Parmesan Reggiano cheese, also known as Parmigiano-Reggiano, is a hard, granular cheese with a rich, nutty flavor. When stored properly, it can last for a long time without going bad. However, it's important to know the signs of spoilage to ensure you're consuming safe and delicious cheese. The most common sign of spoilage in Parmesan Reggiano cheese is the presence of mold. Hard cheeses like Parmesan Reggiano can develop surface mold, which can be cut off without affecting the rest of the cheese. Other signs of spoilage include a change in color, a harder texture, and an off-putting or sour smell. Proper storage is key to extending the shelf life of Parmesan Reggiano cheese, and it should be kept refrigerated at all times, preferably in the crisper drawer.

Parmesan Reggiano cheese can be stored in the refrigerator for up to a year
Parmesan Reggiano cheese is a hard, granular cheese with a rich, nutty flavour. It is a versatile ingredient used in many Italian dishes such as pasta, risotto, and pizza, as well as a garnish for salads, soups, and roasted vegetables.
When it comes to storing Parmesan Reggiano cheese, it is important to follow certain practices to ensure its longevity and maintain its quality. Firstly, Parmesan Reggiano cheese should always be stored in the refrigerator. The ideal place is the crisper drawer, which is usually designated for fruits and vegetables. It is worth noting that hard cheeses like Parmesan Reggiano do not require strict refrigeration, but doing so significantly boosts their shelf life by slowing the growth of bacteria.
To maximise the shelf life of Parmesan Reggiano cheese, it is recommended to wrap the original packaging tightly in plastic wrap or aluminium foil. For optimal results, wrap the cheese first in wax or parchment paper and then cover it with plastic wrap before placing it in the refrigerator. This ensures the cheese remains fresh and preserves its flavour.
By following these storage guidelines, Parmesan Reggiano cheese can be safely stored in the refrigerator for up to a year, even if the "sell-by" or "best-by" date on the package expires. It is important to inspect the cheese periodically for any signs of spoilage, such as mould, colour changes, or unusual smells. If mould is present, it can be safely cut away, and the remaining cheese can still be consumed.
Additionally, it is worth mentioning that Parmesan Reggiano cheese can also be stored in the freezer, which can further extend its shelf life. To freeze, cut the cheese into portions, wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. When properly stored, frozen Parmesan Reggiano cheese will maintain its best quality for about 10 to 12 months but will remain safe to consume beyond that timeframe.

It can also be frozen to extend its shelf life
Parmesan Reggiano cheese is a hard, granular cheese with a rich, nutty flavour. It is highly versatile and is used in a variety of dishes, from pasta to pizza, and even as a garnish.
This cheese has a long shelf life, but it can also be frozen to extend its shelf life even further. Freezing Parmesan Reggiano is a great option if you want to keep it for longer, and it is less prone to "freezer burn" due to its low moisture content. To freeze a chunk or block of Parmesan Reggiano, cut the cheese into portions of no more than half a pound each. Wrap the cheese tightly in heavy-duty aluminium foil or plastic freezer wrap, or place it inside a heavy-duty freezer bag.
When stored properly in the freezer, Parmesan Reggiano will maintain its best quality for about 10 to 12 months but will remain safe to consume beyond that time. It is important to note that freezing will not improve the quality of the cheese, but it will certainly prolong its life.
Before freezing, always check the cheese for any signs of spoilage, such as a change in colour, texture, smell, or taste. Parmesan Reggiano cheese that has gone bad may develop a harder texture and green mould on its surface, along with a mouldy or sour smell. If you notice any of these signs, it is best to discard the cheese.

Mould on the surface can be cut off, but mould in shredded cheese means it must be discarded
Parmesan Reggiano is a hard, granular cheese with a rich, nutty flavour. It is a versatile ingredient used in many Italian dishes such as pasta, risotto, and pizza, as well as a garnish for salads, soups, and roasted vegetables.
Hard cheeses, such as Parmesan Reggiano, are less susceptible to mould than soft cheeses. Mould generally only grows on the surface of hard cheeses and can be safely cut off. To prevent mould, it is important to store Parmesan Reggiano properly. It should be kept in the refrigerator at all times and wrapped tightly in plastic wrap or aluminium foil. For optimal results, wrap the cheese first in wax or parchment paper and then cover it with plastic wrap before refrigerating.
While mould on the surface of Parmesan Reggiano can be cut off, mould in shredded or grated Parmesan Reggiano means the entire package must be discarded. This is because mould spores can penetrate deeper into shredded or grated cheese, increasing the risk of food poisoning if consumed. Therefore, it is important to check shredded or grated Parmesan Reggiano for signs of spoilage, such as a spongy texture and an off-putting smell, and adhere to the "best-before" date.

Spoiled Parmesan Reggiano will have a darker colour, harder texture, and a mouldy or sour smell
Parmesan Reggiano, also known as Parmigiano-Reggiano, is a hard, granular cheese with a pale yellow colour and a rich, nutty flavour. It is highly regarded for its sharp, savoury taste and its high-quality production process, which involves ageing for a minimum of 12 months and up to 36 months.
When it comes to determining if Parmesan Reggiano cheese has gone bad, there are several signs to look out for. Firstly, spoiled Parmesan Reggiano will exhibit a darker colour than its original pale yellow hue. This change in colour is an indication that the cheese is no longer fresh. Additionally, the texture of the cheese will become harder, deviating from its typical granular consistency.
Another tell-tale sign of spoilage is the presence of mould. Parmesan Reggiano, when exposed to air, can develop mould on its surface. This mould can appear as green spots or a soft white mould similar to that found on Brie. While it is generally safe to cut off the mouldy portions and consume the remaining cheese, it is important to be cautious. Ensure that you cut away at least 1 inch around and below the mouldy area, and avoid touching the mould with your knife to prevent cross-contamination.
In addition to visual cues, spoilage can also be detected through smell. Spoiled Parmesan Reggiano may emit a mouldy or sour odour, indicating the presence of unwanted bacteria. If the cheese gives off an ammonia-like smell, it is best to discard it immediately as this could be a sign of advanced spoilage. Trust your senses and, if in doubt, err on the side of caution by disposing of the cheese.
To maximise the shelf life of Parmesan Reggiano, proper storage is essential. It is recommended to keep the cheese refrigerated at all times, wrapping it tightly in plastic wrap or aluminium foil. For optimal results, first wrap the cheese in wax or parchment paper to allow it to breathe, and then cover it with plastic wrap before refrigerating. Properly stored, Parmesan Reggiano can last for up to a year in the refrigerator. Additionally, freezing the cheese is an effective way to extend its shelf life even further.
