Well I'm here and I might as well confess...I like warm beer! And as such I was wondering how would someone kill the yeast after they have done their job of carbonating the beer? I would REALLY like to avoid bottle bombs. I figured that if I heated the bottle of beer to about 115-120 deg. it would kill the yeast, but then I thought that two things could happen: 1. Bottles could blow up from expanding in the water. or 2. Beer chareteristics would be somehow affeted. BTW I would not drink the beer at 120 deg. that's just gross. Another thing that occured to me was if you prime your beer with sugar or other fermentable wouldn't you raise the AC of the beer in the bottle at least a couple tenths?

The yeast will not continue to create more CO2 after the fermentables have been consumed so I'm not sure how the bottles would wind up being excessively carbonated? Most people don't put their bottled beer into the fridge until they're ready to drink it. Bottle bombs are usually made by using excess priming substances such that excess CO2 is made to go into solution.

Seems to me that heating a capped bottle to 120F(seems like a lower temp would take care of most yeast - ever 100F) might not be a problem since there's not a lot of volume change at that temp - caveat emptor. I believe this is how primitive pasteurization was done. I would worry about trying to pasteurize non-filtered beer because you'll be left with a lot of dead decomposing yeast in your beer.

Yes priming sugar will increase the alcohol content of your beer ever so slightly.

Bottle bombs can occur when you use too much priming sugar, but they also occur when you fill the bottles up with too much beer, and don't leave enough headspace.

For getting rid of yeast, probably the best option would be to use a filtering kit (http://www.morebeer.com/detail.php3?pid=FIL40). This will get rid of the yeast, and drop the conditioning time down to a week. However, you'll need a kegging system to use this option....
