I've got a similar issue right now, a couple of White Labs vials came really hot. I've already brewed with one of them, having made a starter that was slow to take off but eventually did. The actual pitch into the brew had a nice short lag time, but then again it was a 3-gallon batch and an average gravity beer.
The other one, I have the starter going right now, and it's not been doing that great... it looks like it had a small kraeusen that I missed, but not a whole lot. And it took nearly 4 days to do that. There does appear to be a fair amount of settled yeast, I think, so that's good. Most concerning of all, though, this is going in an IIPA with a target OG around 1.080-1.090. So I'm a little worried... should I decant this starter and pitch into another starter to step it up, maybe?
