Possible infection?

[andejos]

Brewed this Dec 28th. It is still fermenting but wasn’t sure what these spots were. BTW this is a bells two hearted clone. Any thoughts?

Yeast rafts. Not a problem.

Cheers

Just yeast. That will drop out in time. But I wouldn't let that sit around too long. You want to drink that one fresh.

totally ok. if you're not sure send it to me and I'll dispose of it safely

What are some major telltale signs of a problem? Outside of a chunk of mold floating around, what should one keep an eye out for?

 

[RPh_Guy]

Contamination may cause one or more of the following:

-Unexpected flavors and aromas
-A film on top of the beer called a pellicle
-Visible mold (if too much oxygen)
-Overattenuation, especially if bottling
-Slow or stuck fermentation
-Cloudiness

All of the above, and check out this thread for real pellicles, intentional and not so much:

Yet, those are fine. Yeast floats freaked me out the first time I brewed in a transparent fermenter.
Enjoy!

Everyone’s answer was solid. IPA, all generously hopped beers really, are very difficult to be infected. Not saying they can’t but originally hops were added so the beer wouldn’t spoil during its overseas voyages
