I'm about to brew a lager, and then plan on fining with gelatin. It will lager at 34F, and then have a diacetyl rest for 3 days at 60F, prior to bottling. Would you recommend fining with gelatin before the diacetyl rest, during the lagering, or dropping the temp again after the diacetyl rest to do the fining? Also, would anyone recommend adding a bit of yeast prior to bottling after gelatin fining?
