The zinc content of different types wines from Znojmo region was determined by differential pulse anodic stripping voltammetry without sample pre-treatment. 45 different wines were analysed. Almost all samples of wine contained less than 1.5 mg/l of zinc (from 0.05 to 3.71 mg/l). The mean zinc concentrations were 1.01 and 1.17 mg/l for white and red wines, respectively. The average of zinc level in sparkling and fortified wines were 1.44 and 1.21 mg/l respectively.
