What You'll Learn
Store in the fridge
Parmesan cheese is a hard cheese with low moisture content, which means it will last longer than soft cheese. If you want to store your Parmesan in the fridge, follow these steps:
Firstly, it's important to note the difference between Parmesan and Parmigiano Reggiano. Parmigiano Reggiano is a protected cheese with strict aging processes and designated origins. It tends to mould more readily than store-bought grated Parmesan, which often has anti-moulding agents added.
If you have an unopened block of Parmesan, it can be stored in the fridge for seven to nine months. Make sure the package is sealed tightly to prevent exposure to air. If the cheese has been opened, it will last in the fridge for one to two months.
Vacuum-packed Parmesan can last in the fridge for several months, but always check the best-before date on the package for guidance. The more mature the Parmesan, the longer it will keep. Parmigiano Reggiano with a maturation of 12 to 18 months can be kept for about 15 days, whereas a 24-month maturation can be kept for about a month.
If you notice any mould developing on your Parmesan, cut it away, and the rest of the cheese should still be safe to eat. However, if the cheese has turned yellow or has an acrid scent, it has spoiled and should be discarded.

Vacuum-packed
Parmesan cheese is a hard cheese with low moisture content, which means it will last longer than soft cheese. An unopened block of Parmesan cheese can last seven to nine months in the refrigerator, while an opened block will last one to two months. To ensure optimal preservation of the product, it is best to store it in the refrigerator.
If you want to store your Parmesan cheese for several months, vacuum-packing is a great option. Vacuum-packed Parmesan can be stored in the refrigerator at a temperature of 4°C to 8°C. Make sure the package is sealed tightly and not exposed to air. The cheese will then last for several months, depending on its maturation. The more mature or "aged" the Parmesan, the longer it will keep—a 12- to 18-month maturation can be kept for about 15 days, while a 24-month maturation can last for about a month.
It is important to check the "'best by'" date on your package for guidance. If your cheese develops a little mold, don't worry—as long as you cut away the moldy parts, the rest is still edible. However, if the cheese develops an acrid scent, it's best to discard it.
Vacuum-packing is a great way to extend the shelf life of your Parmesan cheese and ensure it stays fresh for longer. Just make sure to follow the temperature and sealing guidelines to get the most out of your cheese!

Waxing
Choosing the Right Wax
Select a type of wax specifically designed for cheese waxing. Different varieties of wax are available, including beeswax, paraffin wax, and cheese wax. These waxes have different melting points and properties, so choose one suitable for your needs.
Melting the Wax
Proper melting of the wax is crucial. Use a double boiler or a dedicated cheese wax melter to melt the wax gently and evenly. Avoid overheating, as it can affect the quality and effectiveness of the wax.
Preparing the Cheese
Start with a clean, dry surface. Cut your Parmesan cheese into desired sizes or blocks. Ensure the cheese is free of moisture, as any moisture trapped inside can lead to mould growth. You can use a cheese cloth to wipe the cheese gently before proceeding.
Applying the Wax
Once the wax is melted, use a natural-bristle brush to apply a thin, even coat of wax to all surfaces of the cheese. Work quickly but thoroughly to avoid missing any spots. Allow the first coat to dry before applying additional layers. Two to three coats of wax are usually sufficient.
Storing Waxed Cheese
Waxed Parmesan cheese can be stored at room temperature in a well-ventilated area. Keep it away from direct sunlight and heat sources. Properly waxed and stored Parmesan cheese can last for several months. However, always inspect the cheese for any signs of mould or discolouration before consumption.

Freezing
Parmesan cheese is a hard cheese with low moisture content, which means it will last longer than soft cheese. However, freezing is an option to prolong its shelf life even further.
When freezing grated Parmesan, it is important to note that the cheese may clump together. To avoid this, you can line a baking sheet with parchment paper, spread the grated cheese evenly, and place it in the freezer until the cheese is frozen. Once frozen, transfer the cheese to a freezer bag or airtight container for longer-term storage.
If you choose to freeze a block of Parmesan, it is crucial to defrost it slowly and correctly. The best way to defrost frozen Parmesan cheese is to transfer it to the refrigerator and allow it to thaw gradually. This slow thawing process helps maintain the cheese's texture and flavour. Avoid defrosting Parmesan cheese at room temperature, as this can impact its quality and safety.
While freezing Parmesan cheese is a viable option, it is worth noting that it may affect the texture and flavour of the cheese. Some people argue that freezing Parmesan changes its texture, making it crumbly or dry. However, if done correctly and consumed within a reasonable time, the impact on flavour and texture should be minimal.

Grated vs block
Grated Parmesan cheese is convenient and can be bought in shelf-stable form, stored in the refrigerator, or even frozen. However, it typically has a shorter shelf life than blocks of Parmesan. A container of grated Parmesan will last about a week in the refrigerator. On the other hand, an unopened block of Parmesan can last seven to nine months in the refrigerator, and an opened block will last one to three months.
Blocks of Parmesan are often considered superior to pre-grated options because they are more cost-effective and versatile. Buying a block of Parmesan allows you to grate or cut off the desired amount, maximising freshness. Additionally, blocks of Parmesan can be stored long-term through methods like waxing or freezing.
Pre-grated Parmesan cheese often contains additives and anti-coagulants, which can impact taste and texture. In contrast, grating Parmesan at home from a block ensures a more authentic flavour and allows you to control the texture and fineness of the cheese.
Some people prefer the convenience of pre-grated Parmesan, especially if they frequently use small amounts in their recipes. Powdered or shelf-stable grated Parmesan can be a good option for those who don't consume Parmesan regularly, as it eliminates the need for grating and has a longer shelf life.
Ultimately, the decision between grated and block Parmesan depends on individual preferences, consumption frequency, and desired convenience. Blocks of Parmesan offer superior taste, versatility, and longevity, but grated Parmesan provides convenience and a longer shelf life, especially in powdered or shelf-stable form.

Yes, you can. Freezing Parmesan cheese is a good option if you have bought a large quantity and want to preserve it for longer. However, it may not taste the same after being frozen.
Parmesan cheese has spoiled when it turns yellow or begins to get mouldy. If your cheese has an acrid scent, toss it out. However, a little mould developing on the cheese is not necessarily a sign that it has gone bad. As long as you cut away any mould, you can continue to eat the cheese.
