We all love cheese, don’t we? Whether it’s on top of a decadent pizza, in a gooey grilled cheese sandwich, or paired with a glass of wine, cheese is a versatile ingredient that can really elevate any dish. However, one of the biggest questions that often arises when it comes to this dairy treat is how long does a block of cheese last. After all, no one wants to suffer from food poisoning or waste precious cheese by throwing it out too soon.
The truth is, the lifespan of a block of cheese can vary greatly depending on the type of cheese, how it’s stored, and whether or not it’s opened. Harder cheeses such as cheddar or parmesan tend to last much longer than soft cheeses like brie or feta. Additionally, cheese that’s been opened will spoil quicker than unopened cheese, as bacteria can quickly start to grow and spread once the seal has been broken.
So, how long can you expect your block of cheese to last? In general, if you’ve got a hard cheese that’s been unopened and stored properly in the fridge, it could last anywhere from 2-6 months. However, if you’ve got a softer cheese or one that’s been opened, you’ll want to aim for a maximum of 1-2 weeks. Keep in mind that these are just general guidelines and it’s always best to use your judgement. If your cheese starts to look or smell funky, it’s better to err on the side of caution and toss it out.
Factors affecting the shelf life of cheese
Cheese is a delicious, versatile dairy product that can add flavor and depth to many dishes. However, like all perishable food items, cheese does have a limited shelf life. The length of time that cheese will maintain its quality and safety depends on several different factors, including:
- The type of cheese
- The production process
- The storage conditions
- The age of the cheese
- The packaging
Let’s take a closer look at each of these factors:
| Factor | Explanation |
|---|---|
| The type of cheese | Different types of cheese have different shelf lives. Soft cheeses like brie or feta will usually only last a few days, while hard, aged cheeses like cheddar or gouda can last for several months. |
| The production process | The way that cheese is made can have an impact on its shelf life. For example, some types of cheese are washed or rubbed with different substances during production, which can affect how long they will last. |
| The storage conditions | Cheese should always be stored properly to maximize its shelf life. Ideally, cheese should be kept in a cool, dark place with moderate humidity, such as a cheese cave or a refrigerator. If cheese is exposed to too much heat or light, it can spoil more quickly. |
| The age of the cheese | Cheese that is older will usually have a stronger flavor, but it may also be more prone to spoilage. This is because as cheese ages, the bacteria in it continue to break down the proteins and fats, which can eventually cause it to go bad. |
| The packaging | The way that cheese is packaged can also affect its shelf life. Vacuum-sealed cheese will usually last longer than cheese that has been wrapped in plastic or paper, as the vacuum sealing removes oxygen, which can cause spoilage. |
By taking these factors into account, you can make sure that you are storing and consuming your cheese in the safest and most delicious way possible.
Types of Cheese with Longer Shelf Life
Cheese is a delicious and versatile food that can be enjoyed in various ways. However, not all cheese types have a long shelf life. Some cheeses spoil quickly, while others can last for months if stored correctly. In this article, we will explore the types of cheese with longer shelf life, so you can enjoy them for longer.

Signs of Spoilage in Cheese
Cheese is one of the most beloved and versatile foods in the world. It comes in many different types, from the hard Parmigiano-Reggiano to the soft and creamy Brie. But like all food items, cheese has a shelf life. If not stored properly, cheese can spoil and cause foodborne illnesses. Here are some signs of spoilage in cheese to look out for:
- Discoloration – Cheese should maintain its original color, and any yellowing or darkening could indicate bacterial growth.
- Mold – While some types of cheese, such as blue cheese and Roquefort, have mold in them, any other mold on the surface of the cheese is not safe to eat.
- Slimy Texture – Cheese should be firm to the touch, not slimy or sticky. This could indicate bacterial growth.
If you notice any of these signs, it is best to discard the cheese to prevent foodborne illnesses. It’s important to note that some types of cheeses, such as hard cheeses like cheddar, can be salvaged if the affected area is cut off. However, it’s still important to be cautious.
When it comes to storing cheese, it’s best to keep it in a cool and dry place, such as the fridge. Avoid wrapping it too tightly in plastic, as this can cause condensation and lead to mold growth. Instead, store cheese in a cheese paper or cheese cloth. This material allows the cheese to breathe and prevents mold from forming on the surface.
| Cheese Type | Refrigerator Shelf Life (Unopened) | Freezer Shelf Life (Unopened) |
|---|---|---|
| Hard Cheese (e.g. cheddar, Parmesan) | 6 months | 6-8 months |
| Semi-hard Cheese (e.g. Gouda, Swiss) | 3-4 weeks | 3-6 months |
| Soft Cheese (e.g. Brie, Camembert) | 1-2 weeks | Not recommended |
Remember to always use your senses – sight, smell, and touch – to determine if the cheese is still safe to eat. If you’re unsure, it’s best to err on the side of caution and discard it.
Can Molded Cheese be Saved?
One of the most common questions when it comes to cheese is whether it can still be consumed when it starts to mold. The answer is not always straightforward as it depends on certain factors such as the type of cheese, the age of the cheese, and where the mold is growing. Here are some things to keep in mind when dealing with molded cheese:
- Soft and fresh cheese such as Brie, Camembert, or goat cheese should not be consumed if they are moldy. The mold could be growing throughout the cheese, making it unsafe to eat, even if you cut off the visible mold.
- Hard cheese such as cheddar, Parmesan, or Swiss cheese, can usually be saved if the mold is only growing on the surface. Cut off at least an inch of cheese around and below the moldy spot, and the rest of the cheese should be safe to consume.
- Blue cheese such as Roquefort or Gorgonzola has mold veins throughout the cheese, so it might be possible to save it if the moldy part is only on the surface. Cut off an inch of cheese around and below the mold, and if the rest of the cheese looks and smells normal, it should be safe to eat.
How to Prevent Cheese from Molding?
The best way to prevent cheese from molding is to store it properly. Cheese should be kept in the refrigerator at 40°F or below in airtight packaging. If the cheese comes in a resealable package, use it to store the cheese. Otherwise, wrap it tightly in plastic wrap, aluminum foil or cheese paper, and place it in a ziplock bag. Avoid directly exposing the cheese to air, as it can promote mold growth. Also, make sure to use clean utensils while handling the cheese and don’t let it sit out for too long.
When to Discard Cheese?
If the cheese is showing signs of spoilage or has an off smell, it’s better to err on the side of caution and discard it rather than risk food poisoning. Also, cheese that has been left at room temperature for more than two hours should be thrown away, as bacteria can grow rapidly at room temperature. Always check the expiration date and use-by date on the packaging before consuming the cheese to ensure that it’s still safe to eat.
How Long Does Cheese Last?
It’s important to remember that cheese is a perishable food, and its shelf life depends on various factors such as the type of cheese, its age, and how it’s stored. Here’s a general guideline for how long cheese lasts:
| Type of cheese | How long it lasts |
|---|---|
| Fresh cheese (ricotta, feta, goat cheese) | 1-2 weeks |
| Semi-soft cheese (Brie, Camembert, Havarti) | 2-3 weeks |
| Hard cheese (cheddar, Parmesan, Swiss) | 3-4 weeks (opened), 6 months (unopened) |
| Blue cheese (Roquefort, Gorgonzola) | 2-3 weeks |
Remember to check the expiration date and the condition of the cheese frequently to ensure it’s safe to consume. When in doubt, it’s better to discard the cheese than risk getting sick.
How to Properly Wrap Cheese for Storage
When it comes to cheese storage, proper wrapping is critical to prevent premature spoilage and maintain the cheese’s flavor and texture. Here are some tips on how to properly wrap cheese for storage:
- Use wax paper or cheese wrap: The ideal method for wrapping cheese is wax paper or cheese wrap. Both allow the cheese to breathe while protecting it from moisture and bacteria. Avoid using plastic wrap as it traps moisture and can cause mold to grow faster.
- Cover the cheese completely: When wrapping cheese, make sure to cover it completely, including the sides and bottom, to prevent air and moisture from entering. This will help preserve the cheese’s flavor and texture for a longer period.
- Avoid using aluminum foil: While aluminum foil may seem like a good choice for storing cheese, it can cause the cheese to sweat and may transfer an off-flavor to the cheese.
Aside from using the right wrapping material and technique, it’s also important to know how long different types of cheese can last in the fridge:
Fresh Cheeses: These are cheeses like ricotta, cream cheese, and goat cheese. They are best consumed within 1-2 weeks of purchase.
Semi-Soft Cheeses: These are cheeses like brie, camembert, and havarti. They can last up to 3 weeks in the refrigerator if properly stored.
Hard Cheeses: These are cheeses like cheddar, parmesan, and gouda. They can last up to 6 months in the refrigerator if stored correctly.
Blue Cheeses: These are cheeses like Roquefort and gorgonzola. They can last up to a month in the refrigerator if stored properly.
| Type of Cheese | Storage Time (Refrigerated) |
|---|---|
| Fresh Cheeses (ricotta, cream cheese, goat cheese) | 1-2 weeks |
| Semi-Soft Cheeses (brie, camembert, havarti) | Up to 3 weeks |
| Hard Cheeses (cheddar, parmesan, gouda) | Up to 6 months |
| Blue Cheeses (Roquefort, gorgonzola) | Up to 1 month |
Remember to always wrap your cheese properly and store it in the right place. Cheese should be stored in the coolest part of the refrigerator, between 34-38°F. With proper storage, you can extend the life of your cheese and ensure its flavor and texture are at their best when you’re ready to enjoy it.
The impact of temperature on cheese shelf life
Temperature plays a crucial role in determining the shelf life of cheese. The right or wrong temperature can either extend or decrease the life of the cheese. Generally, cheese should be stored at temperatures ranging from 35°F to 45°F (2°C to 7°C). Here is an in-depth explanation of the impact of temperature on cheese shelf life:
- Low Temperature: Storing cheese at a low temperature of around 35°F to 40°F (2°C to 4°C) can prolong the life of hard cheeses, such as cheddar, parmesan, and gouda, by up to 6 months. However, lower temperatures can also increase the moisture content of soft, creamy cheese, causing them to spoil faster.
- Room Temperature: Leaving cheese at room temperature is generally not the best practice as the cheese can spoil or become rancid. Soft cheese can be left at room temperature for a maximum of 2 hours, and hard cheese for up to 4 hours. Room temperature should be avoided at all costs as it accelerates the growth of bacteria and encourages the growth of mold.
- High Temperature: Cheese should never be left in temperatures exceeding 50°F (10°C) as it can cause the cheese to become crumbly and lose its flavor. Higher temperatures allow bacteria to multiply at a faster rate, shortening the life of the cheese significantly. Cheese that has been left in warm temperatures can be dangerous and lead to food poisoning.
It’s important to note that humidity is just as important as temperature when it comes to preserving cheese. Cheese should be kept in a damp or moist environment, so it doesn’t dry out or become rancid. Wrap your cheese in paper or cheese cloth, then place it in a plastic bag with small air holes to prevent moisture from accumulating.
The impact of temperature on cheese shelf life: A comparison table
| Type of Cheese | Recommended Temperature | Shelf Life (in months) |
|---|---|---|
| Hard Cheese (cheddar, parmesan, gouda) | 35°F to 40°F (2°C to 4°C) | Up to 6 months |
| Soft Cheese (brie, camembert, feta) | 41°F to 50°F (5°C to 10°C) | 1 to 2 weeks |
| Blue Cheese (roquefort, stilton, gorgonzola) | 35°F to 40°F (2°C to 4°C) | 3 to 6 months |
By following the recommended temperature guidelines and storing your cheese properly, you can make sure it lasts the maximum amount of time possible without compromising the flavor and safety of the cheese.
The Role of Moisture in Cheese Shelf Life
When it comes to the shelf life of cheese, one of the key factors to consider is moisture content. This is because moisture impacts both the texture and the flavor of the cheese, as well as its susceptibility to spoilage.
- Cheeses with higher moisture content are typically softer and creamier, with a more delicate flavor. Examples include fresh cheeses like ricotta, mozzarella, and feta, as well as bloomy rind cheeses like brie and camembert.
- Cheeses with lower moisture content tend to be harder and more crumbly, with a sharper, more robust flavor. Examples include aged cheeses such as cheddar, Parmesan, and Gouda.
The amount of moisture in cheese can also influence its susceptibility to mold and bacterial growth. Cheeses with higher moisture content are more prone to spoilage, as the moisture provides an ideal environment for bacteria and other microorganisms to thrive. This means that softer cheeses tend to have a shorter shelf life than harder cheeses, and should be consumed within a few days of opening.
On the other hand, harder cheeses can often last for several weeks or even months, as the lower moisture content makes them less vulnerable to spoilage.
| Cheese Type | Moisture Content | Shelf Life (Unopened) | Shelf Life (Opened) |
|---|---|---|---|
| Fresh Cheese (Ricotta, Mozzarella, Feta) | High (50-80%) | Up to 2 weeks | 3-4 days |
| Bloomy Rind Cheese (Brie, Camembert) | High (50-75%) | 1-2 weeks | 3-4 days |
| Semi-Soft Cheese (Havarti, Monterey Jack) | Medium (40-50%) | 3-4 weeks | 1-2 weeks |
| Hard Cheese (Cheddar, Parmesan, Gouda) | Low (30-40%) | Several months | 3-4 weeks |
So if you want to extend the shelf life of your cheese, look for options with lower moisture content, and make sure to store them properly in a cool, dry place.
How to Determine if Cheese is Still Safe to Eat
Cheese is a delicious and versatile food that can be enjoyed in a variety of ways. Whether it’s sliced on a sandwich, grated on pasta, or melted on a pizza, cheese adds flavor and texture to many dishes.
However, cheese is a perishable food and can spoil over time. It is important to know how to determine if cheese is still safe to eat to avoid foodborne illness.
- Check the expiration date – Cheese typically has a “sell by” or “use by” date on the packaging. This is a good starting point to determine if the cheese is still safe to eat. However, it is important to note that this date is only a guideline and the cheese may still be edible after this date.
- Inspect the cheese – Look at the cheese to see if there are any signs of mold or discoloration. If there are any visible signs of mold, the cheese should be discarded. Discoloration can also indicate spoilage.
- Smell the cheese – Give the cheese a sniff to see if there are any off odors. Cheese that smells sour, ammonia-like, or has a strong odor should not be consumed.
If the cheese passes these tests, it should be safe to eat. However, it is important to note that certain types of cheese, such as soft cheeses like brie or feta, may have a shorter shelf life and may spoil more quickly than harder, aged cheeses.
Here is a guide for how long different types of cheese can last:
| Cheese Type | Refrigerator (Opened) | Refrigerator (Unopened) | Freezer (Opened) | Freezer (Unopened) |
|---|---|---|---|---|
| Hard, aged cheeses (e.g. cheddar, parmesan) | 3-4 weeks | 6 months | 6 months | 6-8 months |
| Soft, fresh cheeses (e.g. brie, feta) | 1 week | 1-2 weeks | Not recommended | Not recommended |
| Processed cheese | 4 weeks | 8 months | Not recommended | Not recommended |
Proper storage is also important for keeping cheese fresh. Cheese should be kept in the refrigerator at or below 40°F, preferably in the original packaging or wrapped in cheesecloth or parchment paper. Avoid storing cheese in plastic wrap or bags, as this can trap moisture and promote mold growth.
By following these guidelines, you can enjoy delicious cheese while keeping your family safe from foodborne illness.
