Cheese is a beloved food item, but it doesn't always last forever in the fridge. The shelf life of cheese depends on various factors, such as moisture content, storage methods, and the type of cheese. Soft cheeses like ricotta, feta, and mozzarella have a shorter shelf life, typically lasting one to two weeks in the fridge. On the other hand, hard cheeses like cheddar, parmesan, and gouda have lower moisture content, extending their shelf life to several months, and even up to a year when stored in the fridge. Proper storage methods, such as wrapping cheese in wax or parchment paper and maintaining a safe fridge temperature below 40°F (4°C), can help extend the life of cheese. Additionally, factors like mold, smell, and taste can indicate when cheese has gone bad.

What You'll Learn
Soft cheeses last 1-2 weeks in the fridge
Soft cheeses, such as mozzarella, burrata, feta, cottage cheese, cream cheese, brie, and Camembert, are more delicate and creamy, with a higher moisture content than hard cheeses. This means they have a shorter shelf life and should be consumed within 1-2 weeks of opening. Fresh cheeses like ricotta and cottage cheese have an even shorter shelf life and are best consumed within a week or two of opening.
Soft cheeses are more perishable and should be stored in the refrigerator, with a safe fridge temperature of below 40°F (4°C). They should be wrapped in wax, parchment, or cheese paper to help maintain their moisture and stored in the vegetable drawer of the refrigerator, where the temperature is cold and stable with consistent humidity.
It is important to note that soft cheeses are more susceptible to mould, and if mould is visible, the entire block should be discarded, even if the mould is only on a small portion. Signs of spoilage in soft cheeses include a sweaty, chlorine-like, or ammonia-like odour, a slimy surface, dark spots, dryness, or cracks.
To maximise the shelf life of soft cheeses, it is recommended to purchase them in smaller quantities and consume them within 1-2 weeks of opening. Additionally, proper food handling, storage, and sanitation practices should be followed to ensure the safety and quality of the cheese.
In summary, soft cheeses typically last 1-2 weeks in the fridge after opening. However, it is important to inspect the cheese for any signs of spoilage and follow proper storage guidelines to ensure its quality and safety.

Hard cheeses can last years in the fridge
Hard cheeses, such as cheddar, parmesan, and gouda, can last for years in the fridge, especially if vacuum-packed and kept at a temperature below 40°F (4°C). Hard cheeses have a lower moisture content, which inhibits bacterial growth and increases their longevity. They can even be left out of the fridge for up to four hours without becoming unsafe, although their quality and taste may deteriorate.
Hard cheeses are significantly more durable than soft cheeses, which typically last only one to two weeks in the fridge after opening. Soft cheeses have a higher moisture content, creating a more favourable environment for bacterial growth and making them more perishable. Unlike hard cheeses, soft cheeses should be discarded if left unrefrigerated for more than two hours.
While hard cheeses can endure, they are not immune to spoilage. Over time, they may develop an unpleasant smell, slimy surface, dark spots, dryness, cracked areas, or mould. If mould is present, it is recommended to cut off at least 1 inch (2.5 cm) around and below the affected areas before consuming the remainder of the cheese.
To maximise the lifespan of hard cheeses, proper storage is essential. After opening, remove the cheese from its plastic packaging and wrap it loosely in a breathable material such as wax, parchment, or cheese paper. Then, place the cheese in a container with an airtight lid and store it in the refrigerator. With proper storage and refrigeration, hard cheeses can retain their quality and edibility for extended periods.

Safe fridge temperature is below 40°F (4°C)
To ensure cheese stays fresh for as long as possible, it is important to maintain a safe temperature in your fridge. The ideal temperature is below 40°F (4°C). At this temperature, you can expect soft cheeses to last 1-2 weeks in the fridge after opening, while most hard cheeses will last 3-4 weeks. Hard cheeses generally don't require refrigeration but will keep longer if stored in the fridge.
To monitor the temperature of your fridge, you can purchase a fridge thermometer and place it in the warmest spot, usually near the door. This will allow you to ensure that your fridge is consistently maintaining a safe temperature for your cheese and other perishables.
Proper wrapping and storage techniques are also crucial to prolonging the life of your cheese. After opening, wrap cheese in wax, parchment, or cheese paper to help maintain its moisture. Avoid using tight, non-porous materials like plastic wrap, as they can dry out the cheese and harden it. Instead, opt for porous wrapping materials that allow the cheese to breathe.
Additionally, it is important to store cheese in the appropriate location within the fridge. Place the cheese on the top or middle shelf, or in a drawer, ensuring it is above raw meats, poultry, and fish to avoid contamination.
By maintaining a safe fridge temperature below 40°F (4°C) and employing proper wrapping and storage practices, you can maximize the shelf life of your cheese and minimize the risk of premature spoilage.

Wrapping cheese in plastic can dry it out
When storing cheese in the fridge, it is important to wrap it properly to maintain its moisture and freshness. While plastic wrap may seem like a convenient option, it can actually dry out the cheese and affect its quality.
Cheese is a perishable dairy product that requires proper storage to prolong its shelf life. When exposed to air, cheese can quickly dry out, leading to a harder texture and a decrease in overall quality. Therefore, it is essential to wrap it properly before storing it in the fridge.
Wrapping cheese in plastic can accelerate the drying process due to the non-porous nature of plastic wrap. Plastic wrap forms a tight barrier around the cheese, trapping moisture inside. This trapped moisture can then be absorbed by the cheese, causing it to dry out faster. Additionally, plastic wrap can restrict airflow, hindering the cheese's ability to breathe.
To prevent cheese from drying out, it is recommended to use porous wrapping materials such as wax paper, parchment paper, or cheese paper. These materials allow the cheese to breathe while maintaining optimal moisture levels. They provide a protective barrier without sealing in moisture completely. By using these alternative wrapping options, you can help maintain the texture and freshness of the cheese for a longer period.
It is worth noting that different types of cheese have varying moisture contents, and some may be more susceptible to drying out than others. Soft cheeses, for example, tend to have higher moisture content and can dry out more quickly. Therefore, proper wrapping and storage are crucial to preserving the quality of the cheese.

Soft-ripened cheese needs more care than other soft cheeses
Soft-ripened cheese is characterised by a creamy texture and a bloomy rind. It is produced by adding moulds and cultures to the curd, which then ripens from the outside in. This process results in three distinct layers: the rind, the paste, and the creamline. The creamline is formed through proteolysis, where moulds break down proteins in the cheese, creating a gooey layer.
Soft-ripened cheeses include classics such as Brie and Camembert, as well as other varieties like Epoisses, Livarot, Pont L'eveque, and Munster. These cheeses are known for their earthy, mushroomy flavours, which intensify as they mature. However, some soft-ripened cheeses, like Saint André, have a butterier and more lactic taste.
Due to their high moisture content, soft-ripened cheeses require more careful handling than other soft cheeses. They are more perishable and have a shorter shelf life. Once opened, soft cheeses typically last only 1–2 weeks in the fridge, while hard cheeses can last 3–4 weeks. To extend its lifespan, soft-ripened cheese should be wrapped in wax paper and then loosely in plastic wrap before refrigeration. This prevents the cheese from drying out while allowing it to breathe, as suffocating the cheese will kill the beneficial enzymes, bacteria, and moulds.
It is important to inspect soft-ripened cheese for signs of spoilage. Soft cheeses should be discarded if they develop mould, unlike hard cheeses where the mouldy part can be cut off. A strong ammonia smell is a sign that the cheese has passed its prime and should be discarded. However, some people enjoy the unique flavour profile of older cheeses, even with their unctuous, funky characteristics.
