Swiss cheese is a semi-hard cheese with a relatively long shelf life. When unopened, it can last for several months past its 'best by' date when kept in the refrigerator. Properly 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. However, it's important to inspect your cheese for signs of spoilage, such as mould, off colours, unusual textures, or a stronger smell, before consuming it, regardless of the 'best by' date.

Unopened Swiss cheese can last for up to 6 months in the fridge
Swiss cheese is a semi-hard cheese, which means it has been cooked and pressed but not aged. This means it contains more moisture than hard cheeses. As a result, Swiss cheese has a relatively long shelf life, but it is shorter than that of hard cheeses.
If you want to extend the shelf life of Swiss cheese even further, you can freeze it. To do this, cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty aluminium foil, plastic freezer wrap, or a heavy-duty freezer bag. When properly stored, Swiss cheese will maintain its best quality for about 6 to 8 months in the freezer but will remain safe to consume beyond that time.
Once Swiss cheese is opened, it will last for several weeks in the refrigerator. However, if there are signs of spoilage, such as mould, darkening, or a stronger smell, the cheese should be discarded. It is important to inspect Swiss cheese before consuming it, as some people are more sensitive to spoiled food than others. If you are pregnant, elderly, or have a compromised immune system or certain health conditions, it is advisable to avoid consuming Swiss cheese that shows any signs of spoilage.

Properly stored, Swiss cheese can be safe to eat beyond 6-8 months in the freezer
Swiss cheese is a semi-hard cheese with a relatively long shelf life. When unopened, it can last for several weeks to a few months past its 'best by' date when stored in the refrigerator. However, the shelf life of Swiss cheese can be significantly extended by storing it in the freezer.
When storing Swiss cheese in the freezer, it is important to follow proper procedures to ensure its quality and safety. First, cut the cheese into portions no larger than half a pound each. Then, wrap the portions tightly in heavy-duty aluminum foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. By following these steps, Swiss cheese can be safely stored in the freezer beyond the recommended 6-8 months, as the freezing temperature of 0°F will keep it safe indefinitely.
It is important to note that the quality of the cheese may deteriorate over time, even if it remains safe to consume. The recommended freezer time of 6-8 months is based on maintaining the best quality for the cheese. After this period, the cheese may start to lose some of its flavour or texture.
When thawing frozen Swiss cheese, it is best to defrost it in the refrigerator. An unopened chunk of Swiss cheese that has been defrosted in the fridge can be kept for an additional 3 to 4 days before using it. If the cheese is thawed in the microwave or in cold water, it should be consumed immediately.
It is always important to inspect Swiss cheese for any signs of spoilage, regardless of its storage method or 'best by' date. Signs of spoilage may include mould, discolouration, changes in texture, or an off or sour flavour. If mould is present, cut away at least one inch around and below the mouldy area without touching the mould with your knife, and re-cover the cheese in fresh wrap.

Signs of spoilage include mould, discolouration, changes in texture, and off or sour flavours
Swiss cheese is a semi-hard cheese with a relatively long shelf life. When unopened, it can last for several months to about six months past the 'best by' date if kept in the refrigerator. Freezing an unopened chunk of Swiss cheese can further extend its shelf life, maintaining optimal quality for about 6 to 8 months.
However, it's important to inspect Swiss cheese for signs of spoilage, especially if it's past its 'best by' date. The signs of spoilage include mould, discolouration, changes in texture, and off or sour flavours. Mould on Swiss cheese indicates that it has spoiled and should be discarded. While it is safe to cut away the mouldy portion and consume the rest of the cheese for some varieties of cheese, this does not apply to Swiss cheese.
Discolouration, such as significant changes in colour like yellowing or browning, can indicate that the Swiss cheese has spoiled. Changes in texture, such as the cheese becoming overly dry, crumbly, or slimy, are also signs of spoilage. If the Swiss cheese has developed an off or sour flavour, it is likely spoiled and should not be consumed.
In addition to these signs, it's important to consider the storage conditions and duration of storage. Swiss cheese should be kept refrigerated at all times, and proper storage can help extend its shelf life. However, even with proper storage, Swiss cheese will eventually spoil, and the risk of spoilage increases with extended storage durations. Therefore, it is crucial to regularly inspect the cheese for any signs of spoilage and use your best judgment before consumption.

Hard cheeses like Swiss cheese can be safe to eat past their expiration date if properly stored
Swiss cheese is a semi-hard cheese with a relatively long shelf life. When unopened, it can last several months past its 'best by' date if kept in the refrigerator. Properly stored, an unopened chunk of Swiss cheese will last for about six months in the refrigerator. If you want to extend its shelf life, you can freeze an unopened chunk of Swiss cheese. To do this, cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. When properly stored, Swiss cheese will maintain its best quality for about six to eight months in the freezer but will remain safe to eat beyond that time.
Hard cheeses, in general, tend to have a longer shelf life than soft cheeses. This is because they contain less moisture and are therefore less prone to spoilage from bacteria. Hard cheeses like Swiss cheese, Cheddar, Parmesan, and Gouda are more likely to be safe to eat past their expiration date if they are properly stored and show no signs of spoilage. If you notice mould on hard cheese, you can cut off at least one inch around and below the mouldy spots and the rest of the cheese will still be good to eat. However, it's important to note that some types of mould produce very dangerous toxins, so always practice food safety and inspect your cheese before eating it.
The shelf life of hard cheese is influenced by several factors, such as the type of cheese, the processing method, packaging date, exposure to heat, and storage conditions. Proper storage is crucial to extending the shelf life of hard cheeses. In the case of Swiss cheese, it should be kept unopened and refrigerated at all times. To maximise its shelf life, do not open the package until you are ready to use it.
While hard cheeses can be safe to eat past their expiration date, it's important to use your best judgment and inspect the cheese for any signs of spoilage. Some common traits of cheese going bad include a darker colour, harder texture, and a stronger smell. If you notice any of these signs or see mould growth, it's best to discard the cheese. Additionally, if you have a compromised immune system, are pregnant, elderly, or have certain health conditions, it's generally advisable to be more cautious and avoid consuming foods that show any signs of spoilage.

Soft cheeses have a shorter shelf life than semi-hard cheeses like Swiss cheese
The shelf life of cheese depends on several factors, including the type of cheese, how it has been stored, and the degree of spoilage. Soft cheeses tend to spoil more quickly than semi-hard or hard varieties because they contain more moisture, making them more prone to bacterial growth.
Soft cheeses like Brie, Camembert, goat's cheese, mozzarella, feta, cottage cheese, cream cheese, and ricotta are more perishable and typically last for about a week to a few weeks in the refrigerator after opening. Fresh cheeses like ricotta and cottage cheese have an even shorter shelf life and are best consumed within a week or two of opening. If you see signs of mould on soft cheese, throw it out.
On the other hand, semi-hard cheeses like Swiss cheese, cheddar, gouda, and provolone have a relatively long shelf life. An unopened chunk of Swiss cheese will last for about 6 months in the refrigerator and can be frozen for 6 to 8 months to maintain its best quality. Even after the "best by" date, Swiss cheese will typically remain safe to use for about 6 months if unopened and refrigerated. If mould is present, cut away at least 1 inch (2.5 cm) around and below the mouldy area and re-cover the cheese.
Hard cheeses like cheddar, parmesan, and gouda are more likely to be safe to eat past their expiration date if properly stored and show no signs of spoilage. Hard cheeses can be inspected for mould, off colours, unusual textures, or unpleasant odours, and the mouldy portions can be cut off and discarded before consuming the rest of the cheese.
It's important to note that "best by" dates are guidelines for quality rather than safety, and cheese may still be safe to eat past this date if it shows no signs of spoilage. However, it may not have the optimal flavour or texture. Proper storage, such as keeping cheese sealed and refrigerated, can help extend its shelf life.
