Pressure Kills Yeast?
« on: December 14, 2012, 06:45:24 am »
I saved some WLP037 slurry for an Irish Ale I was planning to make next week.  I forgot to release the pressure and when I checked on it yesterday the container was pretty swelled.  I released the pressure and put it back.  It was saved from two batches of Brown Ale so there was a good amount of yeast in there. 

Did I just kill them all by death by pressure?

Your yeast should be fine.  Make a starter to rouse it and you'll be good to go. 

As far as I know (which isn't much) the yeast shouldn't be able to produce enough pressure actually kill themselves.

Where the heck are we going?  And what's with this hand basket?

Making a starter or at least taking a sample and making a small starter to check the viability of the yeast is a good idea.

Pressure can kill yeast, but not the pressures that brewers encounter.
