SO2 Reduction



Use this calculator to calculate the volume of H2O2 solution to add


After the H2O2 addition,wine should be allowed to equilibrate for several hours before any confirmation analysis of the concentration of remaining SO2 in the wine. Hydrogen Peroxide (H2O2) is a powerful oxidizer and it should be added slowly to the wine in a dilute form to avoid oxidation.
