I'm using my new stir plate finally with some washed yeast from last September. I think the yeast froze a bit in the fridge and I'm not seeing any krausen (or the little ring showing it fermented) 10 hours after pitching. I'm wondering if the stir plate would just suck the krausen back down or would you see it?

My issue is that I'm placing my order in today and I wanted to see if this yeast is good or if I need to buy more yeast.

Advice?

I only keep my starters on the plate for 12-18 hours. Out of 6 starters so far, I've only had krausen on my last, a kolsch. You can definitely tell by the color though if the yeast are growing. IMO, if you think you froze them I'd get some more.

I usually don't see any, but I do see the starter viscosity change and it does get thicker after a number of hours and you'll see less of a vortex as a result.

Well, I believe that I may have some growth because when I turn the stir plate off, quite a bit of white yeast settles to the bottom. Also, it just smells SUPER yeasty. I'd really rather not spend $6 dollars, but I guess it's better safe than sorry.

My last starter was with WLP400 and even on the stir plate it overflowed the airlock with foam. I've had others that fermented overnight and it looked like nothing happened.

Measure the gravity and you'll know for sure.

Stir plate kills the krausen. If you get any, it will go up and down in 30 minutes. Look for a color change.

Well that's my experience with typical starters, I won't ever see it ferment, but I'll see a ring.

I'm going to take a gravity sample and I'll get back to you.

My starters always get a creamy color after the yeast blooms.

you will still see some bubbles at the top/side if it's fermenting. sounds like old/dead yeast. September is a long time for washed yeast to survive--I have had this issue before.

During the very active part of the starter's fermentation, I see a huge amount of bubbles. Sometimes a krauesen, sometimes not. The aforementioned telltale ring will be there if you had any krauesen.
