Parmesan Cheese: How Long Does It Last Unrefrigerated?

Parmesan cheese is a staple in kitchens around the world, and it's important to know how to store it to keep it fresh. While refrigeration is not necessary for food safety reasons, it is recommended to keep Parmesan cheese fresh for longer. So, how long will Parmesan cheese last unrefrigerated?

Unrefrigerated, unopened Parmesan can last for 1-1.5 years

Parmesan cheese is a staple in kitchens around the world and thankfully, it can be kept unrefrigerated and unopened for quite some time. Unrefrigerated, unopened Parmesan can last for 1-1.5 years. This is because Parmesan is a hard cheese with low moisture content, which means it has a longer shelf life than other types of cheese. The low moisture content prevents the growth of mold, so you don't have to worry about your Parmesan going bad quickly if left unrefrigerated.

However, it's important to note that this only applies to unopened Parmesan. Once the package has been opened, or if you have bought Parmesan wedges, it is recommended to wrap the cheese in parchment or wax paper and store it in a refrigerator or a cold, dark place to maintain its texture and flavour.

If you want to extend the shelf life of your Parmesan cheese even further, you can freeze it. Freezing Parmesan is a great option if you want to keep it for longer than the 1-1.5 years that it lasts unrefrigerated and unopened. However, freezing may affect the quality of the cheese, and it may lose some of its original flavour and texture.

When storing your Parmesan cheese, it is important to keep it in a cool, dry area. The ideal temperature range for storage is between 35°F and 45°F (2°C and 7°C). Additionally, make sure to wrap the cheese well in wax paper, aluminium foil, or a freezer bag to keep it fresh.

By following these storage tips, you can ensure that your unrefrigerated, unopened Parmesan cheese lasts for 1-1.5 years.

Opened, unrefrigerated Parmesan will last several months

Parmesan cheese is a staple in kitchens around the world, and it's good to know that when stored correctly, it can be kept fresh for a long time. While hard cheeses like Parmesan can be stored at room temperature, refrigeration will help extend their shelf life. However, it is not necessary to refrigerate Parmesan cheese for safety reasons, as it is a hard cheese. If you leave it at room temperature for a long time, you may notice that it will start to sweat as the fat from the cheese will begin to separate, and the texture will change.

If you have opened your Parmesan cheese and left it unrefrigerated, it should last several months before it goes bad. Always check the labels to confirm. The precise answer will depend on storage conditions—to maximize the shelf life of your Parmesan cheese, keep it in a cool, dry area. The best temperature for storage is between 37 degrees and 45 degrees Fahrenheit (2-7 degrees Celsius). This temperature range is ideal for preserving food without damaging it.

If your opened Parmesan cheese is stored in a cool, dry area, it will generally stay at the best quality for about 12 to 18 months at normal room temperature. If you bought your Parmesan in block form, the best way to store it is to wrap it well in wax paper, aluminium foil, or a zipper-lock bag and keep it refrigerated. You could also freeze it if you need to keep it for longer.

To cover your Parmesan cheese completely, you can use heavy-duty aluminium foil after covering it in wax paper. This will not only protect your cheese but will also allow it to breathe. When using aluminium foil, make sure to cover every part of the cheese.

Unrefrigerated Parmesan can be stored like in the supermarket

Parmesan cheese is a staple in kitchens around the world, and it's good to know that when stored correctly, it can be kept fresh and of optimal quality for a long time.

If you're looking to store unrefrigerated Parmesan cheese, it can be stored similarly to how it is stored in supermarkets. Commercially packaged grated Parmesan cheese, sold unrefrigerated, will usually last 12 to 18 months at normal room temperature. To maximise its shelf life, it should be kept in a cool, dry area.

The precise length of time that unrefrigerated Parmesan will last depends on the storage conditions. If you're looking to store it for an extended period, it's best to replicate the conditions of a cool, dry supermarket shelf. You can do this by keeping the cheese in a pantry or kitchen cupboard, away from heat sources such as ovens or radiators. Ensure the area is well-ventilated to prevent the cheese from becoming too warm or moist.

Additionally, you can extend the shelf life of unrefrigerated Parmesan by ensuring it is properly packaged. Parchment paper, cheese paper, or wax paper are ideal for wrapping the cheese, as they allow it to breathe and prevent condensation. Plastic wrap should be avoided, as it can cause the cheese to 'sweat' excessively. If using wax paper, you can further protect the cheese by covering it with a sheet of heavy-duty aluminium foil, ensuring every part is sealed.

By storing unrefrigerated Parmesan cheese in a cool, dry place and using appropriate packaging, you can maintain its quality and freshness for a significant period, similar to how it is stored on supermarket shelves.

Parmesan can be stored in wax paper, plastic paper, or aluminium foil

Parmesan cheese can be stored in wax paper, plastic paper, or aluminium foil. The key to properly storing Parmesan cheese is to maintain the right temperature and humidity levels, prevent exposure to moisture, and avoid contact with other foods to preserve its aroma.

Wax paper is a recommended option for wrapping Parmesan cheese. It helps retain moisture and prevents the cheese from drying out. This type of paper is lined with food-grade silicone, creating an effective barrier. After wrapping the cheese in wax paper, it is advisable to cover it with another layer, such as aluminium foil.

Aluminium foil provides additional protection for the cheese while still allowing it to breathe. It is important to ensure that all corners and gaps are covered with the foil. This combination of wax paper and aluminium foil helps maintain the quality of the cheese.

Some experts suggest that wrapping Parmesan cheese in plastic, such as plastic wrap or a plastic bag, is not ideal. Plastic can cause the cheese to "sweat" and may impact its breathability. However, the Italian Consortium, the producer of Parmesan cheese, recommends wrapping the cheese in plastic.

Regardless of the wrapping material used, it is crucial to store Parmesan cheese properly to maximise its shelf life. Unopened grated Parmesan cheese sold unrefrigerated can last for about 12 to 18 months at normal room temperature. However, for long-term storage, it is best to keep the cheese in a cool, dry area, preferably in the refrigerator.

Parmesan can be stored in the fridge for 6-20 weeks

Parmesan cheese is a staple in kitchens around the world, and it's good to know that when stored correctly, it can be kept fresh and tasty for a long time.

The first thing to know is that parmesan should always be refrigerated to keep it fresh and at its best quality for longer. If you bought it in block form, the best way to store it is to wrap it well in wax paper, aluminium foil, or a zipper-lock bag and keep it in the fridge. You can also freeze it if you need to keep it for longer, but its quality may decrease, and its original flavour and texture may be lost.

If you've opened a package of parmesan cheese or bought parmesan wedges, it is recommended to wrap the cheese in parchment or wax paper to allow it to breathe. Then, place it in the fridge or a cold, dark place. It is best to avoid using a tightly closed container as it will spoil, and it is also not recommended to leave the cheese uncovered.

The shelf life of parmesan cheese can vary depending on how it is stored. An unopened block of parmesan cheese will typically last from 6-18 months in the fridge. Once the package is opened, it should be consumed within 4 to 6 weeks. If you've damaged the original packaging or cut a piece of parmesan, you can keep it for 2-3 months wrapped in parchment or wax paper.

So, to summarise, parmesan can be stored in the fridge for 6-20 weeks, depending on whether it has been opened and how it is packaged.
