What You'll Learn
Cheddar is a semi-hard cheese
Cheddar cheese is a semi-hard cheese, which means it has a slightly softer texture than hard cheeses like Parmesan and Gruyere but is still firm enough to be sliced, grated, or cubed. Semi-hard cheeses are aged similarly to hard cheeses, but for a shorter period of time, typically anywhere from one to six months. This gives them a milder taste than hard cheeses while maintaining their versatility.
The aging process of semi-hard cheeses like cheddar involves pressing the curds to remove most of the whey, resulting in a dense and consistent texture. They are then aged, developing a firm but slightly springy texture. This aging process removes moisture, making cheddar and other semi-hard cheeses less susceptible to bacterial growth and spoilage. As a result, they can be left out at room temperature for longer periods than soft cheeses without spoiling.
When it comes to storing cheddar cheese, it is important to wrap it properly to maintain its freshness. Avoid using plastic wrap, as it traps moisture and can encourage mold. Instead, opt for cheese paper, wax paper, or parchment paper, and then loosely wrap it in foil. Proper storage can extend the shelf life of cheddar cheese, allowing it to stay good for 3 to 4 weeks in the refrigerator after opening.
To maximize the shelf life of a block of Wisconsin cheddar cheese, it is recommended to store it in the refrigerator, properly wrapped in the appropriate materials. With proper storage, a block of Wisconsin cheddar cheese can last for several weeks to months. Additionally, when storing cheese, it is crucial to maintain a safe refrigerator temperature of below 40°F (4°C).
It is worth noting that while cheddar is considered a semi-hard cheese, the aging process can vary, resulting in different textures. Some cheddars, like premium specialty cheddars, are aged for longer periods, resulting in a harder texture that can be aged for up to two or more years. Therefore, the storage time may vary depending on the specific type of cheddar cheese.

How to store cheddar
Cheddar is a hard, low-moisture cheese that can last for months when stored correctly. Here are some tips on how to store cheddar cheese to maintain its freshness and quality:
Choose the Right Storage Materials
Avoid storing cheddar in plastic wrap or containers as they can trap moisture and encourage mould growth. Instead, opt for breathable materials like wax paper, cheese paper, or cheesecloth. These materials allow the cheese to breathe while also protecting it from excessive drying or mould.
Store in an Airtight Container
After wrapping the cheddar in wax or cheese paper, place it in an airtight container or a resealable plastic bag. Squeeze out as much air as possible from the bag before sealing it. This helps to maintain humidity and prevent the cheese from drying out.
Keep it in the Fridge
Store the wrapped cheddar in the refrigerator to prolong its freshness. The ideal temperature for storing cheese is between 50-60°F (10-16°C). Place it in a dedicated cheese drawer, if available, or on a shelf away from direct airflow to prevent drying.
Handle with Clean Utensils
Always use clean utensils when handling cheddar cheese. Bacteria from knives or other tools can transfer to the cheese, reducing its shelf life. Additionally, avoid pre-grating the cheese, as grated cheese has a shorter shelf life. Instead, grate only the amount you need for each use.
Regularly Check for Mould
Inspect the cheddar cheese regularly for any signs of mould. If you spot a small mould spot, trim off the affected area, ensuring to cut at least 1 inch (2.5 cm) around and below the mould. The remaining cheese is generally safe to consume. However, if the mould is pervasive, discard the entire block.
By following these storage guidelines, you can extend the freshness of your cheddar cheese and enjoy its flavour and quality for a longer period.

How long does unopened cheddar last?
Cheddar cheese is a hard cheese with a low moisture content, which helps extend its shelf life. Unopened cheddar cheese can last for several months to even a year or more past its 'best by' date when stored properly in the fridge. The USDA states that unopened hard cheeses like cheddar will last for six months in the fridge.
When stored in the refrigerator in a wrapper or airtight container, opened cheddar cheese can last for a few weeks to a couple of months. Once opened, exposure to air and potential bacterial contamination causes the shelf life to decline considerably. Opened hard cheeses like cheddar can last for three to four weeks in the refrigerator, provided proper storage techniques are followed.
Proper storage techniques for opened cheddar cheese include wrapping it in cheese paper or wax paper and then loosely in foil. Avoid plastic wrap, which traps moisture and can encourage mould. If mould appears on the surface of hard cheese, the FDA says it is generally safe to cut away the mould (at least 1 inch around and below) and continue enjoying the rest.
Taste is also indicative of spoilage. If a cheese has undergone a significant change in flavour (for example, from mild to sharp, or nutty to sour), it has likely gone bad.

How long does opened cheddar last?
Cheddar is a hard cheese with a lower moisture content and higher salt content than soft cheese. This, combined with an intense aging period, aids in its overall preservation and gives it a longer shelf life in the fridge. Once opened, a block of cheddar cheese will typically stay good for 3 to 4 weeks if stored properly.
To extend the shelf life of opened cheddar cheese, it is important to follow proper storage techniques. Cheddar cheese should be wrapped in wax paper, parchment paper, or cheese paper, then stored in an airtight container like a Tupperware or Ziploc bag. Avoid using plastic wrap, as it traps moisture and can encourage mold growth. If mold appears on the surface of hard cheese, it is generally safe to cut away the affected area (at least 1 inch or 2.5 cm around and below) and continue enjoying the rest of the cheese.
It is important to note that the shelf life of opened cheddar cheese may vary depending on factors such as the quality of the cheese, storage conditions, and the presence of bacteria. Therefore, it is always a good idea to inspect the cheese for any signs of spoilage, such as mold, strange odours, or changes in texture, before consuming it.
Additionally, proper handling of the cheese is crucial to prevent the introduction of bacteria that can shorten its shelf life. Use clean utensils when handling the cheese, and if grating, grate only the amount of cheese needed and store the rest of the block separately to maintain freshness.
By following these storage and handling tips, you can maximize the shelf life of opened cheddar cheese and enjoy it for a longer period of time.

How to spot signs of spoilage
Cheddar is a hard cheese, and as such, it has a longer fridge life than soft cheeses. This is due to its lower moisture content, which makes it less prone to spoilage from bacteria. However, hard cheeses can still go bad, so it's important to know how to spot the signs of spoilage.
One of the most obvious signs of spoilage in hard cheeses like cheddar is the presence of mould. While some moulds on cheese are harmless or even desirable, such as those found in blue cheese, uncontrolled mould growth may produce toxins that can make the cheese unsafe to eat. If you see any blue, black, grey, pink, or fuzzy mould, the cheese should be discarded. If you notice white specks or crystallized patches, these are usually safe to consume and are caused by the formation of calcium lactate crystals.
In addition to mould, spoilage in cheddar cheese can also be identified by changes in colour, texture, or smell. A significant change in colour, such as browning or yellowing, can indicate that the cheese has spoiled. Hard cheeses may also become dry, crusty, crumbly, or brittle due to moisture loss, and can develop cracks. An unpleasant, rancid, or ammonia-like odour can also be a sign of spoilage, as can a slimy or greasy texture.
To prevent spoilage, cheddar cheese should be stored properly, consumed within a reasonable amount of time, and handled with clean utensils. It is recommended to store hard cheeses in a sealed container or wrapped in wax or cheese paper, and to maintain a cool temperature with good air circulation to prevent cracking.
By being aware of the signs of spoilage and applying proper storage practices, you can help ensure that your cheddar cheese remains safe and delicious to eat.
