Cheese Lifespan: How Long Does It Last Unrefrigerated?

How long your cheese lasts depends on the type of cheese, the temperature of the room, and whether it's raw or pasteurised. Soft cheeses like Brie, cottage cheese, and mozzarella are more perishable and shouldn't be left out for more than two hours. Harder cheeses like cheddar, Swiss, and Parmesan can be left out for up to four hours and waxed truckles can be left unrefrigerated for up to 24 hours. Pasteurised cheese can be left out for days without making you sick, but it won't look its best.

Soft cheeses like mozzarella, cream cheese, and cottage cheese should be discarded after two hours

Soft cheeses, such as mozzarella, cream cheese, and cottage cheese, are more perishable than harder cheeses. This is because they have a higher moisture content, are not ripened or aged, and are more susceptible to bacterial growth. Therefore, it is recommended that these cheeses are discarded after being left out at room temperature for two hours.

The U.S. Department of Health advises that perishable foods should not be left out of the fridge for more than two hours. Soft cheeses, such as mozzarella, cream cheese, and cottage cheese, fall into this category. These cheeses are often sold without a rind, which acts as a protective barrier against bad bacteria and mould. Without this protective layer, soft cheeses are more vulnerable to spoilage.

Leaving soft cheeses out at room temperature for an extended period can impact their quality, taste, and safety. They may become dry, crumbly, or develop a rubbery texture. Additionally, their high moisture content can encourage bacterial growth, increasing the risk of foodborne illnesses.

To ensure food safety and maintain the best quality, it is advisable to keep soft cheeses refrigerated and only bring them to room temperature shortly before serving. This allows the fat molecules in the cheese to relax, enhancing the flavour and texture. However, even at room temperature, soft cheeses should not be left out for more than two hours to minimise the risk of spoilage and foodborne illnesses.

Proper storage practices, such as storing soft cheeses in their natural liquid in a plastic container, can also help extend their shelf life and preserve their quality.

Hard cheeses like cheddar, gouda, and parmesan can be left out for up to four hours

Hard cheeses, such as cheddar, gouda, and parmesan, can be left out of the fridge for up to four hours. This is because they have a lower moisture content, which makes them less susceptible to bacterial growth. However, it's important to note that while these hard cheeses can withstand being left out for longer than softer cheeses, their quality and taste may still be impacted.

The U.S. Department of Health advises against keeping perishable foods out of the fridge for more than two hours. Soft cheeses, like cottage cheese, cream cheese, brie, and fresh mozzarella, fall into this category of perishable foods and should be discarded if left unrefrigerated for longer than two hours.

Hard cheeses, on the other hand, can be left out for a little longer. If they've been out of the fridge for four hours or less, you can rewrap them and put them back in the fridge. After four hours, it's important to look for signs of spoilage, such as an unpleasant smell, a slimy surface, dark spots, dryness, cracks, or mold. If none of these signs are present, the cheese can be safely returned to the refrigerator.

The aging process also plays a role in how long cheese can be left out. Cheeses that are made from pasteurized milk and aged, such as cheddar, parmesan, gouda, and other hard cheeses, are less perishable due to their lower moisture content and higher acidity. These cheeses are also safer to consume at higher temperatures.

Additionally, the texture of the cheese matters. Semi-hard cheeses like cheddar have a slightly softer texture than hard cheeses but are still dense and firm enough to be sliced, grated, or cubed. Semi-soft cheeses, such as gouda, are softer and have a higher moisture content, making them more perishable.

When serving cheese, it's best to let it come to room temperature to enhance its flavour. This generally takes about 20-30 minutes for soft cheeses and an hour for harder cheeses like cheddar.

Pasteurized processed cheeses like American cheese can be left out for two hours

However, it's important to note that the two-hour guideline for leaving perishable food out does apply to cheese. After two hours, depending on the type of cheese, it may be safe to rewrap and refrigerate, but it's always best to check for signs of spoilage. Leaving cheese out for longer than two hours may not always pose a health risk, but it can change its quality, taste, flavor, and texture.

The U.S. Department of Health recommends not keeping any perishable food out of the fridge for more than two hours. This is definitely the case for soft cheeses like cottage cheese, cream cheese, brie, or fresh mozzarella. These cheeses have a higher moisture content and are not aged, making them more susceptible to bacteria and spoilage. Harder cheeses, on the other hand, like cheddar, Parmesan, or Gouda, can last a little longer, up to four hours, because they have a lower moisture content and are less likely to have bacterial growth.

The proper storage of cheese is crucial for its shelf life. Cheese needs to breathe, so wrapping it tightly in plastic wrap or a plastic bag is not ideal. Instead, try using parchment paper, cheesecloth, butcher paper, cheese storage bags, or beeswrap. Once wrapped, store the cheese in the refrigerator, where the temperature is cold and stable with consistent humidity.

Fresh soft cheeses like queso fresco, brie, and camembert should be discarded after two hours

Soft cheeses like queso fresco, brie, and camembert are more perishable than harder cheeses. This is because they have a higher moisture content, are not ripened, and are more susceptible to bacterial growth. Therefore, they should be discarded after being left out at room temperature for two hours.

The two-hour guideline for soft cheeses is supported by the U.S. Department of Health, which advises that perishable food should not be left out at room temperature for longer than two hours. This guideline is in place to prevent foodborne illnesses caused by bacterial growth.

While harder cheeses like cheddar, Parmesan, and Gouda have a lower moisture content and can be left out for longer, it is still recommended that they be discarded after four hours.

To ensure food safety and maintain the best quality and taste, it is important to follow these guidelines and properly store your cheese. Soft cheeses should be refrigerated and kept in their natural liquid in a plastic container.

When serving cheese, it is recommended to take it out of the refrigerator at least 20-30 minutes beforehand to bring it to room temperature, as this enhances the flavor and texture. However, leaving cheese out for too long can impact its quality, taste, and safety, especially for soft cheeses like queso fresco, brie, and camembert, which are more perishable.

Waxed truckles can be left unrefrigerated for up to 24 hours

The length of time that cheese can be left out of the fridge depends on several factors, including the type of cheese, the moisture content, and the temperature of the room. Soft cheeses with high moisture content, such as cottage cheese, cream cheese, and mozzarella, are more perishable and should be discarded if left unrefrigerated for more than two hours. Harder cheeses with lower moisture content, such as Cheddar, Parmesan, and Gouda, can be left out for longer—up to four hours—but should still be checked for signs of spoilage.

Waxed cheeses, such as truckles, can be left unrefrigerated for longer than other types of cheese. The wax coating helps to keep the cheese cooler for longer, inhibiting bacterial growth and spoilage. Therefore, waxed truckles can be left unrefrigerated for up to 24 hours and still taste incredible. After this period, it is recommended to store the cheese in the fridge to maintain its freshness and safety, especially if the wax has been cut or damaged.

When storing cheese in the fridge, it is important to wrap it properly to maintain its quality. Soft and semi-soft cheeses should be stored in their natural liquid in a sealed container. Hard and semi-hard cheeses should be wrapped in wax paper, cheese paper, or stored in a sealed container. The vegetable drawer of the refrigerator is ideal as it provides a cold and stable temperature with consistent humidity.

While waxed truckles can be left unrefrigerated for up to 24 hours, it is still important to handle them carefully. Keep them in a cool, dry place and avoid exposing them to extreme temperatures. Additionally, ensure that the wax is intact and has no cracks or damage, as this can compromise the quality and safety of the cheese.

In summary, waxed truckles can be safely enjoyed as part of a cheese board or gift without the need for immediate refrigeration. However, for optimal taste and longevity, it is best to store cheese in the fridge, especially if it will not be consumed within a day.
