2) Contaminated Air Line,
and/or defective Thomas or
Tongue Vents
•
Air hoses, air lines and vents, should be examined,
and if contaminated, replaced.
•
Dirty air lines should be washed with a good
cleaning compound, normally used for cleaning
coils, and then rinsed clean.
3) Rubber hose absorbing and
retaining odors
•
Rubber hose will absorb and retain odors. An
approved Vinyl tubing is best for air since it does
not absorb moisture, and is not affected by oily
substances. Replace hose with Vinyl or Braided
Vinyl (High Pressure) air line tubing.
•
A fresh, outdoor, air line is imperative when air is
the source of pressure.
4) Unfiltered or contaminated
air
•
Air must always be filtered.
•
See Flat Beer, Correction for moisture-ridden air
5) Improper transportation or
storage
•
Change beer storage to refrigerated storage and
transportation.
Barrels should remain refrigerated or iced. Sour
beer is generated as a result of secondary
fermentation, above 45 degrees. High
temperatures may cause the start of secondary
fermentation in the barrel.
Problem: Wild Beer
When poured beer is all foam or has too much foam and not enough liquid beer.
Causes
Corrections
1) Improper drawing 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.
2) Yeast build up in faucet
•
Clean faucet spout with a good brush daily. Scour
all internal faucet parts regularly.
•
Replace worn washers as required. If faucet does
not open wide, worn parts or entire faucet must
be replaced.
3) Kinks, dents, twists or
obstructions in coils or lines
•
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 beer line
•
Keep all metal beer lines straight from barrel to
faucet; never permit lines to sag, as this creates
traps that may cause wild beer.
