Hi All. This is a two week old Bavarian Hefeweizen - brew was all-grain.

I've looked at other threads and am still not sure if i have an infection, or just a byproduct of the brew. I have a thin white film on the top of the beer. This beer has not been racked, it is fermenting in a stainless steel conical, with temp controlled at 65F during the primary phase, and 70F after dumping the trub.

I finished cleaning the conical during the last 15 minutes or so of the brew. My normal process these days is to use warm / very warm water with PBW, followed by warm or very warm rinse, followed by Starsan. I also make a point to disassemble the dump / racking valves and submerge these in Starsan, usually AFTER the vessel has been cleaned.

This is an SS brewtech chronical 14 gallon - it's only about a year old and has no rust spots.

I pulled a sample to taste it, and it is not bad at all (and I've brewed very bad batches before, so unfortunately i usually can tell when there is no hope).

The gravity is 1.008 - and it is very cloudy, although I feel the appearance is probably normal.

My main questions are what to do next - do folks recommend I cold crash & keg now? would it be beneficial at all to purge the headspace with more CO2? does anyone recommend trying to skim this stuff from the top?

I'm fairly sure that i've seen this film develop on this recipe before and the beer underneath it turned out to be just fine.

Any help is greatly appreciated!!

If it tastes good, keg and be done with it. Lacto, Pedio, and Brett take a long time to affect the taste of a beer once it has alcohol in it (Brett maybe a couple of months, but the others are much longer), and I think Lacto and Pedio prefer higher temperatures. All 3 are stalled at cold temperatures.

If good keg and cool it. Just don't take a couple of years to drink it.
