Maelstrom® Stir Plate
The first industrial-grade programmable 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 starters in a 1000ml erlenmeyer flask, all the way up to a 5-gallon carboy.
Command a massive 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. 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.

Replaced a home made one. Works great.
first beer was a light lager 10 gallon batch. This thing almost doubled the cell content according to beersmith and it really showed in the fermentation. Super quick 7 day primary fermentation! That’s the best I’ve ever done with a lager. The maelstrom handled the 4000ml starter with ease. Highly recommended.
They are a great place to do business with. Thanks
I bought this mainly for 1L or 2L starters to focus my attention a doing high gravity beers. Although I picked it up when NB had a smoking sale it's still a must have for serious brewers IMHO. Isn't it really all about the yeast?!
This thing worked great right out of the box. Very easy to set up. So far I've done 2 two liter starters each at 12-16 hr stirring and the timer worked great. I only wished it came with additional stir bars. Would've been nice!
Needed a large starter for a 31 gallon batch so I purchased the Maelstrom after reading many reviews on similar products. I boiled up 3.5 gallons, pitched yeast and started the stir plate, came back to check after 1 and 2 days. The product is very simple in its construction, but worth the money so far. There is 1 thing that bothers me about the product after 1 use, and that is that you cannot just drop the included stir bar into the container and then turn it on, or at least that was my experience. I attempted that with a couple of different tests and containers. Fortunately that was an easy fix, as on a hunch after reading some reviews I had already purchased a package of 2” stir bars which have a small band that runs around them in the middle of the bar to hold them off the surface of the container slightly. Dropped the new bars into the wort and turned it on, covered and walked away.
