I believe I'm not much of a n00b in brewing Saisons (I brew them pretty often) but this time I'm witnessing a natural phenomenon I haven't seen before.
Two Saison batches (M31 and BE-134 yeasts), bottled at the same day a week ago show what I can describe as a thin pellicle in bottles (sorry, no photos). When a bottle is opened, a rain of powder particles falls down from the "pellicle" to the bottom. No taste/flavour changes, no gushing as far as I can see. Both beers are already perfectly carbed up and ready to drink. Both are attenuated pretty high (1.002 & 1.003) so I don't think there's much nutrition left for any wild bugs that might infest the bottles despite my professional-grade Peracetic Acid disinfection regimen.
So I can speculate it's rather Saison yeast floating on the surface after a week-long bottle conditioning at a highish (25C/77F) temperature.
In dozens of my previous Saision batches with the same yeasts at the same temperature I've never seen such a behaviour.
What's your experience, have you ever seen Saison yeasts floating to the surface and forming a sort of pellicle?
