Papery Beer Flavour Standard
Importance of the Papery Beer Flavour Standard
Papery is an off flavour in beer associated with ageing.
Origins of flavour
The papery flavour note is formed during beer storage. Development of character depends of time and temperature of storage and oxygen of packaged beer.
Remarks
Sulphites interact with trans-2-nonenal in beer, resulting in a loss of the papery character of this substance.
