Cheese Storage: How Long Does Sealed Cheese Stay Fresh?

Cheese is a tasty and nutritious treat, but it can be hard to know how long it will last. The shelf life of cheese depends on a few factors, including the type of cheese, how it is stored, and the environment it is stored in. Sealed cheese can last for a few weeks to several months, depending on these variables. So, how long will your sealed cheese last? Let's take a look at the factors that determine its shelf life.

Sealed cheese should be stored at a temperature below 40°F (4°C)

Cheese is a tasty, nutritious, and versatile food product that can be stored for long periods. The length of time cheese lasts depends on the type of cheese and the storage method. Soft cheeses tend to spoil more quickly than hard cheeses due to their higher moisture content, which provides an ideal environment for bacteria to thrive.

To maximise the shelf life of sealed cheese, it should be stored in a refrigerator at a temperature below 40°F (4°C). This will help to prevent the growth of bacteria and maintain the quality and safety of the cheese.

In addition to maintaining the correct temperature, proper storage methods should be followed. Sealed cheese should be stored in the original packaging and kept in a container with an airtight lid. It is important not to open the package until ready to use, as this will help to maximise the shelf life.

By following these storage guidelines, sealed cheese can be safely stored for extended periods, ensuring that it remains fresh and delicious.

Vacuum-sealed cheese can last several months to years

Hard cheeses, such as cheddar, aged Gouda, and Parmigiano Reggiano, have low moisture content, which makes it difficult for bacteria to flourish. This means that vacuum-sealed packages of hard cheese can last for several months to about six months in the refrigerator. Unopened hard cheeses may even be stored without refrigeration, although they will last much longer if they are refrigerated.

Soft cheeses, such as ricotta, feta, and mozzarella, have a higher moisture content, making them more perishable than harder cheeses. Vacuum-sealed soft cheeses will typically last for several months in the refrigerator, although their quality and taste may start to decline after the first week.

To maximize the shelf life of vacuum-sealed cheese, it is important to store it properly. Cheese should be stored in a cool, dry place, ideally below 72 degrees Fahrenheit. It is also important to ensure that the vacuum seal is intact and that the cheese is protected from humidity and direct sunlight.

Additionally, different types of cheese will have varying shelf lives due to their moisture content. For example, relatively dry cheeses like Asiago or Parmesan will last longer than softer, higher-moisture cheeses like mozzarella.

By following proper storage techniques and being mindful of the type of cheese, you can ensure that your vacuum-sealed cheese lasts for several months to years.

Unopened, sealed blocks of hard cheese can last up to 6 months

The specific type of cheese, moisture content, and storage method all influence how long cheese will last. Hard cheeses, such as aged cheddar, aged Gouda, and Parmigiano Reggiano, can be stored in the refrigerator for about four weeks once opened. Unopened packages of these cheeses will last for a longer period, typically about six months, according to experts at the USDA.

To maximise the shelf life of unopened hard cheese, it is important to maintain proper storage conditions. This includes keeping the cheese refrigerated at all times and maintaining a temperature of below 40°F (4°C). At higher temperatures, the rate of bacterial growth increases significantly, raising the risk of spoilage.

Additionally, the way you wrap the cheese makes a difference. It is recommended to remove the cheese from its plastic packaging and wrap it loosely in cheese paper or wax paper before placing it in an airtight container. Avoid using tight, non-porous materials like plastic wrap, as they can dry out the cheese.

By following these storage guidelines, you can ensure that your unopened, sealed blocks of hard cheese remain edible for up to 6 months.

Soft cheeses like mozzarella, feta, and ricotta have a shorter shelf life

Soft cheeses, such as mozzarella, feta, and ricotta, have a shorter shelf life than harder cheeses. This is because they have a higher moisture content, which makes them more prone to spoilage from bacteria. Therefore, it is important to store them properly to extend their shelf life.

When unopened, soft cheeses typically last for a few weeks to a couple of months past their 'best by' date when refrigerated. Once opened, soft cheeses should be consumed within one to two weeks. It is important to note that the shelf life of soft cheese is influenced by factors such as the processing method, packaging date, exposure to heat, and storage conditions. To extend the shelf life of soft cheeses, they should be stored in a refrigerator at 40°F or lower immediately after each use. They should also be stored in a tightly closed container or wrapped in plastic to keep out moisture and other contaminants.

Some signs that soft cheese has gone bad include the growth of blue or green mold, darkening or hardening around the edges, and changes in texture, such as becoming overly dry, crumbly, or slimy. If you notice any of these signs, it is best to discard the entire cheese product.

Additionally, it is important to note that freezing soft cheeses is not recommended as it can alter their texture and consistency. However, if you choose to freeze soft cheeses, use a freezer-safe container, and they can be stored for up to six months.

Freezing sealed cheese can extend its shelf life, but may affect its texture

Freezing sealed cheese is a great way to extend its shelf life, but it's important to note that this method can affect the texture of the cheese. While freezing cheese can increase its longevity, it may also result in a drier and crumblier texture. This is because the freezing process causes small ice crystals to form inside the cheese, disrupting its internal structure. When the cheese is eventually thawed, water is released, contributing to its drier texture.

Hard and semi-hard cheeses, such as cheddar, Swiss, and blue cheese, can be frozen, but they may become crumbly and mealy, and more challenging to slice. However, they will still melt well, making them suitable for dishes like sauces, pizza, or grilled cheese sandwiches. Mozzarella and pizza cheese are also good candidates for freezing, especially when shredded, although their melting properties may be slightly impacted.

On the other hand, soft cheeses like Camembert, brie, ricotta, and cottage cheese have a higher water and fat content, which can lead to more ice crystal formation and a more noticeable change in texture upon thawing. Freezing is not recommended for these varieties if you plan to consume them as part of an appetizer spread or cheese board. Instead, it's best to buy and serve these cheeses fresh.

When freezing cheese, it's important to prepare it properly for storage. Portion the cheese into quantities that you're likely to use at one time, as cheese shouldn't be refrozen after thawing. Wrap the cheese or store it in its original packaging, then place it in an airtight container or bag to prevent dry air from causing freezer burn. Freeze the cheese as quickly as possible to prevent the formation of large ice crystals, and aim to use it within 6 to 9 months for the best quality.

In summary, freezing sealed cheese can be a useful way to extend its shelf life, but it's important to be aware of the potential impact on texture. Frozen cheese is best suited for cooked dishes where changes in texture are less noticeable, ensuring you get the most out of your cheese while maintaining its functionality and flavour.
