Description 

This basic stir plate will dramatically increase the rate of yeast growth in your yeast starter flask. Just put the included magnetic stir bar into the flask, and place it on the plate. Spinning magnets in the plate cause the stir bar to rotate, agitating the yeast starter.

This unit has a 12 volt stir motor, which is controlled by a precision voltage regulator for easy speed adjustment. The RPMs of the drive motor are limited, so the motor will not “throw” the stir bar (unless you turn it up too high or move the starter once it has started), yet it provides enough to get a good vortex going. A low voltage, plug-in wall transformer provides power to the unit. The black plastic case dimensions are 6" x 4" x 2", large enough to accommodate a 2000ml flask (1000ml flask shown above). A Teflon coated 1"stir bar is included (longer bars are not recommended). A “keeper” magnet is also supplied to lock the stir bar in place while the yeast is pitched, so the stir bar won’t end up in your fermenter.

Unlike much more expensive laboratory units, this model is not designed to be used with corrosive chemicals, in wet areas, or with hot items, but it works just fine with yeast.

I'm Glad I Finally Got This
I've been a home brewer for over 20 years, and I think it's safe to say that I didn't "need" a yeast starter kit, but I'm glad I got it.  I've always been able to get fermentation started, but sometimes it took a couple of days with a heating pad.  I prepared the starter the day before and dumped it, I mean pitched it, in the wort the next day.  Fermentation was going real good within 24 hours.  It took me about an hour to prepare the starter, 20 minutes to prepare it and at least 40 to wait for it to cool.  So, an hour the day before, potentially saved me up to a couple of days.  The stirrer works great, and I'm glad I paid a little extra for the starter kit, because it had everything I needed. Don't forget to use the "keeper" when you pitch the yeast.  I forgot the first time and the stirrer went into the fermenter. Rookie mistake.

Does the job well
I've done three yeast starters with this and it's doing a great job. Quiet, lightweight, easy to use.

Great Stir Starter
I saw this product in Zymurgy.  I have made starters, but only by shaking them.  This is much simpler.  The product was easy to find on the Williams website, and arrived quickly. No complaints.

Would have wanted to know
The item seems like it could break apart with a fall from any height. I wish I would have been able to read that a growler doesn't work with this Item. Stirstarter Is simple to use and worked out the box. William's Brewing customer service comes through, which is why I prefer to buy here.

William's Brewing Responds:  Thanks!

Works with a 5L flask
I have 2 of these now and my older one (about a year old) still works great! I use these with 5L flasks without any problems. You can't crank it up all the way or it will throw the stirbar but it still gets a decent vortex going at about 3/4 speed. Virtually silent operation.
