The effect of adding sulfite during the mashing has also been examined. Addition of sulfite could potentially give a wort with a high level of polyphenols in different ways. First, it may act as an antioxidant at the early stages of production of beer, thereby preventing oxidation of polyphenols during wort handling, resulting in wort and beer with a high level of proanthocyanidins. Second, sulfite has been shown to reduce and thereby regenerate oxidized flavonoids in model experiments (13).<ref name=andski>Andersen ML, Skibsted LH.
