What is the recommended frequency for cleaning a draft system to prevent off flavors in beer?

Cleaning a draft system every 14 days is recommended to effectively prevent off flavors in beer. This frequency is crucial because beer lines can accumulate yeast, bacteria, and other residues that not only affect the flavor but also the quality and safety of the beer served. Regular cleaning ensures that these contaminants do not reach the consumer, allowing for a fresh and enjoyable product.

Cleaning every 14 days addresses the fact that beer can be susceptible to spoilage quickly when introduced to unclean environments. Factors such as temperature, the type of beer being served, and the volume of beer dispensed all contribute to how quickly deposits build up in the lines. The two-week interval strikes a balance that helps maintain optimal hygiene and beer quality, ensuring that patrons have a consistently good experience.

Longer intervals, such as 30 or 60 days, may lead to increased risk of off flavors developing, making the 14-day recommendation the most effective for maintaining the beer’s intended flavor profile.
