Parmesan cheese is a staple in many kitchens, known for its distinct flavour and hard texture. While it has a longer shelf life than softer cheeses, Parmesan cheese does indeed go bad. The ageing process contributes to its durability, but even so, it has a finite shelf life. Proper storage is key to prolonging its freshness, and there are several signs of spoilage to watch out for, such as mould, changes in smell, and taste.

How to spot if Colanna Parmesan cheese has gone bad
Parmesan cheese has a long shelf life due to its low moisture content and hard texture. However, it can still go bad. To spot if Colanna Parmesan cheese has gone bad, there are several things to look out for.
Firstly, always inspect the cheese for any signs of spoilage. This includes visible mould, which is a sure sign of deterioration. If mould is present, the affected parts should be removed immediately, and good hygiene practices should be maintained to minimise the transfer of bacteria.
Another indicator of spoilage is an "off" smell. If the cheese has developed an unusual or unpleasant odour, it has likely gone bad. Changes in taste can also signify spoilage.
For pre-grated Colanna Parmesan cheese, pay attention to the "best by" date on the packaging. While this date is not a hard-and-fast expiration, it provides a guideline for the cheese's freshness. Proper storage, such as keeping the cheese in an airtight container or wrapping it in wax paper and aluminium foil, can extend its shelf life beyond this date.
Finally, consider the texture of the cheese. If the Colanna Parmesan has developed extensive mould growth or if the texture has significantly changed, it is best to discard it.
By being vigilant and inspecting the cheese for any of these signs of spoilage, you can ensure food safety and maintain the quality and freshness of your Colanna Parmesan cheese.

How to store Colanna Parmesan cheese
Parmesan cheese is a delicate product that requires careful storage to maintain its quality and flavour. Colanna Parmesan cheese, in particular, should be stored properly to ensure its freshness and prevent spoilage. Here are some detailed instructions on how to store Colanna Parmesan cheese:
Refrigerate After Purchase:
Colonna Brothers recommend refrigerating their grated Parmesan cheese after purchasing it. This is due to the temperature variance the product may experience before it reaches the consumer. By refrigerating the cheese, you can maintain a consistent temperature that is optimal for preservation.
Optimal Temperature Range:
Store Colanna Parmesan cheese in the refrigerator at a temperature ranging from 4°C to 8°C (39°F to 46°F). This temperature range will help preserve the organoleptic features of the cheese, ensuring it remains in its optimal condition.
Storage Duration:
Vacuum-packed Colanna Parmesan cheese can be stored in the refrigerator for several months. This packaging method helps extend the shelf life of the cheese by creating an airtight environment that slows down the deterioration process.
Separate from Other Foods:
When storing Colanna Parmesan cheese in the refrigerator, keep it away from other foods with strong odours. The fatty part of the cheese can absorb other smells, which may negatively impact the flavour of the Parmesan.
Avoid Freezing:
It is generally not advisable to freeze Parmesan cheese. Freezing can affect the texture and flavour of the cheese, potentially causing it to become crumbly and dry. Instead, focus on maintaining a consistent temperature within the recommended range in your refrigerator.
By following these storage instructions, you can ensure that your Colanna Parmesan cheese remains fresh and flavourful, allowing you to enjoy its high quality and delicious taste for a longer period.
