Yeast Stir Plates For Home Brewers
Here's a brewing tool that will make your good beers better. Many home brewers don't pitch nearly enough yeast. This stir plate helps you culture higher cell counts of healthy yeast for quicker fermentations, lower risk of infections and better tasting beer. All this in less time than it takes to make a conventional yeast starter.
This unit has two powerful NdFeB button magnets in the 12 VDC 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, 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 accomodate a 2000 mL flask as shown. A Teflon coated 1" x 5/16" stir bar is included. 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!
