Fresh-Cut Cheese: How Long Does It Stay Good?

Cheese is a delicious and versatile food, but it doesn't last forever. The shelf life of cheese depends on its moisture content, and the type of cheese you have will determine how long it keeps for. Soft cheeses like feta, mozzarella, and cream cheese are more perishable and should be consumed within one to two weeks of opening. Harder cheeses, like cheddar or parmesan, can last for up to four weeks in the fridge. To make the most of your cheese, it's important to know how to store it properly and recognise the signs of spoilage.

Soft cheeses like mozzarella, feta, and brie should be consumed within 1-2 weeks

Soft cheeses tend to spoil more quickly than hard varieties. This is because they contain more moisture, making them more susceptible to bacterial growth. Therefore, soft cheeses like mozzarella, feta, and brie should be consumed within 1-2 weeks of being cut.

If you're looking to extend the shelf life of these cheeses, there are a few things you can do. Firstly, ensure that the cheese is always refrigerated. Additionally, wrap the cheese tightly in plastic wrap or aluminium foil, or, for an even better seal, wrap the cheese first in wax or parchment paper and then cover it with plastic wrap before refrigerating.

If you're looking for an even longer-term storage solution, you can try freezing your soft cheeses. To do this, 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, or place them inside a heavy-duty freezer bag. 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.

How can you tell if your soft cheese has gone bad? Fresh mozzarella that is going bad will typically develop an off smell, and if mould appears, discard it entirely. Feta cheese will last about 5-7 days if sealed tightly and refrigerated, but if submerged in brine, it can last about a month. Feta cheese that has gone bad will develop mould, discolouration, a strong off smell, or texture changes such as becoming slimy or crumbly. Brie cheese that is spoiling will develop a hard texture around the edges, darken in colour, and develop an off smell. If mould that was not part of the manufacturing process appears on the brie, discard it entirely.

Hard cheeses like cheddar and gouda can be stored in the fridge for about 6 weeks

Hard cheeses, such as Cheddar, Parmesan, and Gouda, have a longer shelf life than soft cheeses because they contain less moisture, which makes them less prone to spoilage from bacteria. Generally, unopened hard cheeses don't need to be refrigerated, but they will last much longer if they are. Unopened blocks of hard cheese can last up to 6 months in the fridge.

Once opened, hard cheeses like Cheddar, Gouda, and Parmesan can be safely stored in the fridge for about 6 weeks. They should be stored in an airtight container or wrapped tightly and kept in the coldest part of the fridge. It's important to note that the shelf life of hard cheeses in the fridge also depends on factors such as the quality of the cheese, the storage method, and the temperature of the fridge. To maintain the moisture of the cheese, it should be wrapped in wax, parchment, or cheese paper.

It's always a good idea to inspect hard cheeses for mold before consuming them. If you notice any mold, simply cut off at least 1 inch (2.5 cm) around and below the affected areas. White specks or crystallized patches on certain aged hard cheeses like Cheddar, Parmesan, and Gouda are normal and safe to eat. These spots are most likely calcium lactate crystals, which form when the lactic acid in the cheese combines with calcium.

To extend the shelf life of hard cheeses, you can also freeze them. Hard cheeses can be frozen for up to 8 months if the packet is intact. However, freezing may affect the texture and taste of the cheese to some extent.

Semi-hard cheeses like Gruyère and Gouda can be kept for 2-3 weeks

Semi-hard cheeses, such as Gruyère and Gouda, can be kept for 2-3 weeks in the refrigerator. To ensure your semi-hard cheese lasts for the full two to three weeks, follow these steps for proper storage:

• Remove the cheese from its plastic packaging.
• Wrap it loosely in a pliable yet breathable material, such as wax paper or cheese paper.
• Put the cheese in a container with an airtight lid.

The shelf life of semi-hard cheeses is longer than that of soft cheeses because they contain less moisture. This lower moisture content makes it more difficult for bacteria to grow, thus prolonging the life of the cheese.

When it comes to specific types of semi-hard cheeses, there are slight variations in their shelf lives. For example, an opened package of Gouda will last for 2 to 3 weeks in the refrigerator, while an opened chunk of Gruyère will last for 1 to 2 weeks when wrapped correctly and stored in the refrigerator, or 3 to 4 weeks if properly wrapped and stored.

To maximize the shelf life of semi-hard cheeses, it is important to pay attention to refrigeration and packaging. For optimal storage conditions, the temperature should be kept between 34°F and 38°F (1°C and 3°C) with a relative humidity of around 85% to prevent the cheese from drying out or becoming too moist, which can encourage mold growth.

Freezing cheese: while not recommended, it can be done for a few months

Freezing cheese is not recommended, as it can negatively affect the texture and quality. However, if you wish to prolong the shelf life of your cheese, freezing can be an option for a few months.

Cheese has a relatively long shelf life, and proper storage can further extend its freshness. Soft cheeses, such as ricotta, feta, and mozzarella, typically last about a week in the fridge, while hard cheeses like aged cheddar can be enjoyed for up to four weeks after opening.

If you intend to freeze cheese, it's important to note that its texture and quality will be impacted. The formation of ice crystals during freezing disrupts the internal structure of the cheese, leading to a drier and crumblier texture upon thawing. Additionally, the freezing process can affect the melting properties of some cheeses.

When deciding which cheese to freeze, consider the following:

• Hard and semi-hard cheeses like cheddar, Swiss, and blue cheese can be frozen but may become crumbly and difficult to slice.
• Soft cheeses with high water and fat content, such as Camembert, Brie, and cottage cheese, can be frozen but will suffer more in terms of texture.
• Cream cheese can be frozen but may separate upon thawing, requiring whipping to restore its texture.
• Processed cheese slices, such as American cheese, and soft cheeses like ricotta, cottage cheese, and cream cheese, do not freeze well.

For the best results, freeze cheese in its original unopened packaging or in a resealable plastic bag with as much air removed as possible. Alternatively, wrap the cheese tightly in parchment paper and then in aluminium foil to protect it from freezer burn.

While cheese can be kept frozen indefinitely, it is recommended to use it within two to three months for the best quality. Harder cheeses like Parmesan may last a bit longer.

When thawing frozen cheese, place it in the refrigerator for a couple of hours or overnight. It is important not to refreeze cheese that has already been frozen and thawed, as this will further affect its texture and flavour.

How to tell if cheese has gone bad: look for mold, dryness, or a strange smell

Freshly cut cheese can be safely stored in the fridge for a few days to several weeks, depending on the type of cheese. Soft cheeses like ricotta, feta, and mozzarella will typically last for about a week, while hard cheeses like aged cheddar or Parmigiano Reggiano can last for up to four weeks. However, it's important to know how to identify spoiled cheese. Here are some signs to look for:

Appearance

Cheese, especially harder varieties, is prone to developing surface mould. Small amounts of mould on hard cheese can be trimmed off, and the rest of the cheese can be consumed. However, if the entire piece is covered in thick mould, it's best to discard it. Mould isn't the only indicator of spoilage. Changes in colour, texture, or signs of sliminess, oil, or bloated packaging can also indicate that the cheese has gone bad.

Smell

Smell is another important indicator of cheese spoilage. A spoiled cheese may emit an "`off`" odour, reminiscent of spoiled milk, ammonia, or even a refrigerator or freezer. Some cheeses naturally have a pungent aroma, so it's a good idea to smell the cheese when you first purchase it to establish a baseline. If the cheese develops a sour milk smell or an ammonia-like odour, it's best to discard it.

Taste

Tasting is a last resort but can be a definitive way to tell if your cheese has gone bad. If you suspect spoilage, only taste a small piece. If the cheese tastes sour or has an unpleasant aftertaste, it has likely spoiled.

In summary, spoiled cheese may exhibit signs of mould, changes in colour or texture, or emit an unpleasant odour. If you're unsure, tasting a small piece can confirm whether the cheese has gone bad. Remember to consume cheese by the date on the label or within a few days of purchasing it to ensure freshness and quality.
