Draft Troubleshooting
Problem
Cause
Correction
Beer is cloudy: The
beer in the
glass
appears hazy and
not clear.
Excessively low
temperatures
may
cause hazy
or
cloudy beer,
particularly when
the beer lies in
the
cold coil for
long
periods of
time.
Drain a few ounces before drinking.
Raise the temperature setting of the unit.
Glasses may not
have been
cleaned
properly.
Do not wash beer glasses together with glasses that
have
contained milk or any other fatty substance. An
excessive
amount of germicide build-up may also
leave a fatty film,
which will cause beer to go flat.
It is preferable to steam and sterilize glasses where
health laws permit.
Wash glasses thoroughly with a good detergent to
remove all fatty substances (e.g., lipstick).
Do not use soap.
Do not wipe the glasses dry. Permit glasses to air-dry
by
placing them on a wire rack or corrugated metal
sheet.
Rinse the glasses 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 the faucet quickly and completely; proper foam
should be a tight creamy head. The collar on the
average
glass should be ¾" to 1" high. Beer drawn
without a head
has the appearance of being flat.
Not enough
pressure
Increase the pressure if beer runs too slowly. The
correct
flow should fill a 10-oz glass in 4 seconds
(approx. 8 oz of
liquid). Check the pressure source to
determine whether
there are obstructions in the air
line. Replace a sluggish air
source or the CO
2
regulator and gauge. The tank pressure
must always
be higher than the pressure used on the keg.
Always
apply pressure to the keg before drawing beer.
Beer has off taste:
Often bitter and
bite-y; sometimes
completely
lacking
flavor and zest. It
may also
have an
oily or foul odor
which may
carry an
unpleasant taste.
Improper
cleaning of the
tap
Brush and clean the tap properly. It should be
scoured using a detergent, then rinsed clean.
Contaminated air
line
Beer tube should be examined. If contaminated, it
should be replaced.
