Authenticity of food products is one of the most important issues in order to control product quality and consumer and producer safety. Consumers expect the quality and origin to conform to the label that describes the product according to the relevant legal provisions. Due to the possibility of applying various methods of counterfeiting food products, it is necessary to develop a method for determining their authenticity. Wine is a product that can be counterfeited by various methods of adding certain ingredients to wine (eg Water, Glycerol, Alcohol, Sugar, Sweeteners, Colors, Aromas, Preservatives etc.) to manipulation regarding variety, vintage and geographical origin. In order to determine the authenticity of wines, various methods have been developed based on the determination of volatile compounds, amino acids, phenolic compounds, mineral composition, isotope ratios. In this paper, based on the mineral composition of wine, we conducted a research aimed at determining the authenticity of wines based on their geographical origin, variety and vintage. Wines are produced according to the EU official protocols for the production of authentic wines. The research included grape wines from 2009-2012, produced by six of the most important cultivars of Vitis vinifera L. represented in the wine-growing region of the Republic of Croatia. Determination of mineral composition is carried out in ICP-OES technique. The obtained results showed that the wines examined differed with respect to the share of certain macro and micro elements in terms of their geographical origin, variety and year of harvest.
