
1
Over chilling beverage
cooler and/or beverage
lines.


Cracking, or when
partially opening beer
faucet.

3
Contaminated air
source. If possible
change to CO2 gas as a

General conditions
causing cloudy beer.

5
Unrefrigerated food
placed on barrel on cold
beer.
Causes
1 
Large soap-like bubbles
(sometimes called fish
eyes). Foam settles
quickly.
Beer draws well at the beginning of the barrel. Towards the end of the barrel the beer is flat.
This is more likely to occur when beer turnover is slow.
Causes

1
Where air is used as a
pressure source, air
replaced the CO

beer causing flat beer.
Where beer is being
drawn rapidly this
problem is not so
evident.

DRAUGHT BEER TROUBLE GUIDE

CLOUDY BEER
Corrections

Excessive low temperatures may cause hazy, cloudy beer,
particularly when beer lies in cold coil for long periods of time.
Make certain that lines are thoroughly cleaned, and then raise
temperature slightly.

Open faucet quickly and completely.

Replace worn washers and parts in faucet when necessary to
permit full opening of faucet.

See flat beer, correction #7

Always draw fresh air from an outside source to compressor.
Attach hair felt filter to the outside intake, in addition to filter in
line.

Bacteria growth may result from beer backing up through
defective vents in air line, air pressure will then carry this into
beer barrel.

Check and replace defective vents frequently, and thoroughly
clean air line.

See wild beer corrections #2, #5, #6, and #7, and flat beer
corrections #5, #7, and #8.

When unrefrigerated products, such as meats vegetables, fish,
or fruits, are placed on barrel of cold beer, the beer becomes
warm long before these products chill down to the cold
temperature. This change in temperature will cause Cloudy
Beer.
