The Importance Of Maintaining Draft Beer Pressure
by Kanyon Walker
Proper draft beer storage, taste and presentation relies on maintaining constant pressure.
To prevent loss of carbonation of the beer, a constant pressure must be maintained in the barrel. Twelve to fourteen pounds of pressure of carbon dioxide gas is best for protecting carbonation and maintaining the original brewery fresh taste.
When the beer in the barrel is at 38 degrees, it has an internal pressure of 12 to 14 pounds per square inch. When 12 to 14 pounds of gauge pressure is applied to the barrel that is enough to keep all the natural carbonation in the beer and force it through the lines "brewery fresh".
When your gauge pressure is set too low at less than the natural pressure, the natural carbonation level will diminish as the keg is dispensed and the beer in the barrel will go flat. If the gauge pressure is above the natural pressure in the beer, the beer will absorb too much carbonation and take on an unnatural taste.
The regulator is key to controling the compressed gas system. Carbon dioxide gas pressure is approximately 875 lbs. per square inch at 70 degrees. The regulator must reduce this pressure by regulating the flow of gas from the compressor to the keg.
You must watch the pressure regulator because turning the adjusting key of the regulator with the shut off valve closed will set the pressure anywhere from 0 to 60 pounds.
If the regulator is sluggish and the needle tends to fall downward, this permits a drop in pressure when beer is drawn. This allows for flat beer at the end of the barrel. An overactive regulator, where the needle creeps upward, allows for increasing pressure as beer is drawn creating over carbonated beer. If you notice the regulator acting either sluggish or creeping higher, return it to the manufacturer for repair.
Be sure your regulator is equipped with a pressure relief device. This will prevent any incidental pressure build up which could cause the barrel to burst, resulting in injury.
Pressure release tapping devices and vents that release excessive pressure at the barrel should be a part of every draught beer system.
