Cheese is a staple in many households, but how long it can be left out of the fridge before it goes bad depends on several factors. The type of cheese is the most important factor, with hard cheeses like Cheddar and Parmesan lasting longer at room temperature than soft cheeses like Brie or Camembert. Other factors include how the cheese is made, how fresh it is, and the humidity of the environment. While leaving cheese out for more than two hours may not always pose a health risk, it can change in taste, flavor, quality, or texture.

Soft cheeses like mozzarella, Brie, Camembert, and cream cheese are more perishable and should be consumed within a week of opening
The length of time cheese lasts after opening depends on its type. Soft cheeses like mozzarella, Brie, Camembert, and cream cheese are more perishable and should be consumed within a week of opening.
Soft cheeses have the highest moisture content of all cheese types, ranging from grainy textures (like cottage cheese) to smooth and spreadable (like cream cheese). This high moisture content makes them more susceptible to bacterial growth and spoilage, so they should be consumed within a week of opening.
To maintain freshness and safety, soft cheeses should be stored in the refrigerator. If left out at room temperature, soft cheeses can spoil within two hours and should be discarded. Hard cheeses, such as cheddar and Parmesan, can be left out for longer periods but should still be refrigerated for optimal freshness.
When it comes to determining if a soft cheese has gone bad, it's important to inspect for any signs of spoilage, such as a bad smell, slimy surface, dark spots, dryness, cracks, or mould. Soft cheeses are particularly susceptible to mould, and even a small amount can render the entire product unsafe to eat. Therefore, it's crucial to inspect soft cheeses regularly and consume them promptly to prevent spoilage.
In summary, soft cheeses like mozzarella, Brie, Camembert, and cream cheese are highly perishable and should be treated with care. To ensure freshness and safety, these cheeses should be consumed within a week of opening and stored properly in the refrigerator. When in doubt, it's always best to discard the cheese to prevent any potential health risks associated with consuming spoiled food.

Hard cheeses like Cheddar, Parmesan, and Gouda can last three to four weeks after opening when stored properly
Hard cheeses, in general, have a longer shelf life than soft cheeses. This is because they contain less moisture and are therefore less prone to spoilage from bacterial growth. Specifically, hard cheeses like Cheddar, Parmesan, and Gouda can last three to four weeks after opening when stored properly.
Cheddar, Parmesan, and Gouda are all examples of hard, aged cheeses that are made from pasteurized milk. They have a more acidic pH, which also contributes to their longer shelf life. These types of cheeses are less likely to promote bacterial growth and can, therefore, last longer without refrigeration. However, it is important to note that while these hard cheeses can last a few weeks without refrigeration, they will last much longer if they are stored in a refrigerator.
To maximize the shelf life of these hard cheeses, it is recommended to wrap them tightly in plastic wrap or aluminum foil after opening. For even better results, wrap the cheese first in wax or parchment paper and then cover it with plastic wrap before refrigerating. Properly stored, a chunk of Gouda cheese will last for 2 to 3 weeks in the refrigerator. Cheddar and Parmesan cheeses will also benefit from this wrapping technique and can be expected to last a similar amount of time in the fridge.
If you accidentally leave hard cheeses like Cheddar, Parmesan, or Gouda out overnight, they might still be safe to eat. However, it is important to inspect them carefully for any signs of spoilage, such as discoloration, foul odours, or moisture. If you notice any of these issues, it is best to discard the cheese. Additionally, if you see any mould on the cheese, cut off at least 1 inch (2.5 cm) around and below the mouldy area and wrap the cheese again before placing it back in the refrigerator.

Fresh, unfermented cheeses like mozzarella, burrata, and ricotta will go bad and should be consumed before their best-by dates
Fresh, unfermented cheeses with higher moisture content, such as mozzarella, burrata, and ricotta, are more perishable and prone to bacterial growth if left unrefrigerated. These cheeses should be consumed promptly after opening and stored in the refrigerator to maintain their quality and safety.
Mozzarella, a soft and fresh cheese, is best kept in its original packaging with liquid, and any unused portions should be immersed in whey or an appropriate storage container. When stored properly in the refrigerator, mozzarella can be consumed within 3 days of opening, although some sources suggest it should be consumed immediately after opening.
Burrata, a type of cheese composed of a mozzarella sheath filled with thick cream and mozzarella curds, has a notoriously short shelf life. Once opened, it is recommended to consume burrata right away. Any leftover unopened burrata should be stored in its packing liquid in the refrigerator.
Ricotta cheese is another soft, unripened cheese with a high moisture content. Opened ricotta should be consumed within a few days to a week and stored in the refrigerator. If ricotta cheese has been open for longer than a month, it is likely no longer safe to consume, especially if it has developed a sour smell or taste, which indicates spoilage.
In summary, fresh, unfermented cheeses like mozzarella, burrata, and ricotta are highly perishable and should be treated with care to prevent spoilage. Proper storage in the refrigerator and prompt consumption are crucial to maintaining the quality and safety of these delicate cheeses.

Signs of spoilage in hard cheeses include a bad smell, slimy surface, dark spots, dryness, cracks, or mould
Hard cheeses like Cheddar, Parmesan, Gouda, and Swiss have a longer shelf life than soft cheeses. This is because they have a lower moisture content, which makes them less susceptible to spoilage from bacterial growth. However, even hard cheeses can spoil if not stored properly.
If you suspect that your hard cheese has spoiled, inspect its appearance, texture, and taste. If it has been sitting out for four hours or less, you can rewrap it and put it back in the fridge. Otherwise, carefully inspect it for any signs of spoilage. If you spot mould on hard cheese, you can cut off at least one inch (2.5 cm) around and below the mouldy spots. However, if you see red or black mould, discard the entire cheese, as some moulds are more dangerous than others.

Cheese should be wrapped in wax, parchment, or cheese paper and stored in the refrigerator to maintain its moisture
Cheese is a staple in many households, but it can be tricky to know how to store it properly. While it is possible to store cheese without refrigeration, it is generally recommended that cheese be wrapped in wax, parchment, or cheese paper and stored in the refrigerator to maintain its moisture and freshness.
Cheese is a fermented product, and the fermentation process, along with the addition of salt, acts as a natural preservative. Most cheeses do not "go bad" in the traditional sense, but rather continue to ripen and develop stronger flavours. Soft cheeses, such as Brie or Camembert, have a shorter life cycle and can quickly become runny and develop a strong ammonia smell if left unrefrigerated for too long. Hard cheeses, like Cheddar or Parmesan, have a lower moisture content and can generally be left out at room temperature for longer periods without spoiling, but their quality and taste may still be impacted.
To maintain the freshness and quality of cheese, it is best to wrap it tightly in wax, parchment, or cheese paper after opening. These types of paper help to regulate moisture, preventing the cheese from drying out while still allowing it to breathe. The wrapped cheese can then be placed in a plastic bag or airtight container and stored in the refrigerator. This method is particularly important for soft cheeses, which should be consumed within one week of opening. Hard, aged cheeses can last three to four weeks when stored properly.
It is worth noting that there are exceptions to these guidelines. Fresh, unfermented cheeses like mozzarella, burrata, and ricotta will go bad and should be consumed by their best-by dates. Additionally, while hard cheeses can be left out at room temperature for short periods, they will last longer and maintain their quality better if stored in the refrigerator.
In summary, to ensure the longevity and freshness of your cheese, it is best to wrap it in wax, parchment, or cheese paper and store it in the refrigerator. This practice will help maintain the cheese's moisture and flavour, regardless of its texture or variety.
