Most bars should have their beer lines professionally cleaned every 4 weeks. This is the industry standard and helps prevent buildup that affects taste, causes foaming issues, and leads to wasted product.

Dirty beer lines develop yeast, mold, and bacteria buildup. This leads to off-flavors, inconsistent pours, excessive foam, and unhappy customers.

Foam is usually caused by dirty lines, incorrect pressure, temperature issues, or improper line balancing. Cleaning is often the first step to fixing the problem.

Absolutely. Even slightly dirty lines can give beer a sour, buttery, or stale taste. Clean lines are critical to serving beer the way it was intended.
