Hi I am brewing a dark ale and I bottled half the carboy(after 4 weeks in secondary) since I ran out of bottles I put the airlock on the carboy with the remaining beer in it. 7 days later I see a white layer form on surface of the beer with few white bubbles The white formation resembles that of a spider web. I have a bad feeling this is MOLD and my beer is contaminated. Can anyone please help !

I will add the official request.

But seriously like stated in earlier posts without pics its hard for us to tell you what it is.

Just think of all the antibodies you'll get from drinking that mold, clear up that sinus infection. It'll be fine, the alcohol will kill it.

Another way to tell is to take a sample. If its sour its bad, if not then it should be ok. By taking a sample and tasting it you should be able to tell. If its bad, just spit it out.

However, if it is bad, Im not sure what the solution to this problem would be.

You should start your own thread. It's very poor etiquette to do this in someone else's thread.

Anyhoo...

Wild yeast / Brett infection. It will slowly and increasingly get some odd flavors. If there is lactobacillus in there, it will also get sour.

Taste it now. If it still tastes acceptable, there's a chance. If not, I would dump. If you like funky/sour beers, you can play with it for a while and try to salvage something weird, but from experience I can tell you that these things don't serendipitously turn into a good beer.

Your only hope is to bottle it right now, carb for a few weeks, and chill forever (until you drink it). You might get gushers, but if you are lucky you won't. Or keg if can do that. If you bottle now and leave it at room temperature, you will probably have some serious gushers / bottle bombs later.

Yes, that is an infection. Look at this thread. If you can spare the fermenter, throw it in a closet for a year. Probably want to ditch your soft plastics (i.e. racking hoses, etc.) and sanitize everything extra well.

That my friend is an infection.

Couldn't he just sanitize a very fine strainer, scrape it off the top? Then let the alcohol take care of the rest?

No. The fungus that is causing that would be found through the beer. The only reason you see the pellicle at the top is because the fungus forms that in the presence of O2.

Well, I've never tried to scrape anyway, but I'm 99% sure that wouldn't work. And, if you try anyway and are wrong, and you get bottle bombs, you'll be really sorry. Those things scare the crap out of me.
