Picked up a vial of White Labs yeast from my LHBO on my way home from work, planning to brew tomorrow. Got the yeast home and it was kind of caked on the bottom of the vial. It did not want to be shaken up evenly. Now, it's gotten a chance to warm up, and it's still a bit chunky. It's not dissolving nice and evenly like all the other yeast I've gotten before has.
The yeast is White Labs 540 - Belgian Abbey IV.
Is this yeast still good?
