I have 5 gallons of a dark ale which just finished fermenting. However over the course of a day, some ugly looking black and grey mold grew on top. There were two nodes and lines coming out from them. And an overall film.
So I scooped the mold off the top.

This summer I'm going to live in an apartment with no air conditioning and open windows. I am going to keep my fermentors in closets with some insulation. However, even in Wisconsin there will be a few days where its 80-90 degrees.
Does anyone have any neat tricks keep the fermenter cool, or...
