Freezing cheese is a topic of debate among cheese enthusiasts. While it is possible to freeze cheese, the act of freezing can affect its flavour and texture, resulting in crumbly, dry cheese. Freezing cheese is generally not recommended for artisanal cheese or cheese to be served with wine, as it can alter the taste and make it unpleasant. However, freezing can be useful for bulk cheese or cheese intended for cooking, especially harder cheeses with low moisture content, as it can prolong their shelf life. Proper wrapping and storage are essential to prevent freezer burn and maintain cheese quality.

What You'll Learn
Freezing cheese changes its texture and flavour
Freezing cheese can alter its texture and flavour, and experts generally advise against it. However, it is possible to freeze cheese if you plan to cook with it.
When cheese is frozen, the water molecules present in it undergo a phase transition from liquid to solid, forming ice crystals. These ice crystals grow and spread within the cheese as it freezes. The formation of ice crystals impacts the cheese's structure and texture. As water freezes, it expands, creating pressure on the surrounding protein and fat structures. This pressure can rupture the cheese's protein network, leading to a breakdown of its texture, especially in softer varieties. This results in a crumbly, dry, and mealy texture upon thawing.
The texture change can vary depending on the type of cheese. Hard cheeses with low moisture content, such as Parmigiano Reggiano, freeze relatively well and can be frozen for up to six months to a year without significant quality loss. On the other hand, soft cheeses with high moisture content, such as cream cheese, are more susceptible to texture changes and should be consumed within two weeks if refrigerated. Freezing soft cheese may result in a chunkier texture.
Additionally, freezing cheese can affect its flavour. Freezer burn, which occurs when frozen food comes into contact with frigid air, can cause dehydration and oxidation of the cheese's surface, negatively impacting its flavour and overall quality. Exposure to air can also lead to oxidation, causing changes in colour and flavour.
To minimise texture and flavour changes when freezing cheese, it is recommended to set your freezer to a sufficiently low temperature, ideally -18°C (0°F) or lower. At this temperature, the freezing process occurs rapidly, minimising the formation of large ice crystals and helping to preserve the cheese's texture and flavour. Proper wrapping and storage are also crucial to preventing freezer burn and maintaining quality.

Freezing cheese is safer than storing at higher temperatures
Freezing cheese is a better option than storing it at higher temperatures, as it inhibits the growth of harmful microorganisms. While freezing cheese can negatively impact its texture and flavour, it is still a safer option for long-term storage.
Cheese is a dairy product that can spoil quickly if not stored properly. While refrigeration is typically recommended for short-term storage, freezing can be a viable option for extending the shelf life of cheese. Freezing temperatures of -18°C (0°F) or lower help prevent the growth of bacteria and other microorganisms that can cause foodborne illnesses.
When cheese is frozen, the water molecules in it undergo a phase transition from liquid to solid, forming ice crystals. These ice crystals can rupture the internal structure of the cheese, leading to a crumbly texture upon thawing. However, this change in texture does not necessarily indicate that the cheese has gone bad or is unsafe to eat.
Additionally, freezing cheese can affect its flavour, as the formation of ice crystals can alter the cheese's molecular structure. This can result in a duller or less enjoyable taste. However, proper handling and thawing techniques can minimise these negative effects.
Some types of cheese, such as hard cheeses with low moisture content, freeze relatively well and can be stored in the freezer for up to six months to a year. On the other hand, soft cheeses with high moisture content, such as cream cheese, are less suitable for freezing as they are more likely to suffer from textural changes.
In conclusion, while freezing cheese may not be ideal for optimal taste and texture, it is a safer option than storing cheese at higher temperatures over extended periods. Proper wrapping, rapid freezing, and thawing in the refrigerator can help mitigate some of the negative effects of freezing on cheese quality.

Hard cheeses freeze better than soft cheeses
Freezing cheese is generally not recommended, as it can negatively impact its flavour and texture. However, if you need to freeze cheese, hard cheeses are a better option than soft cheeses.
Hard cheeses, such as Parmigiano Reggiano, age well in the refrigerator and can last for extended periods without going bad. They also tend to have low moisture content, which makes them less susceptible to the formation of large ice crystals during freezing. As a result, their texture and flavour are less likely to be compromised. To freeze hard cheese, it is recommended to cut it into chunks, wrap it in parchment paper and foil, and then place it in an airtight plastic bag.
On the other hand, soft cheeses with high moisture content, such as ricotta, chevre, and fresh mozzarella, are more prone to freezer damage. Freezing and thawing soft cheeses can cause their molecular structure to break down, resulting in a mealy, crumbly, and dry texture. They are also more susceptible to freezer burn, which can further affect their taste and texture.
While hard cheeses can withstand freezing relatively well, it is still important to note that freezing any type of cheese will result in some changes to its texture and flavour. Therefore, it is generally recommended to only freeze cheese that you intend to use for cooking, as frozen cheese may not be suitable for serving as a table cheese. Additionally, it is crucial to wrap the cheese tightly and minimise air exposure to prevent freezer burn and maintain quality.

Freezing cheese for more than 6 months is not recommended
Freezing cheese is a great way to reduce waste and prolong shelf life, especially if you have a large block of cheese that you won't be able to consume before its use-by date. However, freezing cheese for more than six months is not recommended.
While cheese can be stored in the freezer indefinitely without posing any health risks, the quality of the cheese will deteriorate over time. The longer cheese is stored in the freezer, the more its taste and texture will be affected. This is because freezing causes ice crystals to develop in the cheese, disrupting its structure and making it drier, crumbly, and mealy. Freezing also inactivates the microbes in cheese, such as bacteria, yeasts, and mold, which can prevent it from ripening properly and decrease its overall sensory quality upon thawing.
Therefore, it is best to limit freezing cheese to a maximum of six months. To ensure optimal taste and texture, it is recommended to properly thaw the cheese slowly in the refrigerator, which can take up to a day or two, depending on the quantity. Additionally, frozen cheese is best suited for cooking rather than eating fresh, as the freezing process can alter its texture and consistency.
To freeze cheese for up to six months, it is important to follow proper storage procedures. Portion the cheese into small amounts, wrap it tightly, and place it in an airtight container or bag to prevent dry air from causing freezer burn. Freeze the cheese as rapidly as possible to prevent the formation of large ice crystals, and maintain a temperature of 0 degrees Fahrenheit or below.

Freezing cheese is best reserved for cooking
Freezing cheese is not recommended by experts, as it tends to compromise the texture and flavour. However, if you need to freeze cheese, it is best reserved for cooking.
Freezing cheese can alter its texture, making it crumbly and dry. This is because, on a molecular level, when cheese is frozen, the water molecules present in the cheese turn into solid ice crystals. These ice crystals grow and spread within the cheese, impacting its structure and texture. When the cheese is thawed, the ice crystals melt, but the internal structure of the cheese has already changed, resulting in a softer texture.
Some cheeses are more susceptible to freezer damage than others. Cheeses with fissures, holes, or cracks are more vulnerable to the formation of ice crystals. Soft cheeses with high moisture content are also more likely to be affected by freezing, as the ice crystals can rupture the protein network, leading to a crumbly texture. Hard cheeses with low moisture content, on the other hand, freeze relatively well and can be frozen for up to six months to a year.
Freezing cheese is generally done for cooking purposes, as the altered texture and flavour may not be suitable for table cheese. Frozen cheese can be used in dishes like nachos or sandwiches, where the cheese is melted or paired with other ingredients. Freezing cheese can also be useful for extending the shelf life of cheeses that deteriorate quickly in the fridge, such as Parmesan and Gruyere.
To effectively freeze cheese and minimise texture and flavour changes, it is recommended to set your freezer to -18°C (0°F) or lower. Additionally, wrapping the cheese tightly in plastic wrap or aluminium foil before placing it in an airtight container can help prevent freezer burn and maintain quality.
