Cheese Storage: How Long Can You Keep Cheese Unrefrigerated?

There is much debate about whether cheese should be refrigerated or not. While some say that storing cheese in the fridge keeps it fresh for longer, others argue that it impacts the taste. The answer depends on the type of cheese. Some cheeses, like cottage cheese, ricotta, and mozzarella, need to be refrigerated. However, fresh mozzarella tastes better when served at room temperature. On the other hand, hard cheeses like cheddar, Swiss, and parmesan are fine to be stored outside the fridge.

Soft cheeses like Brie should be discarded after 2 hours

Soft cheeses, such as Brie, are more perishable than hard cheeses. This is because they contain more moisture, which makes them more susceptible to bacterial growth. Therefore, soft cheeses should be discarded after two hours at room temperature.

The two-hour guideline for perishable foods is widely recognised, and soft cheeses like Brie fall into this category. The U.S. Department of Health advises against keeping perishable foods out of the fridge for more than two hours. This is especially important for soft cheeses like Brie, Camembert, and fresh mozzarella.

Leaving soft cheeses out at room temperature for longer than two hours increases the risk of bacterial growth and spoilage. While it may not always lead to a food safety issue, there is a potential risk of pathogens or mould. If mould is visible on soft cheese, it should be discarded immediately.

To maintain the quality and safety of soft cheeses, it is essential to follow proper storage practices. Soft cheeses should be kept refrigerated, ideally below 5°C, to ensure they remain safe to consume and prolong their shelf life. When serving, it is recommended to take the cheese out of the fridge about an hour beforehand to bring it to room temperature and enhance its flavour and texture.

In summary, soft cheeses like Brie are best enjoyed within two hours of being left out of the fridge. To ensure food safety and maintain optimal taste, it is crucial to adhere to the recommended guidelines for storing and serving cheese.

Hard cheeses like Cheddar can be left out for longer

However, it is important to note that leaving cheese out for too long can impact its quality. Hard cheeses may become drier and lose their flavour, so it is best to place any leftover cheese back in the fridge as soon as possible.

If you are unsure whether your hard cheese is safe to eat, there are some signs to look out for. Firstly, check for mould—if there is mould on the cheese, throw it out immediately. You can also give the cheese a quick smell check and look for any changes in texture. If the cheese has dried out, it can be wrapped in foil and stored in the freezer for later use in recipes.

To maintain the quality of your hard cheese, it is recommended to store it in the fridge at a temperature between 34ºF and 38ºF (1ºC and 3ºC). When you are ready to eat the cheese, take it out of the fridge about an hour beforehand to bring it to room temperature and enjoy its full flavour.

Fresh cheeses like Mozzarella should be chilled until serving

Fresh cheeses like mozzarella have a high moisture content, and therefore need to be kept in the fridge. Leaving them unrefrigerated for too long can cause bacterial growth and spoilage. According to experts, perishable foods, including soft, fresh cheeses like mozzarella, should not be left unrefrigerated for longer than two hours. After four hours, harmful bacteria can start to multiply, and the cheese may no longer be safe to eat.

Mozzarella is best kept in the fridge until serving. If you want to improve its flavour, you can take it out of the fridge about 20-30 minutes before serving. This will allow the cheese to reach room temperature and improve its texture and flavour. However, it's important not to leave it unrefrigerated for too long.

If you're travelling with fresh mozzarella, it's best to keep it in a cooler with ice or ice packs. This will ensure that the cheese remains cold, which is crucial for food safety. If you're unable to keep the mozzarella cold during travel, it's recommended to discard it after four hours at room temperature.

To maximise the shelf life of fresh mozzarella, it's important to store it properly. After opening, wrap the original packaging tightly in plastic wrap or aluminium foil. For even better results, wrap the cheese first in wax or parchment paper and then cover it with plastic wrap before refrigerating. Properly stored, fresh mozzarella will last about one to two weeks in the refrigerator.

If you want to extend the shelf life of fresh mozzarella, you can freeze it. Cut the cheese into portions no larger than half a pound each, and wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. Frozen cheese may become crumbly and lose some of its flavour, so it's best suited for cooked dishes like sauces, soups, and casseroles.

Perishable foods should be thrown out after 2 hours

Perishable foods, including soft cheeses such as cottage cheese, cream cheese, ricotta, mascarpone, and mozzarella, should be thrown out after two hours at room temperature. This is because soft cheeses have higher moisture content, making them more susceptible to bacterial growth and spoilage. The same goes for soft, unripened cheeses like cottage and cream cheese, as well as fresh soft cheeses like queso fresco, and soft ripened cheeses like brie, camembert, and fresh mozzarella.

While hard cheeses like cheddar, parmesan, or gouda can be left out for longer, it is still recommended to discard them after two hours to ensure food safety. Hard cheeses are less perishable due to their lower moisture content and reduced risk of bacterial growth. They can be rewrapped and put back in the fridge if left out for a shorter time, but it is not advisable to leave them out for an entire day.

To maintain food safety and optimal flavour, it is best to follow the two-hour guideline for perishable foods and store cheese in the fridge. However, if you plan to consume the cheese within two hours, it is recommended to take it out of the fridge about 20 to 30 minutes beforehand to bring it to room temperature, enhancing its flavour and texture.

In summary, to prevent food waste and potential food safety issues, it is crucial to monitor the time perishable foods, including soft cheeses, spend outside the fridge and adhere to the two-hour guideline. Hard cheeses have more flexibility but should still be treated with caution if left out for extended periods.

Waxed cheese can be left out for 24 hours

The length of time that cheese can be left out of the fridge depends on several factors, including the type of cheese, how it was made, and how fresh it is. In general, soft cheeses with high moisture content, such as cottage cheese, ricotta, and mozzarella, are more perishable and should be discarded if left out for more than two hours. Harder cheeses with lower moisture content, like cheddar, Swiss, and Parmesan, can be left out for longer, but it is still recommended to rewrap and refrigerate them after four hours.

Now, let's specifically talk about waxed cheese. Waxed cheese, typically hard cheeses like Parmesan or Gruyere, can be left out of the fridge for extended periods. The wax coating acts as a protective barrier, preventing bacterial growth and helping to maintain the cheese's excellent taste and texture. Some sources suggest that hard waxed cheeses can be safely left out at room temperature for up to 24 hours without spoilage. However, it is important to note that the longer the cheese is left out, the more its quality, taste, and texture may be affected.

The Cheshire Cheese Company, for example, states that their waxed cheese truckles have a best-before date of up to four months, but they emphasize that the cheese will last considerably longer if stored in the fridge. They also mention that their waxed cheeses can be left out of the fridge for short periods, but for extended storage of more than a day or so, they recommend refrigeration.

So, while it may be safe to leave waxed cheese out for 24 hours, it is always a good idea to check for signs of spoilage before consuming it. Additionally, proper storage is crucial to maintaining the quality and longevity of your cheese.
