Fellas... this may be a dumb question/topic but I noticed in my brew quite a few vials have these tiny bubbles of air or something? not quite sure but they don't seem to be absorbed into the bigger bubble of air. Probably just little air bubbles? This picture is of Primo E 200mg/ml. I'm wondering if this is normal, I used the syringe filter method into pre-sterilized vials. Recipe was 2% ba, 20%bb, CSO.
