Which one did you get?Personally I just searched ebay until I found a lab grade 100w stir plate-- I have done 2 gallons starters on it without issue, and it creates a lovely vortex; 5l starters are nothing for it.
NB: I did have to get a barbell stir bar for larger starters. The typical center point stir bars got thrown too easily at higher speeds.
Which one did you get?
It is not really important to get a really big vortex going. A constant motion is enough. Even just a relatively small dimple on the surface.
My stirplate can pull a large vortex in a 5 liter but I guess I didnt realize it was going to be a dick measuring contest. I didnt have a 5 liter on hand when I shot that video. Just buy the Maelstrom I guess.Well, that's good, but compare it to time index 1:20 on:
where it shows a far bigger vortex.
I don't think a "dimple" will do it for me. I'm experimenting with doing high gravity starters (to better match the target must) using Hordindal kveik yeast, and if the stir plate doesn't pull a large vortex to get oxygen in there over an extended time period, the krausen simply gets in the way. It turns out that Hordindal needs a lot of oxygen to make its yeast happy (well, at least in my experience so far).
Seeing is believing. I wish there were a good video of the stirstarter XL doing large vortexes, but maybe it can't.
This. Plenty of surface area between liquid and air with just rotation. You only need to move the liquid around to keep diffusing O2 into it.
A thick krausen appears to get in the way. Hornindal is very foamy yeast.
Well, to be fair, the thread topic is "the fastest and most powerful stir plate for a 5L flask". i.e. that's what I'm trying to find, and I've given reasons as to why.My stirplate can pull a large vortex in a 5 liter but I guess I didnt realize it was going to be a dick measuring contest.

Not sure what you mean. I've tried it both ways at small scale.Sorry to come off like a dick, but your reasons are not supported by fact.

I have a video stirring a 3,gallon carboy on this page https://www.brewhardware.com/product_p/noreasterstirplate.htm
Hey Bobby, how did you keep the stir bar on the curved bottom of the carboy? I was always of the understanding that it would have a tendency to throw the bar... Thanks!I have a video stirring a 3,gallon carboy on this page
I use stirstarter with foam control added to keep foam under control. Make 5 liter starters all the time with it
Oddly unprofessional reply for a vendor lolMy stirplate can pull a large vortex in a 5 liter but I guess I didnt realize it was going to be a dick measuring contest. I didnt have a 5 liter on hand when I shot that video. Just buy the Maelstrom I guess.
Seems it's always the same every thread. One side prefers overkill and the others prefer not overkill. Rinse and repeat. CheersI'm ok with it.
I don't know why some folks think macerating a starter is necessary...
Cheers!
Thanks for the warning.I have a Black Maxx. Insert joke here: __________. I am not very satisfied with it. It throws the bar, the bar chatters, sometimes the bar stops spinning and the dial is super finicky. Maybe I'm doing something wrong and someone can throw me some tips/advice. Until then I don't recommend this plate.
Or unlucky!The knob goes all the way to 13
I suppose that's yet another way to skin the cat. Which foam control are you using? I just recently acquired some Fermcap-S.
Hornindal Kveik is far foamier than any other yeast I've tried. Hothead and Voss are also foamy, but not to the same degree.
I generally use the 2-3 settings with a 3 inch stirbar with my 1/5 litre flasks. Not sure what advantage slowing it down slower then the lowest setting would have though? The backlight will turn on for a minute when you press a button without changing the settings. CheersReporting back:
I received the Maelstrom, and it is indeed more powerful than what I had been using previoiusly. A couple of quirks:
1. The display turns completely off after a while. I'd rather it stay lit.
2. It's slowest speed is still pretty fast, and I wish it could go slower. Perhaps the high minimum stir speed is to keep it from stalling? Just a guess.
