Being fairly new at brewing I find that something different happens with every beer I brew. My current Pale Ale was in the primary for 2 weeks and now is in the secondary for a little over a week. My inquiry is about tiny bubbles that have formed on the surface. They are not large by any means but I was wondering if this may be the start of some kind of infection. I have ample headspace (6 gal carboy) and did sort of jostle it a little bit yesterday. Any ideas?
