It won't happen instantaneously, but they will start to grow as quickly as they can when the conditions are right for growth.I've always thought that pitching a start that is still "active" is the best way to go and that brewers let the starter finish so they don't have the bland starter wort/beer diluting the batch...Tom, is this the best method for yeast health and harvesting the yeast from the target batch? Is the lag time important as the yeast go into growth phase, or will they just jump back to growth phase when they are introduced back into the target wort?
For harvesting, if you're using a top cropping yeast then top crop. For other yeasts, just get it after it flocculates and the yeast will be plenty healthy. Even from a high gravity wort when the yeast are a little beat up, you can baby them with low OG wort and nutrients and they'll generally recover pretty well.
