Draught beer line cleaning is a critical factor in the service of
excellent draught beer. Cleaning your system frequently ensures beer
quality but increases the cost of service due to beer lost when
preparing the lines for cleaning. Throughout the industry, there is
debate over the "best practices" in draught cleaning, including what
defines a "clean" draught system. With the ever-increasing selection of
draught beers, it is imperative not only to the brewer but all the way
to the consumer that the beer provided as draught is representative of
the beer provided by the brewer. The challenges of clean beer lines have
never been more evident than today. Many of the draught beers on the
market come with active yeast cultures, wild yeast cultures, and
bacteria, all part of the flavor mix. These organisms can contaminate
draught lines for the next beer to be tapped on those lines.
Additionally, the intrusion of contaminant microorganisms from various
sources and breweries needs to be eliminated and controlled within
draught systems to ensure that the beer poured is exactly as intended.
