Identify the Problem
If you are running a pub or restaurant, then you already know how important it is to have a good quality beer tap system. Not only does it improve the taste of the beer, but it also enhances the overall experience of the customer. However, if you have been noticing that your beer taps have been producing foamy beer, then it is high time that you fix this issue. Foamy beer can be a major turn off for customers as it affects the taste and reduces the quantity of beer that they are being served. In this article, we will guide you through the process of fixing foamy beer taps, starting with identifying the problem.
The foaming of beer can be due to various reasons such as incorrect temperature, wrong pressure, dirty dispense lines, and many more. One of the main reasons why you may be experiencing foamy beer is due to the presence of air in the system. This air can get trapped in the beer lines, and when the beer is dispensed, it mixes with the beer, resulting in foaming. The presence of air can be due to various reasons such as poor maintenance, improper installation, or even due to human error.
Another reason why you might have foamy beer is due to incorrect temperature. If the beer is not being stored at the right temperature, then the carbon dioxide in the beer can separate from the liquid, resulting in foaming. Additionally, if the temperature is too low, then the carbonation might be too high, leading to foaming as well. Therefore it is highly recommended to store the kegs at the appropriate temperature to maintain the right level of carbonation in the beer.
Moreover, incorrect pressure can also lead to foamy beer in the taps. If the pressure is too high, then too much carbon dioxide will be applied, resulting in over-carbonation and foaming. On the other hand, if the pressure is too low, then there might not be enough carbonation, leading to flat beer. It is essential to ensure that the pressure in the system is set according to the recommended manufacturer’s instructions.
The quality of the dispense lines also plays a significant role in the production of foamy beer. The lines should be clean and free from any contaminants that might affect the taste and quality of the beer. If the lines are dirty or clogged, then the beer will not pour out smoothly, leading to foaming. Therefore, it is vital to clean the lines on a regular basis and replace them if necessary.
In conclusion, identifying the problem behind the foamy beer is the first step in fixing the issue. If you are facing issues with your beer taps, then you should start by checking the temperature, pressure, and the quality of the dispense lines. By addressing these issues, you can ensure that your customers are served with high-quality beer that is not only tasty but also refreshing.
Clean the Beer Lines
Keeping your beer lines clean is crucial to ensure that the beer you serve is of high quality and does not become foamy. Over time, the lines can become contaminated with bacteria, yeast, and mold, leading to off-flavors and excess foam in the beer. Here are some steps to clean your beer lines:

Gather your Supplies
You will need a cleaning kit, which can be purchased from your beer supplier or online. The kit typically includes cleaning solution, a hand pump, and faucet brush. You will also need a bucket, towels, and safety glasses.
Shut off Your System
You should always shut off the beer supply to the affected lines before cleaning them. This can be done by turning off the tap or shutoff valve near the keg. This will prevent beer and cleaning solution from spilling or damaging the system.
Remove the Faucet
The faucet is the last part of the beer line before it dispenses beer. It can become clogged with sediment, leading to a buildup of pressure and foamy beer. To remove the faucet, unscrew it from the shank using a wrench or pliers, and then disassemble it. You can soak the components in a cleaning solution or use a faucet brush to scrub them. Rinse the parts with water and dry them with a towel.
Flush the Lines
To clean the beer lines, fill a bucket with water and add the cleaning solution according to the instructions. Use the hand pump to push the solution through the lines, starting from the faucet end. This will remove any sediment, bacteria, or yeast that has accumulated in the lines. Keep pumping the solution until it comes out clear and free of foam. Rinse the lines with water to remove any remaining cleaning solution.
Reconnect the Faucet
Once you have finished cleaning and rinsing the lines, it’s time to reattach the faucet. Make sure that it is tight and secure, and that the gasket is in place. Turn on the beer supply to the lines and let the system run for a few minutes to flush out any air and verify that the beer is flowing smoothly.
Repeat the Process Regularly
It’s important to clean your beer lines regularly to ensure that they remain free of contamination and do not become clogged. The frequency of cleaning depends on how often the lines are used and how quickly the beer is consumed. A general guideline is to clean the lines every two weeks or once a month. However, if you notice any issues with the beer quality or excessive foam, it may be necessary to clean the lines more frequently.
By following these steps, you can ensure that your beer lines are clean and free of contaminants, which will result in a better-tasting beer with less foam. Cheers!
Adjust the CO2 Pressure
One of the most common causes of foamy beer taps is incorrect CO2 pressure. An insufficient amount of carbon dioxide can result in flat beer, while an excess of CO2 can cause foam. Therefore, it is essential to adjust the CO2 pressure to achieve the perfect balance.
The first step in adjusting CO2 pressure is to determine the right pressure required to dispense beer correctly. The CO2 pressure required for dispensing beer varies depending on several factors. These factors include temperature, elevation, and the type of beer being served. A general rule of thumb is that for every two-degree increase in beer temperature, the CO2 pressure should increase by 1 PSI.
To determine the correct CO2 pressure, follow these steps:
- Ensure that the beer temperature is at the recommended serving temperature. The ideal temperature for most beer types is between 35 and 40 degrees Fahrenheit.
- Ensure that the CO2 tank is at the recommended pressure level. The recommended CO2 pressure for dispensing beer is typically between 12 and 14 PSI.
- Using a beer pressure gauge, measure the pressure in the keg. Ensure that the pressure is not more than 3-4 PSI above the required pressure level.
- If the pressure is too high, release some gas from the keg manually. Wait for a few minutes and measure the pressure again. Repeat this process until the desired pressure is achieved.
- If the pressure is too low, increase the CO2 tank’s pressure until the desired pressure is achieved.
It is important to note that when adjusting the CO2 pressure, it is best to make small changes and wait for a few minutes to observe any changes. Additionally, keeping the beer lines clean is essential in maintaining the right CO2 pressure. Dirty lines can result in clogs that could cause the beer to foam excessively.
Adjusting the CO2 pressure is a simple and effective way of eliminating foamy beer taps. With the right pressure level, the beer will be dispensed smoothly and at the right temperature, ensuring that you get the perfect pint every time.
Properly Store and Serve Beer
One of the most important things to remember when it comes to fixing foamy beer taps is to properly store and serve beer. Here are some tips on how to do just that:
1. Store beer at the right temperature
Beer should always be stored at the right temperature to maintain its quality and flavor. For example, lagers should be stored between 45-55 degrees Fahrenheit, while stouts should be stored between 50-55 degrees Fahrenheit. Make sure your beer is stored in a cool, dry place away from direct sunlight and heat sources. The longer a beer sits in storage, the more chance there is of it losing its flavor and going stale. On the other hand, storing beer at too low of a temperature can cause it to freeze, expand, and ultimately result in a massive mess when you open it.
2. Clean your beer lines regularly
Another important step in properly serving beer is cleaning the lines that the beer travels through before it reaches the tap. Over time, beer lines can become contaminated with yeast, bacteria, and other impurities that will ruin your beer’s flavor and aroma. Cleaning beer lines regularly will prevent these impurities from building up and keep your tap system running smoothly.
3. Balance your pressure and volume
It’s crucial to balance the pressure and volume of your beer system to avoid foamy beer. Pressure is essential to ensure that the beer moves from the keg to the tap properly, while volume determines how much beer flows into a glass with each pour. When these two factors are not balanced, the result is typically an excessive amount of foam in your beer. It’s recommended that you consult with a professional to help you calibrate your draft system accurately.
4. Use the proper glassware
Using the proper glassware is often overlooked when it comes to serving beer, but the reality is that it makes a big difference in the quality of your beer experience. The shape and size of the glassware you use can affect the temperature, aroma, and flavor of your beer. For example, pint glasses are perfect for enjoying hoppy beers, while tulip glasses are ideal for savoring Belgian-style beers. Serving your beer in the right type of glassware will enhance the overall experience and reduce the risk of having foam overflow.
In conclusion, storing and serving beer properly is the key to fixing foamy beer taps. Make sure to follow these tips and keep your system running correctly. By doing this, you will avoid the disappointment of a badly poured beer and enjoy the flavor, texture, and aroma of your brew.
Regular Maintenance and Upkeep
Having a foamy beer tap can be frustrating, but it can easily be avoided with regular maintenance and upkeep. Here are some tips that can help you maintain your beer tap.
1. Clean the Lines and Taps Regularly
Dirt and bacteria can build up in the beer lines and tap, leading to foam. To avoid this, clean the lines and tap regularly. You can do this by running hot water through the lines, followed by a cleaning solution. Rinse thoroughly with water before reattaching them to the tap.
2. Check the Temperature
The ideal temperature for beer is between 38 and 44 degrees F. If the beer is too warm, it will expand and create foam. Make sure that the temperature of the beer in the keg matches the temperature on the tap. If they are not the same, adjust the temperature on the tap accordingly.
3. Adjust the Pressure
Beer kegs need to be pressurized appropriately, or the beer will come out foamy. If your beer is foaming, adjust the pressure on the tap. Start with a low pressure and gradually increase it until the beer comes out smoothly. If this doesn’t work, you may have to check the keg pressure as well.
4. Store Beer Kegs Properly
How you store your beer kegs can greatly affect the quality of the beer. Kegs should be stored upright and kept at the right temperature till they are tapped. You should also ensure that the kegs are not exposed to sunlight or heat as this can cause the beer to go bad or become foamy.
5. Use Quality Beer Glasses
The type of glass you use can also affect the foaminess of the beer. Use quality beer glasses that are clean and dry. Wet or dirty glasses can cause the beer to foam. Make sure that the glasses are at room temperature and not chilled as this can also cause foaminess. Rinse your glasses with cold water before use and dry them with a clean towel. Avoid using detergent or soap that can inhibit the head of the beer.
Following these steps should help you maintain a healthy beer tap and avoid foamy beer.
