Hey all -
I bottled my first brew around about 3 weeks ago. Last week, I put some bottles in the fridge for a couple of days to give it a taste test. I started to notice that the bottles in the fridge were getting cracks in them. I looked at the bottles still in the closet and noticed the majority of those also had cracks in them. We are talking hair line cracks forming vertically on the bottle. I was afraid that they were overly carbonated so I opened the ones in the fridge carefully. They were not overly carbonated and actually had a perfect amount of carbonation in them. I threw some other cracked bottles in the fridge, tried them out tonight and these were not overly carbonated either.
I followed the instructions perfectly (mixed the priming sugar in with the brew) when bottling and have not been rough with the bottles either. These were brand new 22oz bombers purchased from the LHBS that the only thing I had done with them was sanitize with a diluted bleach solution. Since these beers were not bottle bombs or overly carbonated, does anyone have any idea why the brand new bottles would be cracking like this?
Would they be safe to use for future uses if no glass has physically been chipping off the bottles?
Thanks for the help!
