Cheese Storage: How Long Can You Keep Cheese Unrefrigerated?

Cheese is a staple in many households, but how long can it be left out of the fridge before it goes bad? The answer depends on several factors, including the type of cheese, how it's made, and how fresh it is. Hard cheeses like cheddar and parmesan can last longer at room temperature than soft cheeses like mozzarella or cream cheese due to their lower moisture content. The U.S. Department of Health recommends not leaving perishable foods, including soft cheeses, unrefrigerated for more than two hours. Harder cheeses can be left out for up to four hours but should be checked for signs of spoilage. Proper storage is crucial, and cheese should be wrapped in parchment paper, cheesecloth, or beeswax wrap rather than plastic wrap to allow it to breathe.

Hard cheeses can be left out of the fridge for longer than soft cheeses

The length of time cheese can be left out of the fridge depends on its moisture content. Harder cheeses like cheddar, Parmesan, or Gruyere are aged longer and have lower moisture content, making them less susceptible to bacterial growth. On the other hand, softer cheeses like mozzarella, cream cheese, cottage cheese, or feta have higher moisture content, making them more perishable.

The aging process also plays a role in how long cheese can be left out. Hard cheeses are aged longer, sometimes between two and 36 months, which contributes to their lower moisture content. During the cheesemaking process, most of the whey is removed from the curds, further reducing moisture. These cheeses are then either brined or waxed, contributing to their longer shelf life.

Additionally, the storage method can impact how long cheese can be left out. Proper storage allows the cheese to breathe and release moisture while protecting it from low humidity. For example, soft cheeses sold in brine, like feta or fresh mozzarella, should be kept in their liquid with a secure lid. Blue cheese can be wrapped in foil, while soft-ripened cheese like Brie should be wrapped in cheese paper or parchment paper and kept in an airtight container.

In summary, hard cheeses can be left out of the fridge for longer than soft cheeses due to their lower moisture content and longer aging process. However, it's important to consider other factors such as storage method and temperature to ensure the cheese remains safe and maintains its quality.

Soft cheeses should be discarded after two hours at room temperature

Soft cheeses are more perishable than hard cheeses. They have a higher moisture content, which creates more opportunities for bacteria to grow, making them much more perishable and susceptible to spoilage. This is why soft cheeses should be discarded after two hours at room temperature.

The U.S. Department of Health advises against keeping perishable food out of the fridge for more than two hours, and soft cheeses, such as cottage, cream cheese, brie, or fresh mozzarella, fall into this category. These cheeses are not aged and have a higher moisture content, making them highly perishable.

Leaving soft cheeses out for longer than two hours increases the risk of bacterial growth and spoilage, which can lead to foodborne illnesses. Even if the cheese looks and smells fine, there may be harmful bacteria present that could cause health issues. Therefore, it is recommended to discard soft cheeses that have been left out at room temperature for more than two hours as a precautionary measure.

Additionally, the quality and taste of soft cheeses can deteriorate quickly at room temperature. They are more delicate and creamy, and their texture and flavour can be negatively impacted by higher temperatures. Soft cheeses are meant to be stored in their natural liquid in a refrigerator to maintain their freshness and best taste.

In summary, soft cheeses should be treated as perishable food and kept refrigerated. When left out at room temperature, they should be discarded after two hours to prevent potential health risks and maintain the best quality and taste.

Hard cheeses can be left out for up to four hours

Hard cheeses, such as cheddar, Gruyere, and Parmesan, can be left out of the fridge for up to four hours. These cheeses are aged for longer periods, which results in a lower moisture content and a distinct, crumbly texture. This makes them less susceptible to bacterial growth and less perishable than soft cheeses.

Hard cheeses are made by removing most of the whey from the curds during the cheesemaking process, which removes a lot of the moisture. They are then either brined to create a hard rind or waxed and aged for between two and 36 months, or even longer. The longer ageing process also contributes to their longer life out of the fridge.

While hard cheeses can be left out for up to four hours, it is still important to check for signs of spoilage before consuming them. These signs can include an unpleasant smell, a slimy surface, dark spots, dryness, cracks, or mould. If any of these signs are present, the cheese should be discarded. If not, the cheese can be rewrapped and put back in the fridge.

It is worth noting that while hard cheeses can be left out of the fridge for longer than softer cheeses, their quality and taste may still be impacted. For the best results, hard cheeses should be stored in the refrigerator, wrapped in parchment paper, cheesecloth, butcher paper, cheese storage bags, or beeswax wrap.

The longer cheese is left out, the more its quality and taste will be affected

Cheese is a perishable food, and like all perishable foods, it is recommended that it should not be left unrefrigerated for more than two hours. However, this duration is not a hard-and-fast rule and depends on various factors, including the type of cheese, moisture content, temperature, and surface area.

Hard cheeses, such as cheddar, Swiss, and Parmesan, can typically be left out longer than soft cheeses. This is because hard cheeses have a lower moisture content, which makes them less susceptible to bacterial growth. They also have a lower pH, making them more acidic and therefore safer to store at higher temperatures. However, even hard cheeses should not be left out for more than four hours, as the quality and taste may begin to differ.

Soft cheeses, on the other hand, are more perishable and should not be left out for more than two hours. These include cheeses such as cottage cheese, cream cheese, Brie, Camembert, and fresh mozzarella. They have a higher moisture content, creating more opportunities for bacteria to grow.

Additionally, the surface area of the cheese matters. Shredded or sliced cheese has a larger surface area relative to volume, making it more easily compromised than a block of cheese. Therefore, it is essential to inspect these closely when left out for an extended period.

The temperature at which the cheese is stored also plays a crucial role in its longevity. At higher temperatures, cheese can quickly degrade in quality, even within eight hours. On the other hand, at a cooler temperature of around 55°F (12°C), cheese can last for a very long time, even years, without going bad.

In summary, the longer cheese is left out, the higher the chances of bacterial growth and spoilage. Therefore, it is essential to follow the recommended guidelines for storing cheese to maintain its quality, flavour, and safety.

Cheese should be stored in parchment paper, cheesecloth, butcher paper, cheese storage bags, or bees wrap

The proper storage of cheese is essential for maintaining its shelf life, flavour, and quality. While refrigeration is a common method to keep cheese fresh, it is not the only option. One recommended alternative is to store cheese in parchment paper, cheesecloth, butcher paper, cheese storage bags, or bees wrap.

Storing cheese in parchment paper or butcher paper involves wrapping the cheese tightly to prevent it from drying out and becoming hard. This method is particularly useful for hard and semi-hard cheeses. Parchment paper or butcher paper helps regulate moisture, ensuring the cheese does not dry out while also allowing it to "breathe." This type of wrapping is then placed in a resealable bag to further preserve freshness and prevent the cheese from absorbing flavours from other foods in the refrigerator.

Cheesecloth is another option for storing cheese. Traditionally, cheesecloth was used to cover freshly pressed cheese rounds during the aging process, creating a breathable layer that allowed moisture to escape while also protecting the cheese from contaminants.

Cheese storage bags are specifically designed for this purpose and can be an effective way to store cheese. These bags are often made from breathable materials, such as cotton or paper, and may have a coating to prevent the cheese from drying out too quickly.

Bees wrap is a more recent innovation for food storage. It is made from cotton infused with beeswax, tree resin, and jojoba oil, creating a pliable and reusable wrap. Bees wrap provides a natural barrier that allows cheese to breathe while also protecting it from contaminants.

When using these storage methods, it is important to note that cheese should be stored in the refrigerator, ideally in the vegetable drawer, to maintain a cold and stable temperature with consistent humidity. Additionally, storing cheese in airtight containers can further prolong its freshness.

By utilising these storage methods, individuals can effectively preserve the quality and freshness of their cheese, ensuring it remains edible and enjoyable for a longer period, even without refrigeration.
