Draft systems are often out of sight, out of mind — but small oversights behind the bar can quietly drain revenue. Many bars lose money not because of poor product, but because of preventable draft system mistakes.
One of the most common issues is improper line cleaning. Infrequent or inconsistent cleaning leads to buildup that affects taste, increases foam, and causes wasted pours. Every foamy pint is essentially money down the drain.
Another costly mistake is incorrect gas selection or pressure settings. Using the wrong gas blend — or running pressure too high or too low — can result in flat beer, excessive foam, or inconsistent carbonation. These issues not only waste product but also impact the customer experience.
Poor temperature control is another hidden culprit. Warm beer lines or improperly cooled towers cause excessive foaming, forcing bartenders to over-pour and discard product. Even a few degrees off can make a noticeable difference.
Finally, many bars delay routine maintenance until something breaks. Small leaks, worn seals, or aging components often go unnoticed until they cause major disruptions — or emergency service calls.
But there’s good news! These problems are entirely preventable. Regular maintenance, proper system design, and ongoing service ensure every pour is consistent, efficient, and profitable.
A well-maintained draft system isn’t just about quality — it’s about protecting your bottom line.
