In order to establish the dynamics of the physical-chemical parameters of flavoured wines and vermouth type wines, obtained by the addition of hydroalcoholic macerates from plants to the Sauvignon Blanc wine variety, we analyzed certain physical and chemical characteristics (D 20 20, Alcool %, Total dry extract g/l, Free sugar g/l, Unreducing extract g /l, Total Acidity g/l C4H6O6, Free SO2 mg/l Total SO2 mg/l) for 9 samples. Compared to the main wine parameters, the tested parameters had the following evolution: Alcoholic strength, Free sugar and Density increased in vermouth type wines, Total acidity decreased slightly in flavoured wines and more obvious in vermouth type wines. The total dry extract increased sharply in vermouth type wines and the unreducing extract decreased sharply in vermouth type wines. The amount of Free SO2 was higher in flavoured wines, but Total SO2 had lower values, both for flavoured wines and vermouth type wines, comparative to Sauvignon Blanc wine. Plants macerates added to the Sauvignon Blanc basic wine, influenced most of the physical-chemical parameters and provided new qualitative features to resulting beverages.
