I thought it was only yeast rafts, but when I got home today, my fears were confirmed- definitely mold growing on the top of my inactive wort. Oddly enough, I read in "How to Brew" just today that mold is not a killer for sure. Is there anything I can do or am I better off dumping and starting over? I still have 5 gallons in a different fermenter doing good so not all will be lost.

How do you know for sure? Post a pic. I'm sure everybody would love to see an actual infection.

The beer might be fine. Just proceed as if all is well.

If your positive it's mold then I would rack to a new container. Post some pics so we can all see.

I will see if I can get a pic. Also, I just tested the gravity and obviously my yeast never got started. OG was 1.052, gravity now after 5 days is 1.050 and no action. If I decide to go on, can I order a new yeast pack and still be able to salvage the wort? (It would take 3-5 days to get to me.

Might as well give it a try. I would order more than just yeast though, since your ordering anyway.also you should keep an extra pack or two of yeast around just incase. I,ve had to re pitch before and was glad I had it around

I missed the part about your gravity reading. I would be concerned if you had mold on unfermented wort. If there was enough o2 in there for there to have been mold development then more than likely the wort soured as well.

Was that liquid or dry yeast? if dry, did you rehydrate or pitch directly?
(doesn't matter, except for temps.) rehydrate temp - not to exceed 104.

Pitching temp - obviously not to exceed 104 either, but better at 65F

something was too hot and killed the yeast, perhaps? Watch your temps, they're important.

a spare packet or two of dry in the refrigerator for just such an occasion.
Oh, and if you have to wait 3 days for yeast, don't bother racking until the new yeast comes, or you may have more mold growing on the newly racked wort.

Would racking and re-boiling sufficiently sterilize the wort before cooling it again and pitching new yeast?

Or would this cause more problems than it's worth?
