FAQ

What is the co2 gas cylinder used for?

The co2 gas in the cylinder is used to propell the beer from the keg through the tap. 

The CO2 gas in the keg sits above the liquid in the keg and has 2 functions:

  1. It is used to propel the beer from the keg, through the tap into the glass.
  2. It is used to retain the carbonation in the beer in the keg so the beer is always carbonated. It should not lose its carbonation like the 2litre bottle of carbonated drink left in your fridge once its been opened.

If my beer in the keg loses carbonation what must I do?

Increase the pressure in the keg to 3 Bar and leave it. If cold the beer will recarbonate in 24 hrs. You can then continue to dispense fresh carbonated beer.

Air is not a friend to beer as it allows the bacteria to continue to grow.

Pre carbonated liquids retain their carbonation much longer if they are refrigerated.

How many kegs will a 2KG CO2 cylinder do? As a rule of thumb a 2kg CO2 cylinder will do 12x 20L Kegs of beer.

  1. Attach the tap to the OUT connector on the keg. Don’t force the connector as although the OUT and IN look the same they are slightly different.
  2. Screw the 16gram gas cylinder into the connector. The gas will start releasing when the seal is broken so screw it in fast until firm.
  3. Attach the CO2 connector to the IN connector on the keg.
  4. Your growler when filled at the store will have a CO2 head in the keg of approximately 2 Bar. This will keep the beer nicely carbonated. If you dispense the beer at this pressure it will foam a lot. To avoid this when you want to dispense the beer release the pressure from the keg using the quick release value. Do not open the keg as this will allow air to make contact with the beer and potential contamination.
  5. Start to tap the beer when ready. The beer should begin to flow from the tap at a reasonable rate. Should you want to increase the flow pump the gas connector a few times and check the flow. Do this until you are happy with the flow. (Repeat as required)
  6. When the party is over and there is still beer in the keg why don’t you finish it! If you want to keep the beer in the keg empty the balance of the 16g gas cylinder into the keg. This will ensure the beer remains carbonated. (this isn’t an exact science so rather more gas than less.) A good option for carbonating the keg is our standard Real Beer Company 2kg CO2 cylinder which is available as an optional extra.
  7. For the beer to remain fresh the keg must be refrigerated.
  8. Remove the tap from the keg and wash well in hot water. Using the RBC chlorine tab diluted in 5 litres of water is recommended.
  9. When the keg is empty open the seal and wash the keg on the inside thoroughly using the RBC chlorine tab diluted in 5 litres of water. Once completed rinse the keg in fresh water.

  1. Before filling ensure the keg is thoroughly cleaned.
  2. Pour the beer into the keg. Close the keg and ensure the seal is sitting proberly. Refrigerate the keg.
  3. Increase the pressure in the keg to 3 Bar and leave it. If cold the beer will be carbonated in 24 hrs. A good option for carbonating the keg is our standard Real Beer Company 2kg CO2 cylinder which is available as an optional extra. You are now ready to serve fresh beer and continue as per Corny 9L Growler (Store filled)

Corny 9L Growler (Home filled pre-carbonated liquid such as G&T, Brandy & Coke etc) 

  1. Before filling ensure the keg is thoroughly cleaned.
  2. Pour the liquid into the keg. Close the keg and ensure the seal is sitting properly. Refrigerate the keg.
  3. If the keg isn’t to be used immediately increase the pressure in the keg to 2 Bar and refrigerate if possible. A good option for carbonating the keg is our standard Real Beer Company 2kg CO2 cylinder which is available as an optional extra.
  4. You are now ready to serve fresh pre carbonated drinks from your keg and continue as per Corny 9L Growler (Store filled).
