. Samples of Cabernet Sauvignon red wine - from two vineyard areas in Moldova and one in Dobrogea - were bought from local markets and analyzed using ICP-OES. Trace concentrations of Al, Sr and Zn were identified. The lowest concentrations were found in Vrancea wines from the year 2003 and the highest concentrations were found for the Vaslui wines from the year 2007. Potassium concentrations depended strongly on the wine variety and the year of harvest, while iron and sodium concentrations had low variations. All mineral concentrations were below the maximum allowed level stipulated by the "Law on Vine and Wine." One single sample exceeded the maximum allowed sodium concentration by 3 mg L-1.
