Blue cheese, with its distinctive veining and pungent aroma, is a favorite among cheese enthusiasts. However, its strong flavor and high moisture content raise concerns about its shelf life. Does blue cheese go bad quickly? The answer lies in understanding the factors that affect its longevity and learning how to store it properly.
Factors Affecting the Shelf Life of Blue Cheese
Several factors contribute to the shelf life of blue cheese, including:
Type of Blue Cheese
Not all blue cheeses are created equal. Different types of blue cheese have varying shelf lives due to their unique characteristics. For example:
- Soft-ripened blue cheeses, like Brie or Camembert, have a shorter shelf life (around 1-2 weeks) due to their high moisture content and soft texture.
- Semi-soft blue cheeses, like Gorgonzola or Roquefort, can last longer (around 2-4 weeks) due to their slightly firmer texture and lower moisture content.
- Hard blue cheeses, like Stilton or Danish Blue, have a longer shelf life (around 4-6 weeks) due to their low moisture content and dense texture.
Storage Conditions
Proper storage is crucial in extending the shelf life of blue cheese. Factors like temperature, humidity, and light exposure can significantly impact its longevity.
- Temperature: Blue cheese should be stored in a cool, consistent temperature between 35°F and 45°F (2°C and 7°C). Avoid storing it near heat sources or in direct sunlight.
- Humidity: Blue cheese prefers a relatively high humidity environment, typically between 50% and 70%. You can store it in a sealed container or plastic bag to maintain humidity.
- Light exposure: Blue cheese can become discolored or develop off-flavors when exposed to direct light. Store it in a dark or shaded area to prevent this.
Handling and Packaging
How you handle and package blue cheese can also affect its shelf life.
- Handling: Avoid touching or handling blue cheese excessively, as this can introduce bacteria and contaminants that can shorten its shelf life.
- Packaging: Store blue cheese in its original packaging or wrap it tightly in plastic wrap or aluminum foil to prevent moisture loss and contamination.
Signs of Spoilage in Blue Cheese
While blue cheese can be a bit pungent, there are distinct signs that indicate it has gone bad. Look out for:
Visual Cues
- Slime or mold: A thick, slimy, or fuzzy growth on the surface of the cheese can indicate spoilage.
- Discoloration: Blue cheese can develop an unusual color or become more pale than usual.
- Cracks or breaks: If the cheese develops cracks or breaks, it may be a sign of drying out or spoilage.
Olfactory Cues
- Ammonia smell: A strong, pungent ammonia smell can indicate spoilage.
- Sour or bitter taste: If the cheese tastes sour or bitter, it may be past its prime.
Texture Changes
- Softening or hardening: If the cheese becomes too soft or hard, it may be a sign of spoilage.
- Slimy or sticky texture: A slimy or sticky texture can indicate the presence of bacteria or mold.
Extending the Shelf Life of Blue Cheese
While blue cheese can be a bit finicky, there are ways to extend its shelf life:
Freezing Blue Cheese
Freezing blue cheese can help extend its shelf life. Here’s how:

What is the typical shelf life of blue cheese?
The shelf life of blue cheese can vary depending on factors such as the type of blue cheese, storage conditions, and handling practices. Generally, blue cheese can last anywhere from a few weeks to several months when stored properly. Soft-ripened blue cheeses, like Gorgonzola or Roquefort, tend to have a shorter shelf life (around 4-6 weeks) due to their higher moisture content. In contrast, harder blue cheeses, such as Stilton or Danish Blue, can last longer (up to 3-4 months).
It’s essential to note that blue cheese is a living product, and its quality will degrade over time. Even if blue cheese is still within its shelf life, its flavor and texture may not be optimal. To ensure the best quality, it’s recommended to consume blue cheese within a few weeks of opening.
How should I store blue cheese to extend its shelf life?
To extend the shelf life of blue cheese, it’s crucial to store it properly. Blue cheese should be wrapped tightly in plastic wrap or aluminum foil and placed in a sealed container. This will help prevent air from reaching the cheese and causing it to dry out or develop off-flavors. It’s also essential to keep blue cheese away from strong-smelling foods, as it can absorb odors easily.
Refrigeration is also vital for maintaining the quality of blue cheese. Store blue cheese in the coldest part of the refrigerator, typically the bottom shelf, at a consistent temperature below 40°F (4°C). Avoid freezing blue cheese, as this can cause the texture to become crumbly and the flavor to be affected.
Can I freeze blue cheese to extend its shelf life?
While it’s technically possible to freeze blue cheese, it’s not the recommended storage method. Freezing can cause the texture of blue cheese to become crumbly and the flavor to be affected. However, if you need to store blue cheese for an extended period, freezing can be a viable option. It’s essential to wrap the blue cheese tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag to prevent freezer burn.
When freezing blue cheese, it’s crucial to note that the quality may not be the same as freshly stored cheese. Frozen blue cheese is best used in cooked dishes or as a flavor enhancer, rather than served on its own. To use frozen blue cheese, simply thaw it in the refrigerator or at room temperature, and then use it as desired.
How can I tell if blue cheese has gone bad?
Determining whether blue cheese has gone bad can be a bit tricky, as it’s a strong-smelling and pungent cheese. However, there are some signs to look out for. If blue cheese has developed an off or ammonia-like smell, it may be past its prime. Additionally, if the cheese has become slimy or has visible mold growth (beyond the typical veining), it’s likely gone bad.
Another way to check if blue cheese has gone bad is to examine its texture. If the cheese has become dry and crumbly or has developed an unpleasantly soft or runny texture, it may be past its shelf life. Trust your senses – if the cheese looks, smells, or tastes off, it’s best to err on the side of caution and discard it.
Can I still use blue cheese if it’s past its expiration date?
If blue cheese is past its expiration date, it’s not necessarily a guarantee that it’s gone bad. Blue cheese can still be safe to consume and retain its quality for a short period after the expiration date. However, it’s essential to inspect the cheese carefully for any signs of spoilage, such as off smells, sliminess, or mold growth.
If the blue cheese appears to be in good condition, you can still use it. However, it’s crucial to note that the quality may not be optimal, and the flavor and texture may have degraded. If you’re unsure whether the blue cheese is still good, it’s always best to err on the side of caution and discard it to avoid any potential food safety issues.
Is it safe to eat blue cheese with mold growth?
Blue cheese is known for its veining, which is a type of mold growth. However, not all mold growth is safe to eat. If the mold growth is limited to the typical veining and has a white or blue-green color, it’s generally safe to eat. However, if the mold growth is excessive, has a different color, or has a slimy texture, it’s best to discard the cheese.
It’s also essential to note that some people may be more sensitive to mold growth than others. If you’re pregnant, have a weakened immune system, or are concerned about food safety, it’s best to err on the side of caution and discard any blue cheese with mold growth.
Can I make blue cheese last longer by cutting off moldy parts?
While it may be tempting to cut off moldy parts of blue cheese to extend its shelf life, this is not a recommended practice. Blue cheese is a porous cheese, and mold can penetrate deep into the cheese. Cutting off moldy parts may not remove all the mold, and the remaining cheese may still be contaminated.
Additionally, cutting off moldy parts can also affect the texture and flavor of the remaining cheese. It’s generally best to discard any blue cheese with excessive mold growth or other signs of spoilage to ensure food safety and quality. If you’re concerned about waste, consider purchasing smaller blocks of blue cheese or freezing it to extend its shelf life.
