Supplementary Material

In this section, all the data collected on the wine analysed are reported. Values are mean of three independent replications. In Table S1 alcoholic percentage, pH and SO2 concentration are listed. Table S2 reports the values of total phenol, total anthocyanin, total flavonoid and proanthocyanidin indices together with EPR free-radical scavenging activity. Tables S3 and S4 show the values of flavonols and HCTAs concentrations respectively. Figure S1 shows the decrease of the DPPH EPR signal with time after the addition of wine.
