I have noticed I have two kegs (rye IPA and English mild) that have suddenly gone cloudy despite being brilliantly clear earlier.  The mild especially was very clear.  Both kegs are probably 75% empty.  They Taste about the same currently as they did before, the IPA perhaps a little fuller.  Both hold a nice head still.  They have not been moved out of the keezer since initial placement there.  The rye IPA was fined with gelatin, the mild was naturally clear with a high floc yeast.  Any ideas what could be going on?

I would guess contaminated. How long on tap? How long since limes cleaned?

I try to clean the lines between kegs.  The IPA is 2 months out since brew Day, the mild prob 3 months.  Would you not expect some flavor changes with infection?

I had a lager last year do that. At first I thought it was a an infection, but the more likely culprit was  oxidation. I’m not sure what happened, but I’ve never had that problem since. BTW they got darker too.

Usually yes, and maybe it's yet to come
