Troubleshoot Common Draft Beer Problems

Problems serving a perfect beer? We’re here to help!

Condition Causes Corrections
Cloudy Beer
Beer appears hazy and not clear.
Over chilling Keep refrigerator temperature between 36º to 40ºF.
Partial opening of beer faucet Always open faucet quickly and completely.
Having anything warm on or near your keg When anything that is not cold is placed on or near a cold keg, the beer may absorb warmth too.  So, be careful what you store in your kegerator!
Flat Beer
Foamy head disappears quickly.  Beer lacks usual zestful brewery-fresh flavor.

Or

Loose Foam
Large soap-like bubbles.  Foam settles quickly.

Greasy Glasses Wash glasses thoroughly with a good detergent; do not use soap.  Allow glasses to air dry.  Rinse in cold water just before serving beer.  Use beer glasses for beer only.
Improper pour Open the faucet quickly and completely, and practice for perfect foam.  Proper foam should be a tight creamy head, and should be ½” to 1″ high.
Not enough pressure Check CO2 tank - make sure it is on and not empty.

You should be able to fill a 10 oz glass in 4 seconds.  If beer runs slowly, increase pressure.

Make sure that there are no obstructions in the airline.

Check and, if needed, replace the airline or CO2 regulator and gauge.  Regulators will wear down, so be sure to replace after 4 - 6 years.

Foamy or "Wild" Beer
Too much foam, not enough liquid.
Warm beer Always keep your keg between 36º to 40ºF.
Excessive CO2 Lower the amount of CO2 going to the keg by adjusting the regulator.  Typically, you should keep your regulator set between 10 and 12 PSI.  If a keg is over pressurized, pull the relief valve on your keg coupler for a few seconds to release CO2.  Wait about 15 minutes, then turn your CO2 tank back on.  If your regulator is older and is not operating corectly, you may need to replace it.
Old beer lines Replace old beer lines.  If you bought or inherited an older system, it would be wise to replace the beer line.
Obstruction in faucet The faucet should be removed, disassembled and cleaned with hot water and a brush every few weeks.
Worn faucet parts Replace worn washers.  If faucet does not open wide, worn parts or entire faucet must be replaced.
Warm spots in your beer line All beer tubing should be kept inside your fridge.  Long beer line runs (more than 6 feet) can cause your CO2 pressure to be out of whack.  A larger inside diameter of beer tubing may be necessary.
