There were significant effects of SO2 level on the AN composition in the wines of this experiment, with more ANs extracted in wines with higher SO2 level. The percentage distribution of AN composition was not affected by the treatments, while extraction and ionization of total and individual ANs were always higher when only sulphur dioxide was used. The same pattern followed the concentration of TPs and Fs. Antioxidant activity values also showed a similar trend, where the higher values were observed in the wines containing only SO2
