Ok, so my Roselare flanders was going great, it is about 4-5 months into its aging and was forming a crusty white pellicle on top. We had a heat wave here and my attic got up in the 100s for a couple days and now the pellicle has these big black spots that kinda look like tar taking over the top of the beer. The spots are pretty big, a couple inches across and flat.
Anyone experience this before? Know what this is?
Is this a mold? should I rack the beer from under it?
Any help would be appreciated.
