The 22 oz bottles I got are junk. They are the only bottles that have ever broken on me and when I looked at the thickness of the broken glass, I know why. Super thin, scary thin.

They weren't cheap either!

I got all my bomber bottles off of beers bought at Trader Joes. Niice and thick. I would bring a few back to your LHBS. Let them know what happened on first use so they can address their supplier if they are dangerous.

Just the two lever capper. I have noticed many around around the neck/stem area.
I just went and checked my most recent brew. Altbier with 1% alc boost, made as per published recipe ( Austin Homebrew). After 10 days in bottle, at least one bottle has a horizontal curved crack, easily felt on the outside or the bottle. Opened it at room temp, very carbonated, persisten tall head. Tastes a bit rich, but otherwise OK. I guess the questions are: 1) can "over carbed" beer crack bottles? 2) are these just bad bottles, and if so, is there some way to weed them out before we bottle?

Over carbed beer can not only crack bottles but can cause them to explode. Where did you get the bottles?

Just wondering, didn't notice a mention of this. How long was the beer in the fermenter?

all my bottles are my own sierra nevada empties, handled gently. No excessive mojo to apply caps,no caps bulging, no excessive carb when opened. Beer seems quite fine. I saw on "How its made" that factories use black light to detect cracked bottle. I'm going to get out my old poster light (now there's a blast from the past!) and see if I can find any more defects.

10 days primary, 10 days plastic carboy, then bottled. The partcular recipe I used was one designed to ferment and card rapidly from Austin Homebrew.

I'm going to second the casting lines opinion. This isn't a multi-layered windshield we are talking about. If it were truly a crack, it would have busted under pressure already.

I respectfully submit that in my case, this bottle has a partial crack. The defect is easily felt. I'm suprised it didn't just pop as well. My best guess is that some kind of pre-existing defect was just exposed by the stress of handling. I will try to make a photog and post it for your inspection. I will not re-use this bottle.

I've found a lot of bottles with this problem; vertical indications down the neck. Certainly looks like cracks. I don't know if the bottles are made that way or if the cracks develop with pressure cycles (fatigue cracks).

I just toss them out. Gives me an excuse to drink more commercial beer to replace the bottles.

I've found a lot of bottles with this problem, dozens, maybe a 100, but I have never had a bottle break in this area. I'm suspecting it is an indication from the manufacturing process and not a real problem.
