Cheese Longevity: How Long Does Packaged Cheese Last?

Cheese is a dairy product with a long shelf life, but it's important to know how long it lasts to avoid eating spoiled cheese. The shelf life of cheese depends on the type of cheese and how it's stored. For example, hard cheeses like Asiago, Parmesan, and Cheddar can last between two and four months in the fridge if unopened, while soft cheeses like cream cheese, Brie, and mozzarella should be consumed within one to two weeks of being opened. Proper storage is key to maintaining the quality and safety of cheese, such as using porous materials for wrapping and keeping the fridge below 40°F (4°C).

Unopened hard cheeses don't need to be refrigerated

Hard, aged cheeses are pressed under pressure and aged for longer than soft cheeses, resulting in lower moisture content. This makes them less prone to spoilage from bacteria and means they can be stored at room temperature. In fact, refrigeration tends to halt the aging processes of cheese. Cheese is typically aged somewhere in the 50-60°F (10-16°C) range, depending on the variety.

Hard cheeses like Parmigiano Reggiano (also known as Parmesan), Pecorino Romano, Grana Padano, aged Gouda, Provolone, Asiago D'allevo, and Appenzeller can be stored unrefrigerated. In addition, unopened processed cheeses like canned cheese, squeezable cheese, and sealed loaves or blocks of American cheese don't need to be refrigerated either.

However, refrigeration will help hard cheeses last even longer. Unopened blocks of hard cheese can last up to 6 months in the fridge. If you do choose to store hard cheeses at room temperature, it's best to wrap them tightly and store them in an airtight container in a cool, dark place away from direct sources of heat and light.

While unopened hard cheeses don't need to be refrigerated, once they are opened, they should be treated like any other cheese. Hard cheeses that have been opened will last 3-4 weeks in the fridge.

Hard cheeses last 3-4 times longer than soft cheeses

Hard cheeses, such as Asiago, Parmesan, Beaufort, pecorino Romano, and Cheddar, last 3-4 times longer in the fridge than soft cheeses. This is because they contain less moisture and are therefore less prone to spoilage from bacteria. An unopened package of hard cheese can last between two and four months, while an opened package of Parmesan or block of cheddar is good for about six weeks in the fridge. Most hard cheeses will last 3-4 weeks after opening.

Soft cheeses, on the other hand, tend to spoil more quickly and should be consumed within one to two weeks of opening. Examples of soft cheeses include cottage cheese, cream cheese, ricotta, Brie, mozzarella, Neufchâtel, feta, Gorgonzola, and Camembert. These cheeses have a high moisture content, making them more susceptible to bacterial growth and spoilage.

It is worth noting that the shelf life of cheese can vary depending on the quality of the cheese, the storage conditions, and the presence of preservatives. Proper storage methods, such as wrapping cheese in wax, parchment, or cheese paper, can help extend the shelf life of both hard and soft cheeses.

Additionally, while it is possible to freeze cheese, it is generally not recommended as it can alter the taste and texture, especially for soft cheeses.

Soft cheeses last 1-2 weeks in the fridge after opening

Soft cheeses, such as cottage cheese, cream cheese, ricotta, Brie, mozzarella, Neufchâtel, feta, Gorgonzola, and Camembert, tend to spoil faster than hard cheeses because they contain more moisture, which makes them prone to bacterial spoilage. Therefore, soft cheeses should be consumed within 1-2 weeks of opening the package and stored in the fridge.

To ensure the safety of consumption, it is important to inspect soft cheeses for any signs of spoilage, such as mould, an unpleasant odour, or a slimy texture. If any of these indicators are present, it is best to discard the cheese.

Proper storage practices can help extend the shelf life of soft cheeses. It is recommended to store soft cheeses in their original unopened packaging until ready to use. Once opened, transfer the cheese to a tightly sealed container or a Tupperware container with limited airflow to prevent excessive drying. Additionally, maintaining a safe fridge temperature below 40°F (4°C) is crucial to slowing bacterial growth.

Freezing is not recommended for soft cheeses as it can alter their texture and make them grainy, compromising their meltability.

Wrap blocks of cheese in wax, parchment or cheese paper

When storing cheese, it's important to use the right type of wrapping to maintain its quality and prolong its shelf life. Wrapping blocks of cheese in wax, parchment, or cheese paper is an effective way to achieve this.

Wax paper is a versatile and breathable material that helps regulate moisture. It allows just the right amount of air circulation, preventing the cheese from drying out while also protecting it from excess humidity. This makes it ideal for wrapping blocks of cheese that don't come in resealable packaging. Parchment paper, also known as bakery paper, is another suitable option for wrapping cheese. It is grease and moisture-resistant, providing a barrier that helps keep the cheese fresh. Additionally, cheese paper, a specialty paper designed specifically for cheese storage, is an excellent choice. It is usually coated with a thin layer of wax, creating a semi-permeable barrier that regulates moisture and slows down the growth of mould.

To use these papers effectively, wrap the cheese loosely, ensuring it is not too tight. This allows the cheese to breathe and helps maintain optimal humidity levels. After wrapping the cheese in wax, parchment, or cheese paper, it can be stored on the top or middle shelf of the fridge, or in a drawer. It is important to keep the cheese above raw meats, poultry, and fish to avoid contamination.

By following these wrapping and storage methods, you can prolong the life of your cheese and enjoy it at its best.

Store cheese on the top or middle shelf, or in a drawer

When storing cheese in the refrigerator, it is best to place it on the top or middle shelf, or in a drawer. This is to avoid contamination from raw meats, poultry, and fish that are typically stored on the lower shelves.

The refrigerator temperature should be maintained below 40°F (4°C) to ensure food safety and slow down bacterial growth. At higher temperatures, bacteria multiply faster, increasing the risk of spoilage.

Proper wrapping is crucial for cheese storage. Avoid using tight, non-porous materials like plastic wrap, as they can dry out the cheese and harden it. Instead, opt for wax paper, parchment paper, cheese paper, or cheesecloth. These materials allow the cheese to breathe while maintaining moisture.

For soft cheeses, consider using a Tupperware container or plastic jar to limit airflow while still providing some ventilation. Hard cheeses, on the other hand, benefit from being wrapped tightly in wax or parchment paper and then placed in a Ziploc bag to limit airflow and contain odours.

Additionally, it is important to note that different types of cheeses have varying shelf lives. Soft cheeses typically last 1-2 weeks in the fridge after opening, while hard cheeses can last 3-4 weeks. Harder, aged cheeses will last the longest, up to 4-6 months if stored correctly.
