America’s Test Kitchen proving the worth of proper cheese storage:
How it’s supposed to work: As cheese releases moisture, tight wrapping encourage mold, while loose ones let it dry out and harden. These bags’ two-ply material—wax-coated paper lined with thin, porous polyethylene plastic—allows moisture to wick off the cheese but not escape entirely.
How we tested it: We wrapped brie, goat cheese, and cheddar in the cheese bags and in a homemade double-wrapped combination of parchment and foil, which we’ve found works better than wrapping cheese in the usual plastic wrap or bag. Then we put both sets of samples in the refrigerator and checked on them every other day for a month.
