I had my first bottle bomb ever yesterday, after 3 years of brewing. I've had some bottles break during opening, some while bottling, and it's usually not a big deal, though sad. Having one shoot out all over my laundry room is a much bigger problem that I'd like to prevent.
How many times do you re-use bottles, and how do you count if you do? Is there any other way to evaluate the condition of the bottle? This one was a 22 oz bottle bought at my local homebrew store 3 years ago, and appears to be the weakest type of bottle I use.
EDIT: Just for reference, I sanitize using iodaphor in tap water, so I don't believe there's much temperature shock.
