No matter which method of dispense is used, remember to keep the keg chilled to 38° for both dispensing and storage.
There are a wide variety of methods available for dispensing draft beer at a party.
Keg Party Pumps are the most commonly used method to dispense draft beer at parties.
Pressure to dispense the beer is provided by a hand operated pump which is used to pump air into the keg.
Party pumps are generally used in single keg special events environments, with the beer being consumed within a few hours, because the outside air pumped into the keg will cause a bacteria reaction that will spoil the beer within 8-12 hours.
Party Dispensing System that use CO
2 are the ultimate way to dispense draft beer at a party. The pressure is provided by a CO
2 tank so there is no need to pump the keg as with a traditional party pump. Just open the faucet and let the beer flow.
Using CO
2 will maintain the freshness of draft beer longer than party pumps which add unfiltered air to the keg. If the draft beer is kept at the proper temperature and pressure, this type of dispensing will allow the beer to remain fresh for 45-120 days.
