Same here, I use it for my last batch of wheat beer, I had to build it up with a starter. Looked like snow flakes. I got a video if anyone is interested of the yeast dropping in the sight glass while in the fermentor.

Thanks for posting this Kal.
I've been brewing for years, own all sorts of equipment, but the one thing I never picked up was a stir plate. Happy yeast=happy beer, so maybe its time to bite the stir bar. Would it work with a 5000ml flask?

Hey Kal, I picked up the same setup and so far with the 2000ml flask, it works great. Thank you for the tip!

How high of an OG do you think you can pull off with just one starter in a 5000 ml flask? I'm wondering as my next beer up is a 1.109 OG Belgian Dark Strong (Denny Conn's Batch 400). Based on some websites, it's suggesting I'll need to step it up at least once, if not twice. That was based on a calculator at Brewersfriend.com that suggested I would need between 1 and 1.25 billion cells for 10.25 gallons of 1.109 wort. I'm all ears if I do not need to mess around with steps.

These things affect how many yeast cells you need:
- Fermentation temp / yeast strain (Lagers typically need x2 as many cells as ales)
- Gravity
- Batch size

You're off by a factor of 1000. You need about 1000-1250 billion cells for that. Assuming it's an ale yeast (which I'm pretty sure it would be).
Assuming the yeast was made today (not likely) you'll start with about 100B cells in one pack. A 5L starter of 1.036 strength would get you to 819M cells. Bump it up slightly to 1.040 and you'd have about 900B cells. Still a bit short. You don't want to go much above 1.040 for the starter as it stresses the yeast and you'd need about a 1.058 starter for this guy assuming very fresh yeast (unlikely) and a good funnel during the starter to maximize growth.
I'd use a 5L starter at 1.040, put it in the fridge overnight, decant, and then grow again with a smaller ~4L starter. It's a massive beer. So there are still times you need to step up! At least it's not 4-5 times. Brewing 5 gallon batches would be single step however.

I guess being an actuary hasn't really translated into the brewing world. In my head to was thinking 1 trillion, but it definitely didn't translate.
Thanks for the confirmation on the stepped starter. I have some starter wort in the pressure cooker right now getting ready for this beer.

I've placed the stir plate and the support stand in my Amazon wish list. I noticed the stir bar listed has the ring around it in the middle. My current stir plate (purchased years ago from someone who was making them and selling them online) has trouble with a stir bar with the ring in the middle and it generally throws the stir bar. Have you experience any problems with this? I don't get anywhere near the vortex your videos show. I know that it only needs a little vortex, but it has a hard time pushing a 3-4L starting in my 5000L flask.

Ive made several stir plates and not all stir bars are the same, you really have to match one brand up with your stir plate,too much magnaticity is just as bad as not enough with some stir bars

I think if you buy a good stir plate it's less of an issue. I have 3-4 sizes of stir bars from various manufacturers and they all work well for me on this stir plate.
Making your own stir plate can be really easy but it's another one of those instances where I had heard enough times from brewers about issues getting them to spin the stir bar reliably that I simply bought one that was proven to be reliable from a company that's likely sold tens of thousands.

I bought this stir plate and I'm using it right now for the first time. It came with 2 stir bars but I'm not using them since I already had some. The first stir bar I used was one with a ring on it and it kept throwing that off to the side. The other one I tried had no ring and worked fine. So not all stir bars work. I will say that this seems to be a very well made stir plate and I'm happy with the purchase. It turns a lot faster then my home made one from a computer fan and magnet from a hard drive.

I'll check the flask when I'm done with the starter to see if it has that hump. Yea this stir plate is a beast

It is the Karter Scientific 2L flask from Amazon that you linked to above. The bottom looks pretty flat to me so must be the stir bar.
