I know someone with the same problem right now. They as well carb'd at around 30psi for a few days and I think that the beer is now over carbonated. I told them to bleed the pressure from the keg and then let CO2 escape from the beer to re-pressurize the keg. Told them they may have to...
I store overbuilt yeast in mason jars and I simply put the ring on loose for the first few days so that if pressure does build up it is released by pushing the sealed cap up. Once you know the yeast is dormant you can tighten up the ring and you're good to go.
I'll be in Austin Texas for a few days near the end of June and will be around the JW Marriott Hotel. Any suggestions for a place that has great beer/food and within walking distance will be appreciated. Thanks!
I found this thread on the Canadian Homebrew forum for a Hawaiian Pale Ale and have it on my list to brew.
