How to Properly Clean and Maintain Your Beer Lines

As the owner of a craft beer business, I understand the importance of serving the best quality beer to my customers. One critical aspect of ensuring the quality of our beer is by properly cleaning and maintaining our beer lines. Neglecting this task can lead to dirty beer lines, which can impact the taste, aroma, and appearance of the beer. In this article, I will share the recommended guidelines for beer line cleaning and maintenance.

Why is Beer Line Cleaning Important?

Beer line cleaning is essential to maintain the quality of the beer being served. Dirty beer lines can lead to a host of issues such as off-flavors, hazy appearance, and a decrease in carbonation. The buildup of bacteria, yeast, and mold in the lines can also cause health concerns.

To ensure the quality of our beer, we prioritize regular cleaning of our beer lines. This task is critical to provide customers with fresh, high-quality beer.

When Should Beer Lines be Cleaned?

The frequency of beer line cleaning can vary based on factors such as usage, temperature, and type of beer. However, we recommend cleaning beer lines every two weeks at a minimum. If the lines are being used more frequently, then more frequent cleaning may be necessary.

There are some signs to watch for that indicate beer lines need to be cleaned. These include an off-flavor in the beer, a decrease in carbonation, or a cloudy appearance.

How to Clean Beer Lines

Cleaning beer lines requires some supplies such as a cleaning solution, a cleaning bottle, and a faucet brush. We use a two-step process to ensure that our beer lines are thoroughly cleaned.

Step 1: First, we flush out the beer lines with water to remove any remaining beer.

Step 2: Next, we use a cleaning solution such as BLC (Beer Line Cleaner) or PBW (Powdered Brewery Wash) to thoroughly clean the lines. We fill a cleaning bottle with the cleaning solution, attach it to the keg coupler, and run the cleaning solution through the lines. We let the solution sit in the lines for a recommended amount of time (as per the cleaning solution instructions) before flushing it out with water. Finally, we run a sanitizer solution through the lines to ensure they are completely clean.

Maintaining Beer Lines

Regular maintenance of beer lines is also essential to keep them clean between cleanings. Here are some tips to help maintain beer lines:

  • Keep the beer lines cold to prevent the growth of bacteria.
  • Keep the beer lines pressurized to prevent oxygen from getting into the beer.
  • Clean the faucet regularly with a faucet brush to remove any buildup.
  • Avoid using copper fittings, as copper can react with beer and cause off-flavors.
  • Use line cleaning pumps to clean lines more efficiently and thoroughly.

Regular maintenance of beer lines can help prevent the buildup of bacteria, yeast, and mold, which can lead to dirty beer lines and off-flavors.


Properly cleaning and maintaining beer lines is critical for serving high-quality beer. Neglecting this task can lead to dirty beer lines and a decrease in beer quality. Regular cleaning and maintenance can help prevent this, and ensure that customers receive the best quality beer possible. As a craft beer business owner, I prioritize the regular cleaning and maintenance of our beer lines, and I encourage others in the industry to do the same.
