If strongly scented foods such as chopped onions are stored nearby, cheese can easily absorb their smells and tastes. To keep your cheese at its best, one recommendation is to keep it in a separate enclosed space, away from encroaching aromas and tastes. It is also advisable to tightly cover opened cheeses (whether soft or hard) in a plastic wrap to help protect them from moisture and mold. If you bought it wrapped in paper, remove the paper and replace with clingy plastic wrap, or it will dry out. For brine- or water-packaged cheeses such as bocconcini or feta, keep them in their liquid, and rinse off cheese as you use it. Hard cheese like Parmesan will keep for up to 10 months in the fridge, and soft cheese will last about one week. Keep an eye on expiry dates.
