Cheese Lifespan: How Long Does It Last In The Fridge?

Cheese is a delicious and versatile food, but it's important to know how long it lasts in the refrigerator to avoid food poisoning. The shelf life of cheese depends on its moisture content, storage practices, and preservatives. Soft cheeses like ricotta, feta, and mozzarella have a high moisture content, making them more perishable, with a fridge life of about one week. In contrast, hard cheeses like aged cheddar, aged gouda, and parmesan have low moisture content, making it difficult for bacteria to flourish, and can last up to four weeks in the refrigerator. Proper storage methods, such as using breathable materials and airtight containers, can also extend the shelf life of cheese. Additionally, factors like temperature, sanitation practices, and the presence of preservatives like salt or natamycin influence how long cheese remains edible.

Soft cheeses like ricotta, feta, and mozzarella last one week in the fridge

Soft cheeses, such as ricotta, feta, and mozzarella, are more perishable than hard cheeses because they have a higher moisture content. This moisture is necessary for bacterial growth, so these cheeses are more susceptible to spoilage. For this reason, soft cheeses will only last around one week in the fridge, even if they have been opened and stored properly.

Proper storage is key to getting the most out of soft cheeses. For cheese sold in brine, like feta or fresh mozzarella, keep it in the liquid and make sure the container's lid is secure. For blue cheese, you can wrap it in foil. Soft-ripened or semi-soft cheeses like Brie have a delicate rind, so they need more care than other soft cheeses. It is best to wrap them in cheese paper or parchment paper and keep them in an airtight container.

It is important to note that soft cheeses should not be kept at room temperature for extended periods of time, as they will quickly degrade as their temperature increases. They should be stored in the refrigerator at 40°F or lower immediately after each use. Additionally, soft cheeses should be stored in a tightly closed container or wrapped in plastic wrap to keep out moisture and other contaminants.

While soft cheeses will only last about a week in the fridge, hard cheeses can last much longer. Unopened blocks of hard cheese can last up to 6 months in the fridge, while opened packages will last about 4 weeks.

Semi-soft cheeses like Brie should be wrapped in cheese or parchment paper and kept in an airtight container

Soft cheeses like ricotta, feta, and mozzarella have a high moisture content, making them more perishable than harder cheeses. In general, soft cheeses will last for about a week in the fridge. However, soft cheeses sold in brine, like feta or fresh mozzarella, can be kept in the refrigerator for up to two weeks if stored properly.

Semi-soft cheeses like Brie have a delicate rind, so they require more careful storage than other soft cheeses. When storing semi-soft cheeses, it is recommended to wrap them in cheese paper, parchment paper, or wax paper, and then place them in an airtight container. This storage method helps regulate moisture and protects the cheese from the low humidity of the fridge.

One source recommends using specialty cheese paper, such as Formaticum, for optimal airflow and humidity. If specialty cheese paper is not available, parchment paper or wax paper can be used instead. After wrapping the cheese, place it in an airtight container, ensuring no parts are left exposed to prevent drying.

Additionally, it is important to note that cheese is a living, breathing product that requires oxygen and humidity to stay fresh. Therefore, it is best to avoid storing cheese in plastic wrap, as it can trap moisture, block oxygen, and impart an unpleasant plastic-like flavour.

Semi-hard cheeses like cheddar, Gruyère, and Monterey Jack last two to three weeks in the fridge

Semi-hard cheeses, such as cheddar, Gruyère, and Monterey Jack, are beloved varieties that can be found in many refrigerators. These semi-hard cheeses contain less moisture than soft cheeses, which means they have a longer shelf life.

In general, semi-hard cheeses will last two to three weeks in the fridge. To ensure your cheese lasts the full two to three weeks, follow these steps for proper storage:

• Remove the cheese from its plastic packaging.
• Wrap it loosely in a pliable yet breathable material, such as wax paper or cheese paper.
• Put the cheese in a container with an airtight lid.

It is important to note that the shelf life of cheese can vary depending on factors such as storage practices, moisture content, and preservatives. Additionally, cheese that is not stored properly may develop signs of spoilage, such as mould, an off-smell, or a bitter taste. Therefore, it is always a good idea to inspect your cheese before consuming it, even if it is within the expected shelf life.

To further extend the shelf life of semi-hard cheeses, they can be frozen. Freezing cheese will not make it unsafe from a food safety standpoint. However, it can alter the texture of the cheese, so it is generally recommended to consume the cheese as it is.

Hard cheeses like aged cheddar, aged Gouda, and Parmigiano Reggiano last about four weeks in the fridge

Hard cheeses, such as aged cheddar, aged Gouda, and Parmigiano Reggiano, are low in moisture, making it difficult for bacteria to flourish. This gives them a longer shelf life than soft cheeses. Once opened, hard cheeses can last about four weeks in the refrigerator, according to experts like Gordon Edgar, cheesemonger at Rainbow Grocery Cooperative in San Francisco.

To maximise the shelf life of hard cheeses, proper storage is key. Firstly, remove the cheese from its original plastic packaging. Then, wrap it loosely in a pliable yet breathable material, such as wax paper or cheese paper. Finally, place the wrapped cheese in a container with an airtight lid and store it in the refrigerator.

It's also important to note that hard cheeses can be stored at room temperature, but they will last much longer if kept in the fridge. Unopened packages of hard cheese can last about six months in the refrigerator, according to the USDA.

When it comes to determining if your hard cheese has gone bad, there are a few signs to look out for. The most obvious sign of spoilage is visible, unintentional mould. However, for hard cheeses, you can simply cut off the mouldy part and the rest of the cheese should still be safe to consume. Other signs that indicate your hard cheese has gone bad include an unintentional bitter flavour, a fermented fruit taste, and a fizzy sensation on the tongue.

Freezing cheese: processed cheese slices and soft cheeses don't freeze well, but other types can be frozen for up to six months

Freezing is a great way to extend the shelf life of cheese. However, not all cheeses freeze well. Harder cheeses tend to freeze better than soft cheeses due to their lower moisture content. When cheese is frozen, its water and fat content form ice crystals that can damage the protein structure, leading to a crumbly or grainy texture after thawing.

Processed cheese slices and soft cheeses with high moisture content, such as mozzarella, ricotta, feta, and young cheddar, do not freeze well. The freezing process can cause significant changes in their structure, texture, and flavour. These types of cheese are best eaten fresh and will last for about a week in the refrigerator.

On the other hand, harder cheeses with lower moisture content, such as aged cheddar, Swiss cheese, and blue cheese, can be frozen for up to six months. While freezing may affect their texture, making them more crumbly and mealy, their flavour will remain intact.

To freeze hard and semi-hard cheeses, cut the cheese into chunks, wrap them tightly in parchment paper and foil, and place them in a resealable plastic bag. Remove as much air as possible, seal the bag, and label it with the date. Frozen cheese should be consumed within one to two months for the best quality.

When thawing frozen cheese, it is best to transfer it to the refrigerator and allow it to thaw slowly. This helps the cheese to reabsorb moisture and retain its texture. It is also recommended to use frozen cheese in cooked dishes rather than eating it raw.
