The thing is, we cannot know what mold and what possible mycotoxins are there... As I wrote in the other thread, I did extract from moldy cact and drank from a brew made with previously moldy vine, but in the first case I analysed it afterwards and it was clean, and in the second case I cleaned it up and scraped the mold off before brewing.
If you have the mold on the brew itself, thats a bit different. Heat and all of that may kill the fungus, but maybe mycotoxins could still be there? Who knows..
I`d either extract it or I`d toss it, in your case. If I extracted, I`d first remove the mold manually, filter the brew, and then extract. I`d try to run some tests if possible, or in the worse case, I`d only consume the extract by doing allergy tests with small amounts and raising it gradually in next sessions.
Hopefully its not a very concentrated/large brew....
