Product details

The first industrial-grade programmable magnetic stir plate designed specifically for yeast starters.

Now includes a Stir Bar Removal Tool!

Breed a Herculean army of yeast for brewing bigger beers than ever before. Powerful rare earth magnets churn through any size starter and never throw a stir bar. Five-speed control adapts to sizes from minute to mammoth, for yeast starters in a 1000ml erlenmeyer flask, all the way up to a 5-gallon carboy.

Command a massive yeast starter while you're at work or over the weekend. Let it run indefinitely, or program up to 48 hours of stir time. Schedule it to settle out yeast just in time to come home and brew.

Watch Maelstrom® surge through starter wort creating a vortex like no other. The transparent body shows the magnets whipping through rotation. Plus, the seamless surface makes for easy cleaning.

Easy to use with an intuitive interface, the Maelstrom® sets the new standard as the most powerful and versatile homebrewing stir plate ever created for the home brewer.

Be sure to check out our Yeast Starter Kits in 1000 ml and 2000 ml sizes.

Have to hold flask 6 inches above to have it work properly when I start it, otherwise it won’t stir like it should.

The best stir plate

having used a couple of other stir plates, this one blows the rest out of the water. It quickly pulls the stir bar into place when you put it on the plate, and has a number of stepped speeds so you can find the right rate of stirring. The construction is solid, and works well on starters I've made up to 4L.

Great stir plate

Only used it twice so can't speak to longevity, but it worked great. Vigorous whirlpool and no obtrusive noises. Magnetic stirrer never slipped off either. It also looks like a strong build. I bought this product for longevity so only time will tell.

Good stir plate but a little under-built

The unit works well and I like the large platform and timer feature. However the plastic bracket that holds the stirrer mechanism on the first one I received was broken. NB promptly shipped a replacement at no charge (and did not require return of the original unit) but a **** had vibrated out on this unit and a second was loose. I had to disassemble the unit to find and replace the **** and now the unit works as advertised. The problems probably evolved in shipping and I think since the machine will be in a stationary location there may no further issues but I’ll keep an eye on the screws to make sure they don’t loosen. Screws holding the bracket in place could be more robust.

Does the job well enough. I'm not sure if they're all like this, but mine at least you have to hold the flask off the top as you start it and kind of let it connect to the drive magnets at a distance and start spinning before you set the flask down. Trying to start it with the flask sitting already and the stir bar just kind of twitches and it shuts down after a bit. So kind of tricky to get going, but I've made a couple different starters with it now and it sure beats the swirl whenever you can method. Hope this helps someone.
