How aggressive should the vortex be on my stir plate?

metasyntactic · Feb 24, 2013

Should I just ramp it up and let it hit the stir bar, and if not, how vigorous should it be?

Not very vigorous at all just enough to keep the yeast in suspension.

Too much can generate too much heat, just enough to keep the yeast suspended and pull some O2 in

It is a common error to want a big vortex, the commercials all show them, after all!

Just a small dimple on the top is all you need.

I let it suck in some air. I want to see small bubbles of air being swirled around the starter.
