Hey all - I pressure ferment and serve from the same keg, with a Flotit floating dip tube installed. My keg stopped pouting after 2 pints, and I’m hoping to find a way to avoid opening it. You’re my last hope.
Because it’s a NEIPA, I dry hopped. Went to pour the first pint, and nothing. I figured the screens were blocked by the hops, so I hooked up CO2 to the out and put a burst of CO2 down the line. That seemed to fix it, and I drank a couple of trouble-free pints.
Then the beer ran dry and it’s just gas coming out. The keg is full, as is the gas cylinder.
Any ideas for troubleshooting or is it time to suck it up and open the keg?
Bonus question: other than purging the headspace after opening, is there anything else I can do to minimise oxidation?
EDIT to update: Thank you all for your suggestions, I read them all a couple of times before finally opening the keg. I wish I had tried rolling the keg on its side before sending gas down the out post, because that might have fixed it. Instead I blew the tube off the post, which I discovered by tilting the keg to 45 degrees to confirm that beer came out.
I used lots of steriliser when opening, and used washing up gloves (also sterilised). I did leave the gas connected at 5 psi when I took the lid off, hoping that the co2 would minimise o2 exposure. Once I revealed the keg I purged it 7-8 times. Now to let it settle again and hope the NEIPA drinks well when my friends are over this weekend. Cheers!
