Which CO2 bottle is the right one for the dispensing system?
Not every CO₂ bottle for a tap system is suitable for every use. If you want to occasionally tap a fresh beer at home, a compact 0.5 kg CO₂ bottle is ideal. This is lightweight, portable, and perfectly suitable for smaller quantities—perfect for 5-liter tap systems or mobile party systems.
For regular use or larger events, however, a more powerful solution is recommended: A 10 kg CO₂ cylinder offers excellent value for money for frequent users. Also in high demand is the handy 2 kg CO₂ cylinder, which represents a good compromise between mobility and capacity. It can be easily transported and connected to almost any standard CO₂ cylinder dispenser.
When purchasing, make sure that the CO₂ bottle for your beer dispensing system has the correct connection and complies with applicable safety standards. Many users consciously choose to purchase a certified CO₂ bottle for their dispensing system to avoid the need for subsequent upgrades or replacements.
Connecting a CO2 bottle dispenser – this is how it's done safely and quickly
Connecting a CO₂ cylinder to your dispensing system can be done in just a few steps – provided you know what to look for. First, you should check the cylinder's current pressure. A new CO₂ cylinder for your dispensing system typically has a pressure of around 50 to 60 bar. Make sure the valve is closed before connecting.
The CO₂ bottle is then connected to the beer hose system using a pressure reducer. Ensure that all threads are clean, tight, and properly tightened. Modern systems now make connection particularly straightforward – even without prior technical knowledge. Many manufacturers supply their systems with quick connectors or practical assembly aids.
Whether you're using a 5-liter dispensing system with a CO₂ bottle, a 2 kg bottle, or a 10 kg bottle, the connection process is virtually identical. It's important that you set the correct working pressure after connecting. This can vary depending on the beer type and ambient temperature. Once everything is connected correctly, nothing stands in the way of enjoying fresh beer.
What is the ideal pressure for the CO2 bottle on the dispenser?
The correct pressure setting is crucial for a nice head and a consistent pour. Too much pressure causes the beer to foam over, while too little pressure leads to a flat taste. But what is the optimal pressure for the CO₂ bottle on the tap?
The recommended working pressure is generally between 0.8 and 1.2 bar, depending on the beer type, the length of the line, and the temperature. Light beers usually require less pressure than wheat beers. Longer hose systems or cooler environments may require a slight increase in pressure.
A common mistake is the combination of an unsuitable pressure regulator and bottle size. Make sure your system is compatible with your chosen CO₂ bottle for the dispensing system – regardless of whether you use a 0.5 kg, 2 kg, or 10 kg bottle. The pressure should also be checked again after replacing the CO₂ bottle.
Our tip: Use a pressure gauge to keep an eye on the CO₂ bottle pressure at all times. This ensures consistent quality when dispensing beer – and avoids unpleasant surprises when serving.
How many liters of beer can you tap with a 2kg CO2 bottle?
One of the most frequently asked questions is: How long will a 2 kg CO₂ bottle last on the tap system? The answer depends on several factors – such as the set pressure, the ambient temperature, the hose length, and, of course, the amount of beer being tapped.
As a guideline, a 2 kg CO₂ bottle can dispense approximately 400 to 500 liters of beer. This is usually enough for several weeks, even with regular use. This size is particularly popular with home brewers—as well as in the commercial sector as a backup bottle. Those who dispense even more frequently will benefit from a 10 kg CO₂ bottle, as refilling is required much less frequently.
By the way: With a compact 5-liter dispenser with a CO₂ bottle, the contents last even longer, as the consumption per dispensing is very low. Our tip: Monitor the consumption after filling the CO₂ bottle and plan for refills well in advance.
Even better: Always keep a spare bottle on hand. This way, you can avoid downtime—especially at events or in restaurants. Alternatively, we recommend using a second CO₂ bottle for the dispensing system, which you can use alternately.
