I repitched 3724 slurry with a starter on Sunday for a cherry saison and it took off within a few hours. With this strain, subsequent pitches are reportedly more vigorous and less likely to suffer the infamous 3724 stall.....we'll see.
Over time this approach is not only easier but probably cost effective. The SNSYS process is pretty easy(shaken not stirred yeast starter) and I tend to use this because I don' t brew often enough, as I said earlier, to do a straight repitch. Some of my saved yeast is getting a little long in the tooth. I keep asking my wife to avoid stuffing things into the 4th shelf down in the fridge!
