Founders imperial stout explodes in cellar

[Mhill2079]

Just what it says. Imp stout from this year just exploded in my cellar. 66-68 degrees pretty steadily. Any ideas? I've stored beers down there for years and never had this happen. That particular beer probably hasn't been disturbed for months and all of the sudden today a side of the bottle blows out and beer is everywhere.


I'm afraid for all my other beers....

It happens every so often. Store here had a Barleywine (forgot the bewery) explode on the shelf a while back.
