Cheese is a beloved ingredient in many households, known for its rich flavors and versatility in a variety of dishes. However, storing cheese properly can sometimes be a challenge. Vacuum sealing has become a popular method for prolonging the shelf life of various food items, including cheese. In this article, we will explore how long vacuum sealed cheese lasts in the refrigerator, how to store it properly, and tips to maintain its freshness.
Understanding Vacuum Sealing
Vacuum sealing is a process where air is removed from a bag or container before it is sealed, creating an airtight environment. This method significantly reduces the number of bacteria that can proliferate, thereby extending the shelf life of food products. When it comes to cheese, vacuum sealing provides several benefits:
- Extended Shelf Life: By removing air, vacuum sealing can slow down the oxidation process, preventing spoilage.
- Prevention of Freezer Burn: When frozen, vacuum sealed cheese is not exposed to air, minimizing the risks of freezer burn.
However, it’s important to understand the different types of cheese and how vacuum sealing affects their longevity.
Types of Cheese and Their Storage Needs
Different cheeses have varying moisture contents, fat levels, and age profiles which affect their storage. Generally, cheese can be categorized into three main types:
1. Hard Cheeses
Hard cheeses like Parmesan, Pecorino, and aged Cheddar are known for their low moisture content. These cheeses generally have a longer shelf life, even when vacuum sealed. When stored properly in a vacuum-sealed bag in the fridge, they can last:
6 Months to 1 Year
2. Semi-Hard and Semi-Soft Cheeses
Semi-hard cheeses like Gouda and Gruyère and semi-soft cheeses such as Havarti or Fontina have moderate moisture content. These cheeses can typically last:
3 to 6 Months
when vacuum sealed and stored in the refrigerator.
3. Soft Cheeses
Soft cheeses like Brie, Camembert, and cottage cheese have a higher moisture content and are more susceptible to spoilage. Therefore, when vacuum sealed, they generally last:
1 to 2 Weeks
in the fridge, although their quality may diminish more quickly than harder varieties.
How to Properly Vacuum Seal Cheese
To maximize the shelf life of your cheese, proper vacuum sealing is crucial. Below are steps to effectively vacuum seal cheese:
1. Choose the Right Cheese
Make sure to select cheese that is fresh and free of any signs of spoilage. The quality of the cheese at the time of sealing will affect its longevity.
2. Cut to Size
If you’re sealing a larger block of cheese, consider cutting it into smaller portions. This allows for easier use and avoids repeated openings of the vacuum-sealed package, which can expose the cheese to air and contaminants.
3. Use Vacuum Seal Bags
Opt for high-quality vacuum seal bags that are specifically designed for long-term storage. These bags are thicker and more durable than regular plastic bags and will provide a better seal against air infiltration.
4. Vacuum Seal Properly
Place the cheese in the vacuum seal bag, making sure not to overcrowd it. Follow the instructions on your vacuum sealer to ensure that air is completely removed and the bag is sealed tightly.
5. Label and Date

Be vigilant about checking your vacuum-sealed cheese regularly. If you notice any signs of spoilage such as off-odors, excessive moisture, or mold, it’s best to discard it.
Signs Your Vacuum Sealed Cheese Has Gone Bad
Even when vacuum sealed, cheese can eventually spoil. It’s essential to be aware of the signs that indicate your cheese is no longer safe to eat:
1. Unpleasant Odors
If the cheese emits a foul smell that wasn’t there when you sealed it, this is a clear indicator of spoilage.
2. Texture Changes
If the cheese becomes excessively slimy or develops a dry, hardened crust, it is likely past its prime.
3. Mold Development
While some mold is normal in certain cheeses, if you notice green, black, or other unusual mold growth on vacuum-sealed cheese, it’s better to err on the side of caution and discard it.
Freezing Vacuum Sealed Cheese
If you want to extend the shelf life of your cheese even more, consider freezing it after vacuum sealing. Freezing can be a great way to store cheese that you won’t use within the standard refrigerated timeframe. Depending on the type of cheese, here’s how long you can expect it to last when frozen:
| Type of Cheese | Freezer Shelf Life |
|---|---|
| Hard Cheeses | Up to 1 Year |
| Semi-Hard/Semi-Soft Cheeses | 6 to 8 Months |
| Soft Cheeses | 3 to 6 Months |
Freezing Tips
To ensure the best quality when freezing cheese, consider the following tips:
- Thaw in the Fridge: Always thaw cheese in the refrigerator rather than at room temperature to maintain texture and flavor.
- Avoid Refreezing: Once thawed, do not refreeze cheese as this can adversely affect its texture and taste.
Conclusion
Vacuum sealing cheese is an effective way to extend its shelf life while preserving its flavor and texture. Understanding the different types of cheese and how they react to vacuum sealing is crucial for optimal storage. When stored in the refrigerator, vacuum-sealed hard cheeses can last up to a year, while soft cheeses should be consumed within a couple of weeks.
By following the proper vacuum sealing techniques and storage practices outlined in this article, you can enjoy your cheese for longer periods without compromising quality. So go ahead, vacuum seal your favorite cheeses, and relish their delicious flavors whenever you’re ready to indulge!
