I was racking from fermenter to Secondary, and noticed a film on the top. There was also a real yeasty smell. The OG was 1.053, which was right on, and its at 1.012 which is about where Its supposed to be. My question is, could an infection cause the film and weird smell, or could it be from pitching to much yeast? And if so will it clear in the secondary? Beer is very cloudy.
