The Lifespan Of Grated Cheese: How Long Does It Last?

Grated cheese is a convenient way to add flavour to a variety of dishes, but how long does it last in the fridge? The shelf life of grated cheese depends on the type of cheese and how it is stored. Hard cheeses like Parmesan and Swiss should be consumed within a month of purchase, while soft cheeses like cheddar and mozzarella have a shorter shelf life of one to two weeks. Freezing grated cheese can extend its shelf life by up to six months. However, it is important to use your best judgement and discard the cheese if you notice any unpleasant odours, discolouration, or mould.

How long does grated soft cheese last?

Soft cheese lasts for a shorter period than hard cheese. This is because soft cheeses have a higher moisture content, which provides an environment for bacteria to thrive. Therefore, soft cheese is more perishable than hard cheese.

Once opened, soft cheese like cheddar and mozzarella will only be good for one to two weeks. If you notice any off odours, discolouring, or spots of mould on your soft cheese, don't eat it! These signs mean the cheese has likely spoiled.

To ensure your soft cheese lasts as long as possible, proper storage is key. For cheese sold in brine, like feta or fresh mozzarella, keep it in the liquid and make sure the container's lid is secure. For blue cheese, you can wrap them in foil. Soft-ripened cheese, like Brie, has a delicate rind, so it needs more care than other soft cheeses. Wrapping it in cheese paper is best, but you can also use parchment paper and keep it in an airtight container.

How long does grated hard cheese last?

Grated hard cheese typically lasts for about a month in the refrigerator. Hard cheeses like Parmesan and Swiss should be eaten within a month of purchase. Unopened hard cheeses can last for several months and even up to a year when stored in the fridge. Once hard cheese is opened, it can last for a few weeks to a couple of months.

It is important to note that the shelf life of grated hard cheese may vary depending on factors such as the storage method, temperature, and humidity of the refrigerator. Additionally, the presence of additives or preservatives in the cheese may also impact its shelf life.

To extend the shelf life of grated hard cheese, it is recommended to store it in an airtight container or wrap it tightly in the coldest part of the refrigerator. This will help to protect the cheese from moisture and humidity fluctuations, which can promote bacterial growth and mould formation.

It is also important to regularly inspect grated hard cheese for any signs of spoilage, such as mould, discolouration, or an unpleasant odour. If mould is present, it is necessary to discard the cheese, as consuming mouldy cheese can pose health risks.

In summary, grated hard cheese can last for about a month in the refrigerator, but proper storage and regular inspections for spoilage are crucial to ensure its safety and maximise its shelf life.

How to store grated cheese

Grated cheese is a convenient way to add flavour to a variety of dishes, but how do you store it to ensure its freshness and longevity? Here are some detailed tips on how to store grated cheese:

Choose the Right Container

Select an appropriate container to store your grated cheese. Opt for an airtight container with a secure lid to prevent excess air from reaching the cheese, which can cause it to dry out or spoil. Make sure the container is clean and dry before adding the grated cheese.

Use the Right Storage Material

Line your container with paper towels or a thin cloth before adding the grated cheese. This will help absorb any excess moisture, which can cause the cheese to become soggy or mouldy. You can also place the grated cheese in a resealable plastic bag and squeeze out as much air as possible before sealing it tightly.

Store in the Correct Location

Place the container of grated cheese in the coldest part of your refrigerator. The temperature of your fridge should be maintained at below 40°F (4°C) to ensure the cheese stays fresh. Avoid storing grated cheese on refrigerator shelves that are prone to temperature fluctuations, such as the door shelves. Instead, opt for the middle or bottom shelves, which tend to be colder and more stable.

Monitor the Quality Regularly

Regularly inspect your grated cheese for any signs of spoilage. Look for mould, discolouration, or changes in texture. If you notice any visible signs of spoilage, discard the cheese immediately. Additionally, if the cheese develops an unusual or unpleasant odour, it is best to throw it out.

Use Within the Recommended Timeframe

Even when stored properly, grated cheese has a limited shelf life. Aim to use the cheese within one to two weeks for softer varieties like cheddar and mozzarella, and within a month for harder cheeses like parmesan and Swiss cheese. Remember that these are general guidelines, and it is always best to use your judgement and err on the side of caution when it comes to food safety.

Handle with Care

When handling grated cheese, use clean utensils and avoid contamination with other foods, especially raw meat, poultry, or fish. Wash your hands thoroughly before handling the cheese to prevent the transfer of bacteria.

By following these simple steps, you can maximise the freshness and longevity of your grated cheese, ensuring it remains a tasty and safe addition to your favourite recipes.

Can you freeze grated cheese?

Yes, you can freeze grated cheese. Freezing cheese is a good way to reduce waste and save money. However, it's important to note that not all cheeses can be frozen.

Hard and semi-hard cheeses such as cheddar, Swiss, gouda, emmental, mozzarella, and parmesan are suitable for freezing. However, softer cheeses like brie, camembert, cottage cheese, and ricotta are not as they have a higher water content, which means they are more susceptible to damage caused by ice crystals forming in the freezing process.

When freezing grated cheese, it's best to use freezer-proof bags. Squeeze out any excess air in the bag before sealing, then place the bag in a second bag and seal again. Label the bag with the date of freezing and try to lay it completely flat in the freezer to stop the grated cheese from clumping together. Grated cheese can be kept in the freezer for up to three months.

When you're ready to use the frozen grated cheese, place the desired amount on a plate and defrost it in the fridge for one to two hours. This will work well for sandwiches, or you can use the cheese straight from frozen by sprinkling it on top of a pizza or adding it to a dish that will be cooked.

How to tell if grated cheese has gone bad

Grated cheese is a convenient way to add flavour and texture to a variety of dishes, but it's important to ensure that it is still safe to consume. Here are some detailed signs to look out for to determine if your grated cheese has gone bad:

Check the Expiry Date

Although the "best before" or "sell by" dates on cheese are primarily a guide for optimal quality rather than safety, they can still be a useful indicator. Cheese can often be safely consumed beyond these dates if stored correctly. Hard cheeses, for instance, can last for several months, or even up to a year, when unopened and stored in the fridge.

Visible Mould

The presence of visible mould on grated cheese is a clear indication that it has spoiled and should be discarded. Blue cheese is an exception, as the blue mould in these varieties is intentional and safe for consumption. For other types of cheese, cut off at least 1 inch (2.5 cm) around and below the mouldy spots.

Odour

Cheese typically has a characteristic smell that varies according to its type. However, if the cheese gives off a sour, rancid, or ammonia-like odour, it is likely a sign of spoilage. Trust your senses, and if it smells off, it's best to discard it.

Texture

Spoiled cheese may exhibit noticeable changes in texture. It may become overly dry, crumbly, or slimy to the touch. These textural changes are an indication that the cheese has gone bad and should not be consumed.

Discolouration

Significant alterations in colour, such as yellowing or browning, can be a tell-tale sign of spoilage. Grated cheese should generally maintain its original colour, and any noticeable discolouration could indicate that it has gone bad.

Taste

If you are still unsure, you can carefully taste a small amount of the cheese. If it has an off or sour flavour, it has likely spoiled and should be discarded. However, always exercise caution, as consuming spoiled food can potentially lead to food poisoning or other health issues.

In summary, grated cheese can last for a limited period, and it's crucial to inspect it for any signs of spoilage before consumption. When in doubt, it's better to be safe and discard the cheese rather than risk potential health hazards.
