Does Worcestershire go bad?

[BigAL]

Probably should toss, but if it were mine...I'd use it no problem. But that is just me.

[Kayelle]

I'd toss it, but I'm a real chicken when it comes to questioning things like this. Back to the old Mantra...."when in doubt, throw it out".

[Rocklobster]

This sauce is fermented so it shouldn't really go bad. But as said before, for two bucks you can have some peace of mind.

If you had it stored in the 'fridge, then most likely cold air in the bottle (which was confined to a specific volume) increased in pressure as it absorbed thermal energy from it's warmer surroundings. Then you got a pop upon opening it.
