Check this out:
This juice bottle is all fogged up, bears multiple cracks around the threaded area, and the mouth's edge is all ragged and chewed up. It's started leaking a while ago, and today, the dripping tip popped out, pouring juice all over the place.
I have a few other bottles that are degrading like this one has - but haven't reached that stage yet. What they all have in common is, they hold juice that has malic acid in it. This has happened with only one fill-up of soured juice: I refilled this particular bottle 3 or 4 times with unsoured juice before, and it didn't crack or fog up.
