that could be a pellicle, or not.It's hard to tell with the brown glass. From what I can tell, it looks white and it's floating on top. When I disturb it, sediment (looks like yeast particles) falls down.
Here's a better picture.
Have you poured some beer form the bottle pictured? If not that is too much head space.
Pour one of the beers in a sanitized pilsner glass. Cover with sanitized foil and let it sit away from strong light for a few days. If it is infected a strong pellicle will form across the surface.
How do you fill your bottles? A bottling wand will leave the appropriate head space in bottles of any volume.No, it's a bomber, so it has more head space. It was easier to see in the bombers. I'll definitely try what you said. Thanks for the tip.

Just a thought because to much head space can cause some oxidation before the beer is fully carbed.
