Cheese is a beloved food item for many, but it is also a delicate product that requires careful storage to ensure it stays fresh. Cheese wheels, in particular, pose a challenge for those looking to make a bulk purchase, as once the wheel is cut, the cheese will only last a few weeks in the refrigerator before going bad. However, there are ways to extend the shelf life of cheese wheels, such as re-waxing or vacuum-sealing, and certain types of cheese, such as hard cheeses, naturally have a longer lifespan. This article will explore the best practices for storing cheese wheels and provide insights into how long different types of cheese can last.
| Characteristics | Values |

What You'll Learn
Soft cheeses go bad faster
Soft cheeses typically have a higher moisture content, which makes them more susceptible to bacterial growth and spoilage. Fresh soft cheeses, like cottage cheese, are particularly vulnerable as they are essentially blank canvases for any type of bacteria to grow on. Harder cheeses, on the other hand, have a lower moisture content, which makes them less prone to bacterial growth and, therefore, last longer.
Soft cheeses, such as Brie and chèvre, are very moist. While this moisture is essential for the growth of good cultures and moulds that give these cheeses their flavour and health benefits, it also creates an ideal environment for harmful bacteria to thrive. For this reason, soft cheeses are more perishable and have a shorter shelf life than harder cheeses.
The U.S. Department of Health advises against leaving perishable foods, including soft cheeses, unrefrigerated for more than two hours. Examples of soft cheeses include cottage cheese, cream cheese, brie, fresh mozzarella, burrata, feta, and ricotta. These cheeses have a higher risk of spoilage if left unrefrigerated for extended periods, and it is recommended to discard them if they have been left out for longer than two hours.
Semi-soft cheeses, such as manchego, Gouda, and provolone, have a slightly longer ripening period of 30-90 days. They tend to have a higher moisture content and a wider range of flavour profiles. While they are easier to slice and have a creamy texture, they still fall into the category of cheeses that are more perishable and should be consumed or properly stored promptly to prevent spoilage.
In general, soft cheeses will typically last about a week in the refrigerator once opened, whereas hard cheeses can last up to a month. It is important to note that the shelf life of cheese can vary depending on factors such as the type of cheese, storage conditions, and individual cheese characteristics.

Hard cheeses last longer
Hard cheeses, such as aged cheddar, aged gouda, and Parmigiano Reggiano, last longer than soft cheeses because they have a low moisture content, making it difficult for bacteria to flourish. According to cheese experts, hard cheeses can last about four weeks in the refrigerator once opened, while unopened packages can last about six months.
To store hard cheese in the refrigerator, remove it from its plastic packaging and wrap it loosely in cheese paper or wax paper. Put the cheese in an airtight container and store it in a cool, dry place. The ideal temperature for storing cheese is between 50°F and 70°F, with an optimal range of 45°F to 58°F.
Hard cheeses can also be stored at room temperature, especially if they are aged. However, it is important to note that the refrigerator is still a great place to store cheese, as it helps to inhibit mold growth and maintain the cheese's flavor and texture.
When storing hard cheese, it is important to allow the cheese to breathe and release moisture while protecting it from low humidity in the fridge. One way to do this is to turn the cheese over periodically to prevent moisture from settling on one side. Additionally, when wrapping hard cheese, it is recommended to change the wrap every 2-3 days to prevent bacteria growth.

Refrigeration and freezing
Refrigeration
When storing cheese wheels in a refrigerator, it is important to maintain a temperature below 40°F (4°C). This temperature range helps to inhibit the growth of mould and bacteria, keeping the cheese safe for consumption. It is recommended to wrap cheese wheels in porous materials, such as cheese paper or wax paper, to prevent them from drying out. This allows the cheese to breathe while maintaining optimal moisture levels.
Hard cheeses, such as alpine cheeses, generally have a longer shelf life than soft cheeses. They can be stored in the refrigerator for 3–4 weeks, while soft cheeses typically last for at least 7 days. It is important to inspect hard cheeses for mould and remove any affected areas before consumption. On the other hand, soft cheeses with mould, such as cottage cheese or cream cheese, should be discarded entirely.
Freezing
Freezing is an option for extending the shelf life of cheese wheels. Most types of cheese, except soft cheeses like ricotta, cottage cheese, and cream cheese, can be frozen. Frozen cheese can be stored safely for up to 6 months at a temperature of 0°F (-18°C) or below. When thawing frozen cheese, it is recommended to do so in the refrigerator to maintain food safety.
Freezing may cause changes in the texture of certain cheeses, such as cheddar, making them crumbly. However, these cheeses can still be used in soups or sauces where they will be thoroughly melted. Freezing is a useful method to preserve cheese wheels for extended periods, but it is important to consider the potential textural changes that may occur during the thawing process.

Proper storage
Firstly, it is important to note that the refrigerator is an ideal place to store cheese wheels, especially after they have been opened, as it inhibits mould growth. An opened wheel of cheese can last three to four weeks in the refrigerator, and up to six months in the freezer. However, when freezing cheese, it is recommended to thaw it in the fridge rather than on the counter to avoid altering the texture.
The optimal temperature range for storing cheese is between 45°F and 58°F (approximately 7°C to 14°C). This temperature range helps to balance moisture and humidity, which are crucial factors in cheese preservation. Maintaining a consistent temperature is crucial, as fluctuations can impact the cheese's quality.
For soft cheeses like ricotta, feta, and mozzarella, proper storage is critical due to their high moisture content, which makes them more perishable. Soft cheeses should be consumed within a week of opening, and their wrapping should be changed every two to three days to prevent bacteria growth. Soft-ripened cheeses like Brie have delicate rinds, so they should be wrapped in cheese paper or parchment paper and stored in an airtight container.
Hard cheeses, such as aged cheddar, gouda, and Parmigiano Reggiano, have a lower moisture content, making it challenging for bacteria to flourish. As a result, hard cheeses can last about four weeks in the refrigerator once opened and up to six months if unopened. To store hard cheeses, remove them from their plastic packaging and loosely wrap them in cheese paper, wax paper, or foil for certain varieties like blue cheese. Then, place the cheese in an airtight container.
Additionally, it is worth noting that cheese wheels should be turned over periodically during storage to prevent moisture from settling on one side. This practice helps to distribute moisture evenly and maintain the cheese's quality.
Finally, when unwrapping a new cheese wheel, it is advisable to use the same paper to rewrap it, adding plastic wrap or a Ziploc bag as an extra layer of protection. By following these storage guidelines, you can extend the lifespan of your cheese wheels and enjoy their delicious flavours for longer.

Re-waxing and re-sealing
If you've cut into your cheese wheel, it will only last a few weeks in the refrigerator before it goes bad. However, there is a solution to extend its life: re-waxing and re-sealing.
When re-waxing, it is important to use the appropriate type of wax. Cheese wax, a type of food-grade wax, is specifically designed for coating cheeses. It is important to ensure that the wax you use is food-safe and free of harmful chemicals.
In addition to re-waxing, proper storage is crucial to maximize the shelf life of your cheese wheel. The ideal storage temperature for cheese is between 50°F and 70°F, with 45°F to 58°F being optimal for refrigerators. Keep the cheese in a cool, dry place, as humidity can negatively impact its quality. Turn the cheese wheel periodically to prevent moisture from settling on one side.
By combining re-waxing with proper storage practices, you can significantly extend the life of your cheese wheel, delaying the onset of spoilage and maintaining its flavour and texture. Remember to inspect your cheese regularly for any signs of mould or deterioration, and always follow food safety guidelines when consuming cheese beyond its recommended shelf life.
