I know that the only real sure way to test activity is a gravity reading which I will do. Brew day was Friday so Ill check on it next week. I have never had to repitch yeast. Should I make a starter for it also? When should I repitch it?
As stated the only true way to tell is a gravity reading.
How did you make your starter? Seeing activity is not always there in a starter, do you use a stir plate? Was there a yeast cake on the bottom of the starter vessel?
Smack packs do not always swell and if you read wyeast's website they will tell you this is irrelevant.
Airlock activity means nothing other than gas is escaping, if your vessel has a leaky seal it may not bubble at all.
Did you properly aerate the wort? Fermentation can take up to 72 hours to become active.
