Beer Condition: Sour Beer
Beer tastes and smells extremely yeasty or moldy.
Cause 1
Improper transporting of beer kegs. Beer that is delivered on an open truck
during high summer temperatures may start a secondary fermentation process.
Correction
• If possible, have beer kegs delivered in a closed, refrigerated truck. If an open
truck is used, cover beer kegs with tarpaulin for protection against summer heat
and warm air.
Beer Condition: Wild Beer
Beer that is either all foam, or too much foam and not enough liquid.
Cause 1
Improper drawing of beer into the glass.
Correction
• Open the faucet quickly and completely.
• Proper foam should be a tight, creamy head, and the collar on the average
glass should be 3/4" to 1" high.
Cause 2
Yeast growth or other obstructions in the faucet, which is usually caused by
a non-refrigerated faucet. Worn faucet parts and worn faucet washers.
Correction
• Check for, and replace any kinked, dented, or twisted lines from the barrel to
the faucet.
• Examine for frayed coupling washers behind the faucet that may cause an
obstruction.
Cause 3
The beer was stored in an area that is not cold enough and has thus
become warm.
Correction
• Keep kegs of beer refrigerated at all times at 40°F or below all year round!
Cause 4
Too much pressure.
Correction
• First, check the source of pressure to make sure it is working. Then adjust the
pressure to suit a properly balanced system. The correct beer flow should fill a
10oz. glass in 5 seconds at the proper temperature.
