How long should a yeast starter stay 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.
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.
