Reading here and elsewhere about gusher infections.
Over carbing can cause gushers but, as I understand it, this sort of gusher mostly subsides once the pressure is relieved. Whereas, a gusher infection will just keep foaming and foaming and foaming out until most of the bottle is gone.
As I also understand it, early on you may not even be able to tell the difference between early stage gusher infection and overcarbing because the gusher infection can take a while before it really affects the taste.
What's going on for you may not
be a gusher infection, but that's what it sounds like to me.
There is plenty of reading on it here... paste the line below into Google, et al. search.
