After some head scratching I noticed the vial had a best before date of March 20 2009 and I just bought it last Thursday. I assume it had been stored in the vendors fridge the whole time until it was sold to me.
This is the first time I've used this yeast strain (White Labs WLP840) so is the yeast experiencing a long lag period or is it kaput?
If it's fermenting out, it's alive. It's good you made a starter, so that you could grow some viable yeast. Give it a few more days. Now that it's going, I bet it'll finish quickly now.
