Grainy Beer Flavour Standard
Importance of the Grainy Beer Flavour Standard
In the main Grainy is an undesirable character, but may feature at a low level in some beers.
Origins of flavour
The grainy flavour note is imparted to beer by the use of barley malt and controlled by sparging and wort boiling practices. Also associated with the use of malts that have not been stored for long enough before use.
Remarks
In addition to isobutyraldehyde, other aldehyde’s contribute to the grainy flavour of beer.
