this can happen if you bottle with dme.Although i have never seen this happen when i use it.It could mean infection.But i bet it will disapeer over time.Ive bottled up beers with an obvious flakey filmy substance on top and even from those i had those turn out great.I would just keep an eye on them and try one every week and check for overcarbonation. Its even possible its mold from the apricots,but dont be alarmed and dont dump them.Im debating weather my funky batches were mold or infections because my findings were that the filmy stuff disapeared overtime and i still had good beers to drink. Whatever filmy stuff i had disapeered or didnt effect my batch with condtioning.Just be carefull some infections can lead to bottlebombs. I have since let those peculiar batches sit and have no negative effects from them with many months bottled.
