Could be. It's 8 days into fermentation. I've had an infection with a raspberry ale that looked similar to this but being I've never run into one with a mead I was concerned.
I can't imagine that being a pellicle at 8 days. To re-assure you on top of that, Pellicles are pretty easily broken and the amount of bubbles and off-gassing from primary would break it before it even formed. I'm 95% sure this is just yeast.
Ok. Well just smelled it, no off scents they dropped off after taking photo, will see if they return. Was just a sight when I opened, very large. Almost filling the entire head space. Oh well panic hour over.
Smells of raspberry, alcohol and yeast. No off scents. After opening lid they fell off. Like I said in previous post they were very large, then went away. I had a very vigorous ferment for the first 5 days. Lalvin D-47 used for yeast.
