How to Store Cheese: From Mozzarella to Cream Cheese
Cheese is “alive”—it continues to ripen and change. Storage depends entirely on moisture content. Hard cheese is durable; soft cheese is fragile.
The “Mold Rule”: Cut or Toss?
This is the most important safety rule for cheese lovers.
1. Hard Cheese (Cheddar, Parmesan, Swiss)
- Rule: Cut it off.
- The mold roots can’t penetrate the dense structure. Cut at least 1 inch around and below the mold spot. The rest is safe to eat.
- Fridge Life: Unopened blocks last 6 months (180 days). Opened blocks last 3 to 4 weeks (21-28 days).
2. Soft Cheese (Brie, Goat, Cream Cheese, Cottage Cheese)
- Rule: Toss it.
- If you see mold on soft cheese, it’s contaminated throughout. Do not try to salvage it.
- Fridge Life: Lasts 1 to 2 weeks (7-14 days).
Freezing Cheese
Freezing extends shelf life but often alters texture.
- Blocks (Cheddar/Mozzarella): Freeze well for 3 to 4 months. Texture becomes crumbly, so use for cooking (mac and cheese, pizza).
- Soft Cheese (Brie/Goat): Can be frozen for up to 6 months, but expect significant texture changes. Best used in sauces or baked dishes after thawing.
- Parmesan (Grated): Freezes perfectly for up to 1 year.
Storage Tips
- Don’t use plastic wrap: It suffocates cheese (ammonia smell).
- Use Parchment/Wax Paper: Wrap the cheese in paper, then put it in a baggie. This lets it breathe without drying out.
Frequently Asked Questions
Can you freeze fresh mozzarella cheese?
Yes, but the texture will change. It becomes crumbly, making it suitable only for melting in cooked dishes, not for fresh salads.
How long is cream cheese good after expiration date?
Cream cheese is strictly perishable. Unopened, it might last 1-2 weeks past the date, but once opened, finish it within 10 days.
How to store fresh mozzarella cheese?
Keep it in its liquid (brine) or wrap tightly in plastic. It dries out quickly and picks up fridge odors.
