Whether you've shredded the cheese yourself or bought it pre-shredded, it's important to store it properly to make it last longer. Pre-shredded cheese can be kept in the refrigerator for a week or two past its printed date if it's unopened. Once opened, it should be consumed within 3 to 5 days. Homemade shredded cheese lasts for a similar duration of 3 to 5 days, but it's recommended to shred as you go or freeze leftovers for a longer shelf life. Freezing is a good option for both store-bought and homemade shredded cheese if you need to keep it for more than 5 days.

What You'll Learn
Homemade shredded cheese lasts 3-5 days
Homemade shredded cheese will last in the fridge for about 3 to 5 days after shredding, regardless of the type of cheese used. This is because shredding cheese in a home kitchen can contaminate it, reducing its shelf life compared to store-bought shredded cheese.
To maximise the lifespan of homemade shredded cheese, it should be stored in the fridge in a sealed container or bag. If you need to handle the cheese with your hands, make sure you wash them first, and always use a clean spoon to serve it.
If you don't plan to use the shredded cheese within 5 days, it's best to freeze it. Frozen shredded cheese can be stored for up to six months, although soft cheeses like mozzarella may have a worse texture after thawing.
It's important to use your best judgement when consuming shredded cheese. If you notice any strange odours, discolouration, or mould, the cheese has likely spoiled and should be discarded.

Store-bought shredded cheese lasts 3-5 days
Store-bought shredded cheese typically lasts for 3-5 days once opened, although it may be safe to consume for a few days more. The shelf life depends on the type of cheese, with soft cheeses like cheddar and mozzarella lasting for one to two weeks, and hard cheeses like parmesan and Swiss lasting for up to a month.
To ensure the cheese stays fresh for as long as possible, it should be stored in the fridge in a sealed container or bag. It is important to practice good hygiene when handling shredded cheese, such as washing your hands before touching the cheese and using clean utensils to remove the desired amount from the bag or container.
If you need to keep shredded cheese for longer than 5 days, freezing is a good option. Frozen shredded cheese can last for up to six months, although the texture of softer cheeses may be affected.
It is important to note that the quality of shredded cheese begins to deteriorate after opening, and it is recommended to use it within 5 days for optimal freshness. Additionally, always use your best judgment and avoid consuming the cheese if you notice any signs of spoilage, such as off odors, discolouration, or mould.
Compared to store-bought shredded cheese, homemade shredded cheese tends to have a shorter shelf life, lasting for only about 3 to 5 days after shredding, regardless of the cheese type. This is because the shredding process introduces contaminants that shorten the cheese's shelf life. Therefore, it is recommended to shred cheese as needed or freeze leftovers to extend their freshness.

Freezing shredded cheese
Shredded cheese can be frozen, but it's important to follow certain steps to ensure the best results. Firstly, it is recommended to use shredded cheese within 3 to 5 days of shredding or opening pre-shredded cheese. If you wish to freeze it, it's best to do so immediately to maintain quality.
When freezing shredded cheese, it's crucial to use airtight freezer-safe bags or containers. Remove as much air as possible from the bag to minimize freezer burn and preserve freshness and texture. Spreading the shredded cheese on a parchment-lined baking sheet before freezing can help with this, ensuring the shreds are separate before placing them in the freezer.
It is also important to consider the type of cheese. Freezing will alter the moisture content and texture of the cheese, so hard and semi-hard cheeses like cheddar, pepper jack, Swiss, and low-moisture mozzarella are better suited for freezing. Soft cheeses can also be frozen but may be more affected by the change in temperature, resulting in a crumbly or grainy texture.
When it comes to thawing, it's best to transfer the frozen shredded cheese to the refrigerator and allow it to thaw slowly over 24 to 48 hours. This helps preserve the texture. Once thawed, the cheese is best suited for cooked recipes, such as mac and cheese or pizza, rather than being eaten fresh. Frozen shredded cheese should be consumed within two to six months for optimal quality.

Shredded cheese shelf life
The shelf life of shredded cheese depends on several factors, including whether it is store-bought or homemade, the type of cheese, and how it is stored.
Store-bought shredded cheese that remains unopened typically lasts for at least a couple of weeks and often keeps for an additional week or two past the printed date. Once opened, the cheese should be stored in the fridge in a sealed container or bag, and it is recommended to be used within 3 to 5 days. However, some sources suggest that shredded cheese can last for up to a month in the fridge if properly sealed and stored, as long as there are no signs of spoilage, such as sliminess, mould, or off odours.
Homemade shredded cheese has a shorter shelf life compared to store-bought shredded cheese. It typically lasts for about 3 to 5 days after shredding, regardless of the cheese type. If a longer shelf life is desired, it is recommended to shred the cheese as needed or freeze the leftovers.
The type of cheese also affects the shelf life of shredded cheese. Hard cheeses like Parmesan and Swiss have a longer shelf life and can be consumed within a month of purchase, even after opening. On the other hand, soft cheeses like cheddar, mozzarella, and Gouda have a shorter shelf life and should be consumed within one to two weeks of purchase. Freezing shredded cheese can extend its shelf life, with frozen shredded cheese lasting up to six months, although the texture of soft cheeses may suffer.
Overall, while shredded cheese can last beyond 5 days in the fridge, especially if properly stored, it is generally recommended to use it within 3 to 5 days of opening to ensure optimal quality and freshness.

Signs of spoiled shredded cheese
Shredded cheese is a convenient way to add flavour and texture to a variety of dishes. However, it's important to be mindful of its shelf life to avoid consuming spoiled cheese, which can cause gastrointestinal issues and even severe food poisoning.
Appearance
The visual indicators of spoiled shredded cheese can vary depending on the type of cheese. Generally, any significant colour change or discolouration can be a red flag. For example, the exposed part of the cheese may appear whiter due to the loss of beta-carotene. Additionally, look out for browning, which is more common in cheeses like Gouda and Parmesan due to the breakdown of protein.
Some cheeses naturally develop mould, which is desirable and safe to eat. However, unintentional mould growth can indicate spoilage. This mould may appear in different colours, such as blue, red, or white spots, and can produce spores and toxins that make the cheese unsafe. If you notice any unusual colours, textures, or signs of mould, it's best to discard the cheese.
Other appearance indicators include sliminess, oiliness, or bloated packaging. If the cheese has been in the fridge for a while, it may also exhibit changes in texture, such as cracking in hard cheeses like Cheddar due to moisture loss, or a slimy texture in soft white mould cheeses like Camembert caused by bacterial growth.
Smell
As a dairy product, one of the most telling signs of spoiled shredded cheese is an "off" smell. This could resemble spoiled milk, ammonia, or even the scent of your refrigerator or freezer. It's a good idea to smell the cheese when you first buy it to familiarise yourself with its normal aroma, making it easier to detect any deviations.
Taste
Tasting is often a last resort, but it can be the definitive indicator. Take a small piece to taste – if the cheese tastes sour or has an unpleasant aftertaste, it has likely spoiled.
To summarise, shredded cheese should be consumed within 3 to 5 days of opening to avoid spoilage. By being vigilant about the appearance, smell, and taste of your shredded cheese, you can ensure that you're only consuming safe and delicious cheese.
