sorry, no pictures. but, i'm wondering if anyone has seen this before.
i made a wheat beer with WLP400 - Belgian Wit. let it sit in the primary for 3.5 weeks. when i opened up the primary, there was something strange on top of it! it looked like it possibly could've been bits of krausen. but in my experience (5 batches) i've only ever seen the krausen on the sides of the container...never on the beer.
checked out and it had attenuated an amazing 80%. aroma was fantastic, as was taste. i ended up skimming off as much as i could and bottled.
so my question is - has anyone seen this or something like it? is this beer safe or was that stuff the result of some bad growth? can bacteria in the beer affect the hydrometer reading? perhaps it didn't attenuate fully and it only looks like that. hm.
