Cheddar Cheese Block: How Long Does It Last?

How long does a block of cheddar cheese last once opened? The answer depends on storage conditions and the type of wrapping used. To maximise the shelf life of a block of cheddar cheese, it should be wrapped tightly in plastic wrap, aluminium foil, or wax or parchment paper, and then covered with plastic wrap and stored in the refrigerator. When stored properly, an opened block of cheddar cheese will last for about three to four weeks in the refrigerator.

Cheddar cheese blocks can be kept for 3-4 weeks in the refrigerator

Cheddar cheese is a semi-hard cheese with a long shelf life. Once opened, a block of cheddar cheese can be kept for 3-4 weeks in the refrigerator. However, this duration can be extended by using proper storage methods.

Firstly, it is important to note that cheddar cheese should be stored in the refrigerator at all times. When storing cheddar cheese, it is recommended to remove it from its original plastic packaging. Instead, wrap the cheese in a breathable material such as wax paper, parchment paper, or cheese paper. This allows the cheese to breathe and release moisture while protecting it from low humidity in the fridge. Then, place the wrapped cheese in an airtight container and store it in the refrigerator.

Additionally, it is important to avoid touching cheddar cheese with bare hands, as bacteria from the hands can promote mould growth. When cutting the cheese, use a clean knife and work surface to avoid contamination. If mould does develop on the cheese, cut off at least 1 inch (2.5 cm) around and below the mouldy area. The rest of the cheese should still be safe to consume.

To further extend the shelf life of cheddar cheese, it can be frozen. Cut the cheese into portions no larger than 1/2 pound each and wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them in a heavy-duty freezer bag. Frozen cheddar cheese will maintain its best quality for about 8 months but will remain safe beyond that period.

By following these storage guidelines, you can maximise the shelf life of your cheddar cheese blocks and enjoy them for 3-4 weeks or even longer in the refrigerator.

Wrap the cheese in wax or parchment paper and then plastic wrap

Wrapping a block of cheddar cheese in wax or parchment paper and then plastic wrap is an effective way to store the cheese and maintain its freshness. This method helps to regulate airflow and humidity, preventing the cheese from drying out or becoming soggy.

Firstly, cut the cheese into portions that you will typically consume in a week. Wash your hands and use a clean knife and work surface to avoid contamination. Wrap each piece tightly in wax or parchment paper. Then, wrap the cheese again, this time in plastic wrap. Ensure that the plastic wrap is loose rather than tight, as tight wrapping can promote the growth of bacteria and prevent the dissipation of natural odours.

After wrapping the cheese, place it in a storage bag. Do not seal the bag completely; instead, roll the top of the bag closed to allow for some airflow. Store the wrapped cheese in the refrigerator, preferably in the crisper drawer, which maintains a cold, stable temperature.

By following these steps, you can maximise the shelf life of your cheddar cheese block and enjoy it for several weeks.

Store in an airtight container or zip lock bag

Cheddar cheese is a semi-hard cheese with a relatively long shelf life. To maximise its shelf life, it is important to store it correctly.

Storing cheddar cheese in an airtight container or zip lock bag is a good option. Firstly, remove the cheese from its original plastic packaging. Then, wrap the cheese in a breathable material such as wax paper, parchment paper, or cheese paper. Make sure the paper covers the cheese completely. Next, place the wrapped cheese inside an airtight container or zip lock bag. Ensure that you squeeze out as much air as possible before sealing the bag. Finally, store the container or bag in the refrigerator.

By following these steps, you can expect your cheddar cheese to last for about 3 to 4 weeks in the refrigerator. However, it is important to regularly inspect the cheese for any signs of spoilage, such as mold, dryness, or changes in smell. If you notice any mold, simply cut off at least 1 inch (2.5 cm) around and below the affected area.

It is worth noting that cheddar cheese can also be frozen to further extend its shelf life. To do this, 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. Frozen cheddar cheese will maintain its best quality for about 8 months but will remain safe to consume beyond that period.

Freeze cheddar cheese blocks for longer

Cheddar cheese is a hard cheese with a low moisture content, which means it is suitable for freezing. Freezing is a great way to extend the shelf life of cheddar cheese blocks and prevent waste.

How to Freeze Cheddar Cheese Blocks

Firstly, cut the cheese into portions no larger than 1/2 pound (around 500 grams) each. Then, wrap the cheese tightly in heavy-duty plastic freezer wrap or aluminium foil, or place it inside a heavy-duty freezer bag. Alternatively, you can use cheese paper, which allows the right amount of moisture to escape while holding optimal humidity.

Cheddar cheese can be kept frozen indefinitely, but it is recommended that you use the cheese within 6-9 months for the best quality.

How to Defrost Frozen Cheddar Cheese Blocks

To defrost frozen cheddar cheese, simply place it in the refrigerator and allow a couple of hours for the cheese to thaw. You can also use the cheese frozen, for example, by grating it straight into a dish.

What to Do with Thawed Cheddar Cheese Blocks

It is important to note that the texture of cheddar cheese may change after freezing, becoming drier, crumbly, and less meltable. Therefore, it is best to use thawed cheddar cheese in cooked dishes where changes to the texture are less noticeable, such as in sauces, soups, casseroles, or on pizza.

Signs of spoilage include a hard texture, dark colour, strong smell and mould

When it comes to food safety, it's always better to be cautious. If you're unsure whether your cheddar cheese block is spoiled, look out for the following signs:

Hard Texture

Hard cheeses like Cheddar can start to harden or crack when they spoil due to changes in their moisture content and the growth of unwanted bacteria. As hard cheeses age, they tend to lose moisture, which can cause them to become brittle and more prone to cracking. To prevent this, store your cheese in a cool place with good air circulation and maintain the right humidity conditions.

Dark Colour

Any significant colour change in cheese can indicate spoilage, although it may still be safe to eat. The colour change could be due to oxidation, which occurs when beta-carotene, a compound present in cow's milk, breaks down. This results in the cheese losing its characteristic yellow colour and appearing much whiter. Additionally, browning can be a sign of spoilage in certain cheeses like Gouda and Parmesan, resulting from a complex reaction between reducing sugars and amino acids from protein breakdown.

Strong Smell

Spoiled cheese can develop a range of unpleasant odours due to the growth of bacteria or the breakdown of proteins and fats in the cheese. Ammonia, butyric acid, and geosmin are some of the chemicals that can be present in spoiled cheese, giving off pungent, rancid, or musty odours. While some types of cheese may naturally have strong smells, a significant change from its normal odour can indicate spoilage.

Mould

Mould growth on cheese can be both desirable and undesirable. Some cheeses, like Stilton or Brie, are intentionally cultivated with moulds to achieve specific flavours or textures. However, if mould grows unintentionally or is not properly controlled, it can produce spores and toxins that make the cheese unsafe to eat. Different types of mould can cause various colours and patterns on the cheese, such as blue, red, or white spots. While some moulds are harmless, others can be toxic and dangerous if consumed in large amounts. Always check for unusual colours, textures, or odours to ensure the safety of your cheese.
