Freezing is an effective way to increase the shelf life of raw cheese, but it can also 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 result in a drier, crumblier texture once the cheese is thawed. The type of cheese, the way it is prepared, and how it will be used after thawing all play a role in how well it freezes. In general, semi-firm and firm cheeses with low moisture content, such as cheddar, Colby, and Swiss cheese, freeze well. On the other hand, softer cheeses with higher moisture content are less suited for freezing as they can become damaged and leave a pool of water when thawed. Proper packaging and thawing techniques are crucial to preserving the quality and taste of frozen raw cheese.

Freezing raw cheese can extend its shelf life, but careful preparation is required
Freezing raw cheese is a great way to extend its shelf life, but it requires careful preparation and storage to maintain its quality. The cheese should be wrapped tightly to protect it from the dry environment of the freezer and to prevent the absorption of other odors. It is also important to consider how you plan to use the cheese after freezing, as cheese intended for cooking may fare better than cheese meant for a cheeseboard.
When cheese is frozen, small ice crystals form on the inside, disrupting the internal structure of the cheese. This can affect the texture and quality of the cheese, making it drier, crumblier, and less meltable. Therefore, it is generally recommended to use frozen cheese in cooked dishes such as soups, sauces, or casseroles rather than eating it raw.
The best cheeses for freezing are semi-firm to firm blocks with no rind, such as cheddar, Colby, mozzarella, and provolone. These cheeses have a relatively low moisture content, which means there is less water to form ice crystals and damage the structure of the cheese. Softer cheeses with higher moisture content are not well-suited for freezing and may result in an undesirable pool of cheese when thawed.
To freeze raw cheese, start by wrapping the cheese tightly in parchment paper, followed by a layer of aluminum foil. Then, place the wrapped cheese in an airtight freezer bag or container to protect it from freezer burn and prevent the absorption of odors. Label the bag with the date, and place it in the coldest part of the freezer, away from strong-smelling foods.
When you are ready to use the frozen cheese, proper thawing techniques are essential to preserve its quality and taste. The ideal method is to transfer the cheese from the freezer to the refrigerator and allow it to thaw slowly, which can take up to 24 to 48 hours for a block of cheese. This gradual process helps the cheese retain its texture and moisture content. For those in a hurry, another option is to thaw the cheese in cold water, ensuring the cheese is in a leak-proof package and changing the water every 30 minutes to maintain a safe temperature.

Not all cheese types are suitable for freezing
Freezing cheese can be a great way to extend its shelf life. However, not all cheese types are suitable for freezing. When cheese is frozen, small ice crystals form inside, disrupting its internal structure. This can affect the texture, causing it to become drier, crumbly, and potentially mealy. The degradation of texture is more noticeable in cheeses that are eaten plain rather than melted or cooked into dishes.
Cheeses with a higher water content freeze at higher temperatures and are more susceptible to texture and structural damage. Softer cheeses, such as cottage cheese, are not ideal for freezing due to their higher moisture content, which results in more ice crystals forming and negatively impacting the cheese's structure.
Cheeses with a natural rind, such as Camembert, cloth-bound cheddar, and St. Nectaire, may develop undesirable flavours when frozen. This is because the freezing process can affect the flavour profile of these cheeses.
Semi-firm to firm cheeses with relatively low moisture content, such as cheddar, Colby, provolone, low-moisture mozzarella, and hard Italian styles like Parmesan and Pecorino Romano, tend to freeze well. These cheeses have a lower water content, reducing the risk of damage to their cell walls during freezing.
Additionally, the way you prepare and package the cheese, as well as how you intend to use it after thawing, will impact its suitability for freezing. Proper packaging in airtight containers or vacuum-sealed bags is crucial to prevent freezer burn and odour absorption. Gradual changes in texture and flavour are natural, even under optimal conditions, so finding the right balance between extending shelf life and maintaining quality is essential.

Proper packaging is essential to protect cheese from freezer burn and odours
Proper packaging is key to protecting cheese from freezer burn and odours. Freezer burn occurs when dry air comes into contact with the cheese, so it's important to use airtight packaging. Vacuum-sealed containers are ideal, as they reduce air exposure and can preserve cheese for up to two months. If vacuum sealing is not an option, you can use parchment paper followed by aluminium foil. The parchment paper acts as a barrier, while the foil keeps everything in place. This method can preserve cheese for about a month.
Freezer bags are another option, but they are less effective. If you use a freezer bag, be sure to squeeze out as much air as possible before sealing. It's also a good idea to divide your cheese into smaller portions so you can thaw only what you need. Label the bags with the date, and try to use the cheese within one to two months.
When storing cheese in the freezer, it's important to keep it away from strong-smelling foods, as cheese can absorb odours. Place the cheese in the coldest part of the freezer, away from the door, to maintain a constant temperature. By following these packaging and storage tips, you can help preserve the quality of your cheese.

Freezing raw cheese can change its texture and flavour
Freezing raw cheese is a great way to extend its shelf life. However, it is important to note that freezing can alter the texture and flavour of the cheese.
When cheese is frozen, small ice crystals form on the inside, disrupting the internal structure of the cheese. This can affect the texture, making it drier, crumbly, and mealy. The length of time the cheese is stored can also impact its meltability. Freezing also inactivates microbes in the cheese, such as bacteria, yeasts, and mould, extending its shelf life. However, these microbes are not killed and may become active again when the cheese is thawed.
The type of cheese also plays a role in how well it freezes. Cheeses with higher water content tend to freeze at higher temperatures, resulting in more ice crystals that can damage the structure of the cheese. Softer cheeses with higher moisture content are therefore less suitable for freezing and may result in a pool of cheese upon thawing. In contrast, semi-firm and firm cheeses with lower moisture content, such as cheddar, Colby, and provolone, tend to freeze better.
Proper packaging and thawing techniques are crucial to preserving the quality of the cheese. Airtight packaging or vacuum sealing can help prevent freezer burn and the absorption of odours, while slow thawing in the refrigerator allows the cheese to retain moisture and maintain its texture.
While freezing raw cheese can alter its texture and flavour, it is still a safe and effective method for extending its shelf life. With proper preparation and storage, the impact on texture and flavour can be minimised, and the cheese can still be enjoyed in various dishes.

Raw cheese should be thawed slowly to preserve its texture and moisture content
Freezing raw cheese is a great way to extend its shelf life. However, the texture and quality of the cheese may change, and it may become drier and crumblier. To preserve the texture and moisture content of raw cheese, it is important to thaw it slowly.
When cheese is frozen, small ice crystals form on the inside, disrupting the internal structure of the cheese. As a result, when the cheese is thawed, water is released, causing the cheese to dry out and become crumbly. To prevent this, the cheese should be thawed slowly, allowing the moisture to be reabsorbed into the cheese. The ideal method is to transfer the cheese from the freezer to the refrigerator and let it thaw slowly over a period of 24 to 48 hours. The time required for thawing depends on the size and type of cheese. For example, it is recommended to thaw frozen cheese in the refrigerator for 7 to 8 hours per pound of cheese.
To further preserve the texture and moisture content, it is important to use proper packaging when freezing raw cheese. Airtight packaging or vacuum sealing can reduce air exposure and protect the cheese from freezer burn and the absorption of odours. It is also recommended to wrap the cheese in parchment paper and then in aluminium foil to help keep everything in place while freezing.
While freezing raw cheese can extend its shelf life, it is important to note that the quality and texture may still be impacted. Gradual changes in texture and flavour are natural, even in optimal conditions. Therefore, it is recommended to use frozen raw cheese in cooked dishes such as soups, sauces, or casseroles, rather than eating it raw.
Overall, by slowly thawing raw cheese and using proper packaging techniques, you can help preserve the texture and moisture content of the cheese and extend its shelf life.
