Blue cheese, with its pungent aroma and creamy texture, is a culinary delight for many. Its unique flavor profile, a result of the presence of mold, adds a distinctive touch to salads, pasta dishes, and even burgers. However, the very nature of this mold-ripened cheese presents a question that often arises in kitchens: how long does blue cheese last in the refrigerator? Understanding the shelf life of blue cheese is crucial to ensure its safety and prevent any unwanted surprises when you reach for that creamy indulgence.
The Science Behind Blue Cheese’s Shelf Life
Blue cheese’s distinctive character stems from the deliberate introduction of specific types of mold, primarily Penicillium roqueforti and Penicillium glaucum, during its production. These molds break down the cheese’s proteins and fats, creating the characteristic blue veins and pungent flavor. However, these same molds can also contribute to the cheese’s spoilage if not properly stored.
Factors Affecting Blue Cheese Shelf Life
Several factors influence how long blue cheese remains fresh and safe to consume:
- Type of Blue Cheese: Different varieties of blue cheese have varying moisture levels and fat content, which can affect their shelf life. Generally, drier blue cheeses tend to last longer than creamier varieties.
- Storage Conditions: Proper storage is paramount. The refrigerator temperature, humidity, and the type of packaging all play a role in preserving the cheese’s quality.
- Initial Quality: The freshness of the blue cheese when purchased significantly impacts its shelf life. Look for firm, well-formed cheese with minimal signs of mold growth or discoloration.
Proper Storage Techniques for Blue Cheese
To maximize the shelf life of your blue cheese and ensure its safety, follow these storage guidelines:
Refrigerator Storage
Store blue cheese in the coldest part of your refrigerator, ideally at a temperature of 40°F (4°C) or below. Avoid storing it near strong-smelling foods, as the flavors can transfer.
Packaging
Wrap the blue cheese tightly in plastic wrap or aluminum foil to prevent it from drying out and absorbing odors from other foods in the refrigerator. You can also store it in an airtight container.
Freezing
While not ideal for preserving the texture, you can freeze blue cheese for extended storage. Wrap it tightly in plastic wrap and then in aluminum foil. Frozen blue cheese will last for several months. Thaw it in the refrigerator overnight before using.
Recognizing Signs of Spoilage in Blue Cheese
Even with proper storage, blue cheese can eventually spoil. Be vigilant and discard any cheese that exhibits the following signs:
- Strong, unpleasant odor: A sharp, ammonia-like smell indicates spoilage.
- Discoloration: Mold growth beyond the characteristic blue veins or any greenish or brownish discoloration suggests spoilage.
- Slimy or sticky texture: A change in texture, becoming slimy or sticky, is a sign of bacterial growth.
General Guidelines for Blue Cheese Shelf Life
Here’s a general guide to the shelf life of blue cheese in the refrigerator:
| Type of Blue Cheese | Shelf Life (Refrigerated) |
|---|---|
| Hard Blue Cheese (e.g., Roquefort) | 2-3 weeks |
| Semi-Hard Blue Cheese (e.g., Gorgonzola) | 1-2 weeks |
| Creamy Blue Cheese (e.g., Danablu) | 1 week |
Remember, these are just estimates. Always use your senses to determine the freshness of your blue cheese. If in doubt, err on the side of caution and discard it.

- Avoid consuming blue cheese if you are pregnant, immunocompromised, or have a history of foodborne illness.**
Frequently Asked Questions
How Long Does Blue Cheese Last in the Refrigerator?
How long can I keep blue cheese in the fridge?
The shelf life of blue cheese in the refrigerator depends on its type and storage conditions. Generally, hard blue cheeses like Roquefort can last 2-3 weeks, while semi-hard and creamy varieties last 1-2 weeks and 1 week, respectively. Always check for signs of spoilage before consuming.
Can I freeze blue cheese?
Yes, you can freeze blue cheese for longer storage. Wrap it tightly in plastic wrap and then aluminum foil. It will last for several months in the freezer but may change texture upon thawing.
What does it mean if blue cheese has white mold on it?
White mold on blue cheese is normal and part of the cheesemaking process. It’s different from the blue veins, which are caused by the specific mold used in blue cheese production. However, if you see any other discoloration or unusual growth, it’s best to discard the cheese.
