3

LIKELY CAUSES — RANKED MOST COMMON FIRST

  1. 1

    CHILL HAZE FROM COLD

    Beer stored below 30°F precipitates protein-tannin complexes.

    Fix
    • Hold kegs at 36–38°F; never freeze.
  2. 2

    YEAST / SEDIMENT DISTURBED

    Keg rolled or jostled before tapping.

    Fix
    • Let kegs settle upright for 24 hrs after delivery.
  3. 3

    BACTERIAL CONTAMINATION

    Pediococcus or Lacto in dirty lines produces persistent haze and ropey strands.

    Fix
    • Tear-down clean affected lines with acid + caustic; consider line replacement.

STILL NOT FIXED?

Capture temp at the faucet, applied PSI at the regulator, and a photo of the pour. Then check the spec reference or run a full line cleaning.
