Maintaining a constant pressure for beer is essential for proper storage, taste and presentation.
A constant and uniform pressure should be maintained in the barrel while beer is on tap to prevent loss of carbonation in the beer. A pressure of twelve to fourteen pounds of C02 gas is usually most satisfactory to protect the carbonation and original brewery-fresh taste of the beer.
To keep beer pressure maintained at 12 to 14 pounds per square inch, it's temperature must be kept at 38 degrees. This will keep it brewery fresh with carbonation.
When the pressure gauge is set too low, carbonation will seep out of the beer and into empty keg space. This creates flat beer. If the gauge is set to high, as the keg diminshes, beer will have too much carbonation and have an unnatural taste.
The regulator of a compressed gas system determines pressure and carbonation as beer is stored and consumed out of the tap. The pressure of CO2 gas in the keg is around 875 lbs. per square inch at 70 degrees. The regulator must control the reduction of pressure by controlling the flow of gas from the cylinder to the keg.
With the shut-off valve closed, turning the adjusting key of the regulator clockwise will set it at any pressure from 0 to 60 pounds. Watch the pressure regulator.
Only an accurate regulator will maintain uniform pressure. Be sure the needle on the gauge holds a constant position. A sluggish regulator (needle falls downward) permits a drop in pressure when beer is drawn, resulting in flat beer toward the end of the barrel. A creeping regulator (needle creeps upward) permits pressure to increase during idle periods, resulting in wild, over carbonated beer. Creeping is caused by a leaky, defective seat inside the regulator. For your own protection, return sluggish and creeping regulators to the manufacturer for repair or replacement.
Keep your pressure system safe. When installing or replacing your C02 gas pressure regulator or air pump, be sure it is equipped with a pressure-relief device, preferably a release valve. Excessive pressures can develop from carelessness or pressure regulators that are not operating properly, which could result in the barrel bursting and causing serious injury or damage.
Every draft beer system should include a pressure relief valve.
