What is a yeast stir plate?

A stir plate is a device used to create a constant stirring motion in a yeast starter. Constant stirring increases yeast growth and creates healthier yeast for fermentation of your wort.

Why buy a StirStarter stir plate?

Laboratory grade stir plates cost hundreds of dollars and are designed to stir liquids of all kinds, some hazardous. The StirStarter is made just for yeast, so unnecessary and expensive features can be eliminated. The StirStarter comes with a lifetime guarantee. If it fails for any reason, simply return it for a free repair or replacement. This is the only stir plate we carry, just because anything more is unnecessary for brewing. We've had one of these running in the store here for years with no problems at all!

Why do I even need to make a starter?

Most home brewers don't pitch enough healthy yeast when they brew. Yeast starters are especially important if you are brewing lagers or "big" beers.

What size beaker or flask should I use?

The StirStarter works best with a 1 to 2 liter Erlenmeyer flask. Using a growler or other vessel with a convex bottom is not recommended. The stir bar will not spin without throwing the bar to the side in this type of vessel.

How fast do I need to sir my starters?

It isn't necessary to develop a deep vortex in the liquid to get a good stirring motion. The goal is to keep the yeast in suspension and in contact with the air. The deep vortex looks cool, but it's not needed for good yeast growth.

Do I need to change the way I prepare my starters?

No, you don't need to change what you're doing. Prepare your starter as you normally do and simply put the starter on the stir plate, letting it stir overnight. When you brew the next day, your starter will be ready to go!

  1. Great product great price

    Posted by Randy on 12th Jan 2015

    This is a great product with a full lifetime guarantee at an unbeatable price. How can you go wrong? On top of all that the stir bar and keeper magnet are included.

  2. fine for 1 or 1.5 litter cultures in a 2 litter flask

    Posted by Frank Hruby on 30th Jul 2014

    not user serviceable. Not moisture resistant. If your culture overflows the starter plate will short out.
    burnt out for me driving a 3 litter culture in a 5 litter flask. too much work for the litte fan motor.

  3. Great Deal

    Posted by Komocabo on 30th Dec 2013

    I got this for Christmas and it is great. The quality seems right for the price. The only complaint I have is that I got the 2L flask (which is great), but the base of the stir-plate is much smaller than the base of the flask, so there was a little balancing act that I had to do. If I were to change anything in the design, it would simply be to make the casing large enough. I want to get a 5L flask, but am very nervous that it would be too big for the stir-plate.

  4. Love my StirStarter

    Use this for every beer I make. Terrific price for flask, too! Have used it to culture bells yeast from bottles with success every time.

  5. great product and price

    I have been researching new and used stir plates and was considering building my own. This one works great and the price is very reasonable.
