Default Possible infection?

So, I brewed up a Chocolate Stout last Monday and it started off great, but for the last few days since the krausen disappeared, there is a milky sheen with bubbles both large and small all over it. I've tasted it and it tastes fine, almost like Young's actually. There aren't any off flavors or smells. I was curious if it could be from the lactose I used. I've never used lactose before so I'm not sure if its a common occurence with milk stouts or not. I'm a freak about sanitization, so it really bothers me that this could be an infection. Any help would be appreciated.

Sounds like it's just the remnents of the krausen, and maybe oils from whatever chocolate form you used. Lactose won't "do" anything to the surfact of your beer, or anything. It just dissolves in the boil.

We really need to see pictures, but since 99.5% of these threads turn out NOT to be infections, I'm betting the same will go with you. Fermentation is often ugly, and smelly, and that's when it is perfectly normal.

Yeah, I'm working at the moment or I would've posted pics. When I get home I'll post pics. It just bothers me because in all of the batches I've made, I've never had this happen. I'm sure its nothing, but I still had to seek some advice. Thanks Revvy!

I don't know, large and small white bubbles sound like an infection to me...

Does it look like this:


or this:

or this:


However I agree it is hard to say without pics...even if it is infected it can still be safely consumed...you just might have to step up your time table a little bit!

Yeah, it looks like the last pic, just not as white. What is it?

I'm not an English teacher but wouldn't the correct term be contamination. Not infection.

Dude those pics are f'ing nasty. If those aren't colonies of bacteria I don't know what is. Rule of thumb - if your beer looks like the rind on some brie cheese, your sh!t is contaminated.

While I agree that its nasty, that doesn't really help me much. Is it worth saving it or should I toss it?

how long has it been fermenting?

A few words of advice:

post some pics
take gravity readings.
quit staring at your fermentor.
do not toss unless your beer tastes like the wrong end of a dead buffalo
