Question: 1 / 400

Why must draft lines be cleaned regularly?

To enhance flavor

To prevent bacterial infection

Regular cleaning of draft lines is crucial primarily to prevent bacterial infection. Over time, residues from beer can build up in the lines, creating an environment conducive to the growth of bacteria and yeast. These microorganisms can produce off-flavors, spoil the beer, and even lead to health issues for consumers.

Additionally, while flavor enhancement, carbonation improvement, and maintaining clarity are important aspects of draft beer service, they are secondary to the primary goal of preventing contamination. If bacteria are allowed to flourish in unclean lines, they can not only spoil the beer but also impart undesired flavors and aromas that detract from the overall experience. Regular maintenance and sanitation of draft systems ensure the beer remains fresh, safe, and enjoyable for consumers.
