Default mold in malt extract

cooking a batch today. Opened my malt extract after steeping my barley and there appears to be mold on top of my malt extract. I stopped here and I am wondering whether to abort batch or skim off the mold and proceed.

Skim it and go. I can't see how the mold would survive deep inside the extract due to the sugar concentration, and any mold you miss should die in boiling.

Mold? Really? Could it possibly have been hops that seperated from the malt? I've seen this before.

Good call. Never use prehopped extract myself, but homebrewer_99 is right -- mold in extract is pretty hard to imagine with the high sugar content. If the extract is prehopped, sniff it and see if it smells like mold or hops.

The boil will kill it.

Hey, thanks for the replies. I skimmed off the mold and proceeded with the batch. Batch is cooling now and I will be pitching the yeast shortly. I am in Louisiana and should have refrigerated.

ummm.... what kind of kit is it? If it is a prehopped kit you may have taken out a great deal of the intended flavor by skimming off the "mold."

I doubt any caned extract could have mold due to the lack of oxygen. It was probably packed by someone after the manufacturer (or not mold but hops?)

Yeah, we're all interested -- canned or bulk extract? Pre-hopped or pure?

Mold is not uncommon in a kit where the malt is filled by the homebrew store particularly if you didn't refrigerate. Skimming the mold off works fine. Next time, make the kit sooner or get it in the fridge. I bet you won't make that mistake again.

Welcome to HBT!

edit: Where in the heck are you guys getting the pre-hopped thing? He said he was steeping grains which usually goes right along with adding hops to the pot.
