How often should draft lines be changed?

Changing draft lines is an essential aspect of maintaining draft beer quality and ensuring good hygiene practices in a bar or restaurant setting. The recommended frequency for changing or cleaning draft lines is typically once every two weeks. This interval helps to prevent the buildup of yeast, bacteria, and other contaminants that can affect the flavor and quality of the beer.

Draft beer systems can develop biofilm and deposits that negatively impact the taste and clarity of the beer if not cleaned regularly. By adhering to a two-week cleaning schedule, establishments can maintain optimal draft beer freshness, enhance customer satisfaction, and ensure compliance with health standards.

A daily change would be excessive and impractical for most operations, while a weekly schedule, although better than longer intervals, may still allow for undesirable buildup. Monthly cleans would likely be insufficient to maintain beer quality, leading to potential spoilage and hygiene issues. Therefore, a bi-weekly interval strikes a balance between effective maintenance and operational feasibility.
