Hard cheeses are low in moisture, making it difficult for bacteria to flourish. This means that once opened, a package of hard cheese can last a long time—sources suggest anywhere from three to eight weeks in the refrigerator. Unopened packages of hard cheese can last about six months in the fridge, according to experts at the USDA.

What You'll Learn
Hard cheese can be stored in the fridge for up to four months unopened
Hard cheeses, such as Cheddar, Parmesan, and Gouda, are low-moisture foods, which means bacteria find it difficult to flourish on them. This gives hard cheeses a longer shelf life than soft cheeses.
Once opened, hard cheese can last for up to four weeks in the refrigerator. To prolong its life, follow the same storage steps as for unopened hard cheese. If you notice mould on your hard cheese, simply cut off at least 1 inch (2.5 cm) around and below the mouldy area. White specks or crystallized patches on certain aged hard cheeses, such as cheddar, parmesan, and gouda, are normal and safe to eat. These spots are most likely not mould but calcium lactate crystals.

It can last up to six months in the freezer
Hard cheeses, such as cheddar, parmesan, and gouda, are low in moisture, which makes it difficult for bacteria to flourish. This means that hard cheeses can last a long time in the fridge. According to experts, unopened hard cheeses can last for several months and even up to a year when stored in the fridge.
Once opened, a package of hard cheese can last for about four weeks in the refrigerator. However, if you want to extend the shelf life of your hard cheese, freezing is a great option. Hard cheeses can last up to six months in the freezer, providing a convenient way to preserve your favourite cheese for a more extended period.
Freezing hard cheese is a simple and effective method to ensure its longevity. When frozen, hard cheese can be safely stored for up to half a year. This process involves removing the cheese from its original packaging and placing it in an airtight container or freezer bag. It is also essential to wrap the cheese loosely in a breathable material, such as wax paper or cheese paper, to allow it to breathe and release moisture.
While freezing hard cheese can alter its texture, making it crumblier, it is still perfectly safe to consume. Freezing is an excellent option for those who want to stock up on their favourite hard cheeses or need to prolong their cheese's life.
In summary, hard cheese can be safely stored in the freezer for up to six months. This extended shelf life is a result of the low moisture content in hard cheeses, which inhibits bacterial growth. By following the proper storage methods, you can enjoy your favourite hard cheeses for a more extended period without worrying about spoilage.

Once opened, hard cheese can be stored in the fridge for six weeks
Hard cheese is a treat for the taste buds, and it's always handy to have some in the fridge. But how long does hard cheese last once opened? Well, the good news is that it can be stored in the fridge for up to six weeks. That means you can enjoy your favourite hard cheese for almost two months after opening!
Hard cheeses, such as Cheddar, Parmesan and Gouda, are known for their long shelf life. This is because they have a lower moisture content, which creates an environment less conducive to bacterial growth. As a result, hard cheeses can be stored for much longer than their softer counterparts, which tend to spoil more quickly.
To ensure your hard cheese lasts for up to six weeks in the fridge, there are a few storage best practices to follow. Firstly, remove the cheese from its original plastic packaging, as this can affect its quality and taste over time. Instead, wrap the cheese loosely in a breathable material, such as wax paper or cheese paper. This allows the cheese to breathe and release moisture while protecting it from the low humidity of the fridge. Then, place the wrapped cheese in an airtight container and store it in the refrigerator.
It's worth noting that while hard cheese can be stored in the fridge for six weeks, its quality and taste may start to decline after a few weeks. So, if you're a cheese connoisseur, you might want to finish it within a few weeks to ensure the best flavour and texture. Additionally, always inspect hard cheeses for mould before consuming, and cut off any spots that may have developed.
By following these simple storage tips, you can maximise the shelf life of your hard cheese and enjoy it for almost two months after opening!

Hard cheese can be frozen to prolong its life
Hard cheeses like cheddar, parmesan, and gouda can be kept unopened in the fridge for up to six months. Once opened, hard cheese is generally safe to eat for about four weeks. However, freezing hard cheese can extend its shelf life by several months.
When freezing hard cheese, it is important to prepare it properly for storage. First, portion the cheese into quantities that you are likely to use at one time. For large blocks of cheese, it is recommended to freeze no more than one pound (500 grams) per portion. You can also grate or slice the cheese before freezing.
Next, wrap the cheese in its original packaging or use foil or cheese paper. If using sliced cheese, separate the slices with parchment paper. Then, place the wrapped cheese in an airtight container or bag to prevent dry air from getting into the cheese and causing freezer burn.
It is best to freeze the cheese as quickly as possible to prevent the formation of large ice crystals, which can affect the texture and quality of the cheese. Frozen cheese should be stored at a temperature of 0°F (-18°C) or below and can be kept indefinitely. However, for the best quality, it is recommended to use the cheese within six to nine months.
When you are ready to use the frozen hard cheese, thaw it in the refrigerator for seven to eight hours per pound. It is important to note that previously frozen and thawed cheese should not be frozen again. Frozen cheese is best suited for cooked dishes where changes in texture are less noticeable, such as sauces, pizzas, or grilled cheese sandwiches.

Hard cheese can be inspected for mould and the affected areas cut off
When inspecting hard cheese for mould, it is recommended to cut off at least 1 inch (2.5 cm) around and below the affected areas. This will ensure that all the mould is removed and the cheese is safe to eat. It is also important to store hard cheese properly to prevent mould from forming. Hard cheese should be removed from its plastic packaging and wrapped loosely in breathable material, such as wax paper or cheese paper, before being placed in an airtight container in the refrigerator.
Additionally, hard cheese can last for a long time in the refrigerator, making it a great option for those who like to always have cheese on hand. Unopened hard cheese can last for several months to even a year when stored in the fridge, while opened hard cheese can last for a few weeks to a couple of months. However, it is important to note that the larger the chunk of hard cheese, the longer it will last.
In summary, hard cheese is a versatile and long-lasting option for cheese lovers. With proper storage and inspection, hard cheese can be enjoyed for many months, and any mould that forms can simply be cut off and the cheese safely enjoyed.
