I have brewed a few batches all extract but haven’t ever seen this white cloudy soap scum like stuff on the top. The beer smells good so I assume it’s gonna taste good just curious if this is infection or normal? This was an extract kolsch and it has been fermenting for 3 weeks then I crashed it to 44 degrees the last few days. The recipe didn’t say to add the malt late so I assume that’s why it’s dark.
Surprised no one else has jumped on this the day you posted. But here's my opinion...
Whether or not a beer in the FV is infected doesn't change anything I'm doing. I'm still going to sample it when I've deemed it ready to bottle.
If it tastes good then it gets bottled.
If I can't decide what it taste like, it still gets bottled. And I'll decide when it's carbonated and conditioned whether it's worth keeping. And that conditioning might be for months.
If it taste foul, it gets dumped.
It possibly is a infection. Few are poisonous or toxic in beer. But there are extremely rare exceptions. When you sample, don't go overboard on the size. If you decide it taste good but is infected, then when it's ready for prime time, don't drink yourself silly on the first few glasses of it. Have one glass and then see if you get the runs or any other adverse affect the next day.
You'll have to decide if your morals allow you to get Mikey to try it.
