So I got busy and I kind of forgot about a couple of batches for a while. I opened up the fermentation freezer and as the title says there's mold in the chamber.

The carboys are glass and the airlocks are still full of starsan so I'm wondering if the batches are screwed or if there's a chance they're still ok. I haven't tasted or smelled them yet.

What are people doing to combat moisture in their fermentation chambers?

I just gave them each a whiff and they don't smell off. I'm going to go ahead and keg them anyway, but hold off on giving them any co2 until I hear back

If I had a fermentation chamber I would use Damprid from CT. It is a dessicant (CaCl2 I think) that you would just place in the chamber. I use it in my keezer and it works great.

cool, I'll be sure to get some of that

I pulled a sample of each as I filled the kegs and they didn't taste noticeably off... worst case ontario I have some sacrificial suds to give to moochers I don't want coming back for more

Its happened to be before and the beer turned out fine. The spores would have a hard time making it in there with an airlock with sanitizer. Next time, you might want to spray around the bung before you take it off to kill anything on the surface.

I'll take those off your hands to dump since they are obviously ruined

What cartoonCod said. I would have pulled it out,wiped the carboys down,let the air settle, then transferred.

Dollarama sells a knock off Damprid that I use in my fermentation chamber. Completely fixed up the moisture issue for me.

I'm going to pick up an Eva-Dry 500 http://www.eva-dry.com/products/eva-dry ... umidifier/ for my keezer / part-time fermentation chamber. I like that it's reusable/rechargeable, nothing to dump/replace, sounds like it lasts a long time.
