How long does Parmesan last?
In the fridge: 60 days
In the freezer: 365 days
Parmesan is the longest-living cheese — 6+ weeks in the fridge once opened, sometimes months. Whole wedges in their natural rind last longest; grated lasts 2–3 weeks before flavor fades. Pre-grated tubs from the supermarket are shelf-stable for months unopened. Mold on a wedge is mostly cosmetic; cut it away with 1cm margin. Hard rinds can be saved and added to broths for flavor. Freezing whole wedges or grated portions extends life to a year.
