That's pretty long Isn't it? I mean, traditional Crottin is considered "affiné" by day 21 (tiny 60g to 160g cheese).
Do you mix the 18%-22% salt in the brandy or beer? do you re-use such brine a couple of times or always make a fresh one?
Crottin de Pays is a 50-60 gr cheese with affinage of arround 2 weeks.
Crottin de Chavignol is a 60-110 gr cheese. Within the AOC Regulation, affinage should last at least 10 days, but 2-4 weeks is allowed as well, therefore 3 weeks is OK for me.
So, 8 weeks sounds to long, but, as this is far of being a "legal"
Crottin, I do wait for this period for the washed ones. And BTW, those cheeses I've show, are made from cow milk, not goat milk.
I do not mix any of the washing liquids, and I use them separately on each cheese, small amount of liquid at a time, refeeling the same container, all kept in the fridge.
