Cheese, a beloved culinary staple across cultures, comes in a dazzling array of flavors, textures, and aromas. From the sharp tang of aged cheddar to the creamy smoothness of brie, there’s a cheese to delight every palate. However, cheese can be a perishable food, and knowing how to properly store it is crucial to prevent spoilage, maintain its quality, and enjoy it for longer. This guide provides a detailed exploration of effective cheese storage techniques, catering to different types of cheese and storage conditions.
Understanding Cheese Spoilage
Before diving into storage methods, it’s important to understand why cheese spoils. Spoilage is primarily caused by the growth of molds and bacteria. Mold growth is often visible and can alter the taste and texture of the cheese. While some molds are intentionally cultivated in cheeses like blue cheese, others are undesirable and indicate spoilage. Bacterial growth, on the other hand, may not always be visible but can lead to off-flavors, slimy textures, and ultimately, make the cheese unsafe to eat. Exposure to air, temperature fluctuations, and moisture contribute significantly to both mold and bacterial growth.
Furthermore, the type of cheese plays a crucial role in its shelf life. Hard cheeses like Parmesan and cheddar, with their low moisture content, tend to last longer than soft cheeses like brie and ricotta, which are more prone to spoilage due to their higher moisture content.
General Cheese Storage Principles
Regardless of the specific type of cheese, certain fundamental principles apply to all cheese storage. Adhering to these principles significantly extends the life of your cheese and preserves its flavor.
Temperature Control
Temperature is perhaps 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 temperature range slows down the growth of spoilage microorganisms without freezing the cheese, which can alter its texture.
Your refrigerator’s crisper drawer often provides a more stable and slightly warmer environment than the main compartment, making it an ideal location for storing cheese. However, avoid storing cheese near the refrigerator door, where temperature fluctuations are more pronounced.
Humidity Management
Maintaining adequate humidity is also essential. Cheese needs a certain level of humidity to prevent it from drying out and cracking. However, excessive humidity promotes mold growth. Strive for a humidity level of around 70-80%.
Protecting from Air
Exposure to air is a major contributor to cheese spoilage. Air can dry out the cheese, causing it to harden and crack. It also provides a pathway for mold spores and bacteria to contaminate the cheese. Proper wrapping is crucial to minimize air exposure.
Avoiding Cross-Contamination
Cheese can absorb odors from other foods in the refrigerator. To prevent this, store cheese away from strongly scented items like onions, garlic, and leftover meals. Proper wrapping also helps to minimize odor absorption.
Specific Cheese Storage Methods
Different types of cheese require slightly different storage methods to optimize their shelf life and maintain their quality.
Hard Cheeses (Cheddar, Parmesan, Gruyere)
Hard cheeses, with their lower moisture content, generally have a longer shelf life than soft cheeses. However, they still require proper storage to prevent them from drying out.
Wrapping Hard Cheeses
The best way to wrap hard cheeses is to use parchment paper or cheese paper. These materials allow the cheese to breathe while still providing a barrier against air. Wrap the cheese tightly in the paper and then place it in a resealable plastic bag or container. This double layer of protection helps to maintain humidity and prevent drying.
Avoid using plastic wrap directly on hard cheeses for extended periods, as it can trap moisture and lead to a slimy surface. If you must use plastic wrap, change it frequently.
Storing Hard Cheeses
Store wrapped hard cheeses in the crisper drawer of your refrigerator. Check the cheese regularly for mold growth. If mold appears, cut away at least 1 inch around the mold spot. The remaining cheese is usually safe to eat, as hard cheeses are less susceptible to mold penetration.
Semi-Hard Cheeses (Gouda, Monterey Jack, Edam)
Semi-hard cheeses fall between hard and soft cheeses in terms of moisture content and storage requirements.
Wrapping Semi-Hard Cheeses
Like hard cheeses, semi-hard cheeses benefit from being wrapped in parchment paper or cheese paper and then placed in a resealable plastic bag or container. This method provides a balance between breathability and protection from air and moisture.
Storing Semi-Hard Cheeses
Store wrapped semi-hard cheeses in the crisper drawer of your refrigerator. Monitor the cheese for mold growth and remove any mold spots as described for hard cheeses.
Soft Cheeses (Brie, Camembert, Feta, Ricotta)
Soft cheeses are more delicate and require more careful storage due to their high moisture content.
Wrapping Soft Cheeses
Soft cheeses are often sold in their own containers or wrapped in plastic. If the original packaging is intact, it’s best to store the cheese in that packaging. However, if the packaging is damaged or you’ve opened the cheese, rewrap it carefully.
For soft cheeses like brie and Camembert, wrap them in parchment paper or cheese paper and then place them back in their original wooden container or a similar container. This helps to maintain their shape and prevent them from drying out.
For feta cheese, which is typically stored in brine, ensure that the cheese is fully submerged in the brine. Add more brine if necessary (a simple brine solution can be made with water and salt).
For ricotta cheese, store it in an airtight container in the refrigerator.
Storing Soft Cheeses
Store soft cheeses in the coldest part of your refrigerator, typically on a lower shelf. Consume soft cheeses as soon as possible, as they have a shorter shelf life than hard cheeses.
Blue Cheeses (Gorgonzola, Stilton, Roquefort)
Blue cheeses have a unique flavor and aroma due to the presence of specific molds. Proper storage is crucial to maintain their characteristic flavor and prevent the growth of undesirable molds.
Wrapping Blue Cheeses
Wrap blue cheeses in foil or plastic wrap. These materials help to contain the strong aroma of blue cheese and prevent it from affecting other foods in your refrigerator.
Storing Blue Cheeses
Store wrapped blue cheeses in a separate container in the refrigerator. This helps to prevent the cheese from contaminating other foods with its mold spores.
Fresh Cheeses (Mozzarella, Chevre)
Fresh cheeses, like mozzarella and chevre, are high in moisture and have a very short shelf life.
Wrapping Fresh Cheeses
Mozzarella is often stored in water or whey. Keep the mozzarella submerged in its liquid and store it in an airtight container in the refrigerator. Change the water or whey every few days to keep it fresh.
Chevre, or goat cheese, can be stored in its original packaging or wrapped in plastic wrap.
Storing Fresh Cheeses
Store fresh cheeses in the coldest part of your refrigerator. Consume fresh cheeses within a few days of purchase.
Signs of Spoilage
Even with proper storage, cheese can eventually spoil. It’s important to be able to recognize the signs of spoilage to avoid consuming unsafe cheese.
Visible Mold
The most obvious sign of spoilage is the presence of mold. As mentioned earlier, some molds are desirable in certain cheeses, but other molds are not. If you see mold that is not characteristic of the cheese, it’s likely a sign of spoilage.
Off-Odor
Spoiled cheese may have an unpleasant or ammonia-like odor. This is a sign of bacterial growth and indicates that the cheese should be discarded.
Slimy Texture
A slimy texture on the surface of the cheese is another sign of bacterial growth. This is especially common in soft cheeses.
Sour or Bitter Taste
If the cheese tastes sour or bitter, it’s likely spoiled.
Tips for Extending Cheese Shelf Life
In addition to proper storage methods, the following tips can help to extend the shelf life of your cheese:
- Buy cheese in smaller quantities: Purchase only the amount of cheese that you can consume within a reasonable timeframe.
- Don’t open cheese until you’re ready to use it: Keep cheese in its original packaging until you’re ready to eat it.
- Handle cheese with clean hands: Avoid touching the cheese with dirty hands, as this can introduce bacteria.
- Use separate cutting boards and knives: Use separate cutting boards and knives for cheese to prevent cross-contamination.
- Consider freezing cheese (with caveats): Freezing can extend the shelf life of hard cheeses, but it can also alter their texture, making them more crumbly. Soft cheeses generally do not freeze well. If you do freeze cheese, wrap it tightly in plastic wrap and then place it in a freezer bag. Thaw the cheese in the refrigerator before using it.
- Vacuum sealing: Vacuum sealing is an excellent option for long-term cheese storage, especially for hard cheeses. It removes air and prevents oxidation and mold growth.
Cheese Storage Container Options
Selecting the right container significantly impacts cheese preservation.
- Cheese Paper/Parchment Paper: As emphasized, these allow breathability while providing a barrier.
- Reusable Cheese Wraps: Often beeswax-based, these are eco-friendly and offer good protection.
- Airtight Containers: Suitable for hard cheeses wrapped in paper or soft cheeses in their own liquid (like mozzarella).
- Specialized Cheese Storage Containers: Some containers are designed with ventilation and humidity control features specifically for cheese.
Serving Cheese Correctly
The way you serve cheese also affects how long it stays fresh.
- Bring cheese to room temperature before serving: This allows the flavors to fully develop. Take out only what you plan to serve.
- Cut cheese just before serving: This minimizes exposure to air.
- Avoid leaving cheese out at room temperature for extended periods: Bacteria multiply rapidly at room temperature.
By following these guidelines, you can enjoy your favorite cheeses for longer while preserving their quality and flavor. Proper cheese storage is not only about preventing spoilage but also about respecting the craftsmanship and unique characteristics of each cheese.
What are the best types of cheese to buy if I want them to last a long time?
Hard cheeses like Parmesan, cheddar, and aged Gouda generally last the longest due to their lower moisture content. The drier the cheese, the less susceptible it is to mold growth and bacterial spoilage. When selecting these cheeses, look for well-sealed packaging or ask for a freshly cut piece from the cheese counter, ensuring it’s handled with clean tools and wrapped properly.
Soft cheeses such as Brie, Camembert, and fresh mozzarella have a much shorter shelf life because of their higher moisture content. These cheeses are more prone to developing mold and bacteria, so it’s best to purchase them closer to the time you intend to use them. Consider buying smaller quantities to avoid waste.
How should I properly store cheese in my refrigerator to maximize its lifespan?
Proper storage is key to extending the life of your cheese. Wrap cheese in parchment paper or wax paper, then loosely in plastic wrap. This allows the cheese to breathe while still protecting it from drying out and absorbing unwanted odors from the fridge. For softer cheeses, store them in their original packaging or a sealed container with a little whey to maintain moisture.
Ensure the temperature in your refrigerator is consistently between 35-45°F (2-7°C). Place cheese in the vegetable crisper drawer or a designated cheese drawer, if you have one, as these areas typically have more stable temperatures. Avoid storing cheese in the door of the refrigerator, where temperatures fluctuate more frequently.
Can I freeze cheese, and if so, what types are best suited for freezing?
Freezing cheese can extend its shelf life significantly, but it can also affect the texture and flavor. Hard cheeses like cheddar and Parmesan generally freeze well, though they may become slightly crumbly upon thawing. Shredding the cheese before freezing can make it easier to use later.
Soft cheeses, such as Brie and cream cheese, are not recommended for freezing as they can become watery and lose their creamy texture. If you must freeze soft cheese, be aware that it may be best suited for cooked dishes rather than eating fresh. Always wrap cheese tightly in plastic wrap and then place it in a freezer bag to prevent freezer burn.
What are the signs that cheese has gone bad, and is it always unsafe to eat moldy cheese?
Visible mold, an ammonia-like smell, or a slimy texture are clear indicators that cheese has gone bad. Discard cheese that exhibits these signs, as it may contain harmful bacteria or toxins. The color can also change, and it may harden.
For hard cheeses, if you find small spots of mold, you can often cut away at least 1 inch around the mold spot and safely consume the rest of the cheese. However, soft cheeses should be discarded entirely if mold is present. Always use your best judgment and err on the side of caution when dealing with potentially spoiled cheese.
How does the type of packaging affect the lifespan of cheese?
The packaging plays a crucial role in preserving cheese. Vacuum-sealed packaging is excellent for extending the shelf life of hard cheeses, as it prevents exposure to air and moisture. If buying from a cheese counter, ask the cheesemonger to wrap the cheese in cheese paper, which allows it to breathe while protecting it.
Avoid storing cheese tightly wrapped in only plastic wrap, as this can trap moisture and promote mold growth. For pre-packaged cheeses, follow the manufacturer’s instructions regarding storage after opening. Re-sealable containers can be helpful for maintaining freshness.
Is it better to buy cheese pre-sliced or as a whole block to make it last longer?
Buying cheese as a whole block is generally better for extending its shelf life compared to pre-sliced or shredded cheese. The larger surface area exposed in sliced or shredded cheese makes it more vulnerable to drying out and developing mold. A whole block retains its moisture and protective rind (if applicable) for longer.
If you frequently use cheese in small quantities, consider cutting off only what you need from the block and re-wrapping the remaining portion properly. Pre-sliced or shredded cheese is convenient but should be consumed more quickly to prevent spoilage. Choose based on your consumption habits and prioritize freshness.
How can I revive cheese that has become slightly dry or hard?
If your cheese has become slightly dry or hard, you can try reviving it by wrapping it in a damp cheesecloth or paper towel and placing it in a sealed container in the refrigerator. The moisture will help rehydrate the cheese. Leave it for a few hours or overnight.
Another technique is to rub the cut surface of the cheese with a bit of olive oil. This can help prevent further drying and improve the texture. These methods work best for hard or semi-hard cheeses that haven’t completely dried out. If the cheese is excessively hard or cracked, it might be better suited for cooking rather than eating as is.
