The Maelstrom Stir Plate has a five-speed control and can be used on anything from a 1000ml erlenmeyer flask up to a 5 US gallon (18.9 litre) carboy. Other features that make the Maelstrom Stir Plate an essential piece of kit are that it can run indefinitely and it can be programmed up to 48 hours ahead of stir time. You can even see the powerful rare earth magnets rotating while it's operating!

This is, we’re confident in saying, the most powerful and versatile homebrew stir plate ever made.

Note: The instructions say to set a time period for the plate to run. If you want the plate to run continuously, leave the time set to zero.

Includes a UK power adapter.

Doesn’t include an erlenmeyer flask.

Cultivating yeast from past batches can save the dedicated brewer a lot of money in the long term, and harvesting sediment from interesting bottles can give access to otherwise unheard-of strains. If you’re a yeast geek, then this industrial-grade programmable stir plate designed for yeast starters is a must.

Powerful and good value
Review by
I have been using the Maelstrom for a couple of months now for stirring my yeast starters. It is a powerful and almost silent unit that easily copes with my 2L starters and I am sure will manage much larger volumes. I have used a variety of stir bars including a pretty heavy one and it runs smoothly with them all. The buttons are all fully sealed making the unit splash proof and easy to clean. I mostly just use it on continuous mode but the timing function could be useful if you wanted the stir plate to stop at a certain time without your input, for example to start crashing the starter. Recommended - all the features of a laboratory grade stir plate at a good price point.
