Cheese Lifespan In Fridge: How Long Does It Last?

Cheese is a delicious and versatile food, but it's important to know how long it lasts in the fridge 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 shelf life of about one week in the fridge. In contrast, hard cheeses like aged cheddar, gouda, and parmesan have low moisture levels, making it difficult for bacteria to flourish, and can last up to four weeks in the refrigerator. Proper storage methods, such as wrapping cheese in porous material and maintaining a fridge temperature below 40°F, can also extend the shelf life of cheese. Additionally, factors like temperature, humidity, and the presence of preservatives during the aging process influence how long cheese lasts without spoiling.

Soft cheese lasts 1-2 weeks in the fridge

Soft cheese typically lasts 1-2 weeks in the fridge, but the quality and taste will be at their prime before that time is up. This is because soft cheeses have a high moisture content, which makes them more perishable than harder cheeses.

Since the shelf life of soft cheese is so short, proper storage is key to getting the most out of the product. 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 cheese, like Brie, has a delicate rind, so it needs more care than other soft cheeses. It's best to wrap it in cheese paper, but you can also use parchment paper and keep it in an airtight container.

A wedge of cheese starts to decline the moment it's cut off the wheel, and no cheese will get better in the fridge. So, try to only buy cheese for the week ahead.

It's important to note that the shelf life of cheese in the fridge depends on its moisture content. Moisture is needed for bacterial growth, so cheeses with higher moisture levels have a shorter shelf life. In contrast, cheeses with lower moisture levels will last longer, as they lack the ideal environment for bacteria to thrive.

Soft cheeses like ricotta, feta, and mozzarella are highly perishable and typically last for a week to a few weeks in the refrigerator. Fresh cheeses like cream cheese, cottage cheese, and ricotta are also highly perishable and usually last only a few weeks past their 'best by' date when stored in the refrigerator.

Hard cheese lasts 3-4 weeks in the fridge

Hard cheese, such as aged cheddar, aged Gouda, and Parmigiano Reggiano, can last about 3-4 weeks in the fridge. This is because hard cheeses are low in moisture, which makes it difficult for bacteria to flourish.

The shelf life of cheese depends on its moisture content. Moisture is needed for bacterial growth, so cheeses with higher moisture levels have a shorter shelf life. In contrast, cheeses with lower moisture levels will last longer, as they lack the ideal environment for bacteria to thrive.

Hard cheeses are also long-lasting because they are aged for weeks or months during production, which helps to shield and preserve the cheese. This is typically done in some form of "cheese cave", where tools and equipment are used to keep the cave within a specific temperature and humidity range. Specific molds and cultures are used to outcompete potentially harmful molds and bacteria.

However, once the cheese is removed from this controlled environment, its potential for spoilage increases. Therefore, proper storage is important to enhance its shelf life. Hard cheeses should be removed from their plastic packaging and wrapped loosely in cheese paper or wax paper before being placed in an airtight container.

Cheese with mould can be cut and eaten

Cheese is a beloved food for many, but it can be disheartening to discover mould on your favourite cheddar or gouda. The good news is that in some cases, you can cut off the mouldy parts and safely eat the rest of the cheese. However, this depends on the type of cheese and the extent of the mould growth.

Firstly, it's important to understand the difference between good and bad mould. Good mould is an integral part of the cheesemaking process and includes the white coating on soft-rind cheeses like Brie or Camembert, and the blue veins in Gorgonzola. These types of mould are safe to consume and contribute to the unique flavour of the cheese.

On the other hand, bad mould is the unwelcome guest that appears on your cheese after purchase. It usually grows on the outside edges of the cheese and may be black, grey, white, green, or fuzzy. This type of mould can affect the flavour of your cheese and should be handled differently depending on the type of cheese it appears on.

For hard cheeses like cheddar or Parmesan, you can generally cut off the mouldy parts and safely eat the rest. It is recommended to cut off at least one inch around the mould to ensure that all the fungal growth is removed. This is because hard cheeses have a lower moisture content, making it difficult for the mould to penetrate deeply into the cheese.

However, for soft cheeses like ricotta, cottage cheese, or mozzarella, the presence of mould indicates that it has likely spread throughout the cheese, even if it is not visible. In this case, it is best to discard the entire container of cheese to avoid consuming spoiled food. Soft cheeses have a higher moisture content, providing an ideal environment for mould to thrive and spread.

Additionally, if you notice black or dark red mould on any type of cheese, it is best to discard it as these rare moulds can be toxic.

To prevent mould growth and extend the shelf life of your cheese, proper storage is crucial. Instead of plastic wrap, which can trap moisture and promote mould growth, use breathable materials like parchment paper, cheese paper, or wax paper. Store the wrapped cheese in an airtight container in the refrigerator. Hard cheeses can last up to four weeks when stored properly, while soft cheeses typically last about a week.

In summary, while it is safe to cut off mould and eat certain types of hard cheeses, always exercise caution. When in doubt, it is better to discard the cheese to avoid consuming potentially harmful substances.

Cheese should be wrapped in porous material

Cheese is a living, breathing thing, and it needs oxygen to thrive. When stored in the refrigerator, the goal is to let the cheese breathe while keeping it from drying out. To achieve this, it is recommended to wrap cheese in a finely porous material, such as cheese paper or baking paper, or breathable plastic wrap made especially for cheese. These materials are designed to control the amount of moisture around the surface of the cheese while still allowing oxygen to move in and out of the packaging. This helps to maintain humidity and release excess moisture to protect against the drying atmosphere of a refrigerator.

Cheese paper, for example, is a composite material with an outer wax-coated paper and an inner porous layer of plastic. This combination creates the ideal environment for all kinds of cheeses. The opacity of cheese paper blocks oxidizing light and is structured enough to protect cheeses without suffocating them. It also helps to maintain humidity and release excess moisture.

Regular plastic wrap, on the other hand, does not allow breathability and should not be used to wrap cheese. Without proper oxygen, cheese will suffocate. In a pinch, aluminium foil can be used, but it is not ideal for long-term storage.

For soft-ripened or "semi-soft" cheeses like Brie, it is best to wrap them in cheese paper. You can also use parchment paper and keep them in an airtight container. This type of cheese has a delicate rind, so it needs more care than other soft cheeses.

For blue cheese, you can wrap them in foil. Cheese that is already in brine, such as feta or fresh mozzarella, should be kept in the brine and not wrapped in porous material.

Freezing cheese ruins its texture

Freezing cheese is not recommended, as it negatively affects the texture and quality. When cheese is frozen, small ice crystals form inside, disrupting its internal structure. Once thawed, the cheese releases water, causing it to dry out and become crumbly, with a potentially mealy texture.

The impact of freezing varies depending on the type of cheese. Hard and semi-hard cheeses with lower moisture content, such as cheddar, Swiss, and blue cheese, can be frozen but will become crumbly and difficult to slice. Freezing mozzarella and pizza cheese is possible, but their texture and melting properties may suffer.

On the other hand, soft cheeses with high moisture content, such as cottage cheese, ricotta, and fresh mozzarella, are not suitable for freezing. They are more likely to form ice crystals, and their flavour may be compromised. Soft, ripened cheeses like brie, Camembert, and Muenster should be enjoyed fresh and can be ripened in the refrigerator. Freezing blue cheese is also not recommended, as low temperatures can damage the moulds necessary for the ripening process.

While freezing can extend the shelf life of cheese, it is important to note that it alters the texture significantly. Therefore, frozen cheese is best suited for cooked dishes where changes in texture are less noticeable, such as sauces, pizza, or grilled cheese sandwiches.
