Cause 5
Excessive amounts of CO
2
.
Correction
• Adjust the CO
2
pressure to as low as possible. However, the applied pressure
must remain slightly higher than the internal pressure of the beer. No more
than 18 lbs. should be applied. The proper amount should be between 6 - 9
psi/lbs.
• The colder the beer and the higher the applied CO
2
pressure, the more rapid
the absorption of CO
2
by the beer. This over-carbonates the beer, causing Wild
Beer.
• Check the pressure regulators periodically to ensure that the operating
pressures remain constant.
Cause 6
Not enough pressure or no pressure at all.
Correction
• Check for defective air vents.
• Always turn the pressure on before drawing beer.
Cause 7
An old keg of beer which has not been stored in cool temperatures has been
used.
Correction
• If beer has been allowed to stand in warm temperatures beyond 45°F for an
excessive length of time, it may begin a secondary fermentation. Store beer at
40°F or below all year round.
Beer Condition: Tail-End Beer
Beer draws well at the beginning of the keg. Towards the bottom, it becomes
flat. This is more likely to occur when beer turnover is slow.
Cause 1
Where air is used as a pressure source, air replaces the CO
2
in beer, causing flat
beer. This problem is not evident when beer is being drawn rapidly.
Correction
• Whenever possible, use CO
2
Gas as a pressure source.
