Yeast Starter

[Brewer #58898]

Am planning to use a yeast starter for the first time and have watched a couple of YouTube videos on how to do this. I plan to use an electric stir plate and was wondering how long the Erlenmeyer beaker needs to remain on the stir plate? I plan to make the starter the day prior to brewing. Should the beaker remain on the stir plate for the full 24 hours? Or just long enough to get properly oxygenated - say an hour or two? Thanks, Hugh

its entirely up to you, an hour or 2 is just waking up the yeast and getting them ready to eat and just starting to reproducing more yest, if you want to double your yeast cell count I would do a 24 hour or at least 12. When the foam in the center is gone and no foam on top and the whole flask has changed to an ivory tint, its done

but again if your in a hurry and don't prepare a day head and you don't need more yeast, an hour or 2 is fine
