I’m fairly new to cheesemaking too, but I’ve used our wellhouse/root cellar to age cheeses in for a couple of years. The flavor was MUCH better than in the cheeses I meant to age in our fridge in my first year making cheese, and I didn’t notice any off-flavors reminiscent of the root cellar smell. However, I had a lot of trouble with mold. (No surprise there—mold tends to grow on the walls in the wellhouse, which I guess means the humidity is good.) This year I’m thinking about using a dedicated fridge instead.
