A had an extract cream ale iwith a dry yeast in the primary for about 22 days before transferring to secondary. A week later a whitish film has appeared on top. Is this a spoiled batch? It's been pretty hot here and I'm wondering if it's shot. Was very careful with keeping things sanitary.
I just came up with the same problem. I racked and bottled while leaving the film in the carboy. Did you taste it? Mine tasted strongly like alcohol, maybe due to the high fermenting temperatures???

White Film on the Surface
Problem: Caused by an airborne mold. Appears as a dusty white (very thin) film in the fermenter, and then appears again in the bottles beer. White film mold is not usually accompanied with a taste defect, so it is ok to drink the beer.
Size emphasis my own.
