Over-carbonated

I don't have any experience bottling, but, assuming #3 is it, it sounds like that would be fine at this point, provided you follow proper sanitation procedures and take appropriate steps to minimize oxidation (which, I guess, goes without saying). It's reasonable to assume that even the S-04 is done by now. This will not be very exact, so you may end up with inconsistent carbonation from one bottle to the next, but they should all be closer to where they should be, assuming they're equally overcarbed.

 

I have never needed to re-cap but sounds like this is where your at. If your bottles are not blowing up I would pop one and re-cap right away. Then wait a couple days and crack one. If it is still over carbinated wait 10 seconds before you cap the next one till you get to where you want to go. Sanitize your caps! Good luck!

 

I think the moral of the story is to take two gravity readings, three days apart, before deciding that attenuation is finished.

 

I would recommend recapping.

In my case I had swing-top bottles, so it was fairly easy. I put on eye-goggles and codpiece then "flipped the bails" . . . which blew off and landed on the other side of the room. I had no gushing, but extreme off-gassing. You could not boil a liquid and get any more bubbles. After about two minutes of watching the show, I re-capped. In theory, the headspace of the bottle will remain mostly CO2, so you should not suffer oxygenated beer.

Best of all the batch was saved. I can now open the bottles without having to stand behind a barrier . . . the taste, which was good before, remained good.

Your idea to do a couple of bottles, wait, and re-evaluate is sound. My only other suggestion is to have chilled the bottles for at least 24 hours before opening. Please let us know how it turns out.
