Only sometimes.
Haha, that looks like a little ghost! Cheers.
Looks like there are plenty of happy yeast!
My beer usually says “Drink me!”
Next question - what’s the fermenter that uses a universal bung upside down?
Long about the end of my long workday, if I listen carefully I can hear my beer calling me from my fridge! 
I’m curious about the upside down bung as well… and what is the dial? A timer? Never seen that one either. 
OMG, I’m sure talking, but I do everything in my own way
It’s a big mouth glass carboy from kegco. I didn’t like their stopper so I flipped mine upside down and it was secure. The dial is actually there to set the date, so you know when you started fermentation.
I liked these big mouths but had one break on me when trying to get the lid off. I have one more and am afraid to use it now. I broke two in a month, the glass is too thin.
I transferred to secondary and pitched Brett. So it can be the ghost of Brett.
wow, never saw anything like this before ;D
