You'll be fine. The slurry will still have the glycerine mixed in for when you freeze them. Mine always settle out in the freezer.

I've had my starter going for 48 hours now (forgot about it last night). When is the best time to crash cool?

how long would these last if stored in a 35F keg fridge instead? half as long as if frozen? and what are some average storage terms you guys get in the freezer?

I crash cool them the night before brewing usually. A starter will normally finish in 24 hours.

Frozen I've been getting a year or more out of stored yeast. For the fridge you shouldn't use glycerin and instead just follow the yeast washing procedures and store in the mason jars. Look into the yeast washing thread for the storage time for those.

What about baby food jars? I mean the price is right and I have plenty of those.

I am sure it can stand up to autoclave temps.
So, why not save the cash for grain?

why not just save one bottle of each beer you make, and culture the yeast from that whenever you want to use that yeast strain again.

While that is certainly one way to do it, if your planning ahead you can use a sanitized funnel and put a cup of yeast slurry into a beer bottle as well. I know at least one guy locally that does that.

I'm not sure if the lid (specifically the lining in the lid) will take autoclaving. You might also use a empty clean beer bottle, they are not hard to find.

They are a bit big for freezing yeast. You want to preserve a small sample when freezing.

But baby food jars are excellent for preserving small quantities of yeast in the fridge, however. And yes, I believe you could autoclave the lids.
