So, I am finding myself in a similar situation to others in this thread. About 2 weeks ago, I made a traditional cheddar and bandaged it, using vegetable shortening and pressing the bandage well (I thought) into the cheese.
Lo and behold, in the past few days, I observed spots of mold growing under the bandage, and in some cases the bandage separating a little from the underlying cheese. My 'cave' is at about 55 degrees, and I recently started measuring humidity to find it was only 50%. I've added more water and it's up to 70% or so now.
Anyhow, I removed the bandage and used brine-soaked cheesecloth to remove the mold, which was a very thin layer between the cheese surface and the shortening mostly. Mostly green, maybe a little grey and orange/rust color. Nothing seems to have penetrated the cheese at all.
So, my question really is - how long can/should I let the cheese sit before re-bandaging. It's been in the 'cave' for about a day now, naked, and I think it seems fairly dry. Would appreciate any advice or thoughts on strategy.
Also, I have lard now and when I re-bandage I think I'll use that.
Edit: No, I did not air-dry the cheese after pressing, just went straight to the bandaging and into the 55 deg. 'cave'. I see from some other threads that perhaps this may have led to shrinkage during aging, perhaps contributing to my current issues. Also, after 1 day the cheese I unwrapped developed significant cracks. I larded it all over and am in the process of re-bandaging.
