Cheese's Fridge Life: How Long Does It Last?

Cheese is a beloved staple in many households, but it's important to know how long it can be left out of the fridge before it spoils. The answer depends on several factors, including the type of cheese, the temperature of the room, and how the cheese is made. In general, soft cheeses with higher moisture content, such as mozzarella, cream cheese, and ricotta, are more perishable and should not be left out for more than two hours. Harder cheeses with lower moisture content, such as cheddar, Parmesan, and Gouda, can last a little longer, up to four hours, but even these cheeses will start to dry out and lose their appeal if left out for too long.

Soft cheeses spoil faster than hard cheeses

The U.S. Department of Health does not recommend keeping perishable food out of the fridge for more than two hours. This is especially true for soft cheeses, which should be discarded if left out for longer than two hours. Harder cheeses, such as cheddar, Parmesan, or Gouda, can be left out for up to four hours and then rewrapped and put back in the fridge.

The length of time a cheese can be left out also depends on its texture. The four main categories of cheese texture are hard, semi-hard, semi-soft, and soft. Hard cheeses, such as Parmesan and Gruyere, are aged longer and have a lower moisture content due to the removal of most of the whey during the cheesemaking process. Semi-hard cheeses, like cheddar and Swiss, have a slightly softer texture but are still firm enough to be sliced or grated. Semi-soft cheeses have a higher moisture content and a short aging process, while soft cheeses have the highest moisture content and are not aged.

In addition to texture, other factors that affect how long a cheese can be left out include how the cheese is made and how fresh it is. Proper storage is also important, as wrapping cheese too tightly can reduce its quality and flavour.

Hard cheeses can be left out for up to 8 hours

Leaving cheese out of the fridge for too long can be risky. The US Department of Health recommends that perishable food should not be left out of the fridge for more than two hours. However, this guideline is flexible when it comes to hard cheeses.

Hard cheeses, such as cheddar, Gruyere, and Parmesan, can be left out at room temperature for up to eight hours. This is because they have a lower moisture content, which makes them less susceptible to bacterial growth. Their longer aging process also contributes to their longer life out of the fridge.

While hard cheeses can withstand being out of the fridge for a longer period, it's important to consider the temperature of the room. An ordinary room temperature of around 70 degrees Fahrenheit is generally safe. However, if the room is warmer, it's best to reduce the time the cheese is left out.

Additionally, while hard cheeses can be left out for an extended period, it's crucial to monitor their quality. Hard cheeses may start to dry out and separate, affecting their texture and appearance. Therefore, it is recommended to wrap them well and refrigerate them if they have been out for more than four hours.

To summarise, hard cheeses can be safely left out of the fridge for up to eight hours, but it's important to consider factors like room temperature and the quality of the cheese to ensure it remains safe and appetising.

Soft cheeses can be left out for 2-4 hours

Soft cheeses, such as mozzarella, cream cheese, cottage cheese, and brie, are more perishable than harder cheeses. They have a higher moisture content, which makes them more susceptible to bacterial growth and spoilage. Therefore, it is recommended that soft cheeses be left out of the fridge for a maximum of 2-4 hours.

The U.S. Department of Health advises against keeping perishable food out of the fridge for more than two hours. Soft cheeses fall into this category and should be discarded if left out for longer than two hours. This is because they have a higher moisture content and are typically not aged, making them more perishable and prone to bacterial growth.

However, it is important to note that the spoilage of soft cheese is unlikely to cause food poisoning. The bacteria that cause spoilage are different from those that cause food poisoning. While spoilage bacteria can alter the colour, flavour, texture, and aroma of cheese, they are not pathogenic and will not make you sick.

Leaving soft cheese out at room temperature for an extended period may result in a loss of quality due to drying out and the separation of fat from the cheese. Soft cheeses are best stored in their natural liquid in a plastic container in the refrigerator.

To ensure food safety and maintain the quality of soft cheeses, it is advisable to follow the recommended guidelines and store them properly.

Cheese can be safely stored in the fridge for several months

Cheese is a beloved staple in many households, but it's important to know how long it can be safely stored outside of the fridge. The answer depends on various factors, including the type of cheese, the temperature of the room, and the length of time it's left out.

Soft cheeses, such as mozzarella, cream cheese, cottage cheese, and ricotta, are more delicate and perishable due to their higher moisture content. They should be consumed within a few hours of being left out, typically lasting 2 to 4 hours at room temperature. Leaving them unrefrigerated for longer increases the risk of spoilage and bacterial growth, making them unsafe to consume.

On the other hand, hard cheeses like cheddar, Parmesan, and Gruyere have a lower moisture content, which makes them less susceptible to bacterial growth. These varieties can be left out of the fridge for extended periods, typically up to 8 hours, without posing a health risk. However, it's important to note that the quality and taste of the cheese may start to deteriorate after a few hours, as the fat can begin to separate and the cheese may dry out.

When it comes to storing cheese in the fridge, it can prolong its shelf life significantly. Properly stored cheese can last for several months in the refrigerator. For example, unopened blocks of hard cheese can last for up to 6 months, while soft cheeses can last for 1 to 2 weeks after opening. It's important to note that the type of cheese, quality control issues, and storage methods can also impact their longevity.

To maintain the freshness of cheese in the fridge, it's recommended to wrap it gently in parchment paper or store it in cheese bags, which provide humidity and allow the cheese to breathe. Freezing cheese is generally not recommended, especially for soft varieties, as it can affect their texture and taste.

In summary, while cheese can be safely left out of the fridge for varying durations depending on its type, storing it in the fridge will greatly extend its shelf life. With proper storage, cheese can be enjoyed for several months, ensuring both its quality and safety.

Cheese should be wrapped in parchment paper, not plastic wrap

Cheese is a staple in many households, but it can be tricky to keep it fresh. While plastic wrap is commonly used to store food, it's not ideal for cheese. Here's why cheese should be wrapped in parchment paper instead:

Cheese Needs to Breathe

Cheese is a living thing, full of active microorganisms that need to breathe. Plastic wrap suffocates the cheese, reducing its quality and flavour. On the other hand, parchment paper is porous and allows for airflow, keeping those good microorganisms alive.

Plastic Wrap Can Alter the Taste of Cheese

Plastic wrap can cause cheese to taste like plastic, which is definitely not what you want. Parchment paper, on the other hand, is coated with wax and polyethylene, creating a barrier that prevents the cheese from tasting like anything other than cheese.

Parchment Paper is Better for the Environment

Plastic wrap is typically made from polyvinylidene chloride (PVdC) or low-density polyethylene (LDPE), both of which are not great for the environment. Parchment paper, on the other hand, is more eco-friendly and can even be composted in some cases.

Parchment Paper is Easier to Work With

If you've ever tried to wrap cheese in plastic wrap, you know it can be a frustrating experience. Parchment paper, on the other hand, is easier to work with and can be securely wrapped around the cheese without the need for fancy folding techniques.

Parchment Paper Helps Regulate Moisture

Cheese needs to breathe, but it also needs to maintain the right level of moisture. Parchment paper is designed to wick away excess moisture while still allowing some moisture to remain, keeping your cheese from drying out.

Parchment Paper is Reusable

Not only is parchment paper great for initial storage, but it can also be reused for at-home storage. Simply rinse and dry the paper after you finish a block of cheese, and it's ready to be used again. This helps reduce waste and saves you money in the long run.
