Sulphitic Beer Flavour Standard
Importance of the Sulphitic Beer Flavour Standard
Associated with the presence of sulphites in beer. Sulphites interact with other flavour compounds in beer, including acetaldehyde and carbonyl compounds, to mask their flavour.
Origins of flavour
Sulphites may be added to beer as an antioxidant or preservative. Lager yeasts naturally produce sulphite during fermentation.
Remarks
Recommended standard of ASBC and the EBC.
Some asthmatics are hypersensitive to sulphites. Check that all people tasting this standards have no history of asthma.
