Cellar Science Yeast Experiences?

[JIm S.]

Hope to solicit experiences using Cellar Science yeast?

I've been at or within 1-2 final gravity (FG) points of recipe specification over my last couple dozen batches using my most recent brewing system.

That is until my last two batches using Cellar Science yeast for the first time where fermentation stopped significantly high of recipe specification:
- FG +10 points, Cali yeast, Blonde Ale
- FG + 8 points, English yeast, Stout

All processes and ingredient sourcing/handling have been the same. Recipes previously brewed without issue using Fermentis yeasts.

Coincidence or are others experiencing Cellar Science issues?

Thanks!

I dont have any direct experience with Cellar science, but you could have gotten some older dry yeast?

They may also just be slightly different yeast then what you were using before?

It could have also gotten damaged in shipping if it was very hot out or something?

I use Apex yeast and it is extremely reliable and cheap.

I've used it once or twice but I can't see what recipe I used it in on first glance. I don't remember having trouble with it.

Well cellar science and apex are not yeast labs just repackaged from bricks of fermentis and others
It's a more.beer product
I've used many of them with good results
Can't say why you get a 10pt difference

I dont think apex is repackaged(it could be, but i dont think it is). They say that it is produced in Sweden. AEB is produced in Italy. Fermentis is in belgium?

at the end of the day, the yeast is very good and is very consistent and cheap.

10pt could be a bad thermometer during mash or knock, old yeast, lots of variables.

I stand corrected
Doesn't matter they are both good yeast alternatives
I've used both

I use 3 bricks of celliar science yest, I'm happy with all

Thanks for the information.

Interesting it might be repackaged Fermentis (other?).

The above CS yeast was used within 6 months of manufacture and refrigerated after purchase. Yeast was rehydrated before pitching per CS and my normal sanitary protocol. I do have calibration and secondary thermometer checked fermentation and all-in-one brew system temperature control.

Maybe the product was affected during shipment to the homebrew store. I'll inquiry with them.

Not fully ready to give up on Cellar Science (yet) but next batches will use Fermentis for reality check.
Thank you!
