Extremely Large Yeast Raft or Infection

[saltshaker30]

I brewed this a week ago. Added 05- Ale from a package and fermenting at 67 degrees. In short I have never seen this type of material float at the top of one of my beers. I did use irish moss at 15 minutes. Siphoned from kettle to fermenter , and it was a BIAB all grain and the hops were in a bag as well to minimize trub. Looks like protein clumps to me but strangely did not appear till 5-6 days after pitch.

Infection? Or yeast raft ( patch)?

If yeast, worth harvesting?


Thanks for any help. This is my 7th batch... Been lucky so far, as I seem to be the free beer source on the street and all of it gets drank.

Look like yeast...or your beer is growing a brain. Give it the old smell/taste test. Infections don't come without consequences.

Thanks... Smells and tastes great during my gravity readings. So I may try the harvest and pitch one of the "rafts" by end of week.

Irish Moss overdose? How much did you use?

looks like yeast to me.

Looks like yeast mixed with cold break to me. Pinky & the brain must've gotten to it?

Just opened for dry hopping a bucket of Festival Father Hooks Best Bitter which sat in there for 2 weeks and see exactly the same picture as OP posted.
Beer tastes and smells just great, but clumps all over there. Also smaller blobs are floating in wort.

I think I will wait 5 days as prescripted for dry hopping, then if it won't set down, will cold crash the whole batch.

Any other/additional suggestions? 'll apreciate if any

too early to panic -- but, yeah, you're panicking -- understandable

ps - I wouldn't harvest 05 - it's cheap - and consistent from packet to packet

Yeast+cold break love fest imho.

No worries!

thanks for the fast and accurate responses. I scooped the blobs out with a sanitized spoon and dryhopped. looked like break to me too. Amazingly the top was clear last night and already loaded up with large rafts today. I will probably scoop out again before cold crashing to minimize the trub and hopefully get an extra beer or two out of it. I searched all over google pics for a similar picture and none lined up to what I had, so thanks again for the feedback. Now there is a pic out there for the next newbie brewer. I dumped the sludge down the drain, no harvesting here. My OG was 1.065 and now at 1.013 so too high anyways I believe.

You can give hydrometer a try in a glass of water to ensure it shows 1.000
If not so, then you had FG not 1.013
