I brewed 2 batches this weekend. 1 kicked off just fine and the other hasn't seemed to have done much yet. I used some BRY-97 from a LHBS that had a BBD of 5/2015. Pitched it Saturday afternoon and I didn't see any activity 24 hours later so I went back to the store and the guy gave me another BRY-97 with the same date free and suggested I pitch that again (I was skeptical). I did this yesterday and it has almost been another 24 hours. I'm getting little to no airlock activity. I did buy some liquid yeast and I'm debating on whether or not I should pitch this here shortly.
At what point will my batch become a total loss? Should I pitch the liquid yeast that I bought? If I pitch again with the liquid yeast, do I need aerate the wort or can I just dump it in?
