how much pressure to expect when opening swing cap
It has been a week since bottling and I opened a test bottle today. When I pulled the lever to the swing cap there was a lot of pressure and a loud pop noise... like opening a champagne bottle. Is that normal or should I be worried at this point?
TIA
100% Normal. I've never had (and my other brewing friends haven't had) a fully carbonated swingtop that didn't.
I once had a growler pop open so hard that the gasket flew off. Scared the snot out of me and I was terrified that I had an over carbonated batch and that I was going to have an explosion... I couldnt bear the thought of throwing the beer out so I immediately put all my swingtops inside a big rubbermaid container with a snap on lid (I got the idea on this site but I can't remember who posted it..)
I was wrong, the batch was fine, nothing blew up and I realized that sometimes they just do that... my theory is that that noise is the sound of happiness.
We have a little tradition here in my home. Any time a swing top is opened the crowd must hush. That way we can all fully appreciate the "sound of happiness". Sometime we get duds, where one bottle didn't create a good seal or just didn't pop too loudly, but everyone smiles and cheers at a good loud pop.
A swing top is much like a wine or champaign bottle, just with a rubber O ring and ceramic cork in place of a real cork, so a good loud pop is to be expected.
No matter what your vessel of choice is, its always comforting to get the CO2 sound when opening the beer up after conditioning.
Of course if you are kegging, you have to pretend the the sound is there.
I am so proud of myself. I figured out how to spell the noise of happiness.."krrrrrsssssshhhht"
