Cheese is one of the most beloved dairy foods around the world, celebrated for its diverse flavors, textures, and culinary versatility. However, it’s essential to understand how long refrigerated cheese lasts to ensure that you enjoy its taste at its best while keeping your health in mind. In this detailed article, we’ll explore the various factors affecting cheese shelf life, types of cheese, and practical tips for storing cheese to maximize its freshness.
The Basics of Cheese Preservation
Cheese, as a dairy product, is perishable and comes with varying shelf lives depending on its type and how it’s stored. Various factors affect the longevity of cheese, such as:
- Type of Cheese: Hard cheeses generally last longer than soft cheeses.
- Storage Conditions: Cheese must be stored properly to minimize spoilage.
Understanding these factors can help you decide whether that block of cheddar in your fridge is still good or if it’s time to toss it out.
Factors Influencing Cheese Longevity
Several factors influence how long cheese can be safely consumed after being refrigerated:
1. Cheese Type
Each cheese variety possesses unique characteristics affecting its shelf life:
- Hard Cheeses: Cheeses like Parmesan, Pecorino, and aged Gouda can last several months in the refrigerator due to their low moisture content.
- Soft Cheeses: Brie, Camembert, and cream cheese typically last between one to two weeks after opening.
2. Storage Method
Proper storage is crucial for extending the life of cheese. The best practices include:
A. Wrapping
Use wax paper, parchment paper, or specialized cheese paper to wrap the cheese. Avoid plastic wrap, as it can trap moisture and promote mold growth.
B. Temperature
Keep your refrigerator at or below 40°F (4°C). Storing cheese in the vegetable crisper can help maintain optimal humidity and temperature.
C. Air Exposure
Limit air exposure by properly wrapping cheese. Oxygen can cause spoilage and flavor loss.
How Long Different Types of Cheese Last
Thus far, we have mentioned that different cheese types have varying shelf lives, but let’s break it down more comprehensively:
| Type of Cheese | Approximate Shelf Life in the Refrigerator | Signs of Spoilage |
|---|---|---|
| Fresh Cheese (e.g., ricotta, goat cheese) | 1 week | Off smell, discoloration, excessive moisture |
| Soft Cheese (e.g., Brie, Camembert) | 1-2 weeks | Discoloration, strong odor, slimy texture |
| Semi-Hard Cheese (e.g., Cheddar, Gouda) | 3-4 weeks | Mold spots, off odor, dryness |
| Hard Cheese (e.g., Parmesan, aged Gouda) | 6 months to a year | Surface mold, very hard texture |
| Processed Cheese (e.g., American cheese, cheese spreads) | 2-3 months | Changes in texture, flavor, or smell |
This table serves as a helpful reference to understand how long various cheese types can last once placed in a refrigerator.
How to Store Refrigerated Cheese Properly
Safe storage techniques play a significant role in extending the shelf life of cheese. Here are some essential tips:
1. Use the Right Packaging
Choose proper packaging materials. For instance, using cheese paper allows the cheese to breathe while maintaining moisture. You can also wrap cheese in wax paper before placing it in a resealable bag.
2. Keep Cheese in the Right Spot
Store cheese in a climate-controlled area of the refrigerator, such as the cheese drawer or vegetable crisper. Avoid storing it in the refrigerator door, where temperatures fluctuate.
3. Label Your Cheese
Since different cheeses have varying shelf lives, label each cheese with the date you opened it. This practice provides a clear visual of its remaining freshness.
Recognizing Spoilage in Cheese
Understanding the signs of spoilage helps prevent consuming spoiled cheese that could lead to foodborne illness. Here are some indicators to look out for:
1. Unpleasant Odor
If cheese emits a smell that is significantly stronger or different from its normal aroma, it may be going bad.
2. Visual Signs
Check for discoloration, especially if the cheese has turned a different hue or has spots of mold (unless it’s a blue cheese, where mold is part of the process).
3. Texture Change
If cheese becomes excessively hard, dry, or slimy, these changes may signify spoilage.
How to Extend the Life of Refrigerated Cheese
If you want to prolong the shelf life of your cheese even further, consider implementing these strategies:
1. Freeze Cheese for Longer Storage
While freezing can change the texture of some cheeses, it is a viable option for those you may not use soon. Wrap cheese tightly in plastic wrap or aluminum foil, then place it in a freezer-safe bag.
2. Avoid Repeated Exposure
Try to minimize how often you take your cheese in and out of the refrigerator. Each time cheese is exposed to air, the risk of spoilage increases.

Keep this guide handy, and let it serve as a roadmap toward cheese enjoyment and safety.
How long does refrigerated cheese last?
Refrigerated cheese can last anywhere from a few days to several months, depending on the type of cheese and how it is stored. Soft cheeses like ricotta or cream cheese generally have a shorter shelf life, typically lasting about 1 to 2 weeks after opening. In contrast, hard cheeses such as cheddar or parmesan can be kept for several months, and sometimes even longer, if properly wrapped and stored in the fridge.
To maximize the shelf life of your cheese, always keep it tightly wrapped in its original packaging or store it in a cheese-specific container. Ensure that you minimize the exposure to air, as this can lead to spoilage. Additionally, pay attention to expiration or ‘best by’ dates on the packaging as a guideline for freshness.
How can I tell if cheese has gone bad?
There are several signs to look for when trying to determine if cheese has gone bad. For hard cheeses, the appearance of mold can be a significant indicator. If you notice small spots of mold not typical for that variety of cheese, it’s often safe to cut away the affected area (about one inch around the mold), as hard cheeses tend to be more resilient. However, if the mold has spread extensively or the cheese has developed an off-smell, it’s best to discard it.
For soft cheeses like cottage cheese or cream cheese, spoilage is typically indicated by a sour smell or a change in texture, such as excessive separation of liquid or a slimy coating. If the cheese tastes sour or develops a visibly altered appearance, it should be discarded to avoid the risk of foodborne illness.
Does unopened cheese last longer than opened cheese?
Yes, unopened cheese typically lasts longer than opened cheese. When cheese is sealed in its packaging, it is better protected from air, moisture, and contaminants that can lead to spoilage. Many types of cheese can be kept in the fridge for several weeks to months when left unopened, especially hard cheeses that have a lower moisture content.
Once opened, cheese becomes more susceptible to spoilage due to exposure to air and pathogens. It’s essential to reseal and refrigerate opened cheese properly. By keeping it wrapped or in a sealed container, you can help extend its shelf life, although it still won’t last as long as when it’s unopened.
What is the best way to store cheese in the refrigerator?
The best way to store cheese in the refrigerator varies depending on the type. For hard cheeses, wrap them in wax paper or parchment paper and then place them in a loose plastic bag or cheese container. This allows the cheese to breathe while still keeping moisture in, preventing it from drying out. Soft cheeses, on the other hand, should be kept in their original packaging if unopened; once opened, store them in an airtight container to maintain moisture.
Additionally, keeping cheese in the less cold sections of the fridge, such as the vegetable drawer, can help preserve its texture and flavor. Avoid storing cheese near strong-smelling foods, as it can absorb odors. Maintaining a stable temperature without frequent fluctuations also contributes to keeping cheese fresh for a longer duration.
Can I freeze cheese to extend its shelf life?
Yes, you can freeze cheese to extend its shelf life, but the texture and flavor may change after thawing. Hard cheeses like cheddar, gouda, or parmesan freeze well and can be grated or sliced before freezing for convenience. When thawed, they may become grainy, which is often acceptable for cooked dishes where texture is not as critical.
However, soft cheeses like cream cheese and ricotta do not freeze as well; they can lose their creamy texture and become crumbly. If you choose to freeze soft cheese, consider using it in cooked recipes post-thaw, where the change in texture is less noticeable. Always wrap cheese tightly in plastic wrap and place it in an airtight container or freezer bag to prevent freezer burn.
Is it safe to eat cheese past its expiration date?
Whether it is safe to eat cheese past its expiration date largely depends on the cheese type and its condition. Hard cheeses can often be consumed after their expiration date, provided they do not show signs of spoilage such as mold, sour smell, or off texture. As long as the cheese has been stored correctly, it can still be perfectly safe and enjoyable even a few weeks past the date.
In contrast, soft cheeses are more perishable and are best consumed before the expiration date. Consuming soft cheese after this date can pose a risk of foodborne illness, especially if mold or spoilage signs are present. Always perform a thorough inspection before consuming older cheese, regardless of its type.
Does cheese need to be kept covered in the refrigerator?
Yes, cheese should always be kept covered in the refrigerator to prevent it from drying out and absorbing odors from other foods. Left uncovered, cheese may develop a hard, dry rind, resulting in a less enjoyable texture and taste. Additionally, exposure to air can promote mold growth and spoilage.
Using appropriate coverings is essential for preserving cheese. Wax paper or parchment paper is ideal for wrapping hard cheeses, followed by a loose plastic bag. For soft cheeses, an airtight container is recommended. Maintaining a proper barrier helps to retain moisture and keeps the cheese fresh for longer periods.
Can I eat cheese with mold on it?
The safety of eating cheese with mold depends on the type of cheese. For hard cheeses, it is generally safe to cut away the mold, removing about an inch around the affected area since the mold rarely penetrates too deeply. However, ensure that the cheese does not have a rancid smell or other signs of spoilage before consuming it.
Soft cheeses with mold, especially those not intended to have mold (like blue cheese), should be discarded if they develop an unacceptable level of mold. Soft cheeses are more likely to be contaminated with pathogens when mold is present. Always use discretion and inspect the cheese carefully before consuming it if mold appears.
