Ends Today: Maelstrom Stir Plate – Industrial Grade, 5 Gallon Capable! – $127.99, Save 20%

maelstrom stir plate

Maelstrom Stir Plate

The first industrial-grade programmable magnetic stir plate designed specifically for yeast starters.

Breed a Herculean army of yeast for brewing bigger beers than ever before. Powerful rare earth magnets churn through any size starter and never throw a stir bar. Five-speed control adapts to sizes from minute to mammoth, for yeast starters in a 1000ml Erlenmeyer flask, all the way up to a 5-gallon carboy.

Command a massive yeast starter while you’re at work or over the weekend. Let it run indefinitely, or program up to 48 hours of stir time. Schedule it to settle out yeast just in time to come home and brew.

Watch Maelstrom® surge through starter wort creating a vortex like no other. The transparent body shows the magnets whipping through rotation. Plus, the seamless surface makes for easy cleaning.

Easy to use with an intuitive interface, the Maelstrom® sets the new standard as the most powerful and versatile homebrewing stir plate ever created for the home brewer.

Features:

  • Stir Bar Removal Tool
  • Includes a 50mm stir bar
  • Five distinct speeds, from 480-1440 RPM, to accommodate yeast starters up to 5 gallons
  • Scheduling function for up to 48 hours
  • Seamless surface for easy cleaning & maintenance
  • Powerful magnets will never throw a stir bar
  • Translucent body lets you watch the magnets in rotation
  • Standard 12V Power Adapter
  • Large 8″ W & x 8 ½” L stirring platform

 

Why a Stir Plate? The constant motion of a stir plate integrates oxygen, puts yeast in constant contact with nutrients, relieves built up CO2 and generally helps yeast to grow more rapidly.  That also means smaller starters.

StirStarter Magnetic Yeast Starter Plate – $39.99 w/coupon

The Stirstarter Yeast Stir Plate

The Stirstarter Yeast Stir Plate

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 (110v), 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 2000 mL flask . A Teflon coated 1″ x 5/16″ stir bar is included

(2″ stir bars are too long for this device, while we have had success using the 2″ bar, it will be “thrown” from the magnet when the motor is at high speeds, “why would you turn your stir plate to higher speeds?” you ask. We aren’t sure, but the coffee at McDonald’s is hot whether the word “HOT” is printed on the cup or not)

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!

Why a Stir Plate? The constant motion of a stir plate integrates oxygen, puts yeast in constant contact with nutrients, relieves built up CO2 and generally helps yeast to grow more rapidly.  That also means smaller starters.

I’ve used the StirStarter for years and it has worked very well for me.  I can wholeheartedly recommend it to you.  Check out our in depth Hands on Review!

This is selling for $49.99.

Erlenmeyer Flasks on Electric Stovetop? Yeast Starters Using the Double Boiler Method

Yeast Starters on Electric Stovetops Using the Double Boiler Method

It is important for your safety to heat water in the flask with a heat source that distributes heat evenly. Morebeer! recommends using the “double boiler method.” This process involves using a boiling water bath on the outside of the flask to heat up the water inside the flask. All you need is a kettle 3 gallons or larger. This process is much safer and efficient. If the flask should break or boil over, your kettle will be there to collect the contents, thus keeping your stove clean and keeping you safe. – via MoreBeer

Beakers vs Erlenmeyer Flasks for yeast starters?  Beakers have a few advantages compared to Erlenmeyer flasks. They’re more space efficient, easier to clean and they seem to also generally have a price advantage. Erlenmeyer flasks have the advantage of a small opening that can take a stopper and airlock. An easy solution for beaker is a piece of sanitized foil and a rubber band.

  • Use along with a compatible Erlenmeyer Flask and Stir Plate to do Stir Plate Yeast Starters.
  • Why a Stir Plate? The constant motion of a stir plate integrates oxygen, puts yeast in constant contact with nutrients, relieves built up CO2 and generally helps yeast to grow more rapidly.  That also means smaller starters.
  • Why get 10?  Generally, you’re going to save money buying in bulk.  Having these on hand allows you to do multiple starters at once and… you’ll have spares if you mistakenly dump your stir bar into your fermenter.
