The article describes the role of sulphur dioxide in beer, being active as an antioxidant, an antimicrobial substance or a substance disguising stale beer flavour. There have been described its forms of occurrence in beer, concentrations commonly occurring in beer, including legislative restrictions. The article also describes the mechanism of its formation during fermentation as well as the factors influencing the mechanism and its decrease during storage.The article describes the role of sulphur dioxide in beer, being active as an antioxidant, an antimicrobial substance or a substance disguising stale beer flavour.
