Dirty Keg Lines – Importance of Cleaning Beer Lines
Kegs are stored in a keg fridge. The location of this keg fridge is usually under the back of the bar or in a walk-in cooler near the kitchen. In some restaurants or bars, the beer can be coming from as far as 50 feet away! Without proper beer line cleaning and maintenance, draft beer can become tainted and contaminated.
This is bad for the bar / restaurant owner and the beer lover alike!! Knowing the importance of cleaning beer lines is an invaluable lesson for any restaurant or bar owner.
How do beer lines become dirty?
Yeast – Beer contains yeast. When lines are not properly cleaned, yeast builds up and can clog the lines as well as effect the taste of the beer being served. Yeast build up may result from a small amount left from the brewing process. It can be recognized by its white or grey color and is usually found on the surfaces of the beer system that are exposed to air: faucets, keg couplers and drains for example.
Mold – We all know that mold can be hazardous to your health. Mold also has an effect on beer. When the beer system is exposed to the air there is a risk of mold growing. It can be recognized by its brown or black color and is found on surfaces that are exposed to air: faucets, keg couplers and drains.
Beer Stone – Beer stones are Calcium Oxalate deposits that are created during the brewing process and is a result of combining calcium and oxalic acids or salts at cold temperatures. Beer stones will build up and eventually flake off on the inside of the beer lines if not properly cleaned. They have a negative effect on the taste and quality of beer.
Bacteria – Bacteria found in beer is in small enough amounts that they typically do not present a hazard to human health. However, a bacteria build up can be potentially harmful. In addition, if lines are not cleaned properly the bacteria will negatively effect the taste and quality of the beer.
