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.
