Essentials of Beer Line Cleaning

Maintaining clean beer lines is crucial for ensuring the quality and taste of draft beer. Proper cleaning eliminates contaminants that can cause off-flavors and spoilage, and it also prevents the build-up of yeast and bacteria.

Cleaning Frequency

Regular cleaning is essential to maintain the quality of the beer. The Brewers Association recommends cleaning draught lines at least every two weeks. More frequent cleaning may be necessary depending on the volume of beer dispensed and the types of beers served, as some beers may leave more residues than others.

Recirculation With Electrical Pump

Required Cleaning Equipment

A variety of cleaning kits are available, designed to suit different systems. a kit Essential equipment typically includes a cleaning pump or tank, a faucet wrench, a faucet brush, and a variety of cleaning adapters to ensure all areas of the system are reached. Using the right brushes and maintaining them is vital for effective cleaning.

Recirculation Cleaning

Recirculation systems use an electric pump to send the cleaning chemical through the lines. Recirculating the solution for at least 15 minutes improves contact time and effectiveness, ensuring thorough cleaning. It’s the most efficient method for establishments with long-draw draught beer systems. Direct Draw systems and Air-Cooled Systems.

Choosing the Right Cleaning Solution

It's critical to select a cleaning solution that is appropriate for the materials used in beer lines and other components of the draught system. Solutions should be strong enough to remove build-up but safe for use with the equipment. Always follow with an adequate rinse to ensure no cleaning solution remains in the lines.

Step-by-Step Beer Line Cleaning Process

Maintaining the quality of beer served in commercial establishments requires a serious effort and meticulous, regular cleaning of the beer lines. This process helps to ensure the beer remains fresh and free from contaminants that can affect flavor and safety.

Preparing the Cleaning Solution

The first step in the beer line cleaning process is to prepare the cleaning solution. One must use a beer line cleaning kit, which specifically includes a beer line cleaning solution that is designed for this purpose. The instructions on the beer line cleaning kits and the solution must be followed carefully, typically involving diluting the concentrate with water to achieve the correct ratio for effective cleaning.

Flushing and Rinsing the Lines

After the solution is prepared, flushing the beer lines clean is next. Begin by disconnecting the beer kegs and attaching the cleaning keg couplings. Then, the cleaning solution is pumped through the lines to remove any buildup of beer stone and other contaminants. The Brewers Association recommends running the solution through for a time of 15 minutes which ensures the entire length of the beer line is contacted with the cleaner. Once the lines have been thoroughly cleaned, they should be flushed with clean, cold water to rinse any residual cleaner from the lines, ensuring no cleaning solution is left that might affect the taste or safety of the beer. To verify the solution is out of the beer system. Use Ph paper and make sure it's neutral or at number 7 color.

Flushing and Using pH Paper

A critical part of the beer line cleaning equipment and process is confirming that the lines have been rinsed properly. Using pH paper to test the acidity or alkalinity of the residue water inside the lines is essential. This allows one to compare the pH level of the water from the draft system to that of the tap water to ensure they are similar, indicating that the lines are successfully rinsed and are free of cleaning solution. Proper maintenance dictates multiple flushings may be required to return the pH to a neutral level, as detailed in The Basics Of Beer Line Cleaning.

By following these steps, establishments can conduct thorough maintenance of their beer dispensing systems, ensuring a consistently high-quality drink product for their consumers.

Maintaining Your Draft Beer System

Maintaining a draft beer system is critical not only to serving quality beer but also the best way to ensure the longevity of the equipment. Regular cleaning and inspection can prevent the buildup of biofilm and beer residue, which could cause off-flavors and affect the beer's quality.

Regular Maintenance Practices

Draft Systems: At the core of regular maintenance is the cleaning of the beer lines. Industry standards suggest that the tap lines should be cleaned at least every two weeks. This involves using a cleaning solution that is appropriate for the system—typically a 2% - 3% sodium or potassium hydroxide at a temperature between 80°F to 110°F. The solution should be recirculated or left to soak for at least 15 minutes to ensure thorough contact time.

  • Kegerators: Should receive the same level of attention as commercial systems. After disconnecting, they should be cleaned following each keg swap.
  • Faucets: Require disassembly and manual cleaning to remove any buildup of yeast and sugar deposits. Using a spanner wrench to remove the faucet is recommended for thorough cleaning.
