What You'll Learn
Vacuum-packed Parmigiano-Reggiano can be stored in the fridge for several months
Parmigiano-Reggiano is a hard cheese with a low water content, which means it can be stored for long periods of time. The best way to store it is to vacuum-pack it, which can extend its shelf life to several months.
Vacuum-packed Parmigiano-Reggiano should be stored in the refrigerator at a temperature of between 4 and 8°C. It is important to ensure that the package is sealed tightly and not exposed to the air, as this can cause the cheese to spoil and become mouldy.
Once the vacuum pack is opened, or if the cheese is purchased freshly cut, it must be stored in the refrigerator in a glass or plastic container, or wrapped in a food-grade plastic film or slightly damp cotton cloth. This will prevent the cheese from absorbing other odours in the refrigerator and ensure its humidity level remains optimal. Stored in this way, Parmigiano-Reggiano with a maturation of 12-18 months and a higher moisture content can be kept for about 15 days, while cheese with a maturation of 24 months or more can be kept for about a month.
To further extend the shelf life of Parmigiano-Reggiano, it can be frozen. However, freezing may affect the structure of the cheese's organoleptic characteristics, such as colour, flavour and texture.

Refrigerate at 4-8°C
Parmigiano-Reggiano cheese should be stored in the refrigerator at a temperature of 4–8°C. This temperature range is important to maintain the cheese's optimal quality. The refrigerator helps to preserve the cheese's aromatic characteristics and ensures its organoleptic features remain unchanged.
When storing Parmigiano-Reggiano, it is important to ensure the cheese is sealed and not exposed to air. Vacuum-packed Parmigiano-Reggiano can be stored in the refrigerator at 4–8°C for several months. The pack should have a “best before” date, but even after this date, the cheese will typically remain safe to use for up to a year, as long as it is properly stored.
If the cheese is freshly cut or no longer vacuum-packed, it should be stored in a glass or plastic container. It can also be wrapped in a food-grade plastic film or a slightly damp cotton cloth and then stored in the refrigerator. This will prevent the cheese from absorbing other odours and help maintain optimal humidity levels.
For a whole, unopened block of Parmigiano-Reggiano, the shelf life in the refrigerator is around seven to nine months. Once opened, the cheese will last for one to two months in the fridge. If mould appears on the surface, it can be removed with a knife, and the cheese can still be enjoyed.

Store in glass or plastic containers
When storing Parmigiano-Reggiano cheese in the refrigerator, it is best to use airtight glass or plastic containers. This type of packaging will help to regulate moisture and prevent the cheese from drying out or becoming moldy. The container should be large enough to accommodate the cheese without crowding, allowing for some air circulation. Puncture small holes in a plastic wrap or bag to allow the cheese to breathe if you don't have a container.
It is recommended to wrap the cheese in a piece of wax or parchment paper before placing it in the container. This will help to absorb any excess moisture and prevent the cheese from becoming soggy. The paper should be changed regularly, especially if it becomes damp. You can also add a paper towel to the container to absorb any excess moisture and help maintain the right level of humidity.
Additionally, always store Parmigiano-Reggiano cheese in the coldest part of the refrigerator, which is usually the back or bottom shelf. This will help to maintain a consistent temperature and maximize the shelf life of the cheese. The ideal temperature for storing cheese is between 35°F to 45°F (2°C to 7°C).
Furthermore, when storing Parmigiano-Reggiano cheese, it is important to avoid strong-smelling foods such as onions, garlic, and fish. This is because the cheese has a strong affinity for absorbing odors, and unpleasant smells can be absorbed, affecting the flavor of the cheese. Also, ensure that the refrigerator is clean and free of odors to prevent any unwanted flavors from affecting the cheese.
Finally, properly stored Parmigiano-Reggiano cheese can last for several weeks to a few months in the refrigerator. Regularly check the cheese for any signs of mold or drying and consume it within the recommended storage period for the best quality and flavor. With proper storage, you can enjoy the rich, nutty flavor and hard, granular texture of Parmigiano-Reggiano cheese for a good length of time.

Wrapping in food-grade plastic film can extend shelf life
Parmigiano-Reggiano cheese is one of the best cheeses for lengthy preservation, thanks to its texture and low water content. However, the exact shelf life of a chunk of Parmigiano-Reggiano cheese depends on its storage conditions. To maximise the shelf life of this cheese, it is important to wrap it tightly in food-grade plastic film 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.
When stored in the refrigerator, Parmigiano-Reggiano cheese should be kept at a temperature ranging from 4°C to 8°C. It is important to ensure that the cheese is stored in a sealed and intact package, with no exposure to air. This will help prevent the cheese from becoming mouldy. In addition, Parmigiano-Reggiano cheese should be stored separately from other foods, as the fatty part of the cheese can absorb other smells present in the refrigerator.
By wrapping Parmigiano-Reggiano cheese in food-grade plastic film, you can extend its shelf life significantly. This type of plastic film creates a barrier that helps to maintain optimal humidity levels and prevents the cheese from drying out. It also protects the cheese from absorbing other odours or flavours present in the refrigerator. The plastic film acts as a physical barrier, keeping the cheese fresh and flavourful for a longer period of time.
It is important to note that the effectiveness of food-grade plastic film in extending the shelf life of Parmigiano-Reggiano cheese depends on the quality and integrity of the wrap. It should be wrapped tightly around the cheese, with no gaps or holes, to ensure that moisture and air are kept out. Additionally, it is crucial to periodically check the condition of the cheese to ensure that no mould has developed. If mould is present, it can be safely removed using a knife, and the cheese can be re-wrapped in fresh food-grade plastic film.
While food-grade plastic film can extend the shelf life of Parmigiano-Reggiano cheese, it is not the only option for storage. Glass or plastic containers can also be used to store the cheese and maintain its quality. It is recommended to avoid using film, as it can compromise the original humidity level of the cheese. Instead, wrapping the cheese in a slightly damp cotton cloth before placing it in a container can help maintain optimal humidity levels.

Opened Parmigiano-Reggiano can last up to 2 weeks to 1 month
Parmigiano-Reggiano is a hard cheese with a low water content, which means it can be stored for long periods. However, once the cheese has been exposed to air, its longevity is reduced.
To maximise the shelf life of opened Parmigiano-Reggiano, it is recommended to wrap the cheese tightly in plastic wrap or aluminium foil. For even better results, wrap the cheese first in wax or parchment paper and then cover with plastic wrap before refrigerating.
It is important to note that Parmigiano-Reggiano should be stored in the refrigerator at all times to maximise its shelf life. The ideal temperature range is between 4 and 8°C.

Yes, Parmigiano-Reggiano can be frozen, although it may alter the structure of the cheese's organoleptic characteristics such as colour, flavour, and texture. To freeze, cut the cheese into portions, wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them in an airtight container or freezer bag. Frozen Parmigiano-Reggiano can last for about 10 to 12 months, but will remain safe beyond that.
