I just transferred my kolsch to the secondary yesterday. I checked it today, and the top of it is covered in white spots, about 1/2 to 1 cm across.
Unless this is some known phenomenon that is caused by my yeast, I assume that I've got mold growing on my beer.
Are there any fungicides that won't kill yeast? Has anyone encountered this before? Should I chuck the batch and start all over?
(This is horribly embarrassing, too - I'm a biologist, for crying out loud! I regularly grow bacteria and cell lines in the lab without contamination of any kind!)
