The Longevity Of Jarlsberg Cheese: How Long Does It Last?

Jarlsberg cheese is a semi-hard, medium-fat cheese with holes, first developed in 1956 by Professor Ole Martin Ystgaard and his team at the Agricultural University of Norway in Ås. It is a unique cheese with a distinctive sweet and nutty flavour, a smooth texture, and large holes. But how long does it last? The shelf life of Jarlsberg cheese depends on several factors, including the form of the cheese, storage conditions, and whether it has been frozen.

Opened Jarlsberg cheese will last 3-4 weeks in the fridge

The longevity of Jarlsberg cheese depends on several factors, including the form of the cheese, the storage conditions, and whether it has been opened.

Jarlsberg cheese is a semi-hard to semi-soft cheese, which means it has a shorter fridge life than harder, aged cheeses. It is important to use your judgment and senses to determine if the cheese is still good after the expiration date. The cheese may develop mold, but this can be safely cut away if it is not completely covered. However, if there is red or black mold, the cheese should be discarded.

If you want to extend the shelf life of Jarlsberg cheese even further, you can freeze it. Cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them in a heavy-duty freezer bag. Frozen in this way, Jarlsberg cheese will maintain its best quality for about six months but will remain safe to consume beyond that time.

Unopened, it can be kept in the deli packaging

When storing unopened Jarlsberg cheese, it is important to keep it in its original deli packaging and to refrigerate it at all times. This will ensure the cheese stays fresh for as long as possible.

Jarlsberg cheese is a semi-soft cheese, which means it has a shorter shelf life than harder, aged cheeses. Harder cheeses have less internal moisture, so they are less affected by the passage of time. However, if stored correctly, an unopened package of Jarlsberg cheese will last for 6-8 months in the refrigerator.

To maximise the shelf life of unopened Jarlsberg cheese, it is recommended to wrap the original packaging tightly in plastic wrap or aluminium foil. For even better results, wrap the cheese first in wax or parchment paper and then cover it with plastic wrap before refrigerating. This will help to regulate the amount of moisture in the cheese, as it needs to breathe.

To further extend the shelf life of unopened Jarlsberg cheese, it can be frozen. When freezing, it is important to place the cheese in the freezer before the number of days shown for refrigerator storage has elapsed. Properly stored, it will maintain its best quality for about 8 months, but it will remain safe to eat beyond that time.

It can be frozen to extend its shelf life

Jarlsberg cheese is a semi-hard to semi-soft cheese with a distinctive sweet and nutty flavour and a smooth texture. It is a living biological product, so its flavour, aroma and texture may vary from batch to batch. When stored in the refrigerator, an opened chunk of Jarlsberg cheese will typically last for 3 to 4 weeks. However, to extend its shelf life, it can be frozen.

Freezing is a great way to always have some cheese on hand. When freezing a chunk or block of Jarlsberg cheese, cut the cheese into portions no larger 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. Properly stored, it will maintain its best quality for about 6 months in the freezer, but it will remain safe to consume beyond that time.

Frozen cheese may become crumbly and lose some of its flavour, so it is best suited for cooked dishes such as sauces, soups and casseroles. To thaw the cheese, it is recommended to defrost it in the refrigerator, which can be done for an additional 3 to 4 days before using. If the cheese is thawed in the microwave or in cold water, it should be used immediately.

It is important to note that while freezing can extend the shelf life of Jarlsberg cheese, it may alter its texture and taste. For optimal flavour and freshness, it is recommended to consume the cheese within the original refrigeration timeframe if possible.

It can be defrosted and kept for an additional 3-4 days in the fridge

If you've frozen your Jarlsberg cheese, it can be defrosted and kept for an additional 3 to 4 days in the fridge. This is the best option if you want to keep your cheese for longer, as freezing it will help to extend its shelf life. However, it's important to note that frozen cheese may become crumbly and lose some of its flavour, so it's best suited for cooked dishes such as sauces, soups, and casseroles.

To freeze a chunk or block of Jarlsberg cheese, 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. Alternatively, you can place the portions inside a heavy-duty freezer bag. When stored properly, Jarlsberg cheese will maintain its best quality for about 6 months in the freezer, but it will remain safe to eat beyond this time.

If you're planning to defrost your Jarlsberg cheese, it's best to do so in the fridge. This will give you an additional 3 to 4 days to use the cheese before it needs to be discarded. If you defrost the cheese in the microwave or in cold water, it should be consumed immediately.

Remember, the key to maximising the shelf life of Jarlsberg cheese is proper storage. When refrigerating, keep the cheese wrapped in its original packaging or tightly covered in plastic wrap or aluminium foil. For even better results, wrap the cheese first in wax or parchment paper before covering it with plastic wrap.

It is safe to eat Jarlsberg cheese left unrefrigerated for 3 hours

It is generally recommended that Jarlsberg cheese be kept in the refrigerator at all times. However, in certain situations, it may be safe to consume Jarlsberg cheese that has been left unrefrigerated for a short period.

In one instance, a user on Reddit posted about accidentally leaving a block of Jarlsberg cheese unrefrigerated for about three hours, with the air conditioner set at 79 degrees Fahrenheit. They were concerned about whether it was still safe to refrigerate and consume the cheese later. Other users responded that the cheese should be safe to consume as long as it doesn't have any mould on it. It is important to note that temperature-controlled food should not be kept in the "danger zone" of 40°F to 140°F for more than two hours if storing or four hours if consuming and then discarding.

According to experts, the shelf life of Jarlsberg cheese depends on its storage conditions and the type of cheese. Unopened sliced Jarlsberg deli cheese can be kept in its original packaging in the refrigerator for 3 to 4 weeks after purchase. Once opened, it should be wrapped tightly in plastic wrap or aluminium foil and can last for a similar duration. For longer-term storage, Jarlsberg cheese can be frozen, maintaining its best quality for about 8 months but remaining safe to consume beyond that period.

Jarlsberg cheese is a semi-hard to semi-soft cheese, which typically has a fridge life of about two to four weeks after the expiration date. However, it is important to use your judgment and senses to determine if the cheese has gone bad. If there is any mould, it is recommended to cut off at least 1 inch around and below the mouldy area and ensure that the knife does not touch the mould.

In conclusion, while it is generally recommended to keep Jarlsberg cheese refrigerated, it may be safe to consume the cheese if left unrefrigerated for three hours, as long as it shows no signs of spoilage, such as mould or an off odour, flavour, or appearance. However, it is important to exercise caution and use your judgment to ensure the cheese is safe to consume.
