yeast starter question...

[rsmillie76]

My brother made a 1 L starter last night. He isn't planning on brewing until Monday. Should he refrigerate the flask tomorrow and bring back up to pitching temp on Monday? Or would he be fine leaving it out at room temp until he brews on Monday?

Refrigerate, pour off the excess liquid, swirl and bring up to room temp, pitch.

It would actually be better to toss it in the fridge now if it's done (if it's on a stirplate, it's probably good to go, otherwise wait until tomorrow morning). That way, the yeast will all floc out, and then on monday he can pour off the nasty oxygenated beer on top and just use the yeast cake at the bottom. Definitely warm it back up to pitching temperature slowly though.
