Channelling occurs when too little water is added during the sparge to replace the water that is being drawn off. As a result, the grain bed becomes compacted, and water flows only through a few channels, rather than filtering through the grain bed. As a result, less of the grain is exposed to the wort, resulting in a lower specific gravity in the final wort.
