try to proof it before you start brewing... if no action..no yeasties
This is an honest question... Do you need to put dry yeast in the freezer?

Dry yeast is best in the fridge, not the freezer.
When she put it in there, was it in an envelope or bag or something? Or just in the sachet it came in?
24 hours doesn't sound terribly long, but in a conventional freezer, it is subject to temperature up-and-down spikes, which cause ice crystals and repeated defrosting, which puncture yeast cell walls. But I do not know if this would affect dry yeast.

The good news is that if you only have half the viable cells it is still ample.
I'd proof first. Can you get a new pack anywhere local?

actually 2 packs of S-05 froze. I will pitch them both. Hell of a deal for my first time to go allgrain.
Well, if it were me, I wouldn't pitch them both just out of the package. I'd rehydrate one tonight with just a little tiny pinch of DME mixed in some warm water. If it foams a little, you're golden. If not, I'd had just the smallest pinch of sugar. If it foams, it's good. If nothing, I'd buy fresh yeast.
I don't think freezing dried yeast is as bad as liquid. I would agree with proofing it first though just to be safe.

23 hours no airlock activity ***BUT*** starting to see particles rotating through the wort and maybe some krausen starting to form. I hope. I sprinkled it directly on the wort. Is us-05 a slower starter than nottingham ?
Not usually. My 08.08.08 started bubbling in a few hours with rehydrated S-05. Thats been my general experience with dry yeast is that they start quickly within the first 12 hours or so. However if the package was old or not entirely viable it may take longer. Give it 2-3 days before worrying too much.hotammo said:
