I'm assuming you're washing with beer and salt? I've not washed with beer, just brine, but with brine washing you will get b.linens from the wild. No need to add any. I would think something similar will happen with beer brine washes. The rind should smear up (go like a paste) and it will smell, and b.linens gives a red or orange colour. So, basically, without further information, I would think things are actually going to plan.
