I've always pronounced it "Why-East," but that's just because that's how it looks like it should be pronounced. "Why-Yeast" doesn't make sense to me since there's only one "y" there, so it would have to be either "Why-east" or "Wh-yeast,"...
Why yeast?
Wy'east is the native American name for Mt Hood near where wyeast laboratories is located.
I pronounce it wye-east but i have no idea if that's actually correct.
Whitelabs ...
"elephant", of course...
(sorry. monty python flash-back... )
I actually thought it was pronounced "why-tlabs".Or is it "why-labs"?
To those that say Why East, Where did the "h" come from? Wyeast????
What do they know??Here ya go. Straight from the company. Why-east. I'll probably continue to pronounce it wye-yeast, as I have for years.
