Gruyere cheese is a semi-hard Swiss cheese with a rich, nutty, and slightly sweet flavor. It is a versatile ingredient known for its exceptional melting properties and is often used in fondue, gratins, and sandwiches. Like most cheeses, Gruyere can go bad if not stored properly. So, does it go bad after the expiration date? Well, it depends on a few factors. Firstly, whether the cheese is opened or unopened before the expiration date. An unopened package of shredded Gruyere cheese will typically last for about a week after the expiration date if stored properly. On the other hand, an opened chunk of Gruyere will usually stay safe to consume for 3 to 4 weeks after the expiration date if it is wrapped correctly and stored in the refrigerator.
| Characteristics | Values |
|---|---|
| Expiry Date | Gruyere cheese will remain safe to use for 3 to 4 weeks after the "sell-by" or "best-by" date on the package |
| Opened Package | Once opened, it should be consumed within 1 to 2 weeks when wrapped correctly and stored in the refrigerator |
| Unopened Package | An unopened package of shredded Gruyere cheese will last for about 1 week after the "sell-by" or "best-by" date |

How to store Gruyere cheese
Gruyere cheese is a hard cheese that generally scores 9 out of 10 on the hardness scale. It is a sturdy and durable cheese that can be stored in a variety of ways to extend its shelf life.
Refrigerating Gruyere Cheese
When storing a chunk of Gruyere cheese in the refrigerator, it is important to wrap it tightly to prevent air and moisture from affecting the cheese. Firstly, wrap the cheese in wax, parchment, or baking paper. Then, cover it with plastic wrap or aluminium foil before placing it in the refrigerator. This method will keep the cheese fresh for about 3 to 4 weeks.
Freezing Gruyere Cheese
To store Gruyere cheese for an extended period, freezing is recommended. Cut the cheese into portions of no more than half a pound each. Then, wrap the portions tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. Frozen Gruyere cheese will maintain its best quality for about 6 months, but it can be safely stored indefinitely at 0°F.
Thawing Frozen Gruyere Cheese
When thawing frozen Gruyere cheese, it is best to defrost it slowly in the refrigerator. A chunk of cheese defrosted in the refrigerator can be kept for an additional 3 to 4 days before use. If the cheese is thawed in the microwave or cold water, it should be used immediately as its texture and flavour may change. Thawed cheese is best suited for cooked dishes like sauces, soups, and casseroles.
Signs of Spoilage in Gruyere Cheese
Even when stored properly, Gruyere cheese can spoil over time. Signs of spoilage include a very hard texture, discolouration, a strong smell, and the presence of mould. If mould is present, cut away at least one inch around and below the mouldy area without touching the mould with the knife. Then, re-cover the cheese with fresh wrap. If the cheese shows signs of pinkish or reddish discolouration, or smells like ammonia, it should be discarded.

Signs of spoilage
Gruyere cheese is a semi-hard Swiss cheese with a nutty and slightly sweet flavour. It is a versatile ingredient with excellent melting properties, making it ideal for gratins, fondue, sauces, and sandwiches.
Like most cheeses, Gruyere can go bad if not stored properly. To extend its shelf life, it is recommended to keep it refrigerated at a constant temperature of around 35°F (1-4°C), wrapped tightly in plastic wrap or aluminium foil. When wrapped and stored correctly, an opened chunk of Gruyere will typically last for 1 to 4 weeks.
- Texture Changes: Gruyere cheese that has gone bad may exhibit unusual texture changes, such as excessive hardness, dryness, sliminess, grittiness, or excessive moisture. Frozen cheese may also become crumbly.
- Taste Alteration: A bitter, overly sour, or strange taste is a clear indication that Gruyere cheese has spoiled and is no longer safe to consume.
- Unpleasant Odour: An off smell, such as a sour, musty, or otherwise unpleasant odour, is a sign of spoilage. Some have described it as smelling like ammonia.
- Visible Mold: While some cheese molds are harmless, it is generally recommended to discard the cheese if mold is present, as it could indicate the presence of harmful bacteria. If the cheese is cut into chunks or blocks, it may be safe to cut away at least 1 inch (2.5 cm) around and below the moldy area, being careful not to touch the mold with the knife. However, if the cheese is shredded, sliced, or crumbled, the entire package should be discarded.
It is important to note that proper storage and handling are crucial to maintaining the quality and safety of Gruyere cheese. This includes rewrapping the cheese tightly after each use, using clean utensils to avoid cross-contamination, and storing it in a cool, dark place like a cheese drawer in the fridge, avoiding temperature fluctuations.

How to freeze Gruyere cheese
Gruyere cheese can be frozen to extend its shelf life. It is best to cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty plastic wrap or aluminium foil. Then, place the wrapped cheese in a freezer bag, pushing out as much air as possible before sealing. It is important to note that frozen cheese may become crumbly and lose some of its flavour and texture, so it is best suited for cooked dishes such as sauces, soups, and casseroles.
To ensure the best flavour, it is recommended to keep the freezer just below freezing. Frozen gruyere will retain most of its flavour for up to three months, and while it remains safe to eat indefinitely if kept frozen, the flavour may deteriorate over time.
For shredded Gruyere cheese, tightly seal the original packaging and place it in the freezer. If freezing for longer than two months, it is advisable to use a heavy-duty freezer bag to prevent freezer burn.
Another option is to grate the cheese and toss it with cornstarch before freezing. This allows you to take only the amount you need from the freezer, reducing waste.

How long does opened Gruyere cheese last?
Gruyere cheese is a semi-hard Swiss cheese with a nutty and slightly sweet flavor. It is known for its exceptional melting properties and versatility in various dishes, from fondue and gratins to sandwiches and sauces.
To ensure food safety and maintain the quality of opened Gruyere cheese, proper storage is essential. After each use, the cheese should be rewrapped tightly to limit exposure to air and potential contaminants. It is best stored in an airtight container in the refrigerator at a consistent temperature between 34°F (1°C) and 39°F (4°C). Avoid the refrigerator door or top shelf, as temperature fluctuations can affect the cheese's quality. Additionally, use clean utensils to prevent bacteria introduction and cross-contamination.
When properly stored, an opened chunk of Gruyere cheese will typically last for 1 to 2 weeks, maintaining its flavor and texture. However, if the cheese is not wrapped correctly or is exposed to temperature fluctuations, its shelf life may be shorter.
To further extend the shelf life of opened Gruyere cheese, it can be frozen. When freezing, cut the cheese into portions no larger than 1/2 pound each, and wrap tightly in heavy-duty aluminum foil, plastic freezer wrap, or a heavy-duty freezer bag. Frozen cheese may become crumbly and lose some of its flavor, so it is best suited for cooked dishes such as sauces, soups, and casseroles.
It is important to regularly check for signs of spoilage, even within the expected shelf life. Key indicators that Gruyere cheese has gone bad include an unpleasant odor, the presence of mold, unusual hardness, dryness, or excessive moisture, and a bitter or overly sour flavor. If any of these signs are present, discard the cheese to prevent food poisoning.

How to handle mouldy cheese
Gruyere cheese that has been opened can be safely consumed for 3 to 4 weeks after the "sell-by" or "best by" date on the package. If mould appears on a chunk or block of Gruyere cheese, cut off at least 1 inch around and below the mouldy area, ensuring that you do not touch the mould with the knife. Then, re-cover the cheese in fresh wrap. However, if mould appears in a package of shredded, sliced, or crumbled Gruyere cheese, discard the entire package.
Now, for some general guidelines on handling mouldy cheese:
Firstly, it is important to assess the type of cheese. Fresh soft cheeses, such as ricotta, mascarpone, and chèvre, should be discarded because the mould has likely penetrated deep into the cheese, negatively impacting its flavour.
For soft cheeses like Brie or Port Salut, cut off about a quarter to half an inch away from any surface where mould is visible. The thick white rind on Brie, for instance, is a type of mould that is safe to consume and even adds to the flavour.
Hard, aged cheeses like aged Cheddar or Parmesan are less susceptible to mould. Simply scrape off the mould, and the cheese will be safe to eat.
In general, moulds that are white, fuzzy, and tinged with green are relatively safe to cut away. However, black or grey moulds are less desirable, and you should remove a more generous portion of the cheese to ensure that any potentially affected areas are discarded.
If the mouldy cheese smells of ammonia or is both mouldy and wet, discard it entirely. To prevent mould from forming, store cheese in your crisper drawer or a dedicated wine fridge, which provides a less cold environment that is better for the cheese.
