The Longevity Of Swiss Cheese: Storage Tips And Tricks

Swiss cheese is a tasty and versatile treat, perfect for a wine and cheese night or a sandwich. But how long does it last? The answer depends on how the cheese is stored. An unopened chunk of Swiss cheese will last for about 6 months in the refrigerator, and can be kept safe indefinitely in the freezer. Sliced Swiss cheese from the deli counter can be kept in the fridge for 6-8 months, and will remain safe for 8 months in the freezer. To keep your Swiss cheese fresh, wrap it in parchment or wax paper, then loosely in plastic wrap.

Swiss cheese in the fridge: 3-4 weeks

Swiss cheese is a tasty choice for any occasion, whether you're hosting a wine and cheese night or slapping a slice on your favourite sandwich. To get the most out of your Swiss cheese, it's important to follow certain practices for serving and storing it.

When it comes to storing Swiss cheese in the fridge, the best way to do it is by wrapping it in parchment or wax paper, rather than plastic wrap. This is because Swiss cheese, like other cheeses, is an organic food whose composition can easily change based on temperature, the surrounding air, and its ability to "breathe". When you wrap Swiss cheese tightly in plastic, you can alter its composition and flavour. To properly store Swiss cheese, wrap it first in parchment or wax paper, then loosely in plastic wrap. When stored this way, your cheese will keep in the fridge for 3 to 4 weeks.

If you want to extend the shelf life of Swiss cheese, you can freeze it. To do this, follow the same method as for refrigeration, but add a final layer of heavy-duty aluminium foil. Your cheese should last up to 6 months in the freezer using this method.

It's also important to serve Swiss cheese properly. While it's always important to refrigerate Swiss cheese until you're ready to eat it, it's best to allow the cheese to come to room temperature before serving. This can take up to an hour, but it will be worth the wait as it will allow you to enjoy the cheese at its best and fullest flavour.

Additionally, make sure to re-store your cheese properly if you have any leftovers. Cut Swiss cheese can start to lose moisture and dry out if it's not properly wrapped, so be sure to follow the same storage steps as above (paper, then plastic) to keep your cheese fresh and flavourful.

Freezing Swiss cheese: 6-8 months

Swiss cheese can be frozen and still taste good. As a semi-hard cheese, it holds up better in the freezer than softer cheeses, like Brie. Frozen blocks of Swiss tend to hold up the best and should be no less than half a pound each. It's ideal to leave blocks in their original packaging (which is usually airtight). If the packaging has been opened, a vacuum sealer is the best way to go. If you don't have a vacuum sealer, the cheese can be covered tightly in plastic wrap or aluminium foil, then placed in a freezer-safe, plastic zipper-top bag that you squeeze all of the air out of. Ensure that no moisture has made its way in, as this can cause ice crystals that affect the cheese.

Shredded, grated, and sliced Swiss can also be frozen but is harder to wrap up properly. Use clear wrap and/or a zipper-seal bag, or a vacuum-sealed, freezer-friendly container to store it. A rolling pin is a great way to push the air out of a bag containing grated cheese.

Frozen Swiss should be defrosted in the refrigerator and, once thawed, used quickly. It is typically better used melted and/or incorporated into dishes.

When frozen and stored properly, Swiss cheese should last up to six months in the freezer.

Thawing frozen Swiss cheese: 2-4 days

Swiss cheese can be frozen and stored for up to six months. When you're ready to use it, it's best to thaw it slowly in the refrigerator. This will help to maintain the cheese's texture and flavour.

To thaw frozen Swiss cheese, remove the desired amount from the freezer and place it in the fridge. It's best to leave it in the original wrapping to prevent moisture loss. Allow 24 hours for every pound of cheese to thaw completely. Once thawed, it's best to use the cheese within 2 to 4 days.

If you're in a hurry, you can use the microwave on a low power setting in short bursts, or try grating the frozen cheese directly into your recipe – it will thaw quickly as it cooks.

It's important to note that freezing and thawing Swiss cheese can alter its flavour and texture. The cheese may become slightly crumbly or grainy, and it might lose some of its complexity.

Swiss cheese in the freezer: indefinitely

Swiss cheese can be frozen and still taste good. As a semi-hard cheese, it holds up better in the freezer than softer cheeses, like Brie. However, like most cheeses, it will become more crumbly after it has been thawed. Therefore, while frozen Swiss cheese may not be ideal for a cheese platter or sandwich, it can work well in sauces or prepared dishes, such as casseroles or pasta.

To store Swiss cheese in the freezer, it is recommended to wrap it first in parchment or wax paper, then loosely in plastic wrap, and finally, add a layer of heavy-duty aluminium foil. It is best to use Swiss cheese within six months of freezing it. Frozen Swiss cheese should be defrosted in the refrigerator and, once thawed, used quickly.

While Swiss cheese can be frozen indefinitely, it is recommended to use it within 6–9 months for the best quality. This is because freezing affects the texture and quality of cheese. When cheese is frozen, small ice crystals form on the inside, disrupting its internal structure. When it is thawed, water is released, causing the cheese to dry out, become crumbly, and potentially develop a mealy texture. Frozen cheeses may also be less meltable, especially if stored for longer periods.

To summarise, Swiss cheese can be frozen indefinitely but is best enjoyed within 6–9 months. When freezing Swiss cheese, ensure it is wrapped properly to prevent freezer burn and maintain its quality. Frozen Swiss cheese is ideal for cooked dishes rather than eating fresh.

How to tell if Swiss cheese has gone bad

Swiss cheese is a versatile ingredient that can be used in sandwiches, paninis, omelettes, casseroles, burgers, cheese boards, stuffed vegetables, fondue, and quesadillas. However, it's important to know when your Swiss cheese has gone bad to avoid eating spoiled food. Here are some detailed signs to look out for:

Visual Inspection

Start by looking at your Swiss cheese. Fresh Swiss cheese should not have any mould. If you notice any green, blue, or black spots, it's time to discard the cheese.

Texture

Next, feel the texture of the cheese. Fresh Swiss cheese is characterised by a firm yet slightly springy texture. If your Swiss cheese feels slimy, rock-hard, or crumbly, it has gone bad and should be discarded.

Smell

The smell of Swiss cheese can also indicate whether it has gone bad. Fresh Swiss cheese should have a mild and nutty aroma. If you detect a strong, sour, or ammonia-like smell, it's a sign that the cheese has spoiled and should be thrown out.

Taste

If you're still unsure, you can carefully taste a small amount of the cheese. If it tastes off or bitter, it's best to discard it. However, it's important to exercise caution as consuming spoiled food can potentially make you sick.

Storage Tips

To prolong the freshness of your Swiss cheese, proper storage is essential. First, wrap the cheese in wax or parchment paper, then place it in a plastic bag or an airtight container. This allows the cheese to breathe while keeping moisture out. Store the wrapped cheese in the cheese drawer or on a stable middle shelf of your refrigerator, maintaining a temperature between 35°F and 40°F (1.6°C to 4.4°C). Additionally, ensure that you separate Swiss cheese from other types of cheese to avoid flavour transfer and potential cross-contamination.
