I have a 1.052 saison with WY3711that I will be cold crashing in the primary for about 3 days then let warm to bottling bottling temp- 68F. I know at cold temps the yeast go dormant but will going from warm to CC back to warm affect the yeast health for repitching?
You can repitch the yeast cake at the required dosage as long as you pitch at the proper temp and ideally within a few days of harvesting the cake. I have heard of some brewers repitching within a week but if longer than that I recommend making a starter.
