I have some White Labs witbier yeast. It's at least 6 months old, probably more like 9-12. It's from a previous batch that I just scooped out of the trub after primary fermentation. It's been in my fridge the whole time.
I made a starter and it is doing well.
My question is: Is this still okay to use? It's been kept cold the whole time, and it was fresh from the first batch. And like I said, the starter is doing very well right now.
