Kilning is the process of heat-drying malted barley in a kiln. The process stops germination and produces dry, easily milled malt. Kilning also removes the raw flavour (or green-malt flavour) associated with germinating barley, and new aromas, flavours, and colours develop according to the intensity and duration of the kilning process.
