I didn’t realized it but I bought a white labs American ale blend vile that was expired. I read on it that if it’s past the best by date, that a starter was necessary. So I made one last night and I never saw a krausen.
I swirled through out the day and didn’t really see any activity. How do you know if it’s a good to Go starter or if the yeast is in fact dead?
I have a S-05 dry pack just in case. Thanks
