentication using an ICP-MS method. For this reason were analysed three different varieties of white wines (Chardonnay, Riesling and Feteasca alba) from the same vineyard. The mineral analysis was conducted on 27 elements (Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Sr, Tl, U, V and Zn). It seems that the mineral in higher concentration were Li, Zn, Cu, Be and Ni, so we can conclude that these metals are assimilated different by the vine varieties. The Principal Component Analysis was conducted for achieving the influence of each mineral of the wine type.
