Typical digital BS. When it works it is fine. when it does not, it is landfill.

Amazing Machine!

This was my first attempt with a yeast starter and using the Maelstrom Stir Plate. I used a liquid yeast and one Canned Wort and in 24 hours I had a starter from hell! I poured the starter into my cooled wort and fermentation started within an hour. If only I had known of this benefit sooner. This will be my process going forward. Well worth the investment!

Maelstrom Stir Plate

I am always amazed when I read the number of good reviews for this plate. I own two Northern Brewers stir plates. One of their originals which which was not very expensive but simply couldn't handle starters any larger than 1.0L. Bought one of the Maelstrom plates expecting a powerful stir plate, as they advertise it as such. It won't even start itself with nothing on it. I have to use a small steel tool to get it started. Half the time when I put a 1.5L flask on it, it stops. Start it by hand again, sit the flask back and hope it stays running. Forget any speed adjustment or creating a whirlpool, just feel lucky if it keeps the stir bar moving. Envious of you folks that have one which actually works. Northern Brewer not good at standing behind their products. I could comment on their Steelhead pump but enough for now.

Nice Stir Plate!

This stir plate is really nice. I built one years ago out of a hard drive magnet, computer cooling fan and a cigar box. This was a major upgrade. I especially like the count down timer function. The only reason I gave 4 of 5 stars is that the transformer/power cord that mine came with was complete garbage. It semi-worked one time and then it was dead. Thankfully the stir plate uses a standard 12v 1000ma wall wort and I had a drawer full of them.
Besides providing a better quality power adapter the only upgrade I think this bad boy needs is some internal bling lighting. Highly recommend!!
