As an experienced sommelier and brewer, I can confidently say that regular cleaning of beer lines is crucial for maintaining the quality and taste of your draft beer. The frequency at which you should clean your beer lines depends on how often you use your tap system, but a general guideline is to clean them every two weeks if they are in regular use.
However, even if you are not using your tap lines frequently, it is still important to clean them at least once every six weeks. This is because beer lines can harbor bacteria, yeast, and other contaminants that can affect the flavor and aroma of your beer if left unchecked.
Now, I understand that cleaning beer lines can be a time-consuming and tedious process, but trust me, it's worth it. Not only does regular cleaning help ensure the quality of your beer, but it also prevents clogs and other issues that can arise from the buildup of sediment and residue in the lines.
Ideally, I would recommend cleaning and sanitizing your tap lines between each keg you serve on your draft system. This not only ensures that you start with a clean slate for each new beer, but it also makes your life easier in the long run. By cleaning your lines between kegs, you avoid the need for a deep and thorough cleaning later on, which can be more time-consuming and require more resources.
When it comes to the actual cleaning process, there are a few different methods you can use. The most common method is to flush the lines with a cleaning solution, such as a beer line cleaner or a mixture of water and a mild detergent. This solution should be circulated through the lines for a set period of time, usually around 15-20 minutes, to ensure thorough cleaning.
After the cleaning solution has been circulated, it is important to rinse the lines with clean water to remove any remaining residue. This can be done by simply running water through the lines until it runs clear. It is crucial to ensure that all traces of the cleaning solution are removed, as any residue can affect the taste of your beer.
Once the lines have been cleaned and rinsed, it is important to sanitize them to kill any remaining bacteria or yeast. This can be done by circulating a sanitizing solution, such as a diluted bleach solution or a commercial beer line sanitizer, through the lines for a few minutes. Again, it is important to thoroughly rinse the lines with clean water after sanitizing to remove any traces of the sanitizer.
Regular cleaning of beer lines is essential for maintaining the quality and taste of your draft beer. While the frequency of cleaning depends on usage, a general guideline is to clean them every two weeks if they are in regular use, or at least once every six weeks if they are not frequently used. Cleaning between each keg is highly recommended to make your life easier and to ensure the best possible beer experience. So, don't neglect your beer lines, take the time to clean and sanitize them regularly, and enjoy your perfectly poured draft beer!
