White Labs vs Wyeast making a starter?

[butterpants]

I've prepared a bunch of starters using Wyeast smack packs and been successful. Never done one off an agar slant/White Labs vial. Any different procedures necessary??

Nope, just the same.

thank you!

I guess I should mention that for a slant (not smack pack or vial) you want to start really small, like 50 ml, and step up a few times.

Making the starter is the same the only difference is to slowly crack the cap on the vial to release any pressure.

This is a must. You also have to shake the ever loving crap out of those vials to get the yeast back into suspension most of the time, too. Otherwise, it's all the same.

Any specific reason (other than avoiding a mess) to release slowly? Is there enough pressure difference to cause cell damage with a rapid drop to ambient pressure?

No, it's just to avoid spraying yeast all over the place.

LOL, this. I hadn't used white labs in 10 years. Forgot about the pressure build up. Quickly opened up a vial of the San Diego Super strain after shaking. Let's just say I didn't end up brewing that weekend.
