The proprietor at my LHBS gave me an unsold Wyeast 1968 smack pack that was well over a year old. I made a starter for it just to see if it was still viable. It was not viable.
Now I need to make a WLP001 starter for a batch I'm brewing this weekend, and I'd like to use this failed starter for that. My understanding is that dead yeast make for good nutrition for active yeast. Would it be a bad idea to add a little water to the failed starter, boil it for 10 minutes, and use it for the WLP001 starter?
