Swiss cheese is a type of hard cheese that typically ages well. Proper sealing and storage are key factors in preserving Swiss cheese, and it can last for months or even years beyond its best-by date if stored unopened and untouched by oxygen. The development of holes in Swiss cheese, a result of intentional worm infestation in traditional production methods, is a sign of aging and hardness according to the Shach and Taz, early poskim authorities. While expiration dates on cheese products are often arbitrary, consumers should be cautious of mold on soft cheeses and significant changes in texture and taste, which may indicate spoilage.

Swiss cheese sealed and stored properly can last for months
Proper sealing and storage are crucial factors in determining how long Swiss cheese will last. When properly stored, Swiss cheese can last for several months or even longer.
Swiss cheese, a hard cheese variety, is known for its distinctive holes, which are formed during the aging process. The aging process of Swiss cheese typically ranges from 3 to 4 months, during which time the cheese develops its unique flavour and texture. However, it's important to note that the aging process also makes Swiss cheese more susceptible to mold growth.
To ensure the longevity of Swiss cheese, proper sealing is essential. Vacuum sealing or airtight packaging can significantly extend the shelf life by preventing oxygen exposure, which is the key factor in food spoilage. When Swiss cheese is properly sealed and stored, it can be safe to consume even beyond its "best before" date.
The "best before" or "expiration" dates on cheese products are not always accurate indicators of whether the cheese is still edible. These dates are often arbitrary and may be set by producers to encourage consumers to dispose of the product prematurely and purchase more. In the case of Swiss cheese, as long as it is properly sealed and stored, it can remain edible and maintain its quality for several months.
It is important to regularly inspect Swiss cheese for any signs of spoilage. Mold growth on hard cheeses like Swiss cheese typically affects only the surface and can be cut away without compromising the safety of the rest of the cheese. However, it is crucial to use common sense and avoid consuming cheese that exhibits significant mold growth or any other noticeable signs of deterioration.

Swiss cheese is considered hard cheese, which can be consumed even after the best-before date
Swiss cheese is considered a hard cheese, and it can be consumed even after its best-before date. Hard cheeses are preserved foods, and as long as they are properly stored, they can last for much longer than their best-before dates. Proper storage includes keeping the cheese sealed and vacuumed, which prevents oxygen—the key element that makes food go bad—from spoiling the cheese.
Swiss cheese is considered hard cheese because it has developed holes, which in the old days were made by worms. The Shach (YD 89 s.k. 15) and Taz (ibid. s.k. 4), among other major early poskim, explain that cheese is considered hard if it is six months old or has these holes. This classification of Swiss cheese as hard cheese is important in the context of kosher dietary laws, which require a waiting period after consuming hard cheese before eating meat.
The best-before date on Swiss cheese, or any cheese, is not a firm expiration date. In the US, there are no regulations on date marking for cheese, and producers can put an expiration date or best-buy date on their products that are essentially arbitrary. The best-before date is a guarantee from the producer that the cheese will not change in quality up to that date in terms of taste, feel, and smell. However, it does not mean that the cheese is unhealthy to eat after this date.
As long as the Swiss cheese is properly stored, it can be consumed after its best-before date. The risk of consuming expired food is minimal with dairy products because when they go bad, they also taste bad. So, as the saying goes, "if it tastes good, it's good." However, it is important to inspect the cheese for mould before consuming it. While mould on hard cheese usually does not penetrate deeply and can be cut out, fuzzy mould indicates that the cheese should be discarded.

Swiss cheese gets holes from worms during the ageing process
It is a common misconception that Swiss cheese gets its holes from worms during the ageing process. In reality, the holes in Swiss cheese are caused by carbon dioxide gas bubbles that form during the fermentation process. This occurs when bacteria, specifically Propionibacterium freudenreichii, feed on the lactose in the cheese and produce carbon dioxide as a byproduct. The carbon dioxide gas gets trapped in the cheese, creating air pockets or "eyes" that eventually become the characteristic holes. The size and distribution of these holes can vary depending on factors such as the type of cheese, the ageing process, and the specific bacteria used.
For example, Emmental cheese, a type of Swiss cheese, typically has larger and more irregular holes due to the high levels of carbon dioxide produced during fermentation. On the other hand, other types of Swiss cheese, like Gruyère, may have smaller and more evenly spaced holes or even no holes at all. The temperature and pressure at which the cheese is aged also play a crucial role in the formation of holes. Swiss cheese is usually aged at around 70°F (21°C), which is optimal for bacterial growth and carbon dioxide production. The pressure of the cheese wheel helps to trap the bubbles, preventing them from escaping.
While some cheeses, like Casu marzu, do contain live maggots or worms, Swiss cheese is made using a controlled fermentation process that does not involve insects or worms. It is possible to make Swiss cheese without holes by using different bacteria or controlling the fermentation process to reduce carbon dioxide production. However, this would result in a cheese with a significantly different taste and texture from traditional Swiss cheese. The holes in Swiss cheese are considered a desirable feature and play a role in the cheese's flavour and texture. Larger holes indicate a longer fermentation period and a stronger taste, while cheese with larger holes tends to be crumbly and may not slice well.
The ageing process for Swiss cheese can vary depending on the specific type and the desired flavour and texture. Standard Swiss cheese is typically aged for a maximum of four months, while some varieties are aged for longer periods. For instance, Hook's Swiss cheese is aged for three years, resulting in a nuttier and tangier flavour. Baby Swiss cheese, on the other hand, is aged for several months, resulting in a softer and creamier texture. The ageing process not only enhances flavour and texture but also serves a practical purpose, as the cheese loses moisture and gains firmness over time.

Swiss cheese can be consumed after the best-before date if it tastes good
Swiss cheese is considered a hard cheese, and as such, it can be consumed after its best-before date as long as it still tastes good. While there are no regulations in the US regarding date marking on cheese, it is generally safe to consume Swiss cheese past its best-before date if it has been stored properly.
The key factor in determining whether Swiss cheese is still edible is the presence of mold. Hard cheeses, like Swiss cheese, can develop mold on the surface, which can be cut off without affecting the rest of the cheese. However, it is important to examine the cheese carefully and ensure that the mold has not penetrated deeply into the cheese.
Additionally, the taste and texture of Swiss cheese can change over time. Even if the cheese is past its best-before date, it may still be safe to consume if it has a potent taste or a brittle texture similar to aged cheeses. These characteristics indicate that the cheese has continued to age and develop flavor, and it can be treated as an aged cheese.
Proper storage is crucial in determining the edibility of Swiss cheese past its best-before date. If the cheese is properly sealed and vacuumed, it can last for months or even a year or more. Oxygen is the key element that causes food to spoil, so an airtight seal can significantly extend the shelf life of Swiss cheese.
It is important to use common sense and trust your senses when assessing whether Swiss cheese is still edible. Look at it, smell it, feel it, and taste it. If the cheese looks, smells, and tastes fine, it is likely safe to consume, even if it is past its best-before date. However, if there is any doubt or if the cheese shows signs of spoilage, it is best to discard it.

Swiss cheese should be discarded if it has fuzzy mould
Swiss cheese is a type of hard cheese. Hard cheeses are preserved foods, and as such, they can last a long time if stored properly. However, it is important to distinguish between the 'best before' date and the expiration date of food products, including Swiss cheese. The 'best before' date indicates that the producer guarantees no change in the quality of the product up to this date. The expiration date, on the other hand, suggests that it may be unhealthy to consume the product after this date.
While hard cheeses can be consumed past their 'best before' date, it is generally recommended to follow the expiration date for safety reasons. That being said, the presence of mould on hard cheese does not always mean it has expired. If mould is present on a soft cheese, it is recommended to discard the entire product. However, mould on hard cheese usually does not penetrate deeply and can be cut away.
In the case of fuzzy mould on Swiss cheese, it is recommended to discard the cheese entirely. Fuzzy mould indicates that the cheese has been forgotten for too long and is no longer safe for consumption. This is supported by a Reddit user who states that "The only cheeses I wouldn't eat are the ones that get the fuzzy mould on them after you forget them for too long".
It is important to note that the United States does not have specific regulations regarding date marking on cheese. As a result, producers can arbitrarily determine expiration dates. Therefore, it is essential to use common sense and consider the appearance, smell, and taste of the cheese to determine if it is still edible. However, it is always recommended to prioritise your health and safety, and when in doubt, it is better to discard the cheese to avoid any potential health risks.
