Hi
I read a lot about the improve of using magnetic plate.
Jamil said that he wins by 40% compared to inttermitent shaking. But as the impact on growth rate or decrease in comparison to other methods, example: simple starter or aireation continuous.
I can not find that information on the web. I read Wyest page but only said about to use stir plate or not use in his calculator (I think the other posibility is to use air pump or shaking, but I don´t know),

I haven’t done yeast starter yet but plan to in the next week. I don’t have a stir plate and can’t imagine shaking the wort in the beaker will do any decent oxygenation. My plan is to put the cooled work into a sanitized 1 gallon plastic water bottle, cap it, then shake vigorously before pouring into the beaker. I hope this will give adequate aeration.
Yep, that should work fine. A stir plate would be nice to have but don’t let a lack of one stop you from making a starter. The basics for a starter are a kitchen pot to boil in, a little bit of DME, some sanitizer, and a one gallon plastic jug. Occasionally shaking or swirling the starter while it’s going will help as well.
