4.8 / 5.024 ReviewsIt is a TANKJust upgraded my 3 "project kit" stirstarters to 3 of these Maelstrom's. I typically do 15 gallon batches of Pilsner - so 5 liter starters are normal for me. These stir plates remove the risk of the flask falling over. No longer do I have to worry about the stir bar being thrown or fighting to get it centered. On speed setting 2 it will easily vortex a full 5L starter. Setting 3 and above are a bit more than you need and get a bit louder than I want - gotta keep the Wife content while making yeast babies! Product literature states it is for a 1L, 2L or 5L flask. There is no reference to the device being engineered to withstand the weight of a 5 gallon glass carboy filled...February 13, 2016Love itWorks like a charm, well made, sturdy, buy it you'll be happyJanuary 10, 2017Purchased
11 months agoOh Yeah!This thing kicks butt (instead of kicking the stir bar) with carboy sized starters. Easily centers the bar through the thick glass of carboy base. I also like the fact that the surface is pretty much waterproof (not for submersion) and spills / splashes /drooling are easily cleaned off.May 15, 2017Purchased

Very quite and easy to use.March 1, 2016Great customer service!I really appreciate the fantastic customer service that we received- the item didn't work when we got it but was resolved super quickly!! Thank you!January 12, 2016Stir it upAfter brewing approximately 20 high gravity beers this is my first batch that I made a starter. The Maelstrom stir plate was the perfect tool for the job. It made a huge difference, taking a good beer and making it a great beer. I highly recommend getting some Fast Pitch to go along with the Maelstrom, to make the easiest and best starter you will ever make.March 5, 2016Built like a tankWorks great with a 1/2L, 1L, and 2L (haven't tried bigger) flask. The timer is a useful addition. Why waste time brewing with an insufficient pitch.March 9, 2016Very Nice!Smooth, quiet and plenty big enough for 5000 ml starters!April 24, 2017Purchased
6 months agoGrains, Yeast & HopsIt is nice to be able to go to Midwest Supplies to find all of the ingrediances necessary to brew the beer I want. Midwest Supplies had everything I need to brew Nut Brown Ale and a Cocoa Mole.July 30, 2016
- Customer Q&A
Browse 2 questions Browse 2 questions and 6 answersWhat is the RPM for each of the 5 speed settings on your Maelstrom Stir plate?BEST ANSWER: While I haven't specifically tested this, I'm going to assume that the RPMs of each speed would vary based on the size of the stir bar you are using. I've used a .75" stir bar for 1 liter and at a 5, the speed was WAY too fast. On the other hand, I've used a 1.5" stir bar in a 3 liter starter and had to keep it at a 4 to maintain a slight dimple in the starter. I hope that helps but I don't have the specific RPMs of the actual magnets.What is the most sanitary way to get the magnet out of the yeast before pitching?BEST ANSWER: I pitch yeast starter through a sanitized funnel with mesh filter that captures the stir magnet so it doesn't enter fermentation vessel.
