So I made and experimental brew in the fall using a lot of Oval-tine and a bunch of other household groceries and once it was done fermenting it smelled terrible. So terrible that I was not even brave enough to taste it so I decided to throw it out. I seem to have forgotten to throw it out and it has been sitting in my basement in a glass carboy with airlock for months and now has mold on top of it. I smelled it this morning and it actually smelled pretty good to me. Should I taste it or get rid of it? The mold scares me a little since I didn’t add anything to the wort except US-05.
Dude!
Taste it.
it’s not going to hurt you and it might be amazing. what does the mold look like?
I’m scared
A) Nothing that grows in beer can kill you
B) Whatever doesn’t kill you makes you stronger
Therefore:
C) Drinking this beer makes you stronger. Go for it!
Ah, but is anything that grows in ovaltine bad for you?
I wonder what the other “household groceries” were? Beets! Nothing beats beets beer!

No beet, but I love beets so I will keep that on the back burner. 
A friend once made a “beetweizen”. You couldn’t really tell there were beets in it.

Rack that beer out from under it and get on with your day.

Tried it. Pretty good and a little tart, like a sour beer. Seems way low on alcohol and I sort of remember being low on the OG I was going for so I am not sure I will keep it.
kinda looks like a pellicle to me.

I also thought it looked like a pellicle.
A friend of mine made a beet beer - smelled like dirt, tasted like dirt but was this psychedelic purple color. It’s become the stuff of local legend now.
But back to the OP… I like sour beers and all, but that picture doesn’t inspire confidence. Looks pretty gnarly!
I think it looks like a pellicle - possibly with some mold growing on top (brown specs?).
Most times the pellicle keeps the mold out - I normally skim off any mold-like specs, but in a carboy I wouldn’t risk stirring it up.
You could rack off - but I would just put an airlock on it and see what it tastes like 8 months or so!
