How to Store Blue Cheese the Right Way
Blue cheese is prized for its bold flavor and distinctive aroma, but it requires careful storage to maintain its quality and freshness. Proper storage not only preserves its taste and texture but also extends its shelf life, preventing spoilage and waste. Whether you’re wondering how to store blue cheese for the long term or seeking tips on how to store blue cheese in the refrigerator to last longer, this guide covers everything you need to know to keep your blue cheese at its best.
Basic Storage Guidelines for Blue Cheese
When it comes to how to store blue cheese properly, the key factors are controlling moisture, airflow, and temperature. Blue cheese is a semi-soft cheese with active mold cultures, so it needs an environment that allows it to breathe without drying out or becoming overly moist.
- Use airtight containers: To protect blue cheese from absorbing other odors in the fridge and to maintain humidity, store it in an airtight container. This prevents the cheese from drying out while also keeping unwanted smells at bay. Glass or BPA-free plastic containers with tight-fitting lids work well.
- Maintain the right temperature: Blue cheese should be stored in the refrigerator at a consistent temperature between 35°F and 45°F (1.5°C to 7°C). This range slows bacterial growth and preserves the cheese’s texture and flavor. Avoid the coldest part of the fridge (usually near the back or bottom) where temperatures can drop too low and cause the cheese to dry out or become crumbly.
- Placement in the fridge: Store blue cheese on a middle or upper shelf where the temperature is stable, rather than in the door where it’s subject to frequent temperature changes. Keeping it away from strong-smelling foods like onions or garlic will also help protect its delicate flavor.
By following these basic guidelines, you can keep your blue cheese fresh and flavorful for up to several weeks, depending on its initial freshness and packaging.
Wrapping Blue Cheese After Opening
Knowing how to wrap blue cheese after opening is crucial for preserving its quality. The way you wrap blue cheese affects its moisture balance and exposure to air, which in turn impacts its texture and flavor.
- Foil vs. wax paper: The best method is to wrap blue cheese in wax paper or cheese paper first. These materials are breathable, allowing the cheese to release moisture without drying out. Wax paper helps maintain the ideal humidity around the cheese, preventing it from becoming slimy or overly dry.
- After wrapping in wax paper, loosely cover the cheese with aluminum foil or place it in an airtight container. The foil acts as a secondary barrier to protect the cheese from strong odors and excessive air exposure while still allowing some breathability.
- Avoid plastic wrap: While it may seem convenient, plastic wrap is not recommended for storing blue cheese. It traps moisture, creating a wet environment that encourages unwanted bacterial growth and can cause the cheese to develop off-flavors or a slimy texture. Plastic wrap also suffocates the cheese, which can negatively affect the mold cultures that define blue cheese.
Proper wrapping after opening ensures your blue cheese stays fresh longer and maintains its characteristic taste and texture.
Crumbles vs Blocks: What's the Difference in Storage?
When considering how to store blue cheese crumbles, it’s important to understand that crumbled blue cheese behaves differently from blocks or wedges.
- Blue cheese crumbles dry out faster because they have more surface area exposed to air. This makes them more susceptible to moisture loss and flavor degradation.
- To preserve crumbles, store them in a small, airtight container lined with a slightly damp paper towel. The paper towel helps maintain humidity without making the cheese wet. Change the paper towel regularly to prevent mold growth.
- If you have a block or wedge of blue cheese, it’s easier to maintain freshness by wrapping it as described above (wax paper plus foil or container). You can crumble pieces as needed from the block, which helps preserve the bulk of the cheese longer.
- For crumbled blue cheese used in salads or recipes, consider buying smaller quantities to avoid prolonged storage, or freeze leftovers if you won’t use them soon (see below).
Can You Freeze Blue Cheese? (Pros and Cons)
Freezing blue cheese is a practical option when you have more cheese than you can consume before it spoils, but it comes with important considerations regarding texture, flavor, and usability. Understanding can I put blue cheese in the freezer and how freezing affects this distinctive cheese helps you make the most of your supply without compromising quality.
Pros of Freezing Blue Cheese
- Extended Shelf Life: Freezing blue cheese can significantly prolong its usability, allowing you to store it for several months beyond the typical refrigerator shelf life. This is especially useful if you have a large quantity or want to avoid waste.
- Preservation of Flavor: When properly wrapped and frozen quickly, blue cheese retains much of its characteristic tangy and pungent flavor. Freezing helps lock in aroma and taste, preventing spoilage and bacterial growth during storage.
- Convenience: Having frozen blue cheese on hand means you can thaw small portions as needed, making it easier to incorporate into recipes like sauces, dressings, or baked dishes without rushing to use it fresh.
Cons of Freezing Blue Cheese
- Texture Changes: Blue cheese has a crumbly texture that can become even more pronounced after freezing. The formation of ice crystals during freezing disrupts the cheese’s protein and fat structures, causing it to lose some creaminess and become grainy or mealy upon thawing. This is a common effect due to the expansion of water molecules into ice, which damages the cheese matrix.
- Flavor Mellowing: Freezing may slightly dull the vibrant, sharp tang of blue cheese. Some of the volatile compounds responsible for its pungent aroma and complex flavor can diminish, resulting in a milder taste. While still flavorful, the cheese may not have the same intensity as fresh.
- Not Ideal for Fresh Eating: Because of these texture and flavor changes, frozen and thawed blue cheese is generally better suited for cooking or crumbling into dishes rather than serving as a fresh cheese board centerpiece.
Blue Cheese Shelf Life: How Long Does It Last?
Blue cheese is a flavorful and distinctive cheese that adds a unique touch to any cheese platter or recipe. However, due to its moisture content and active mold cultures, it requires proper storage and handling to maintain its quality and safety. Understanding how long does blue cheese last in the refrigerator once opened or cut into pieces and knowing when to discard it are essential for enjoying this cheese at its best.
Shelf Life in the Fridge (Opened vs Unopened)
The shelf life of blue cheese varies significantly depending on whether it is unopened or has been cut into pieces or opened.
- Unopened Blue Cheese: When stored properly in the refrigerator, unopened blue cheese can last anywhere from 1 to 6 months. The wide range depends on factors such as the cheese type (store-bought vs artisanal), packaging, and storage conditions. Vacuum-sealed or shrink-wrapped blue cheese tends to have a longer shelf life because it is protected from air and moisture loss.
- Opened or Cut Blue Cheese: Once opened or cut, blue cheese’s shelf life shortens considerably. Typically, it will last about 3 to 4 weeks in the refrigerator if stored correctly. Exposure to air accelerates moisture loss and increases the risk of contamination. To maximize its longevity, wrap the cheese tightly in wax paper or cheese paper, then place it in an airtight container. Store it in the fridge at a consistent temperature between 35°F and 45°F (1.5°C to 7°C), ideally on a middle shelf away from door fluctuations.
- Store-Bought vs Artisanal: Store-bought blue cheeses often contain preservatives and are packaged to extend shelf life, making them more durable in the fridge. Artisanal blue cheeses, on the other hand, are typically fresher and less processed, so they require more careful handling and should be consumed sooner.
- Crumbled Blue Cheese: Crumbles have more surface area exposed to air and dry out faster. They usually last 2 to 3 weeks refrigerated and should be stored in small airtight containers lined with a slightly damp paper towel to maintain moisture.
Always check the "best by" date on the packaging as a guideline, but rely on your senses to determine freshness.
Can Blue Cheese Be Left Out?
Many people wonder how long can blue cheese sit out safely, especially when serving it at room temperature to enhance flavor.
- The general rule is that blue cheese should not be left out at room temperature for more than 2 hours. Beyond this, the risk of bacterial growth increases, which can lead to spoilage and potential foodborne illness.
- In warmer environments or during hot weather, this safe window shortens further. High temperatures accelerate bacterial growth and can cause the cheese to become overly soft, develop off odors, or grow unwanted molds.
- If blue cheese has been left out for longer than 2 hours, especially in warm or humid conditions, it’s safest to discard it.
- To enjoy blue cheese at its best, remove it from the refrigerator about 30 to 45 minutes before serving. This allows it to soften and release its full aroma and flavor without compromising safety.
Signs of Spoilage: Has Your Blue Cheese Gone Bad?
A common misconception is that blue cheese can never go bad because it is already moldy. This is false. While blue cheese contains specific, beneficial mold strains (Penicillium roqueforti or Penicillium glaucum), it can still spoil if improperly stored or kept too long.
To answer how do I know if my blue cheese has gone bad, watch for the following signs:
- Appearance: Fresh blue cheese features characteristic blue or green veins. Spoiled cheese may develop fuzzy white, green, pink, or black molds that differ from the natural veins. Any fuzzy or unusual mold growth is a warning sign.
- Smell: Blue cheese naturally has a strong, tangy aroma, but if it smells overwhelmingly ammonia-like, sour, or rotten, it has likely spoiled.
- Texture: Fresh blue cheese should be creamy or crumbly but not slimy or excessively dry. A slimy surface, hard chalky patches, or excessive dryness indicate spoilage.
- Taste: If the cheese tastes bitter, overly sharp, or off in any way, it’s best to discard it.
Consuming spoiled blue cheese can cause food poisoning symptoms such as nausea, vomiting, diarrhea, and stomach cramps. Some molds can also produce harmful mycotoxins, which pose health risks.
Busting the Myth: Blue Cheese Is Not Safe Forever
The idea that blue cheese is “already moldy” and therefore safe indefinitely is a myth. The blue mold in blue cheese is a controlled, edible mold strain that contributes to its flavor and texture. However, other unwanted molds and bacteria can contaminate the cheese over time, especially if storage conditions are poor.
Proper refrigeration, wrapping, and timely consumption are essential to prevent spoilage. Always inspect your blue cheese before eating, regardless of how long it has been stored.
Common Blue Cheese Questions
Is Blue Cheese Gluten-Free or Vegetarian?
Many people wonder, Is Blue Cheese Gluten Free? and Is Blue Cheese Vegetarian? The answers depend on the ingredients and manufacturing processes used.
Gluten-Free: Blue cheese is generally considered gluten-free. The mold cultures used to create the blue veins are sometimes grown on media that historically included gluten-containing substances like bread. However, research and testing have shown that the final cheese contains no detectable gluten, making it safe for people with celiac disease or gluten intolerance. Many commercial blue cheeses, including popular varieties like Roquefort, Stilton, and Gorgonzola, are labeled gluten-free. Still, it’s wise to check packaging or consult manufacturers if you have severe gluten sensitivity.
Vegetarian: Blue cheese is traditionally made using animal rennet, an enzyme derived from the stomach lining of calves, which means many blue cheeses are not vegetarian. However, some producers use microbial or vegetarian rennet alternatives, making those cheeses suitable for vegetarians. If you follow a vegetarian diet, look for blue cheeses explicitly labeled as vegetarian or made with microbial rennet. Artisanal cheesemakers often specify the type of rennet used, so it’s worth asking or checking labels.
For vegan alternatives, there are now plant-based blue cheeses made from cashews and cultured with vegan molds, replicating the flavor and texture of traditional blue cheese without any animal products.
Can You Eat Blue Cheese While Pregnant?
The question Can You Eat Blue Cheese While Pregnant? is common due to concerns about food safety during pregnancy.
Blue cheese is often made from unpasteurized milk, which can harbor Listeria monocytogenes, a harmful bacterium that poses risks to pregnant women and their babies. Therefore, many health authorities recommend avoiding blue cheese made from raw milk during pregnancy.
However, blue cheeses made from pasteurized milk are generally considered safe to eat during pregnancy, provided they are stored and handled properly. Always check the label to confirm pasteurization. If in doubt, consult your healthcare provider.
To minimize risk, pregnant women should avoid soft blue cheeses that are unpasteurized or have a high moisture content, as these conditions are more conducive to bacterial growth.
Can Cats Eat Blue Cheese?
Many pet owners ask, Can Cats Eat Blue Cheese? The short answer is no, it’s best to avoid feeding blue cheese to cats.
Blue cheese contains high levels of salt, fat, and mold cultures that are not suitable for feline digestion. The mold in blue cheese, while safe for humans, can be toxic to cats and cause digestive upset, including vomiting and diarrhea.
Additionally, dairy products in general can cause lactose intolerance symptoms in adult cats, such as stomach upset and gas.
If your cat accidentally eats a small amount of blue cheese, monitor them for any adverse reactions and contact your veterinarian if symptoms occur. For a safe treat, stick to cat-specific snacks and foods.
Does Blue Cheese Melt?
This is a common question for those who want to use it in cooking.
Blue cheese does melt, but it behaves differently from milder cheeses like mozzarella or cheddar. It tends to soften and become creamy rather than stretch. This makes it ideal for sauces, dressings, and toppings where you want rich flavor and smooth texture.
- In sauces: Blue cheese melts beautifully into cream or butter-based sauces, adding depth and tang. Classic examples include blue cheese dressing or steak sauces.
- On burgers: Crumbled or sliced blue cheese melts slightly on a hot burger, providing a creamy, pungent contrast to the savory meat.
- Fondue: Blue cheese can be blended into cheese fondues for a sharp, complex flavor profile, often mixed with other milder cheeses to balance intensity.
Because blue cheese melts quickly and can become oily if overheated, it’s best to melt it gently over low heat or fold it into warm dishes at the end of cooking.
How Long Can Blue Cheese Sit Out? How to Store Blue Cheese in the Refrigerator to Last Longer and Maximize Shelf Life
When it comes to blue cheese, questions like how long can blue cheese sit out?, how should I store blue cheese in the refrigerator to last longer?, and how long does blue cheese last in the refrigerator once opened or cut into pieces? are common. Many also wonder is it true that blue cheese can never go bad because it is already moldy? and seek practical advice on how to store blue cheese in refrigerator and how to store blue cheese for long time. Here’s a comprehensive overview to help you enjoy blue cheese safely and at its best.
How Long Can Blue Cheese Sit Out?
Blue cheese is perishable and should not be left at room temperature for long. The general rule is that blue cheese can safely sit out for up to 2 hours. Beyond this, the risk of bacterial growth increases significantly, which can lead to spoilage and foodborne illness. In warmer environments, this safe window shortens even further. To enjoy blue cheese at its best, remove it from the fridge about 30–45 minutes before serving to allow it to soften and release its full flavor without compromising safety.
How Should I Store Blue Cheese in the Refrigerator to Last Longer?
Proper storage is key to extending the life of blue cheese and preserving its distinctive flavor and texture. Here’s how to store blue cheese in the refrigerator for maximum freshness:
- Wrap it tightly: Use breathable materials like wax paper or cheese paper to wrap the cheese first. This allows the cheese to breathe and prevents it from drying out. Avoid direct contact with plastic wrap as it traps moisture and can cause spoilage.
- Place in an airtight container: After wrapping, put the cheese in a glass or BPA-free plastic airtight container. This protects it from absorbing other odors in the fridge and helps maintain humidity.
- Store in the coldest part of the fridge: Ideally, keep blue cheese on a middle or lower shelf where the temperature is stable, typically between 35°F and 45°F (1.5°C to 7°C). Avoid storing it in the fridge door where temperature fluctuates.
- Avoid moisture buildup: Excess moisture promotes unwanted mold growth. Change wrapping regularly if it becomes damp.
How Long Does Blue Cheese Last in the Refrigerator Once Opened or Cut Into Pieces?
Once opened or cut, blue cheese typically lasts 3 to 4 weeks in the refrigerator when stored properly. Unopened blue cheese can last much longer up to 1 to 6 months depending on packaging and type. Store-bought blue cheeses sealed in vacuum packaging often have longer shelf lives than artisanal varieties, which should be consumed sooner.
Crumbled blue cheese dries out faster and generally lasts 2 to 3 weeks refrigerated. To extend its life, store crumbles in a small airtight container lined with a slightly damp paper towel to maintain humidity.
Is It True That Blue Cheese Can Never Go Bad Because It Is Already Moldy?
This is a common myth. While blue cheese contains safe, edible mold strains (such as Penicillium roqueforti), it can go bad if not stored properly or kept too long. Spoilage occurs when unwanted molds or bacteria grow, or when the cheese dries out excessively.
Signs of spoilage include:
- Unusual fuzzy mold in colors like white, pink, or black that differ from the characteristic blue veins
- Strong ammonia or sour odors
- Slimy or excessively dry texture
- Off or bitter taste
If you notice any of these, it’s best to discard the cheese to avoid health risks.
How to Store Blue Cheese for Long Time
To store blue cheese for a longer time while maintaining quality:
- Keep it tightly wrapped in wax paper or cheese paper, then place it in an airtight container.
- Store at a consistent refrigerator temperature between 35°F and 45°F.
