Sale price$174.99


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

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.

Bought this to replace my previous stir plate when I had trouble getting contact when trying to make a 3L starter with my 5L Erlenmeyer flask. No problem with the Maelstrom Stir Plate! Rips through your starter like a warm knife to butter! Could only use #1 setting when using for my 2L flask! Great product!
