Default Explosive Opening... White Labs

I opened an out of date vial and the contents gushed out of the vial, leaving me with about 50% or so of what was in the tube before opening.

It did not smell like beer. I did not think it smelled good. later, minutes not hours, I thought it smelled like bread... but initally it was very yeasty and it stank.

I shook the tube well as the yeast was caked onto the bottom-I got it free then about 5min later, woosh when opening like a fountain in Italy only dirtier and smellier.

It was like a baby mentos experiment.

Is this sort of thing common ? Unheard of?

Perhaps unrelated but in fact, I had two vials, with different dates,
(both out of date)
the exploding vial had nice creamy in color, the no-problem vial, dark dull dead looking yeast.

Has anyone heard of gushing yeast tubes?

It's very common. Think of White Labs vials like a shaken-up soda bottle. Crack lid open just a tiny bit, close, open, close, etc. until the pressure has dissipated. More recent batches don't seem to be as affected. In a couple of months, this will be history, since they are changing their packaging to the flex packs.

Do you think the new packages will help minimize the problem I had?

(hummm I guess you would be able to tell that there is abnormal pressure so I guess so.)

What about smell?

It was nasty...

First-timer &
first time to open this yeast strain, (but not the beer made from it)
Can good yeast - still smell realy nasty and still be good?

Yeah, the yeast in those packages doesn't smell good. I wouldn't worry about it.

Probably fine. Some strains are nastier smelling than others (lagers and Belgians are gross). There could also be some Autolisis if it was old. That smells like putrid beef stew.

Actually that is the word I used to describe the smell, but deleted because I didn't want to check the spelling!

OK, it could be autolysis.... never smelled that until now!

I got showered in it... yuk!
