Managing the microbiological risk

There is little debate that line cleaning is the key parameter in the assurance of draught beer quality. Whilst the tap and the keg coupler are clearly contributors to dispense system hygiene, they receive comparatively little attention, and what there is (i.e. spout cleaning), can exacerbate the problem. 

On the face of it, fine cleaning is a straightforward process involving the regular use of proprietary (usually) caustic-based cleaners to remove biofilms from surfaces. Inevitably and regrettably, it is not that simple rather, too many tunes can be played, with consequent damage to system hygiene and beer quality.
