Hi all. I am brewing a Belgian Cherry from Zymergy Jul/Aug 15. I have racked the beer to a secondary on top of the cherry purée. It has been a week and the yeast has made its way about 1/3 of the way into the layer of purée. My question is, should I very gently stir up the purée on the bottom to allow the yeast to reach it all or will it happen naturally?
