DRAUGHT BEER TROUBLE GUIDE

CLOUDY BEER

When beer in glass appears hazy, and not clear.

Causes Corrections

FLAT BEER

Foamy head disappears quickly: beer lacks usual zestful brewery fresh flavor.

Causes Corrections

• Greasy glass

• Do not wash beer glasses together with glasses

that have contained milk or any other fatty

substance. Lipstick is a fatty substance.. Make

sure it is removed from glass.

• Excess amount of germicides build up and leave

a fatty film on glass, which may cause flat beer.

• It is preferable to steam and sterilize glasses

where health laws permit.

• Wash glasses thoroughly with a good detergent.

• Do not use soap.

• Do not dry-wipe glasses. Permit glasses to air-

dry by placing them on wire or corrugated metal.

• Rinse in fresh cold water just before serving

beer. It is best to serve beer in a wet glass.

• Improper drawing of beer into glass.

• Open faucet quickly and completely.

• Check and find the correct distance to hold

glass from faucet when drawing. Proper foam

should be a tight creamy head, and the collar on

the average glass should be ¾” to 1” high.

• Beer drawn without head has appearance of

being flat.

• Over chilling beverage cooler and/or

beverage lines.

• 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.

• Contaminated air source. If possible

change to CO2 gas as a pressure

source.

• Defective Thomas or tongue vents.

• 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.

• General conditions causing cloudy

beer.

• See wild beer corrections #2, #5, #6, and #7, and

flat beer corrections #5, #7, and #8.
