Cheddar cheese is a semi-soft or semi-firm cheese with a relatively low moisture content, which means it has a longer shelf life than soft cheeses like Brie, Camembert, or cottage cheese. While cheddar cheese does have an expiry date, it can be safely consumed for up to three weeks after this date, provided it has been stored properly. To ensure the safety of consumption, it is important to inspect the cheese for any signs of spoilage, such as mould, odd odours, a slimy texture, or a sour flavour. If mould is present, it is generally safe to cut off the mouldy part and consume the rest of the cheese. However, it is important to use one's judgment and common sense when deciding whether to consume cheddar cheese past its expiry date.
| Characteristics | Values |
|---|---|

| Safe to eat if it has a sour flavour? | No, throw it out. |

Cheddar can be kept for years, but it's not advisable to do so
Cheddar is a semi-soft or semi-firm cheese with a relatively low moisture content, which means it can be stored for several months and is safe to eat for up to three weeks after the listed expiration date. However, it's not advisable to keep cheddar for years due to the potential risk of foodborne illness and the degradation of taste and texture over time.
Cheddar cheese, like all dairy products, has a finite shelf life and will eventually spoil. While the low moisture content of cheddar slows down the growth of bacteria, it doesn't prevent it entirely. Over time, even properly stored cheddar will develop an off taste or smell, indicating that it's no longer safe to consume.
Additionally, the texture of cheddar can become hard and crumbly if it's kept for too long, making it less appealing for consumption. Cheddar is best enjoyed when it has a smooth, creamy texture, which can be lost if it's stored for extended periods.
Furthermore, while it is possible to cut off mouldy portions of hard cheeses like cheddar, this may not always be effective in removing all harmful bacteria. Some types of mould can penetrate deeper into the cheese, and consuming it could lead to foodborne illness, which can cause vomiting, stomach pain, or diarrhoea.
Therefore, while cheddar can technically be kept for years, it's not recommended to do so. It's best to prioritise food safety and the enjoyment of the cheese's optimal taste and texture by consuming it within a few months of purchase or, at most, a few weeks after the listed expiration date.

Cheddar has a low moisture content, which slows the spread of bacteria
Cheddar is a hard, ripened cheese with a low moisture content. It is produced by acidifying milk and then concentrating it by forming a gel with rennet. The curds and whey are separated, and the curd is cooked to expel moisture. The cheesemaker must control the process to ensure that the desired acid development in the curd is reached at the same time as the required moisture content.
Cheddar's low moisture content is important because it slows the spread of bacteria. The maturation rate of cheese depends on the amount and type of enzyme present, as well as the composition of the product. The composition determines the environment in which enzyme and subsequent chemical activity can occur. The longer the ripening process, the less moisture the cheese retains, and the firmer and stronger-tasting the cheese will be.
Salt is added to cheddar to control the growth of microorganisms, specifically starter bacteria and undesirable species. It also slows down the development of microorganisms, improves the storage life of the cheese, and speeds up the drying process and the formation of a rind. The salt crystals dissolve as they are applied, leading to higher salt retention.
Cheddar cheese has a long shelf life due to its low moisture content and other factors such as salt content and proper storage. When stored in a refrigerator at a temperature below 40°F (4°C), cheddar cheese can last for several weeks. However, it is important to inspect the cheese for any signs of spoilage, such as mould, unpleasant odours, or changes in texture. If mould is present, it is generally safe to cut off the mouldy portion and consume the rest of the cheese.

Cheddar should be stored in porous material like wax or parchment paper
Cheddar cheese, like all other cheeses, has an expiry date. However, this date is not set in stone. Cheddar can be kept for additional years beyond its expiry date. But how do you know when cheddar cheese has gone bad?
Firstly, inspect your cheese. If you notice specks of blue, green, orange, or red mould, cut off at least 1 inch (2.5 cm) around and below those spots. If you have a healthy immune system, you will likely be fine if you accidentally eat a mouldy spot, but monitor yourself for symptoms of food poisoning like vomiting, stomach pain, or diarrhoea. White specks or crystallized patches on cheddar are normal and safe to eat. These spots are most likely not mould but calcium lactate crystals, which form when the lactic acid in cheese combines with calcium.
To prevent mould, cheddar should be stored in porous material like wax or parchment paper. Wrapping cheddar in tight, non-porous material like plastic wrap can dry it out and harden it. Wax or parchment paper allows the cheese to breathe, enabling moisture to wick off the cheese. Then, a layer of aluminium foil can be added to prevent the moisture from escaping entirely.
It is also important to store cheddar at the right temperature. A safe fridge temperature is below 40°F (4°C). Higher temperatures significantly increase the rate at which bacteria multiply, which raises the risk of spoilage.

Cheddar can be kept in the fridge for 3-4 weeks after opening
Cheddar is a semi-hard cheese with a relatively long shelf life. Once opened, it can be kept in the fridge for 3-4 weeks. This is because it has a low moisture content, which means bacteria cannot spread as quickly, so it stays fresh for longer.
However, this shelf life is not set in stone and depends on how the cheese is stored. Cheddar should be wrapped in wax, parchment, or cheese paper and kept on the top or middle shelf of the fridge, or in a drawer. It should be stored above raw meats, poultry, and fish to avoid contamination. It is also important to keep the fridge temperature below 40°F (4°C).
If stored correctly, Cheddar can even be kept for several years. However, if the cheese is not properly wrapped and stored, it can develop mold. If this happens, simply cut off the moldy part plus an extra 1/8 to 1/4 of an inch and the rest of the cheese can still be eaten.
It is important to use your common sense and instinct when deciding whether to keep or throw away cheese that has passed its expiration date. While Cheddar can be kept for 3-4 weeks in the fridge after opening, it is always a good idea to inspect the cheese to ensure it is safe to eat.

Cheddar is safe to eat after its best-before date if stored properly
Cheddar is a semi-soft or semi-firm cheese, and as such, it has a longer shelf life than soft cheeses like cottage cheese, cream cheese, ricotta, Brie, mozzarella, Neufchâtel, feta, Gorgonzola, and Camembert. These soft cheeses have a high moisture content, which means bacteria and mould can spread more easily, so they should be consumed within a week of their best-before date.
On the other hand, hard cheeses like Parmesan and Pecorino have a much lower moisture content, which slows down the growth of bacteria, keeping them fresher for longer. These can be safely consumed for up to two months after their printed expiration date, provided they are stored properly.
As a middle-ground option, semi-soft and semi-firm cheeses like cheddar, Gouda, and Swiss tend to have a shelf life of several months. They can generally be safely consumed for up to three weeks after their listed expiration date. However, this also depends on how the cheese is stored. Cheddar, when stored properly, can even be kept for additional years.
To store cheddar cheese properly, it should be wrapped in porous material like cheese or wax paper to prevent it from drying out. It should then be placed in an airtight container or a Ziploc bag to limit airflow. The fridge temperature should be maintained below 40°F (4°C). At higher temperatures, bacteria multiply more rapidly, increasing the risk of spoilage.
When consuming cheddar cheese past its best-before date, it is important to closely examine the cheese. If there is mould, cut off at least 1 inch (2.5 cm) around and below the affected areas. If the cheese smells odd or sour, it is best to discard it. Additionally, white specks or crystallized patches on cheddar are typically calcium lactate crystals, which are safe to consume.
