you can remove sulfites by adding hydrogen peroxide to your wine
Still want to get rid of sulfites? In theory, you can remove sulfites by adding hydrogen peroxide to your wine. I don’t recommend it but I mention it only because I keep getting asked how to do this. The correct amount to add will depend on the sulfite level in the wine, an amount you cannot deduce except by chemical analysis. However, for the typical wine at 80 mg/L sulfites, 1 milliliter of 3% hydrogen peroxide, the form sold in pharmacies, will remove the sulfites in one bottle of wine. If you want to learn more, there is a study of the reaction between sulfite and hydrogen peroxide in simple water solutions: M.R. Hoffman and J.R. Edwards, Kinetics of the Oxidation of Sulfite by Hydrogen Peroxide in Acidic Solution, J. Phys. Chem. 79: 2096 (1975) Link Hydrogen peroxide has been used to remove sulfites from cucumbers and dried fruit. Ozkan, M; Cemeroglu, B. 2002. Desulfiting dried apricots by hydrogen peroxide.
