I just racked to second and saved approximately 4 capped bottles of slurry (Safale S-04 SG 1.057, FG 1.017) which I do not plan to wash. I am planning to re-pitch some in about a week but the others may not be used for a while. The questions are these: Do I need to refrigerate them? If not, at what temp should I keep them? If so, do I need to do anything to re-energize the yeast in the slurry before I re-pitch? If so, what do I need to do and when do I need to do it?
