A small spot of mold on hard cheese is not a death sentence. Cut at least 1 inch around and below the mold spot. This does NOT apply to soft cheeses; those go straight in the trash.
How to Store Cheese (Hard and Semi-Hard)
Wrap in wax paper or parchment, then loosely in plastic wrap. Do not wrap tightly in plastic alone; cheese needs to breathe slightly.
How to Tell if Cheese (Hard and Semi-Hard) Has Gone Bad
Look for these signs that cheese (hard and semi-hard) has spoiled: mold growth beyond the original cultures, ammonia smell, excessively dried or cracked surface.
The Professor's rule: When in doubt, throw it out. No meal is worth food poisoning.
The Bottom Line
Properly stored cheese (hard and semi-hard) stays safe for 21–42 days in the fridge. Always store in airtight containers, refrigerate within 2 hours of purchase or preparation, and trust your senses. If something looks, smells, or feels off, discard it regardless of how many days it has been. Freezing is always an option if you will not use it within the refrigerator window.
