A microbrewery here in Northern AZ recently started canning and I was able to get some down here in PHX. All the cans so far I have opened have had no 'pfft' and extremely low carbonation. They taste fine but not much carb. When they were bottling years ago it was all good. I emailed them to ask if they knew there was an issue or they were changing it to be more like a 'cask style'. Here's the brewmaster's response:
You are correct, the carbonation level has been lower in the can than in bottle. We have been wrestling with just the right level. Some of the cans remain in Northern AZ and some go south. If the levels of saturated CO2 are perfect here (2.5v), then due to the change of atm pressure, the beer seems under-carbonated in the valley. If perfect at low elevation then it gushes up here. I am trying to nail down a happy medium. You should expect higher levels in the future. Thanks for your support!
This doesn't make sense to me. If you carb your beer to a certain level why would it change in a sealed can when taken to lower/higher elevations? I've never come across any other can of beer like this before. I gotta wonder if I'm getting a straight answer...
