I racked my Rasputin clone yesterday and noticed that the inside of the carboy was covered with what looked like bacteria colonies. The beer tastes fine which leads me to think that it's yeast and not bacteria, but i've never had this happen before. I took some picures with my Gen1 iPhone, so the quality isn't great, but you'll get the idea. Anyone have any thoughts? Happened to anyone else?

I also would like to know the answer to this, I have had the same thing happen, but on the in side of bottles. Made the beer barely drinkable bitter. Along with this it was quite estery/fruity/banana like. To the op does it seem that all of that film is made from little dots? Does it take scrubbing to get it off? The stuff I had did not have any defined edges like those above, but just a even coating all over the inside of the bottle.

It was really easy to get out. Just swirled around the trub at the bottom before giving the carboy a rinse. Like i said the beer tasted fine, other than having some esters in it from fermenting at too high a temp. The edges were pretty defined. They do look like little colonies of SOMETHING. But no off flavors or aromas.


Hmmm.

All the beers I had tasted fine out of the carboy, but there was no film on the carboy, only in the bottles. I just opened one of my latest batches, and dawg gone it, it taste bad, and has the film on it. I have pictures, I will try to post them in a little while.

Hope this works:
If anyone has any Ideas, I have had this problem in a bunch of my batches, and I can't figure it out.

really interesting looking. Not brewer's yeast. Doesn't look like any of the pedio, lacto or brett I've played with either.

It reminds me of the film left over after I racked a Berliner Weisse, which has used Wyeast 5335 Lactobacillus. But I didn't take any pix, and it could be totally different.
If the beer tastes fine, RDWAHAHB
