To use draft beer line cleaner, it is important to follow the guidelines recommended by the Brewers Association (BA) draught beer quality beer manual. This manual is a valuable resource for maintaining the quality of draft beer and ensuring clean beer lines.
The first step is to determine the condition of the beer lines. If the lines are well-maintained and in normal condition, it is recommended to use a solution of 7 ounces of draft beer line cleaner per gallon of water. This creates a 2% caustic solution, which is effective in regular cleaning.
However, if the lines are neglected or stubbornly dirty, a stronger solution is required. In such cases, the manual suggests using a solution of 11 ounces of draft beer line cleaner per gallon of water. This creates a 3% caustic solution, which is more powerful and can effectively tackle tough buildup and residue in the lines.
Now, let's dive into the process of using draft beer line cleaner. Here are the steps to follow:
1. Prepare the cleaning solution: Measure the appropriate amount of draft beer line cleaner according to the condition of the lines. For normal conditions, use 7 ounces per gallon of water (2% caustic). For neglected lines, use 11 ounces per gallon of water (3% caustic). Mix the cleaner thoroughly in a container or bucket.
2. Disconnect the beer lines: Before starting the cleaning process, it is crucial to disconnect the beer lines from the keg or tap system. This ensures that the cleaning solution can flow freely through the lines without any interference.
3. Flush the lines: Using a cleaning bottle or a pump, flush the beer lines with clean water to remove any residual beer or debris. This initial flush helps to prepare the lines for the cleaning solution and ensures better cleaning effectiveness.
4. Pour the cleaning solution: Once the lines are flushed, pour the prepared draft beer line cleaner solution into the cleaning bottle or pump. Attach the bottle or pump to one end of the beer line, making sure it is securely connected.
5. Circulate the cleaner: Start pumping the cleaning solution through the beer lines, allowing it to circulate and clean the entire length of the lines. The cleaning solution should be circulated for a recommended duration, which may vary depending on the level of buildup and residue. Consult the manual for specific guidelines on the cleaning time.
6. Rinse the lines: After the recommended cleaning duration, flush the lines again with clean water to remove the cleaning solution and any loosened debris. This step is essential to ensure that no traces of the cleaner remain in the lines, as it can affect the taste and quality of the beer.
7. Reconnect and test: Once the lines are thoroughly rinsed, reconnect them to the keg or tap system. Run a small amount of beer through the lines to ensure that they are clean and free from any residual cleaning solution. If the beer flows smoothly and tastes fresh, it indicates that the cleaning process was successful.
Remember, regular cleaning and maintenance of draft beer lines are essential to preserve the quality and taste of the beer. Neglected lines can lead to off-flavors, foaming issues, and bacterial contamination. By following the recommended guidelines and using draft beer line cleaner effectively, you can ensure a clean and enjoyable draft beer experience for yourself and your customers.
In my personal experience as a brewer, I have encountered situations where neglected beer lines resulted in significant quality issues. The flavor of the beer was compromised, and customers complained about excessive foaming and off-tastes. It was a valuable lesson that highlighted the importance of regular line cleaning and maintenance.
By using draft beer line cleaner correctly and consistently, I have seen a noticeable improvement in the taste, aroma, and appearance of the draft beer. It is a simple yet vital step in the brewing process that should never be overlooked.
