Summary:This article summarizes results of the study of geochemical characteristics of Slovak vineyard regions for the purposes of geographical wine authentication. A model for the prediction of geographical origin of wines which uses the specific elemental and discriminant analysis was proposed on the basis of geochemical characterization of soils of 6 Slovak vineyard region (Small Carpathian, South Slovakian, Nitra region, Central Slovakian, Eastern Slovakian and Tokaj region). The model was verified on real samples of grapes and soils from the mentioned vineyard regions. For the geographical authentication following elements were selected due to their variability: rubidium, lithium, barium, strontium, arsenic, calcium, cobalt, chromium, magnesium, tin and vanadium. Differentiation of vineyard regions was done by the Principal Component Analysis (PCA). Selected elements were analysed by methods of atomic absorption spectrometry (AAS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES).
