Dry yeast expiration date
« on: December 11, 2020, 12:45:33 pm »
LHBS had some outdated S-189 lager dry yeast dated 12/18. At $9.95 a package I can see why it has sat around.

Thoughts on viability and vitality

I have used very old dry yeast with success before. But, I don’t know how to know viability without a starter or pitching in your batch and waiting. Are you feeling lucky?

I hope he wasn't selling the expired yeast at that price.  My LHBS sells me recently expired yeast at over half off (usually for $1 or $2, if just out of date).  If you could pick up a couple sachets of the 12/18 exp. date, I would give it a try (again only if you get it deeply discounted).

I am not sure how he did it, but Jamil put together a viability factor for dry yeast in his Mr. Malty calculator....

I know a fellow brewer who routinely uses dry yeast ~2 yrs past its printed expiration date. He reports no problems with it. I have not used dry brewing yeast this old but I have used bakers yeast that was 6 yrs past its printed expiration date, and it made perfectly good bread. Yeah I know, totally different strains, not an apples-to-apples comparison, but the point is that dry yeast is hardy as hell. Two years old should be fine.

Feeling lucky? Not at that price or the not so generous $2 off discount!! LOL

Even though I feel like you’d be OK even though it’s past it’s expiration, you can get S-189 for $8 + free shipping from Label Peelers. It won’t be expired. Unless -189 is critical to your beer, Diamond may be an alternative at $5.30 + free shipping.

Depending on the wx where you are, it might be cool enough to even risk ordering liquid yeast online. I won’t do it in the Summer here in AL but in the winter I am not as concerned.

My feeling lucky comment was in regards to your question “Thoughts on viability and vitality”. I guess I assumed you bought it. Sorry.

I found it on Adventures in Homebrewing for $5.36 that was with shipping. I also visited the Fermentis website and they claim the yeast when properly stored ( i think it was 15c) will last 36 month.

I haven't used S-189 and I am looking forward to trying it.

No worries!! I probably would have had he given a much better discount. He wanted $7 and I found it on AIH for $5.36

Cheers!!

Properly stored, I see no problems using dried yeast expired for 2 years.  I've done it and it works fine.  You can double the pitch rate or brew a smaller batch if you are concerned.  But I wouldn't even worry about that, at least not stored in my own refrigerator that long.

This is just me, but unless they gave-it-away, I would steer clear of it.
Why take a chance? Just like beer on the store shelf that is past it's pull-date. Stay away!

I would agree, it basically shouldn't cost anything at this point.  If more than a dollar I wouldn't buy it.
