I purchased WLP002 today with an expiration of 11/20/11. 60 minutes out of the fridge I'm ready to pitch, shake it up and it looks like curdled milk. The more I shake it, the smaller the curds get. It never mixes with the clear liquid. Let it sit for 30 seconds and it gels back into one layer of yeast. Each shake only produces curd like pieces.
My LHBS says it's very healthy and active and not to worry. I went back home and pitched it, it looked like curdled milk sitting on top of the wort.
It had the smell of yeast, not spoiled from what I can tell
What do you think? RDWHAHB or am I in trouble?
