WILD BEER
Beer, when drawn, is all foam, or too much foam, and not enough liquid beer.
Cause Corrections
1)
•
Improper drawing beer into glass.
1)
•
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.
2)
•
Yeast growth, or other obstructions in
faucet.
•
Worn faucet parts and worn faucet
washers.
2)
•
Clean faucet spout with a good brush daily. Scour
all internal faucet parts at least once a week.
•
Replace worn washers as required. If faucet does
not open wide, worn parts or entire faucet must be
replaced.
3)
•
Kinks, dents, or twists in coils, or direct
draw lines: obstructions in line, near, or
behind faucet.
3)
•
Check for, and replace kinked, dented, or twisted
line from barrel to faucet.
•
Examine for frayed coupling washer behind faucet
that may cause obstruction.
4)
•
Sag, or trap in line.
4)
•
Keep all metal beer lines straight from barrel to
faucet; never permit lines to sag, as this creates
traps that may cause wild beer.
5)
•
Beer too warm at faucet;
•
Beer too warm in Coil System.
•
Beer too warm in Air Shaft System.
5)
•
Temperature at faucet must always be at least 2
degrees colder than at barrel.
•
In sweet-water refrigerated, or ice-water system,
faucet shank must always be submerged.
•
In Cold Air System, the coldest air from the blower
must first be directed to the faucet, and then
circulated back to pre-cooler.
6)
•
Hot spots in line.
6)
•
Insulate all beer lines; a long beer run must be
constantly refrigerated. Insulation helps. But
insulation is not refrigeration.
•
Keep all beer lines away from hot water pipes, hot
air ducts, and steam lines. A cold steam pipe in
the summer is a hot steam pipe in the winter.
7)
•
Pre-Cooler, or Direct Draw Dispenser,
too warm.
7)
•
It is always summer indoors and in the basement,
therefore, maintain pre-cooler, and direct draw
dispenser temperature at 40° all year round. If
direct draw temperature cannot be lowered,
increase applied pressure; however, balance the
system by changing to smaller diameter length of
vinyl tubing or install a foam control faucet.
•
Never shut off refrigeration – day or night.
8)
•
No cold storage space for delivered
beer; beer becomes warm in barrel.
8)
•
Coil systems, and direct draw systems, must be
properly balanced in order to apply pressure
required for warmest temperature to which barrels
of beer will be exposed. A control beer faucet can
be used in place of a restricted coil to balance
system.
