First batch, been in primary fermenter for 2 weeks, just opened lid to dry hop and saw this. Wanted to see if that looks okay, sort of a film at the top. http://imgur.com/dQghX0n
How many bubbles coming from the airlock? What's your kit/recipe? ps - Oh yeah, stop messing around with your beer unless you're sure it's ready to bottle, etc. Looks like it has a way to go yet. Let your bubbler and your hydrometer tell you.
I agree...maybe ferm got a late start? Maybe give a little longer before dry hopping...I see evidence of off-gassing there at the very least...
That's why I like my carboy. When fermentation takes off it looks like a bad ass lavalamp of sorts that also emits hop scents into my guest bathroom.
