Cheese Expiration: How Long Does It Actually Last?

The shelf life of cheese depends on the type of cheese and how it's stored. Soft cheeses like Brie, Camembert, cream cheese, ricotta, and cottage cheese have a shorter shelf life, lasting a few weeks to a couple of months past their 'best by' date. Semi-hard cheeses like Swiss cheese, Cheddar, Gouda, and Provolone have a relatively long shelf life, lasting several months past their 'best by' date. Hard cheeses like Parmesan, Asiago, and Romano have the longest shelf life, lasting several months to a year or more. Blue cheeses like Stilton, Roquefort, and Gorgonzola can have a shelf life of several months. Proper storage is key to extending the shelf life of cheese, as cheese is highly perishable and can quickly degrade if not stored properly.

Hard cheese can last up to a year unopened in the fridge

Hard cheese, such as Cheddar, Parmesan, and Gouda, can last for several months to a year when stored unopened in the fridge. This is because hard cheeses have a lower moisture content, which inhibits bacterial growth and extends their shelf life.

The shelf life of hard cheese can be influenced by factors such as the type of cheese, processing method, packaging date, exposure to heat, and storage conditions. Proper storage is crucial to maximize the shelf life of hard cheese. It should be stored in the refrigerator at a temperature of 40°F or lower, either in its original wrapper or a tightly closed container, to prevent moisture and contaminant intrusion.

It's important to note that "best-by" or "sell-by" dates on cheese are guidelines for quality rather than safety. Hard cheese can often be safely consumed beyond these dates if stored correctly. However, it's always recommended to inspect the cheese for any signs of spoilage, such as mold, discoloration, or changes in texture and smell, before consumption.

Additionally, hard cheese can be frozen for a few months to extend its shelf life further. Freezing should be done using a freezer-safe container that is void of oxygen to preserve the taste of the cheese.

Soft cheeses like Brie and Camembert have a shorter shelf life

Soft cheeses, like Brie and Camembert, have a shorter shelf life than harder cheeses. This is because they contain more moisture, creating an environment where bacteria can thrive and cause spoilage. Soft cheeses should be consumed within one to two weeks of their printed date, or within two weeks of purchase if they are not sold with a use-by date.

To extend the shelf life of soft cheeses, they should be stored in a refrigerator at 40°F or lower immediately after each use. They should be kept in a tightly closed container or wrapped in plastic to keep out moisture and other contaminants. Soft cheeses should not be kept at room temperature for extended periods, as the temperature increase will cause the cheese to degrade quickly.

It is not recommended to freeze soft cheeses, as the texture and consistency will change. However, if you do choose to freeze them, use a freezer-safe container and be aware that the cheese will only keep for up to six months.

To determine if a soft cheese has gone bad, your senses are usually the most reliable tool. The most common trait of spoilage in soft cheese is the growth of blue or green mould. Once mould is visible, the entire product should be discarded, unlike hard cheeses where the mould can be cut off. Although some moulds on cheese are harmless, many can produce dangerous toxins. In addition to mould, some soft cheeses will darken or harden around their edges, which is another sign of spoilage.

Blue cheese can last several months unopened in the fridge

Blue cheese is a beloved variety of cheese with a pungent taste and scent. It is characterised by the presence of edible blue or green mould, which is perfectly safe to eat. However, like all cheeses, blue cheese can spoil and knowing how to spot this is essential for food safety.

Blue cheese, when unopened, can last for several months in the fridge. This is because blue cheese has a lower moisture content, which helps extend its shelf life. Proper storage is crucial to maximise the shelf life of blue cheese. It should always be kept in the refrigerator and wrapped tightly in plastic wrap or aluminium foil. For optimal results, wrap the cheese first in wax or parchment paper before covering it with plastic wrap.

Even after the "sell-by" or "best-by" date on the package, blue cheese will typically remain safe to consume for 1 to 2 months if stored properly. It is important to note that these dates are guidelines for quality rather than safety. Cheese often remains safe to eat beyond these dates if stored correctly.

To further extend the shelf life of blue cheese, it can be frozen. Cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. Frozen blue cheese will maintain its best quality for about 6 months but will remain safe to consume beyond this period.

It is important to be vigilant for signs of spoilage in blue cheese. The cheese will typically develop a very hard texture, darken in colour, and emit a strong smell when it is going bad. Additionally, mould may appear, indicating that it is time to discard the cheese.

Fresh cheese is highly perishable and usually lasts a few weeks past its 'best by' date

Fresh cheese is highly perishable and usually lasts a few weeks past its best-by date. Soft cheeses like Brie, Camembert, feta, and mozzarella have higher moisture levels, making them more susceptible to bacterial growth at room temperature. This means they can spoil more quickly than hard cheeses like Cheddar or Parmesan. Soft cheeses will last for a week or two, maybe even three if stored correctly.

To extend the shelf life of soft cheeses, it is recommended to store them in their original packaging in the refrigerator. If the original packaging is not suitable, wrap the cheese in wax paper or parchment paper to allow it to breathe while still protecting it from moisture loss. Proper storage can help maintain the quality and safety of the cheese when it is not kept refrigerated.

Hard cheeses, on the other hand, have lower moisture levels, which inhibits bacterial growth and allows them to last longer unrefrigerated. They can be stored in the refrigerator in a resealable plastic bag or airtight container to protect against moisture and exposure to other odors. Hard cheeses will last much longer than soft cheeses, from a few months to basically forever.

It is important to note that the shelf life of cheese can vary depending on factors such as the type of cheese, moisture content, processing method, packaging date, exposure to heat, and storage conditions. Additionally, consuming unrefrigerated cheese comes with potential health risks due to the growth of harmful bacteria such as listeria, salmonella, and E. coli. Therefore, it is recommended to refrigerate cheese if it is not going to be consumed within a few hours to prevent spoilage and foodborne illness.

Cheddar cheese can last a year or more past its 'best by' date when stored in the fridge

Cheddar cheese is a semi-hard cheese with a relatively long shelf life. When unopened, it can last for several months and even up to a year or more when stored in the fridge. This is because Cheddar has a lower moisture content, which helps extend its shelf life.

Once opened, the shelf life of Cheddar cheese declines considerably due to exposure to air and potential bacterial contamination. However, when stored in the refrigerator in a wrapper or airtight container, opened Cheddar cheese can still last for a few weeks to a couple of months.

To ensure the cheese lasts as long as possible, it is important to store it properly. Cheddar cheese should be removed from its plastic packaging and wrapped loosely in a pliable yet breathable material, such as wax paper or cheese paper, before being placed in an airtight container.

It is worth noting that the "best by" or "sell by" dates on cheese are guidelines for quality rather than safety. Cheese often remains safe to eat beyond these dates if stored correctly. However, it is always advisable to inspect the cheese for any signs of spoilage, such as mould, discolouration, or a change in texture or taste, before consuming.
