not necessarily true - very possible that the starter ferments out completely by then
the main issue IMO is not having enough time to chill and decant the spent wort but dep on size of the starter and style of beer it may not be an issue at all to pitch the whole thing
I stand corrected. I guess that a possibility and worst case scenario is that you pitch a smaller amount.t of yeast. Also consider though that the yeast, depending on the strain may not have time to fully floculate and if decanting first, may result in less yeast. Especially not having time to cold crash.
I never allow more that 2 or 3 days for a starter. I think I've heard Jamil say that there is little growth beyond 18 to 24 hours if on a stir plate. You may just need a little more time to decant. I like to make small enough starters (if I can) to just pitch the whole thing after 24 hours on the stir plate.
