“Grainy, like germinating malt”
Beer flavour standard used to train professional beer tasters to recognize and scale the intensity of grainy character.
Isobutyraldehyde and related compounds arise in beer through use of pale malts and certain brewhouse procedures. This is a key flavour impact character in some lagers and ales, an off-flavour in low alcohol beers, and a signature flavour character in some stouts.
