Hard Cheese: Unopened, How Long Does It Last?

Hard cheese is a kitchen staple and a favourite for many, but how long does unopened hard cheese last? The shelf life of hard cheese depends on a few factors, such as the type of cheese, the moisture content, and the storage method. Generally, hard cheeses have a longer shelf life than soft cheeses because they contain less moisture, creating an environment that is not conducive to bacterial growth and, therefore, spoilage.

Hard cheese can last up to a year in the fridge

The length of time that hard cheese lasts in the fridge will depend on whether it is opened or unopened. Unopened hard cheese can last for several months to a year when stored in the fridge. Once opened, a package of hard cheese will typically last about four weeks in the refrigerator.

To make hard cheese last as long as possible, it should be stored correctly. This means removing the cheese from its plastic packaging and wrapping it loosely in cheese paper or wax paper. It should then be put in a container with an airtight lid and stored in the coldest part of the fridge.

It is also important to inspect hard cheeses for mould before eating them. If there is mould on the cheese, simply cut off at least one inch around and below the mouldy area and discard it. The rest of the cheese should be safe to eat.

In addition to the storage method, the shelf life of hard cheese will also depend on the quality of the cheese and the temperature of the fridge. A safe fridge temperature is below 40°F (4°C). At higher temperatures, bacteria can multiply more quickly, increasing the risk of food spoilage.

Unopened hard cheese should be refrigerated

When it comes to storing cheese, moisture content plays a crucial role in determining shelf life. Soft cheeses, such as ricotta, feta, mozzarella, and Brie, have a higher moisture content, making them more perishable than harder cheeses. They should be consumed within one to two weeks of being stored in the fridge. On the other hand, hard cheeses have a lower moisture content, which creates a less favourable environment for bacteria to thrive, resulting in a longer shelf life.

By refrigerating unopened hard cheese, you can significantly prolong its freshness and quality. Unopened blocks of hard cheese can last for about 6 months in the fridge. This duration may vary slightly depending on the specific type of cheese and the storage conditions. For example, an unopened chunk of cheddar cheese can be safely refrigerated for about 6 months, while other hard cheeses like Parmesan and Gouda can last for several months to even a year or more when stored in the fridge.

To maximize the shelf life of unopened hard cheese, it is recommended to keep it in its original packaging when refrigerating. This helps maintain the optimal storage conditions and delays the exposure of the cheese to air and potential bacterial contamination. Additionally, ensure that your refrigerator temperature is maintained below 40°F (4°C) to prevent bacterial growth and spoilage.

Hard cheese can be frozen for up to eight months

To freeze hard cheese, it's recommended to cut the cheese into portions no larger than half a pound each. Wrap the portions tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. Make sure to remove as much air as possible if using a freezer bag.

When it comes to thawing frozen hard cheese, it's best to give it time to breathe. Place the cheese in the refrigerator on a flat plate or surface, ideally wrapped or in an airtight container, and allow it to thaw for about 12 hours. It's important to note that cheese that has been frozen and thawed should not be frozen again.

While freezing can extend the shelf life of hard cheese, it's worth mentioning that unopened hard cheese can also be stored in the refrigerator for up to six months. This option may be preferable if you plan to consume the cheese within a shorter time frame, as freezing can affect the texture and quality.

In summary, hard cheese can be frozen for up to eight months, but freezing will impact the texture and quality. To freeze hard cheese, cut it into portions and wrap them tightly or place them in freezer bags. When thawing, allow the cheese to breathe in the refrigerator for about 12 hours. Alternatively, unopened hard cheese can be stored in the refrigerator for up to six months without freezing.

Hard cheese has a lower moisture content

The length of time that hard cheese lasts in the fridge also depends on the storage method. Proper storage allows the cheese to "breathe" and release moisture while protecting it from low humidity in the fridge. For example, hard cheeses should be removed from their plastic packaging and wrapped loosely in cheese paper or wax paper before being placed in an airtight container.

Unopened hard cheeses can also be stored without refrigeration, although they will last much longer if they are refrigerated. If stored at room temperature, hard cheeses should be kept in a cool, dry place, such as a pantry or cellar, and consumed within a few months.

Additionally, the quality of the cheese will determine how long it lasts. Unopened hard cheeses will typically remain safe to use for about 6 months, even if the "sell-by" or "best-by" date on the package expires. However, the cheese may start to lose its optimal flavor and texture after this date.

To further extend the shelf life of hard cheese, it can be frozen. When freezing hard cheese, cut the cheese into portions no larger than 1/2 pound each, and wrap them tightly in heavy-duty aluminum foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. Properly stored, frozen hard cheese will maintain its best quality for about 6 to 8 months but will remain safe to eat beyond that time.

Hard cheese should be wrapped in wax, parchment, or cheese paper

Wax paper, for example, is coated with wax and polyethylene, which creates a barrier that wicks away excess moisture while allowing the cheese to breathe. This prevents the cheese from drying out or becoming soggy and inhibits the growth of mould. Parchment paper can also be used to wrap hard cheese, providing a breathable layer that helps regulate moisture.

Cheese paper, specifically designed for cheese storage, is another effective option. It is coated with wax and polyethylene, which allows the cheese to breathe and prevents it from drying out or tasting like plastic. While cheese paper can be more expensive, it is a good investment for those who regularly consume large quantities of cheese.

When wrapping hard cheese, it is important to avoid using tight, non-porous materials such as plastic wrap. Plastic wrap can smother the cheese, leading to premature spoilage and the development of mould. It can also cause the cheese to take on a plastic-like taste. Instead, opting for porous materials like wax, parchment, or cheese paper helps to maintain the quality and freshness of the cheese.

By following these wrapping and storage guidelines, you can maximise the shelf life of hard cheese, ensuring that it remains edible and flavourful for a longer period of time.
