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.

Nice design and execution all around, the only shortcoming to me is that the lowest speed isn't that low, and the highest isn't that high: it's a fairly tight cluster of speeds. Sometimes even at the lowest setting the stir bar gets knocked loose by centripetal force. Oh, and a Wi-Fi upgrade in the future would be great!
Works, but works better with an egg-shaped stir bar.
Vigorous vortex in 3 and 4L flasks, even on low speed.
Works really well, but test it out with water a few times beforehand to time the placement of the beaker and stir bar on the plate to avoid the stirrer being magnetically locked at the bottom. I read a few prior reviews that suggested ways to time the placement of the stirrer and beaker on the plate to make sure it spins properly. Follow that and you should not have any issues.
I reviewed all the stirplates I could find on the market and compared that with simply buying an oxygenation tank/tube to feed the yeast directly. For longterm cost and control, I opted for the Marlstrom because it had the best reviews regarding ease of use, durability, versatility, and warranty. Ive used a 2000ml erlenmeyer flask and 6 gallon glass carboy (with with 1.5 gal. of liquid) centering the magnet on the bottom and then on the plate slowly increasing the speed until it created a beautiful whirlpool all the way down. The programmable features are a must for anyone working with highly active yeast that needs time to grow before pitching.
