What are the two primary goals of cleaning a draft beer system?

The primary goals of cleaning a draft beer system revolve around maintaining the integrity and quality of the beer served. One essential objective is to remove organic material and mineral deposits. Over time, beer lines can accumulate residues from yeast, hops, proteins, and other organic matter, as well as mineral build-up from the water used in brewing. If left uncleaned, these residues can negatively impact the taste, mouthfeel, and overall quality of the beer.

By regularly cleaning the draft system, the likelihood of off-flavors is reduced, ensuring that customers enjoy the intended characteristics of the beer. Clean lines contribute significantly to the maintenance of flavor integrity while also preventing potential bacterial growth and contamination that may arise from accumulated organic matter. Therefore, the focus on the removal of these residues is critical in preserving not just the cleanliness but also the overall beer experience at the tap.
