Shredded Cheese: How Long Does It Last?

How long does an opened bag of shredded cheese last? Well, it depends on a few factors. Firstly, the type of cheese matters – hard cheeses like parmesan and Swiss will last longer (up to a month) than soft cheeses like cheddar and mozzarella (1-2 weeks). Secondly, proper storage is key – transfer the cheese to an airtight container or resealable bag to prevent spoilage from air and moisture. With these considerations in mind, an opened package of shredded cheese should last about 5 to 7 days in the refrigerator. If you're looking to extend the shelf life, you can always freeze your shredded cheese, which will last about 6-8 months in the freezer. However, frozen cheese may lose some of its texture and flavour, so it's best suited for cooked dishes.

Soft shredded cheese like cheddar and mozzarella will last one to two weeks after opening

To maximise the shelf life of your soft shredded cheese, it is important to store it properly. Make sure to seal the original packaging tightly or transfer the cheese to a resealable plastic bag or airtight container. Keep the cheese in the refrigerator at all times and try to store it in the coldest part of the fridge, away from strong-smelling foods.

Even if stored properly, it is important to use your best judgement before consuming soft shredded cheese. If you notice any unusual odours, discolouring, or spots of mould on the cheese, it is best to discard it.

If you want to extend the shelf life of soft shredded cheese, you can freeze it. Freezing can preserve the cheese for up to six months. However, frozen cheese may lose some of its texture and flavour, so it is best suited for cooked dishes like sauces, soups, and casseroles.

Hard shredded cheeses like parmesan and Swiss should be eaten within a month

However, it is important to note that even if no mould is visible, the cheese may still be past its prime. Other signs that hard shredded cheese has gone bad include an unintentional bitter flavour, a fermented fruit taste, and a fizzy sensation on the tongue. If you notice any of these signs, it is best to discard the cheese.

To extend the shelf life of hard shredded cheeses, it is important to store them correctly. This involves removing the cheese from its original plastic packaging and placing it in an airtight container. It should be wrapped loosely in a breathable material, such as wax paper or cheese paper. This will help the cheese to "breathe" and release moisture while protecting it from low humidity in the fridge.

Additionally, it is important to maintain a safe fridge temperature of below 40°F (4°C). Higher temperatures increase the rate at which bacteria multiply, which can cause the cheese to spoil more quickly.

If frozen, shredded cheese should be eaten within six months

Freezing shredded cheese is a great way to preserve it and prevent it from spoiling. When stored in the freezer, shredded cheese should be consumed within six months. This is because freezing affects the texture of the cheese, altering it slightly. Therefore, it is best to use frozen shredded cheese for cooking, as the change in texture becomes unnoticeable once the cheese is melted.

There are a few things to keep in mind when freezing shredded cheese. Firstly, it is recommended to shred the cheese before freezing, as this helps it defrost better. Secondly, use airtight containers or resealable plastic freezer bags to store the cheese and prevent freezer burn and odours. Squeeze out as much air as possible before sealing, as this helps to prevent ice crystals from forming.

When it comes to using frozen shredded cheese, it can be added directly to dishes like casseroles, soups, or pasta without thawing. If you prefer to thaw the cheese before use, it can be defrosted overnight in the refrigerator or left at room temperature for about 20 minutes.

It is important to note that not all cheeses freeze well. Soft cheeses like mozzarella, Gouda, and ricotta may have a poor texture after freezing. Hard cheeses like cheddar, Swiss, and Parmesan freeze better due to their lower moisture content.

Additionally, always use your best judgement before consuming frozen or thawed shredded cheese. If you notice any unpleasant odours, discolouration, or mould, discard the cheese as these are signs of spoilage.

Signs of spoiled cheese include off odours, discolouring, or spots of mould

When it comes to determining if your shredded cheese has spoiled, your senses are your best tools. Signs of spoilage can include off odours, discolouring, or spots of mould.

Off Odours

Cheese is a dairy product, so one of the key indicators of spoilage is an "off" smell, which can be similar to spoiled milk, ammonia, or even a refrigerator or freezer. This distinct odour is caused by the release of free fatty acids and specific volatile compounds during the bacterial or microbial breakdown of the cheese. If your cheese smells unpleasant or rancid, it's best to discard it.

Discolouring

Spoiled cheese may also exhibit changes in colour, with the original yellow or orange hue fading or darkening. In extreme cases, the cheese may even turn black or blue.

Mould

The presence of mould spots, typically white, green, or black, on the surface of the cheese is a clear indication of spoilage. Mould can grow on cheese if it becomes contaminated or if the storage conditions are not optimal.

It's important to note that while small amounts of surface mould on cheese may not be a cause for concern, if the entire piece is covered in thick mould, it may be best to discard it. Additionally, mould is not the only appearance indicator of spoilage. Other signs to look out for include sliminess, oiliness, or bloated packaging.

While shredded cheese can be a convenient option, it's worth mentioning that whole blocks of cheese that you grate yourself tend to have a longer shelf life and melt better due to the absence of anti-clumping additives.

Proper storage can extend the shelf life of shredded cheese

Proper storage is key to extending the shelf life of shredded cheese. When stored correctly, an opened bag of shredded cheese can last for up to two weeks in the refrigerator and up to eight months in the freezer.

To ensure the freshness of your shredded cheese, transfer it to an airtight container or resealable bag. This prevents air and moisture from getting in, which can cause the cheese to spoil. It is best to store the cheese in the coldest part of the fridge, away from strong-smelling foods, to avoid the cheese from absorbing any odours.

If you plan on using the cheese within a couple of weeks, the refrigerator is your best option. However, if you want to stock up on shredded cheese and make it last longer, freezing is the way to go. Place the cheese in a freezer-safe bag or container and pop it into the freezer. When you're ready to use the frozen cheese, simply thaw it in the fridge overnight.

It is important to note that the quality of shredded cheese may decline over time, even with proper storage. The texture may become dry or crumbly, and the flavour may not be as pronounced. However, if you're using the cheese in melted dishes, such as grilled cheese or mac and cheese, you might not notice any difference in texture or taste.

Additionally, always use your best judgement before consuming shredded cheese. If you notice any off odours, discolouring, or spots of mould, it is best to discard the cheese as these are signs of spoilage.
