Types of Vacuum Sealed Cheese
When discussing the longevity of vacuum sealed cheese, it’s crucial to consider the type of cheese. The texture, moisture content, and fat content will all impact how long the cheese can last when vacuum sealed.
Hard Cheeses
Examples include Parmigiano-Reggiano, Cheddar, and Gouda. Hard cheeses generally have lower moisture levels compared to softer varieties, making them last longer. Vacuum sealed hard cheeses can typically be stored for:
- Unopened: 6 to 12 months
- Opened: 3 to 6 months
Soft Cheeses
Soft cheeses like Brie, Camembert, and cream cheese have higher moisture content, leading to shorter shelf lives. When vacuum sealed, they can last:
- Unopened: 1 to 2 months
- Opened: 1 to 2 weeks
Blue Cheeses
Characters like Roquefort and Gorgonzola are known for their mold. Vacuum sealing can extend their life, but the complexity of their makeup means they still won’t last as long as hard cheeses. Expect:
- Unopened: 3 to 4 months
- Opened: 2 to 3 weeks

How long does vacuum sealed cheese last in the refrigerator?
Vacuum sealed cheese can last significantly longer in the refrigerator compared to non-sealed cheese. Generally, vacuum sealed cheese can maintain its best quality for about 4 to 8 months when stored in the fridge. This extended shelf life is due to the reduced exposure to air, which delays spoilage and helps retain flavor and texture.
However, it’s important to keep in mind that the quality may gradually decline over time. For optimal flavor and texture, it’s recommended to consume vacuum sealed cheese within the first few months. Always check for any signs of spoilage before using it, such as unusual odors, discolorations, or mold that isn’t typical for the cheese variety.
Can vacuum sealed cheese go bad?
Yes, vacuum sealed cheese can go bad, although it may take longer than cheese stored in traditional packaging. While vacuum sealing helps preserve the cheese’s freshness by limiting exposure to air and moisture, it does not make the cheese immune to spoilage. Factors such as temperature fluctuations or improper sealing can affect the shelf life and quality of the cheese.
<pIf you believe your vacuum sealed cheese is spoiled, inspect it closely. Look for signs such as an off smell, discoloration, or the development of molds that are not intended for that specific cheese type. If you notice any of these signs, it’s safer to discard the cheese to avoid any potential health risks.
How should I store vacuum sealed cheese?
To maximize the shelf life of vacuum sealed cheese, it should be stored in the refrigerator at a consistent temperature of 34-40°F (1-4°C). It’s best to keep it in the original vacuum-sealed packaging until you’re ready to use it. Once opened, wrap the cheese in parchment paper or wax paper before placing it in an airtight container to maintain its freshness.
Additionally, avoid storing the vacuum sealed cheese near strong-smelling foods, as it can absorb odors. Regularly check the cheese for any signs of spoilage and remember to keep your refrigerator clean and at the proper temperature to ensure optimal storage conditions.
Does vacuum sealing change the texture of cheese?
Vacuum sealing cheese can have an impact on texture, particularly over extended periods. For cheeses with higher moisture content, such as Brie or Camembert, vacuum sealing can sometimes lead to a change in the creamy texture, making it slightly firmer or grainy when opened. However, this varies greatly depending on the type of cheese and how it is sealed and stored.
Cheeses with lower moisture content, like Parmesan or aged Cheddar, tend to maintain their texture well when vacuum sealed. In general, proper sealing and storage will help preserve the cheese’s original characteristics, but always remember that some changes might occur over time. Enjoying the cheese while it’s still fresh will minimize any textural changes.
Is it safe to eat vacuum sealed cheese past its expiration date?
While vacuum sealed cheese can sometimes be safe to consume past its expiration date, it is essential to evaluate the cheese carefully before doing so. The expiration date is often a guideline for quality rather than safety. If the cheese has been stored correctly and shows no signs of spoilage, it may still be safe to eat, though the texture and flavor might not be as desirable.
Always conduct a sensory check before consuming any cheese past its date. Look for any changes in color, smell, or texture. If there are any indicators of spoilage, it’s best to err on the side of caution and discard the cheese to ensure your safety.
Can I freeze vacuum sealed cheese?
Yes, you can freeze vacuum sealed cheese to extend its shelf life further. Freezing is an excellent option for preserving both hard and some semi-soft cheeses. When properly vacuum sealed, cheese can last up to a year in the freezer without losing too much of its flavor or texture. However, keep in mind that freezing may alter the texture, making it crumbly or grainy once thawed.
To freeze vacuum sealed cheese, make sure it is tightly sealed to prevent freezer burn. After thawing, it is often best to use the cheese in cooked dishes where the texture is less noticeable. This method ensures that you can enjoy the cheese long after its original shelf life has expired while minimizing texture changes.
What types of cheese are best suited for vacuum sealing?
Hard and semi-hard cheeses are generally the best candidates for vacuum sealing. Cheeses like Cheddar, Gouda, Parmesan, and Swiss respond well to vacuum sealing due to their lower moisture content, which reduces the risk of spoilage. These types of cheeses can be vacuum sealed effectively and can maintain their flavor and texture for extended periods.
On the other hand, soft cheeses such as Brie and fresh cheeses like Mozzarella may not fare as well. They can become overly moist and develop an undesirable texture when vacuum sealed. If you must vacuum seal soft cheeses, consider using it within a few weeks for the best quality. Experiment with different cheese types to find what works best for you!
Can I reuse vacuum sealed cheese packaging?
Reusing vacuum sealed cheese packaging is not generally recommended. Once the original packaging has been opened, it may no longer provide an airtight seal, and the risk of contamination increases. Additionally, remnants of cheese oils and bacteria can remain in the packaging, which could affect the quality and safety of future items stored in it.
If you plan to store cheese again after it has been opened, it is best to use new vacuum seal bags or other airtight containers designed for food storage. This approach helps ensure that the cheese remains fresh and safe to eat while minimizing the risk of spoilage or contamination.
