Hello, I recently bought a couple all grain kits, I made the horrible mistake of throwing the hop kits into the freezer for when I am ready for them, now made the realization that the yeast packs were in there as well, it was a total of 24 hrs. Did I just destroy the yeast?

Dry or liquid yeast?? Dry yeast should/could be ok (check the packet, if it says you can freeze it, you're ok). If they included liquid yeast, chances are you have little, if any, viable yeast left. Make a starter and see if anything happens. If nothing does after enough time has passed (at least a few days) then assume the yeast are all dead and you need to get new yeast.

BTW, in the future, I wouldn't put ANYTHING in the freezer except for hops.

Might be alright. Proof it if it is dry or make a starter if it is liquid.

Hey, it was dry yeast. I normally don't do stuff like that, but I did, sucks. Oh well maybe I will contact the manufacturer.

Should be instructions on proofing the yeast on the packet, or on the manufacturer's web site. The packet should also have storage parameters listed on it. At least the packs of Lalvin yeast I have do.

There's a very high chance that the dry yeast will be ok after just 24 hours in the freezer. Just put it into the fridge now and proof or make a small starter, before you use it. Maybe get a spare packet to have on hand, just in case it didn't make it.

Test it by adding it to water and see if it starts to bubble.

If it is liquid yeast you need to get it out ASAP. Liquid yeast doesn't do well freezing in plain water but is almost certainly doomed in a frost-free freezer where it cycles from thawed to frozen over and over.

Don't keep us in suspense! Did you proof it? Make a starter? Let us know how it turns out. Chances are you won't be the last person to do this and your experience can help someone else down the road!

Good luck!

Sorry, no I have proofed it. Talked to the guy that sold it to me from hopdawgs and he said it would be fine, liquid yeast is another story. I ended up removing it within 24 hours and placed it into the fridge. When I am ready to use it, I will rehydrate it. He said that his mother used to freeze dry yeast all the time, basically freezing puts it into a dormant stage, where as heat on the other hand would kill it. I have been working night shift and plan to do a brew this weekend. Will post again when I have finished the brew and have some action.
