I have occasionally tossed out bottles for cracks in the necks. I've not purposefully looked for them but just noticed them now and again. The cracks are usually along the length of the neck, near the seam, but not as straight as the seam in the bottle. Some are very small, and others have been a couple of inches long.
Monday I bottled 7 gallons (75 bottles). This time I inspected every bottle (held it up to the light), and I found 5 that I was not happy with. Three were Sam Adams bottles, the other 2 were Sierra Nevada bottles. These were more sub-surface flaws than long cracks. Tonight I have opened 2 bottles and found 1 with what looked like a small crack (about 0.2" long in it).
I am wondering if I am fatiguing the glass (gradually degrading it with repeated filling/pressure-cycles). Anyone have experience with how glass bottles handle repeated use to the pressure we subject them to.
I have some 400 12-ozs bottles, and am a little concerned that some may be weak enough to fail. Some are not planned to be opened for at least a year, maybe longer.
Maybe I am worrying too much, and this is how they come. I am going to be checking new bottles too from now on. Am I worrying too much?
It's been 10 years since I had a bottle explode on me. Not very pleasant, glass flies and can embed itself in walls and the spilt beer makes a real mess. I really don't want another one.
