Content of elements in untreated and treated with bentonite clays wines

Data on the concentrations of macroelement (Na, K, Ca and Mg) and microelement (Zn, Cu, Rb, Ge, Mo, Li, Pb, Zr, Cd, Nb, Co and Be) in the untreated and bentonite-treated wines are presented in the table. The data provide insight into the interaction of bentonite clays of various nature with wine samples and the procedure for the exchange of elements during the formation of their elemental composition. The data allow to assess the contribution of claying agents to the elemental composition of wines and establish marker elements that determine their varietal affiliation.
