Unopened Monterey Jack Cheese: How Long Does It Last?

Monterey Jack cheese is a versatile and tasty dairy product with a relatively long shelf life. The length of time it lasts depends on various factors, such as whether it is opened or unopened, and the format in which it is purchased. For instance, unopened shredded Monterey Jack cheese will last for about a week after the Sell By or Best By date on the package, whereas an unopened block of the same cheese will last for about 6 months in the refrigerator.

Unopened Monterey Jack cheese will last for about 6 months in the fridge

Unopened Monterey Jack cheese will last for about six months in the fridge. This is true for both blocks of cheese and shredded or sliced cheese. However, it's important to note that the cheese should be kept refrigerated at all times and in its original packaging to maximize its shelf life.

The exact answer to how long unopened Monterey Jack cheese lasts depends on storage conditions. To ensure the cheese stays fresh for as long as possible, it should be stored in the refrigerator and not opened until ready to use. If stored properly, unopened Monterey Jack cheese will typically remain safe to consume for about six months, even if the "sell-by" or "best by" date on the package expires.

To further extend the shelf life of unopened Monterey Jack cheese, it can be frozen. When freezing, it is recommended 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. Frozen in this way, Monterey Jack cheese will maintain its best quality for about six to eight months but will remain safe to consume beyond that time.

It's important to note that the shelf life of Monterey Jack cheese may vary depending on factors such as the quality of the cheese, storage temperature, and humidity levels. Therefore, it is always a good idea to inspect the cheese for any signs of spoilage, such as mould, a hard texture, discolouration, or a strong smell, before consuming it.

To maximise shelf life, don't open the package until ready to use

To maximise the shelf life of unopened Monterey Jack cheese, do not open the package until you are ready to use its contents. This is because, once opened, the cheese will only last for 3 to 4 weeks in the refrigerator.

Unopened, the cheese will remain safe to use for about 6 months, even if the "sell-by" or "best by" date on the package expires. This applies to both wrapped blocks of cheese and sliced cheese from the deli counter.

To further extend the shelf life of unopened Monterey Jack cheese, you can freeze it. When freezing, place the cheese in the freezer before the number of days shown for refrigerator storage has elapsed. To freeze a chunk or block of cheese, cut the cheese into portions no larger than half a pound each, and wrap tightly in heavy-duty aluminum foil or plastic freezer wrap, or place inside a heavy-duty freezer bag.

Properly stored, Monterey Jack cheese will maintain its best quality for about 6 to 8 months in the freezer, but it will remain safe to eat beyond that time. Frozen cheese may become crumbly and lose some of its flavour, so it is best suited to cooked dishes such as sauces, soups, and casseroles.

Unopened shredded Monterey Jack cheese will last for about 1 week after the Sell By date

To maximise the shelf life of shredded Monterey Jack cheese, do not open the package until you are ready to use it. It is important to keep shredded Monterey Jack cheese refrigerated at all times. The best way to maximise the shelf life of shredded cheese is to store it in the freezer. When freezing, place the cheese in the freezer before the number of days shown for refrigerator storage has elapsed. To freeze shredded cheese, tightly seal the original packaging and place it in the freezer. If you are freezing for longer than 2 months, place the package inside a heavy-duty freezer bag to prevent freezer burn.

Properly stored, shredded Monterey Jack cheese will maintain its best quality for about 8 months, but it will remain safe to eat beyond that time. Frozen cheese may lose some of its texture and flavour, so it is best suited to cooked dishes, such as sauces, soups, and casseroles.

To determine whether shredded Monterey Jack cheese is safe to eat, use your senses. If the cheese develops an off odour, flavour, or appearance, it should be discarded. If mould appears, discard all of the shredded cheese.

To extend shelf life, freeze the cheese

To extend the shelf life of unopened Monterey Jack cheese, you can freeze it. When freezing, place the cheese in the freezer before the number of days shown for refrigerator storage has elapsed.

To freeze unopened Monterey Jack cheese, cut the cheese into portions no larger than 1/2 pound each. You can then wrap the cheese tightly in heavy-duty aluminum foil or plastic freezer wrap, or place it inside a heavy-duty freezer bag.

How you store your cheese in the freezer will impact how well it maintains its texture and flavour. To prevent freezer burn, squeeze out as much air as possible and ensure the cheese is tightly sealed. You can also wrap the cheese in parchment paper and then in aluminum foil. The parchment paper will create a good barrier for the cheese, while the foil will help keep everything in place.

Properly stored, frozen Monterey Jack cheese will maintain its best quality for about 6 to 8 months, but it will remain safe to eat beyond that time. Frozen cheese may become crumbly and lose some of its flavour, so it is best suited to cooked dishes such as sauces, soups, and casseroles.

If mould appears in a package of shredded cheese, discard the entire package

Unopened Monterey Jack cheese will typically last for about six months in the refrigerator. However, it is crucial to maintain proper storage conditions by keeping the cheese refrigerated at all times. To maximise shelf life, the cheese should remain unopened and in its original packaging until ready to use.

If mould appears in a package of shredded Monterey Jack cheese, it is imperative to discard the entire package. Unlike harder cheese blocks, shredded cheese has a higher surface area exposed, providing an ideal environment for mould to spread quickly. The porous nature of soft cheeses allows mould to proliferate beneath the surface, even if it appears contained to a small area. Therefore, it is unsafe to consume shredded cheese with visible mould, and the entire package should be thrown away.

To extend the shelf life of shredded Monterey Jack cheese, freezing is an option. However, it is crucial to seal the original packaging tightly and place it in the freezer before the recommended refrigerator storage time has elapsed. Frozen shredded cheese may lose some texture and flavour, making it more suitable for cooked dishes like sauces, soups, and casseroles.

When dealing with mould on cheese, it is essential to exercise caution. While some harder cheeses can be salvaged by cutting away the mouldy portion, this does not apply to shredded cheese. The presence of mould indicates the growth of microscopic roots called hyphae, which spread throughout the food, making it unsafe for consumption.

To prevent mould from appearing prematurely, it is advisable to follow proper food handling practices. Ensure hands are washed before handling cheese, avoid touching the cheese directly, and store it in an airtight container. Additionally, maintain a clean refrigerator, monitor the temperature, and keep cheese away from high-moisture items.
