Only experience I can share with exploding bottles... came from bottling TOO soon! Had a batch that still tasted sweet when I bottled it. Dumped in a normal dose of priming sugar anyway. A few months later, we had bottles that would gush, or foam for like 20 minutes, or explode if they were bounced around too much. It was a high gravity Porter that didn't finish where it was supposed to and I really didn't pay attention to the warning signs.
Listen to your taste buds at bottling time ( ;
