The best way to clean beer lines is through a process called acid cleaning. Acid cleaning should be performed on a quarterly basis to remove any inorganic compounds that can build up in the lines, such as “beer stone.” This is essentially a mineral deposit that can form over time and negatively impact the quality and taste of the beer.
To begin the acid cleaning process, it is important to first disconnect the beer lines from the keg or tap system. This will allow for easier access to the lines and ensure a thorough cleaning. Next, prepare a solution of acid cleaner according to the manufacturer's instructions. There are various types of acid cleaners available on the market, so it is important to choose one that is specifically designed for beer line cleaning.
Once the acid cleaner solution is prepared, it can be circulated through the beer lines. This can be done using a hand pump or a cleaning kit specifically designed for beer line cleaning. The acid cleaner should be pumped through the lines for a sufficient amount of time to ensure thorough cleaning. This usually ranges from 15 minutes to an hour, depending on the severity of the buildup.
After the acid cleaner has been circulated through the lines, it is important to thoroughly rinse them with clean water. This will help remove any remaining traces of the acid cleaner and ensure that no residue is left behind. The lines can be rinsed by pumping clean water through them using the same method as the acid cleaning process.
In addition to regular acid cleaning, it is also recommended to replace all vinyl jumpers and vinyl direct draw lines on an annual basis. This will help prevent any potential contamination or buildup that may occur over time. It is important to note that vinyl lines can degrade and become more susceptible to bacterial growth, so regular replacement is necessary to maintain cleanliness and quality.
Furthermore, couplers should be replaced based on their condition. If a coupler shows signs of wear, such as leakage or difficulty in connecting, it is advisable to replace it to ensure proper functioning and to prevent any potential contamination.
The best way to clean beer lines is through regular acid cleaning on a quarterly basis. This process helps remove inorganic compounds such as beer stone and ensures the cleanliness and quality of the beer being served. Additionally, replacing vinyl jumpers and vinyl direct draw lines annually, and couplers based on their condition, is essential to maintaining a clean and well-functioning beer dispensing system.
