Since the last decade of the 20th century, there has been rising interest in the production of fruit wines, as evidenced by the high number of published papers and books covering this matter. When aiming to produce quality fruit wines, it is essential to evaluate the analytical parameters of the beverage. In this context, there are a large number of analyses for the evaluation of wines and fruit wines. This article characterizes the fruit wines made from different fruits using selected parameters (BAs, metals, sulfates, phosphates) by the use of a traditional chemometric technique – hierarchical cluster analysis. To determine the organic compounds, an in situ derivatization coupled with dispersive liquid-liquid microextraction (DLLME) and gas chromatography–mass spectrometry (GC–MS) was used. The spectroscopy techniques such as flame photometers, AAS and GF-AAS were applied to determine the selected metals content. Wine made from grapes coming from Polish Vineyard (ANNA de Croy) were also analysed to compare the obtained results. The classification offered allows the identification of unknown wine samples with similar origin to be ordered in some of the patterns formed
