Do I need a stir plate for yeast starter?
You don’t need a stir-plate to make a starter, but they are a good idea. What you do need however, is oxygen in the starter. Simply shaking the starter vessel every couple hours to give it a good swirl will get you results that are almost as good as the stir-plate.
How long does a yeast starter take on a stir plate?
How long should you stir your starter? The rule of thumb is 12–24 hours. Suspended as they are in the swirling solution, your yeast will gobble up the oxygen on offer and use it to reproduce. The swirling motion also discourages the yeast from flocculating, or clumping up and settling to the bottom of the flask.

- Add yeast pack.
- Incubate 24–36 hours at 70 °F (21 °C).
How do you cold crash a yeast starter?
The starter should be completely fermented out within 2-3 days, at which point you can cold crash the starter in your fridge. When you’re ready to pitch your yeast, decant the starter liquid, leaving the yeast slurry at the bottom of flask behind. Swirl the yeast and pitch into your beer.
When should you start a yeast starter?
Make your starter at least 24 hours before you need the yeast. Remove your yeast from the refrigerator. If you’re using a Wyeast Activator, go ahead and smack the pack. It doesn’t need to swell; you just want to release the nutrients in the internal pouch.

What size starter should I make? Many recipes call for a 1L starter, but we actually recommend using at minimum a 2L starter. As a general rule of thumb, the larger the starter, the more yeast growth you’ll achieve. This will allow the yeast the most nutrients and sugar to grow more cells.

Besides brewer`s yeast, homemakers in the 19th Century used specially brewed ferments to make yeast. The basis for most of these ferments was a mash of grain, flour or boiled potatoes. Hops were often included to prevent sourness. Salt-rising bread was made from a starter of milk, cornmeal and, sometimes, potatoes.
What is a yeast stir plate?
Stir plates are used to quickly make healthy yeast starters. Through constant stirring, stir plates introduce oxygen and keep yeast in suspension. This ensures healthy yeast growth and an adequate pitch rate. The best stir plate for homebrewers is the Maelstrom because of its power, durability, and timer functionality.
