Cheese, in its diverse and delicious forms, is a culinary staple enjoyed worldwide. From sharp cheddar to creamy brie, a block of cheese is a welcome addition to any meal or snack. However, improperly stored cheese can quickly become dry, moldy, or lose its distinct flavor profile. This guide provides you with the knowledge and techniques to store your cheese bricks properly, ensuring they remain fresh, flavorful, and enjoyable for as long as possible.
Understanding Cheese Composition and Spoilage
Before diving into storage methods, understanding the basic composition of cheese and how it spoils is essential. Cheese is a complex food product consisting primarily of milk proteins (casein), fat, water, and cultures. The specific ratios of these components vary widely depending on the type of cheese, influencing its texture, flavor, and shelf life.
Cheese spoilage can occur through several mechanisms. Mold growth is perhaps the most visible sign, but it’s not always the only indicator. The texture can change, becoming dry, crumbly, or excessively hard. Flavor alterations, such as a sour or ammonia-like taste, can also signal spoilage. Additionally, oxidation can occur, leading to off-flavors and discoloration.
The Role of Moisture
Moisture plays a crucial role in cheese preservation. Too much moisture can encourage mold growth, while too little can lead to dryness and cracking. The ideal storage environment aims to maintain a balance, preventing excessive moisture loss while inhibiting mold formation.
The Impact of Air Exposure
Exposure to air is another key factor influencing cheese spoilage. Air can lead to oxidation, drying out the cheese and altering its flavor. Therefore, minimizing air exposure is a fundamental principle of proper cheese storage.
General Guidelines for Storing Cheese
Regardless of the specific type of cheese, some general guidelines apply to all storage scenarios. Following these principles will significantly extend the shelf life and maintain the quality of your cheese brick.
The Importance of Temperature Control
Temperature is arguably the most critical factor in cheese storage. The ideal temperature range for most cheeses is between 35°F and 45°F (2°C and 7°C). This range slows down microbial growth and enzymatic activity, preserving the cheese’s flavor and texture.
The refrigerator’s cheese drawer (if available) is typically the best location because it offers a slightly higher humidity level compared to the rest of the refrigerator. Avoid storing cheese in the refrigerator door, as temperature fluctuations are more significant in this area.
Selecting the Right Wrapping Material
The wrapping material you choose significantly impacts the cheese’s ability to retain moisture and prevent air exposure. Different materials offer varying degrees of protection, and selecting the appropriate one is crucial for optimal storage.
Minimizing Handling
Each time you handle a block of cheese, you introduce new bacteria and increase the risk of contamination. Therefore, minimize handling as much as possible. Always wash your hands thoroughly before handling cheese, and use clean utensils to cut or portion it.
Specific Storage Methods Based on Cheese Type
Different types of cheese have different characteristics and, therefore, require slightly different storage approaches. Understanding the nuances of each cheese type will help you tailor your storage methods for optimal preservation.
Storing Hard Cheeses (Cheddar, Parmesan, Gruyere)
Hard cheeses, such as cheddar, Parmesan, and Gruyere, have a relatively low moisture content, making them less susceptible to mold growth compared to softer cheeses. However, they are still vulnerable to drying out and developing a hard, unappetizing rind.
Wrapping Options for Hard Cheeses:
Wax Paper: A good option for allowing the cheese to breathe while providing some protection against moisture loss. Wrap the cheese tightly in wax paper and then place it in a resealable plastic bag.
Parchment Paper: Similar to wax paper, parchment paper provides a breathable barrier.
Cheese Paper: Specially designed for cheese storage, cheese paper offers an ideal balance of breathability and moisture retention. It’s typically a two-ply paper with a porous inner layer and a non-porous outer layer.
Before wrapping, consider lightly oiling the cut surfaces of the cheese with olive oil. This can help prevent them from drying out. Store the wrapped cheese in the refrigerator’s cheese drawer. Inspect the cheese regularly for any signs of mold growth. If mold appears, cut it away, being sure to remove at least ½ inch around the mold spot. Rewrap the cheese in fresh wrapping.
Storing Semi-Hard Cheeses (Gouda, Monterey Jack, Edam)
Semi-hard cheeses, like Gouda, Monterey Jack, and Edam, have a slightly higher moisture content than hard cheeses and, therefore, require slightly more attention to prevent drying out.
Wrapping Options for Semi-Hard Cheeses:
Plastic Wrap: Provides a good barrier against moisture loss, but can trap too much moisture and encourage mold growth if not managed carefully. Wrap the cheese tightly in plastic wrap, ensuring there are no air pockets.
Cheese Paper: An excellent choice for semi-hard cheeses, providing a balance of breathability and moisture retention.
Resealable Plastic Bags: After wrapping the cheese in plastic wrap or cheese paper, place it in a resealable plastic bag to provide an extra layer of protection.
Similar to hard cheeses, inspect semi-hard cheeses regularly for mold. If mold appears, cut it away and rewrap the cheese.
Storing Soft Cheeses (Brie, Camembert, Feta)
Soft cheeses, such as brie, Camembert, and feta, have a high moisture content and are the most perishable types of cheese. They require careful handling and storage to prevent spoilage.
Wrapping Options for Soft Cheeses:
Original Packaging: If possible, store soft cheeses in their original packaging. This packaging is often designed to maintain the cheese’s optimal moisture level.
Plastic Wrap: Wrap the cheese tightly in plastic wrap, ensuring there are no air pockets.
Resealable Plastic Containers: After wrapping the cheese in plastic wrap, place it in a resealable plastic container to provide an extra layer of protection and prevent odors from spreading in the refrigerator.
Feta cheese is often stored in brine. If you purchase feta in brine, store it in the refrigerator in its original brine solution. If you make your own feta, store it in a homemade brine solution of water and salt. Change the brine regularly to keep the feta fresh.
Storing Blue Cheeses (Gorgonzola, Stilton, Roquefort)
Blue cheeses, such as Gorgonzola, Stilton, and Roquefort, have a distinct flavor and aroma due to the presence of mold cultures within the cheese. These cheeses require careful storage to prevent the mold from overgrowing and altering the flavor.
Wrapping Options for Blue Cheeses:
Original Packaging: If possible, store blue cheeses in their original packaging.
Plastic Wrap: Wrap the cheese tightly in plastic wrap, ensuring there are no air pockets.
Resealable Plastic Containers: After wrapping the cheese in plastic wrap, place it in a resealable plastic container to contain the strong aroma and prevent it from affecting other foods in the refrigerator.
It is normal for blue cheese to develop more mold on the surface during storage. However, if the mold becomes excessively overgrown or the cheese develops an off-flavor, it should be discarded.
Advanced Storage Techniques
Beyond the basic storage methods, some advanced techniques can further extend the shelf life and maintain the quality of your cheese bricks.
Vacuum Sealing
Vacuum sealing removes air from around the cheese, significantly reducing oxidation and preventing mold growth. This method is particularly effective for hard and semi-hard cheeses. However, it’s not recommended for soft cheeses, as the vacuum pressure can crush them.
To vacuum seal cheese, use a vacuum sealer to remove the air from a bag containing the cheese. Ensure the bag is properly sealed to prevent air from re-entering. Vacuum-sealed cheese can be stored in the refrigerator for significantly longer than conventionally wrapped cheese.
Freezing Cheese
Freezing cheese can be a useful option for preserving it for extended periods. However, freezing can alter the texture and flavor of some cheeses. Hard and semi-hard cheeses generally freeze better than soft cheeses.
To freeze cheese, wrap it tightly in plastic wrap and then place it in a freezer bag. Remove as much air as possible from the bag before sealing it. Frozen cheese can be stored for several months.
When thawing cheese, thaw it slowly in the refrigerator. This will help minimize the changes in texture and flavor. Keep in mind that frozen and thawed cheese may be more crumbly than fresh cheese. It is best used in cooked dishes where the texture is less critical.
Using Olive Oil or Butter as a Protective Layer
For hard cheeses, coating the cut surfaces with a thin layer of olive oil or melted butter can help prevent them from drying out. The oil or butter creates a barrier that reduces moisture loss and protects against oxidation.
Apply the oil or butter to the cut surfaces of the cheese using a clean brush. Wrap the cheese as usual and store it in the refrigerator.
Signs of Spoilage: When to Toss Your Cheese
Despite your best efforts, cheese can still spoil. Knowing the signs of spoilage is crucial to avoid consuming unsafe cheese.
Excessive Mold Growth: While some mold on cheese is normal, excessive mold growth, especially if it’s not the type of mold typically found on that type of cheese, is a sign of spoilage.
Off-Odor: A sour, ammonia-like, or otherwise unpleasant odor is a clear indication that the cheese has spoiled.
Slimy Texture: A slimy or sticky texture on the surface of the cheese is a sign of bacterial growth and spoilage.
Significant Discoloration: While some color changes are normal in cheese, significant discoloration, such as yellowing or browning, can indicate spoilage.
Altered Flavor: If the cheese tastes sour, bitter, or otherwise off, it should be discarded.
When in doubt, it’s always best to err on the side of caution and discard cheese that shows signs of spoilage. Consuming spoiled cheese can lead to foodborne illness.
Troubleshooting Common Cheese Storage Problems

What is the best temperature to store a brick of cheese?
The ideal temperature for storing most bricks of cheese is between 35°F and 45°F (2°C and 7°C). This temperature range slows down the aging process, inhibits the growth of unwanted mold, and helps maintain the cheese’s flavor and texture. Storing cheese outside of this range can lead to spoilage, drying out, or the development of undesirable flavors.
Ensure your refrigerator is properly calibrated and check the temperature regularly. Avoid storing cheese in the refrigerator door, as this area tends to fluctuate in temperature more than the interior shelves. A dedicated cheese drawer or a crisper drawer can provide a more stable environment for optimal storage.
What is the best wrapping method to keep my cheese fresh?
After opening a brick of cheese, the best wrapping method involves using cheese paper. Cheese paper is specifically designed to allow the cheese to breathe while maintaining a humid environment. Wrap the cheese tightly in the paper, ensuring all surfaces are covered, and then secure it with tape or a rubber band.
If cheese paper isn’t available, parchment paper or wax paper can be used as a substitute. Avoid using plastic wrap directly against the cheese, as it can trap moisture and lead to a slimy texture or mold growth. For extra protection, place the wrapped cheese in a loosely sealed plastic bag or container. Remember to re-wrap the cheese each time after cutting off a portion.
How long can I store a brick of cheese in the refrigerator?
The shelf life of a brick of cheese in the refrigerator depends on the type of cheese. Hard cheeses like cheddar or Parmesan can last for several weeks, even a month or two, if stored properly. Semi-hard cheeses like Gouda or Monterey Jack typically last for two to three weeks.
Softer cheeses, such as Brie or Camembert, have a shorter shelf life, generally lasting about one to two weeks. Always check for signs of spoilage, such as off-odors, changes in texture, or excessive mold growth. When in doubt, it’s best to discard the cheese to avoid potential foodborne illnesses. Consume opened cheese as soon as possible for the best flavor and texture.
Can I freeze a brick of cheese?
While freezing cheese is possible, it’s generally not recommended, especially for softer varieties. Freezing alters the texture of cheese, making it crumbly and less smooth. This is because the water content in the cheese expands when frozen, disrupting its structure. Harder cheeses tolerate freezing better than soft cheeses, but the texture will still be affected.
If you must freeze cheese, wrap it tightly in plastic wrap, then place it in a freezer bag, removing as much air as possible. Use the frozen cheese for cooking purposes rather than eating it directly, as the change in texture will be less noticeable when melted. Thaw the cheese in the refrigerator overnight for best results. Expect some moisture separation after thawing.
What if mold appears on my brick of cheese?
If mold appears on a hard cheese like cheddar or Parmesan, it’s usually safe to cut off the moldy portion and consume the rest. Cut at least one inch around and below the mold spot, being careful not to drag the knife through the mold. Re-wrap the cheese tightly after removing the mold.
However, if mold appears on soft cheeses like Brie, Camembert, or cream cheese, it’s best to discard the entire brick. These cheeses have a higher moisture content, which allows the mold to penetrate deeper into the cheese. Ingesting moldy soft cheese can potentially cause illness, so it’s not worth the risk.
How do I prevent my cheese from drying out in the refrigerator?
To prevent your cheese from drying out, ensure it’s properly wrapped. Cheese paper is ideal as it allows the cheese to breathe while maintaining some humidity. If using plastic wrap, try wrapping the cheese loosely, then placing it in a loosely sealed plastic bag or container to prevent excessive drying.
Another trick is to slightly dampen a clean cloth or paper towel and wrap it around the cheese before placing it in a container. The moisture from the cloth will help keep the cheese hydrated. Change the cloth every few days to prevent mold growth. Avoid storing cheese near the refrigerator’s vent, as this area can be excessively dry.
What are some signs that my cheese has gone bad?
Several signs indicate that your cheese has gone bad and should be discarded. One of the most obvious signs is a strong, ammonia-like smell, indicating excessive bacterial activity. Another sign is a change in texture, such as a slimy or overly hard surface, or excessive mold growth beyond just a few spots on hard cheeses.
Also, look for changes in color or appearance that are not typical for the cheese type. If the cheese has an off-flavor, even after cutting off any moldy parts, it’s best to err on the side of caution and throw it away. Trust your senses – if something seems off, it probably is.
