Abstract

Wine is a very complex mixture of a large number of compounds, including phenolics (anthocyanins, flavan-3-ols, flavonols, phenolic acids, stilbenes), volatiles (alcohols, esters, aldehydes, volatile phenols), minerals (Al, Zn, Cu, Fe, Pb), organic acids, carbohydrates, proteins, vitamins etc. All these compounds significantly influence the quality of wine, affecting the sensory perception such as flavor, aroma and colour, pH, chemical and microbiological stability of wines. Their amount in wine depends on various factors such as grape variety, environmental factors, ripening stage, vine cultivation and winemaking practices applied for wine production. The winemaking process is one among these factors that can be controlled, and mainly includes a range of modifications during fermentation and maceration, such as fermentation temperature, yeast strain, racking duration, type of lees, etc. This paper summarize the results obtained for phenolic, volatile and elemental composition of Macedonian wines, commercial as well as wines produced under different winemaking techniques, analyzed with the most sophisticated techniques such as HPLC-DAD-ESI-MS/MS, MALDITOF-MS, CZE-ESI/QTOF-MS, HS-GC-MS and ICP-MS [1-10]. Obtained results give us new information about the quality of wines, which is important to support the viticulture and wine strategy in Macedonia as well as to increase the competitiveness of Macedonian wines on the global market as products with specific quality characteristics, such as high content of phenolics and antioxidants, rich in color and aroma.
