White chalky stuff

I've had a white filmy,chalky paint looking film on top of some of my secondary ales from time to time. I thought is was mold and now iam not sure. I was told it could be old yeast cells. has anyone else experienced this stuff on top of the secondary after having sat for a few weeks? Thanks

I have what sounds like the exact same "thing" on top of my stout which has been in the secondary for about 3 weeks now. I don't see anything growing so I can only assume it's not mold. I'm going to taste and bottle it this week, hopefully it turns out OK as I'm looking forward to it.

it is most likely clumps of yeast surrounded by tiny bubbles... this was discussed recently here: http://www.homebrewtalk.com/f39/secondary-white-stuff-6811/?highlight=white+secondary

I actually had the same thing on my last lager in the 2ndary.... Im pretty sure it was just yeast.

Thanks guys for the feedback. I am much relieved. Sorry about starting another thread, but I just joined and didn't know this came up before. Thanks again.
