Cheddar cheese is a hard cheese that can be stored in the refrigerator or freezer to prolong its shelf life and prevent mold growth. When left exposed to oxygen, cheddar cheese can dry out and become susceptible to mold and spoilage within two weeks. To prevent this, it is recommended to tightly wrap the cheese in an airtight material, such as plastic wrap, and store it in the refrigerator at a temperature between 35°F and 45°F (2°C to 7°C). Freezing cheddar cheese can also be an effective way to prevent mold, but it may alter the texture and cause crumbling upon defrosting. Proper storage and handling practices, such as minimizing direct contact with the cheese, can help extend the shelf life of cheddar cheese and delay the onset of mold.

What You'll Learn
Cheddar cheese mould prevention methods
Exposure to air is one of the most significant factors in accelerating the deterioration of cheese. When cheese is exposed to oxygen, it not only begins to dry out but also becomes more susceptible to mould growth and spoilage. To prevent this, it is essential to tightly wrap the cheese in an airtight material, such as plastic wrap, to minimize its exposure to air. This is especially important for harder cheeses like cheddar, which can dry out more quickly than softer varieties.
To prevent mould, it is also crucial to avoid direct contact with cheese. This means using gloves or ensuring that the packaging creates a barrier between your hands and the cheese. Even with thorough hand washing, bacteria can still be transferred to the cheese, encouraging mould growth.
If mould is found on hard or semi-hard cheeses like cheddar, it is safe to cut off the mouldy area. Use a clean, sharp knife to cut at least a quarter of an inch around and below the mouldy spot, being careful not to let the knife touch the mould. Once the mould is removed, treat the remaining cheese as a fresh block by resealing it tightly.
For soft cheeses like cream cheese, if mould develops, it is best to discard the entire product. Soft cheeses are more susceptible to mould penetration, and it is not safe to consume them if mould is present.
Other methods to prevent mould growth on cheese include managing humidity levels, regular cleaning and sanitization of storage areas, and using modified atmosphere packaging. These methods help control undesirable mould growth while preserving the quality of the cheese.

How to safely remove mould from cheddar cheese
Mould can develop on cheddar cheese if it is not stored properly. To prevent mould from growing on your cheddar cheese, it is essential to wrap it tightly in an airtight material, such as plastic wrap, to minimise exposure to oxygen and avoid drying out the cheese. Even the most thorough hand washing can leave trace amounts of bacteria that can encourage mould growth, so it is best to avoid direct contact with the cheese by using gloves or ensuring that the packaging creates a barrier between the cheese and your hands.
If you do find mould on your cheddar cheese, it is important to know how to safely remove it. Firstly, determine the type of cheese you have. For hard or semi-hard cheeses like cheddar, it is safe to cut off the mouldy area. Use a clean, sharp knife to cut at least a quarter of an inch around and below the mouldy spot, ensuring that the knife does not touch the mould. Once the mould is removed, clean the knife and reseal the remaining cheese tightly to prevent further mould growth.
However, it is important to note that this method is not suitable for soft cheeses like cream cheese or Brie. If mould develops on soft cheeses, it is recommended to discard the cheese as mould can penetrate deeper into its structure. As an alternative to cutting off the mould, you can use white vinegar to remove it. Dampen a clean cloth with white vinegar and gently wipe away the mouldy spots on the cheese. Allow the cheese to air dry and then re-wrap it using proper storage techniques.
While most types of mould are not harmful, they can compromise the taste of the cheese. Additionally, if the cheese was stored next to meat or fish, it is best to discard it due to the possibility of cross-contamination.

How long does cheddar cheese last in the freezer?
Cheddar cheese is a hard cheese with a lower moisture content and higher salt content, which aids in its preservation. When stored in the freezer, a chunk of cheddar cheese will maintain its best quality for about six months to eight months, but it will remain safe to consume beyond that time. To freeze a chunk or block of cheddar cheese, cut the cheese into portions no larger than half a pound each, and wrap them tightly in heavy-duty aluminum foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag.
Freezing cheese can cause it to become crumbly and lose some of its flavor, so it is best suited for cooked dishes like sauces, soups, and casseroles. To defrost, keep the wrapped cheese in the refrigerator and let it thaw gradually, which can take one to two days. After defrosting, the cheese can be kept for an additional three to four days in the refrigerator.
To extend the shelf life of cheddar cheese, it is important to store it properly. Cheddar cheese should be tightly wrapped in an airtight material, such as plastic wrap, to minimize exposure to air and prevent drying out. Additionally, it should be stored on the top or middle shelf, or in a drawer, of the refrigerator, and kept above raw meats, poultry, and fish to avoid contamination.
Even with proper storage, mold can sometimes develop on cheddar cheese. If this happens, the mold can be cut off, and the rest of the cheese can be safely consumed. However, if the cheese smells off, it is best to discard it.

The best way to store cheddar cheese in the fridge
Cheddar cheese is a semi-hard cheese that can be stored in a variety of ways to extend its shelf life. While there is no single correct way to store cheese, taking proper care of it can make it last longer in the fridge.
Firstly, it is important to understand the characteristics of cheddar cheese. As a semi-hard cheese, cheddar has a higher moisture content than hard cheeses like Parmesan, but it is drier than soft cheeses like feta or Brie. This means that cheddar is more susceptible to mould growth and spoilage than hard cheeses, but it will last longer than soft cheeses.
To prevent mould growth and spoilage, cheddar cheese should be tightly wrapped in an airtight material such as plastic wrap or wax paper to minimise exposure to air. This helps to reduce the introduction of harmful bacteria and prevents the cheese from drying out. However, some sources suggest avoiding plastic wrap, as it can cause condensation and sweating, leading to oxidation and dehydration. Instead, reusable containers or specialty cheese paper that allows the cheese to breathe can be used.
It is also important to store cheddar cheese in the correct location in the fridge. While most fridges have a "cheese drawer", cheddar cheese is better kept in one of the bins usually reserved for vegetables at the bottom of the fridge, as there is more humidity, which benefits the cheese.
Additionally, it is recommended to only slice cheddar cheese as needed. Slicing increases the surface area of the cheese, exposing more of it to possible contamination, oxidation, and dehydration, which shortens its shelf life.
By following these storage tips, you can extend the shelf life of your cheddar cheese and prevent mould growth. However, if mould does appear, it can be safely removed by scraping or cutting off the affected area with a knife or cheese plane, as long as it has not been contaminated by other foods.

Why does cheddar cheese get mouldy so fast?
Cheddar cheese is a hard variety of cheese that is particularly susceptible to drying out and mould growth. While all cheese will eventually be consumed by mould, some types of cheese are more resistant than others. Soft cheeses, for example, tend to have a shorter shelf life of around 1-2 weeks, whereas hard cheeses can last several months.
Cheddar cheese is particularly prone to mould because of its lower moisture content. Hard cheeses like cheddar are more susceptible to drying out, and when exposed to oxygen, they can quickly become host to mould. This is why it is important to store cheese properly, in an airtight container, and at the correct temperature. The ideal temperature for storing most cheeses is between 35°F and 45°F (2°C to 7°C).
Another factor that contributes to mould growth is the introduction of bacteria. Even with thorough hand washing, trace amounts of bacteria can be transferred to the cheese, encouraging mould to grow. This is why it is recommended to avoid direct contact with cheese, using gloves or a barrier, like plastic wrap, between your hands and the cheese.
To prolong the life of cheddar cheese, it is important to store it properly. This includes wrapping the cheese tightly to reduce exposure to air, storing it in the refrigerator, and keeping it separate from other foods to prevent cross-contamination of flavours and mould spores. If you have a large block of cheese, consider cutting it into smaller portions and wrapping them individually. This will help reduce the surface area exposed to potential mould spores each time you use the cheese.
Additionally, freezing is an effective way to prolong the life of cheese. While freezing can alter the texture of some cheeses, it can be a good option for hard cheeses like cheddar. To freeze cheese, wrap it tightly and place it in a resealable plastic bag, removing as much air as possible. Then, thaw the cheese slowly in the refrigerator before consuming.
