What You'll Learn
Wrapping: Use wax paper, cheese paper, parchment paper, or cheesecloth
Parmesan cheese is a hard cheese with a lengthy aging process. It has a long shelf life, but if you want to preserve it for longer, there are several ways to do so. One effective method is to wrap the cheese in wax paper, cheese paper, parchment paper, or cheesecloth.
Wrapping Parmesan cheese in wax paper, cheese paper, parchment paper, or cheesecloth allows the cheese to breathe and prevents condensation, which can cause spoilage. These materials provide a barrier that protects the cheese from moisture while still allowing some air circulation. This helps to maintain the quality and flavour of the cheese.
Wax paper is a food-safe material that is coated with a thin layer of wax, creating a semi-permeable barrier. It is an ideal wrap for Parmesan cheese as it allows the cheese to breathe while protecting it from excess moisture. Cheese paper, specifically designed for wrapping cheese, is another excellent option. It is usually made of paper coated with a thin layer of plastic, creating a breathable yet protective barrier. Parchment paper, a durable and grease-resistant paper, is also suitable for wrapping Parmesan. It is safe to use in direct contact with food and provides a semi-permeable barrier similar to wax paper. Finally, cheesecloth, a loose-woven cotton cloth, can be used to wrap Parmesan. It allows for airflow and helps maintain the correct amount of moisture around the cheese.
When using these wrapping methods, it is important to ensure that the Parmesan cheese is stored properly. Place the wrapped cheese in an airtight container or a sealed bag and store it in the refrigerator. This will help maintain the optimal temperature and humidity levels for the cheese. Additionally, ensure that the refrigerator is set to the correct temperature, typically between 4°C and 8°C, to create the perfect environment for preserving Parmesan cheese.

Containers: Store in an airtight container or bag
Parmesan cheese is a hard cheese with a lengthy aging process. It is made from skimmed, unpasteurized cow's milk and is typically aged for six months to two years, and occasionally longer than four years. The quality and flavour of Parmesan cheese are best when it's fresh. However, proper storage can prolong its shelf life.
Containers play a crucial role in preserving Parmesan cheese. Exposure to air, moisture, and other foods in the refrigerator can impact the cheese's quality and shelf life. Therefore, it is essential to store Parmesan cheese in an airtight container or bag.
For short periods, Parmesan cheese can be stored at room temperature without suffering any damage. However, once purchased, it is advisable to refrigerate it to maintain its aromatic characteristics and ensure optimal preservation. When storing in the refrigerator, cover the cheese block in plastic wrap or aluminium foil to prevent it from absorbing other smells. Place the wrapped cheese in a crisper drawer. A block of opened Parmesan cheese will last in the fridge for up to two months, while an unopened block can last for nine months.
To further extend the shelf life, you can freeze Parmesan cheese. Freezing can be done in an airtight container or freezer bag. Shredded Parmesan cheese can be stored for three to six months, while a wedge of cheese will stay in the freezer for over a year. When using shredded frozen cheese, break up any clumps before adding it to your dish. To use a frozen wedge, allow it to defrost at room temperature for about ten minutes.
While airtight containers are recommended, some sources suggest leaving the container slightly open or using a box that allows air circulation. This is because condensation can build up in a completely airtight container, leading to spoilage. As a result, some people opt for cheese paper or wax paper, which allows the cheese to breathe while still providing protection.

Refrigeration: Place in the fridge, not the freezer
Parmesan cheese is a hard cheese with a lengthy aging process and a long shelf life. The quality and flavour of Parmesan are best when it's fresh, but refrigeration can help prolong its life.
When storing Parmesan in the fridge, it is important to prevent the cheese from drying out or absorbing other smells. Wrapping the cheese in parchment paper, cheese paper, wax paper, or a wax cloth wrap can help to prevent condensation and allow the cheese to breathe. It is also possible to use plastic wrap or aluminium foil, but these should be combined with another wrapping method to prevent the cheese from drying out. For example, placing the wrapped cheese in a paper towel and then putting it in a plastic bag can help to prevent mould issues. It is important to ensure that the package is sealed and tight, and not exposed to air.
Parmesan cheese can be stored in the refrigerator for several months. An unopened block of Parmesan can be kept for up to nine months, while an opened block will last in the fridge for up to two months. It is recommended to store the cheese in the crisper drawer or on the bottom shelf of the refrigerator.
Freezing Parmesan cheese is not recommended, as it can affect the flavour and texture of the cheese. Some sources suggest that freezing Parmesan is acceptable for grated cheese or for using the cheese in hot dishes, but it should not be thawed and eaten as it is.

Temperature: Keep at 4-8°C
Parmesan cheese is a hard cheese with a lengthy aging process of a minimum of two years and occasionally more than four. The quality and flavour of Parmesan cheese are best when it's fresh, but storing it in the refrigerator or freezer prolongs its shelf life.
Vacuum-packed Parmigiano Reggiano can be stored in the refrigerator at a temperature ranging from 4 to 8°C. It is important to ensure that the package is sealed and tight and not exposed to air. The fatty part of the cheese tends to absorb other smells present in the refrigerator, so it is advisable to keep it in glass or plastic containers.
Another solution is to wrap the Parmesan in food-grade plastic film. This will keep the cheese fresh for a long time, but it is important to periodically check that its conditions have not changed.
It is also possible to store Parmesan cheese in the freezer. This will prolong its shelf life even further. However, freezing the cheese will cause it to dry out, and some flavour and texture will be lost. Frozen Parmesan cheese can be used for baking or melting, but it is best to use fresh cheese whenever possible to enjoy its optimal quality and flavour.

Duration: Lasts 3 weeks to 9 months
Parmesan cheese has a long shelf life, especially when stored properly. An unopened block of Parmesan cheese can last for several months beyond the expiration date when stored correctly. A whole, unopened block of Parmesan cheese can last seven to nine months in the refrigerator, while a whole opened block will last one to two months.
To extend the shelf life of opened Parmesan cheese, keep it in an airtight container or resealable bag in the refrigerator. Make sure the cheese is well-sealed to prevent it from drying out or absorbing odours from the refrigerator. The refrigerator temperature should be below 40°F (4°C).
You can also freeze Parmesan cheese in an airtight container or freezer bag. Frozen shredded Parmesan cheese can last for three to six months, while a wedge of Parmesan cheese will stay in the freezer for over a year. You can use shredded frozen cheese straight from the freezer—just shake it to break up any clumping before use. Place a wedge of frozen Parmesan cheese on a countertop for ten minutes at room temperature to defrost before using.
Note that frozen cheese may become crumbly and lose some of its flavour. Defrosted Parmesan cheese is best suited for cooked dishes, such as sauces, soups, and casseroles.
