searched around and saw some similar threads but they didn't have photos attached and im not sure if this is same issue

this was taken yesterday as i went to rack from primary to bottling bucket

irish red ale ~4 weeks in primary - avg temp ~65*

i tried to rack from underneath and to the side but once the wort starting being siphoned it swirled it all up

the clumps of yeast look normal and weren't of concern but i haven't seen the layer of film on my last two batches

is this an early sign of infection?

Doesn't look like an infection to me?

Looks good to me, probably some hop residue and foam from yeast

Oils from the hops would be my guess. It's not an infection IMO. Rack from beneath it and have a taste. You'll know whether it's infected.

Tasted fine. Wasn't there 2 weeks ago when I checked fg

Was thicker than just a hop oil slick which I have noticed before

I figured if it was anything serious it would have tasted off but am curious what it could be.

I have the same stuff on my oatmeal stout. I tried to cold crash it but it's still there. Looks like the yeast is still eating but my numbers have been met. OG 1054/FG1010. I swirl it and it drops but then comes back up. Beer tasted fine after final gravity check.

For quite a while after the fermentation the beer still has CO2 dissolved in it and it will continue to bring stuff to the surface with the bubbles. Nothing to worry about as long as it tastes good. You are very unlikely to get an infection in your primary unless you are really sloppy about sanitation.

I hate to go against the grain here, but it's got the "broken ice pack" look that some infected beer seems to get (lacto or something). If it was a huge double IPA maybe it could be oil from all the hops, but I wouldn't think an Irish Red's simple hop bill could provide that much hop oil.

Could still end up tasting good, though. Only one way to find out!

I had the EXACT same thing last night and was worried that it might be an infection.

It was the first time I dry-hopped every.

Last night was 3 weeks in the primary, and I bottled it.

Tasted fine to me though.

I had a similar issue with an interrupted brew day on the wort. Turned out fine.

As long as it tastes ok don't worry
