How often should vinyl lines in direct draw systems be replaced?

In a direct draw system, the frequency of replacing vinyl lines is crucial for maintaining beer quality. Vinyl lines can accumulate bacteria, yeast, and other pathogens over time, which can negatively impact the flavor and hygiene of the beer being served. By replacing the lines every year, you ensure that any build-up is kept to a minimum, thereby reducing the risk of off-flavors and contamination. This practice helps ensure that the beer maintains its intended flavor profile and freshness, crucial for optimal service in a quality-focused establishment.

While the other options might seem reasonable, they either fall short of providing enough rotation to maintain quality—such as every two years or every five years— or may be excessive for certain operations that don’t have high turnover, like every six months. Annual replacement strikes a balance between maintenance and practicality for most establishments, allowing for effective cleaning and minimizing potential issues related to line sanitation.
