What is this yeast doing???

[Rambleon]

A little over a week ago I procured some yeast (1056) from a local brewery. I made a 2000ml starter that night with a decent chunk of the slurry and pitched 1500ml of the starter into a 1.065 IPA the following night. I poured the remaining 500ml's of the starter into a sanitized mason jar and through it in the fridge for later use (I love saving $!).

So, here we are a week later. It's been sitting in the fridge at 35-ish degrees the whole time and when I looked at it this morning it had this massive krausen (relatively speaking). When I popped the lid off to relieve pressure I nearly put my eye out with a yeast shower! I was under the impression that as soon as the yeast felt the fridge temps they would fall dormant. This has always been my experience in the past. It's slower with lager strains but it always eventually happens. What gives???

The chico strain chugs along in conditions you wouldn't expect it to. It doesn't taste great under lots of stress, but it keeps working. It's a workhorse. 35° though... that's impressive. Is that the first time you've harvested this lot, or have you serial pitched it a few times?

The brewers said this was the 3rd pitch of this strain. It was my first so that makes it 4 I suppose.

It gets more and more attenuative for about 7 generations, so you have some hearty yeasties there. Expect really good attenuation when you get the next batch going!

1056 is already a pretty angry yeast. My only blow off I have ever had was with 1056. But, it may take a couple of days to go dormant. The yeast also creates heat during ferment. So maybe the temp has not fully dropped? I would leave it in and see what it looks like in two days.
