Gruyere cheese is a hard cheese that is typically aged for a period of two to 36 months, and sometimes even longer. The aging process gives hard cheeses a distinct, crumbly texture and more complex flavours. When it comes to unopened Gruyere cheese, its longevity depends on how it is stored. If stored in the refrigerator, an unopened package of shredded Gruyere cheese will generally last for about a week after the Sell By or Best By date. If stored in the freezer, an unopened package of shredded Gruyere cheese will last indefinitely.

Unopened shredded Gruyere cheese will last for about a week after the Sell By date
Gruyere is a hard cheese, typically considered to be vegetarian-friendly and gluten-free. It is made from cow's milk and contains significantly less lactose than other dairy products. Hard cheeses like Gruyere are aged for longer periods, anywhere from one to six months, and have a distinct, crumbly texture. They are made by removing most of the whey from the curds during the cheesemaking process, which leads to a lot of the moisture being removed.
Unopened shredded Gruyere cheese will last for about a week after the "Sell By" or "Best By" date on the package, if stored properly in the refrigerator. To maximize the shelf life of shredded Gruyere cheese, do not open the package until you are ready to use it. Bacteria grow rapidly at temperatures between 40 °F and 140 °F; shredded Gruyere cheese should be discarded if left out for more than 2 hours at room temperature.
You can further extend the shelf life of unopened shredded Gruyere cheese by freezing it. When freezing, place the shredded cheese in the freezer before the number of days shown for refrigerator storage has elapsed. Frozen shredded Gruyere cheese will keep safe indefinitely if kept constantly at 0 °F.
It is important to note that frozen cheese may become crumbly and lose some of its flavor. Thawed cheese will be best suited for cooked dishes such as sauces, soups, and casseroles. To check if your shredded Gruyere cheese has gone bad, look for signs such as a hard texture, dark colour, strong smell, or the presence of mold. If any of these are present, discard the cheese.

Bacteria grows rapidly at temperatures between 40 °F and 140 °F, so shredded Gruyere should be discarded if left out for more than 2 hours
Gruyere is a type of cheese that falls between the hard and soft categories. Unopened hard cheeses don't need to be refrigerated but will last much longer if they are. Unopened blocks of hard cheese can last up to 6 months in the fridge. Generally, hard cheeses will last 3-4 weeks in the refrigerator once opened.
Shredded Gruyere cheese should be stored in the refrigerator at all times. An unopened package of shredded Gruyere will last about 1 week after the "Sell By" or "Best By" date on the package. If you want to extend the shelf life of unopened shredded Gruyere cheese, you can freeze it.
Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the "Danger Zone". Never leave food out of refrigeration for more than 2 hours. If the temperature is above 90 °F, food should not be left out for more than 1 hour.
Therefore, shredded Gruyere cheese should be discarded if left out for more than 2 hours at room temperature. If shredded Gruyere cheese is left out for too long, it may develop an off odor, flavor, or appearance, and should be discarded.

Gruyere cheese that has been constantly frozen at 0°F will remain safe indefinitely
Gruyere cheese is categorized as a semi-soft to semi-hard cheese. Therefore, it can be kept in a refrigerator for two to three weeks after being opened. If unopened, it can last for up to six months in the fridge.
To further extend the shelf life of Gruyere cheese, it can be frozen. When freezing, it is best to cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty aluminum foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag.
It is important to note that the freezer time indicated is for the best quality of cheese. To determine if the cheese has gone bad, one can look at its odor, flavor, appearance, and texture. Gruyere cheese that is going bad will typically develop a very hard texture, darken in color, develop a strong smell, and mold may appear.

Gruyere cheese that is going bad will develop a hard texture, darken in colour, smell strongly and mould may appear
Unopened blocks of hard cheese like Gruyere can last up to 6 months in the fridge. Gruyere is a semi-hard Swiss cheese that is sweet but slightly salty, with a flavour that varies with age. When young, it is often described as creamy and nutty, becoming more assertive, earthy, and complex as it matures. When fully aged, it tends to have small cracks that impart a slightly grainy texture.
However, if stored for too long, even if unopened, Gruyere cheese can go bad. One of the signs of Gruyere cheese going bad is the development of a hard texture. This can be caused by the cheese drying out due to being stored in low humidity conditions. Gruyere cheese that is going bad may also exhibit a noticeable darkening in colour, usually accompanied by a strong smell. The cheese may take on an ammonia-like odour, resembling cat pee or unwashed taint, which can be quite off-putting.
In addition to the changes in texture and colour, mould may begin to appear on the surface of the cheese. While some types of mould, such as white fluffy yeast, are used intentionally during the cheesemaking process, other moulds can indicate that the cheese has spoiled. Blue mould, for example, is considered undesirable and should be removed manually if present.
To prolong the shelf life of unopened Gruyere cheese, it is recommended to store it in the fridge, where it can last for several months. Additionally, ensuring that the cheese is stored at the optimal humidity level of between 94% and 98% can help prevent it from drying out or becoming smeary and gluey.

To extend the shelf life of Gruyere cheese, wrap it tightly in heavy-duty aluminium foil or plastic freezer wrap
Gruyere cheese is a semi-soft cheese with a shorter shelf life than harder cheeses. To extend the shelf life of Gruyere cheese, wrap it tightly in heavy-duty aluminium foil or plastic freezer wrap. This creates the necessary humidity to extend the cheese's shelf life. However, it is worth noting that aluminium foil and plastic wrap are not ideal for long-term cheese storage. This is because they do not allow the cheese to breathe, which can lead to trapped moisture and gases, creating unpleasant flavours and aromas and potentially fostering bacterial growth.
For optimal results, first wrap the cheese in wax or parchment paper, and then cover it with plastic wrap before refrigerating. If you wish to store the cheese for even longer, freezing is a good option. Cut the cheese into portions no larger than half a pound each, then wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. When stored in the freezer, Gruyere cheese will maintain its best quality for about six months but will remain safe to consume beyond that time.
It is important to note that the cheese should be frozen before the number of days shown for refrigerator storage has elapsed. After defrosting, the cheese will be best suited to cooked dishes as it may become crumbly and lose some of its flavour. Additionally, frozen cheese should be consumed within three to four days of being thawed in the refrigerator. If the cheese is thawed in the microwave or cold water, it should be consumed immediately.
