Cheese Expiration: Freezer Life And Food Safety

Cheese is a versatile and tasty dairy product with a relatively long shelf life. However, it's important to know how long cheese can be safely stored, especially when it comes to consuming cheese past its expiration date. While the shelf life varies depending on the type of cheese, freezing can be an effective way to extend its lifespan. In this article, we will explore how long cheese keeps past its expiration date in the freezer and provide guidelines for different varieties of cheese.

Hard cheese can be kept in the freezer for 6-8 months

Hard cheese will become drier and more crumbly when frozen, and its melting properties may be negatively affected. This is because when cheese is frozen, small ice crystals form on the inside, disrupting its internal structure. When it's thawed, water is released, causing the cheese to dry out.

However, freezing is a good way to preserve hard cheese if you're not planning on eating it for a while, as it will prevent bacteria from growing and causing spoilage. Just be aware that the cheese will have a slightly different taste and texture once it's been frozen.

To freeze hard cheese, portion it into quantities that you're likely to use in one go – for a large block of cheese, don't freeze more than 1 pound (500 grams) per portion. You can also grate or slice the cheese before freezing. Then, wrap the cheese in foil or cheese paper and place it in an airtight ziplock bag or container to prevent freezer burn.

Make sure to freeze the cheese as rapidly as possible to at least -9 °F (-23 °C) to prevent the formation of large ice crystals. Use the quick freeze function on your freezer if it has one.

Soft cheese can be frozen but will lose its texture

Soft cheese can be frozen, but it will lose its texture. Freezing soft cheese is not recommended because it contains a lot of moisture, which will cause it to lose its consistency. Soft cheeses such as mozzarella, cream cheese, brie, feta, gorgonzola, and camembert have higher water content and freeze at higher temperatures than harder cheeses. When frozen, small ice crystals form inside soft cheese, disrupting its internal structure. When thawed, the cheese releases water, causing it to dry out and become crumbly, and potentially mealy.

Freezing soft cheese will also negatively affect its melting properties. For example, mozzarella that has been frozen for four weeks will not melt to the same extent as mozzarella that has been frozen for one week. Freezing soft cheese can also halt the ripening process, as is the case with blue cheese and camembert, where live mould and bacteria populations are essential to give these cheeses their distinctive textures and flavours.

If you do choose to freeze soft cheese, it is best to grate it first and put it in a plastic bag, ensuring that you squeeze out as much air as possible before sealing the bag tightly. Soft cheese should be consumed within one to two weeks of being stored in the fridge.

While freezing soft cheese is possible, it is important to note that it will not retain its original texture and that it is generally recommended to be consumed cooked rather than fresh.

Freezing cheese is best done in a freezer bag

Freezing is a great way to preserve cheese and prevent waste. However, it's important to note that not all cheeses are suited to freezing, and the freezing method can impact the quality of the cheese.

When preparing cheese for freezing, it's best to portion it into quantities that you're likely to use at one time. For large blocks of cheese, such as cheddar, don't freeze more than one pound (500 grams) per portion. Cheese can be frozen in its original packaging or wrapped in foil or cheese paper. If using sliced cheese, separate the slices with parchment paper.

Once packaged, place the cheese in the freezer as rapidly as possible to prevent the formation of large ice crystals, which can affect the texture of the cheese. Aim for a temperature of at least -9 °F (-23 °C).

While cheese can be kept frozen indefinitely, it's best to use it within 6 to 9 months for optimal quality. To thaw frozen cheese, place it in the refrigerator for 7 to 8 hours per pound (500 grams).

It's important to note that freezing cheese can alter its texture and quality. Frozen cheese may become drier, crumbly, and mealy due to the formation of ice crystals during freezing. The higher the fat and water content of the cheese, the more noticeable this effect may be. Therefore, hard and semi-hard cheeses with lower moisture content, such as cheddar, Swiss, and brick cheese, tend to freeze better than softer cheeses.

Cheese can be frozen before or after its best by date

Cheese can be frozen before or after its best-by date. Freezing is a great way to preserve cheese for longer, especially if you're in a pinch. However, it's important to note that freezing will affect the texture and quality of the cheese, making it drier and crumblier. So, if possible, it's best to enjoy cheese fresh to maximize its flavor and texture.

When it comes to the type of cheese, hard and semi-hard cheeses with lower moisture and higher fat content are best suited for freezing. Examples include cheddar, Swiss, brick cheese, and blue cheese. These cheeses can be frozen for up to 6-9 months, although their texture will become crumbly and mealy, and they will be harder to slice.

On the other hand, soft and handcrafted cheeses with high moisture content, such as cream cheese, ricotta, cottage cheese, and quark, are not suitable for freezing. They should be bought in smaller portions and consumed fresh.

Freezing cheese is a convenient way to reduce waste, prolong shelf life, and save money. If you have a large block of cheese that you won't be able to finish before its use-by date, freezing it can be a good alternative. Additionally, freezing allows you to stock up on cheese during sales, even if you won't be able to consume it all at once.

To freeze cheese, portion it into quantities that you're likely to use at once. Wrap the cheese in foil or cheese paper, separate slices with parchment paper, and place it in an airtight container or bag. Freeze the cheese as quickly as possible to prevent the formation of large ice crystals, which can affect the texture and taste.

When it comes to thawing frozen cheese, it's important to do so slowly and safely in the refrigerator. This will help prevent the growth of harmful bacteria. Depending on the quantity, the cheese may take several hours or a couple of days to thaw completely. Once thawed, the cheese should be consumed within a few days to several weeks to allow it to ripen and improve its quality.

Freezing cheese can change its taste and texture

Freezing cheese is a great way to extend its shelf life, but it can also change the taste and texture. While freezing doesn't destroy the nutrients in cheese, it does affect its texture and quality. When cheese is frozen, small ice crystals form on the inside, disrupting the internal structure of the cheese. This can cause the cheese to become drier, crumbly, and mealy when thawed, as the ice crystals release water and affect the cheese's ability to melt.

The changes in texture and meltability are more noticeable in softer cheeses with higher moisture content, such as mozzarella, cream cheese, and Brie. These cheeses can become very watery when thawed and may not be suitable for eating plain. Harder cheeses, such as cheddar, Swiss, and brick cheese, can also become crumbly and difficult to slice, but they will still melt reasonably well.

Additionally, freezing can affect the ripening process of cheeses with live mold and bacteria populations, such as blue cheese and Camembert. Freezing damages these microbes, potentially decreasing the overall sensory quality of the cheese.

Overall, freezing cheese is best suited for cooked dishes where changes in texture are less noticeable, such as sauces, pizzas, or grilled cheese sandwiches. To minimize the impact on taste and texture, it is recommended to use frozen cheese as a secondary ingredient rather than the main focus of a dish.
