Swiss cheese is known for its distinctive holes, nutty flavour, and strong smell. While some people enjoy the taste, others find it disgusting, comparing it to the taste of toe fungus or socks. The smell of Swiss cheese has been described as rotten, nasty, and eye-wateringly bad. So, why does Swiss cheese smell so bad? The answer lies in the fermentation process, which involves gathering cheese curds, ageing them, and then washing them in a brine solution. This process creates a warm, moist, and salty environment that attracts bacteria (Brevibacterium linens, or B. linens) that break down proteins, fats, and sugars, releasing stinky gases.

Swiss cheese is made from cow's milk and aged for 3-4 months
Swiss cheese is a semi-hard cheese made from cow's milk and typically aged for three to four months. The cheese is known for its distinctive holes, or "eyes", and nutty flavour. It is a versatile ingredient, commonly used in sandwiches, fondue, quiches, and casseroles. Its smooth, melt-able texture and mild flavour make it easy to pair with a range of ingredients.
Swiss cheese is made from cow's milk, which is collected and left to age. The ageing process is what gives Swiss cheese, and other cheeses, their characteristic smell. The warm, moist, and salty environment of the ageing process attracts bacteria (such as Brevibacterium linens, or B. linens) that break down proteins, fats, and sugars, releasing gases that contribute to the strong odour.
While Swiss cheese is known for its nutty flavour, some have described it as tasting like socks or toe fungus. The smell has been described as similar to body odour or gym socks. The strong odour of Swiss cheese is likely due to the ageing process, which creates an optimal environment for bacteria growth, leading to the release of stinky gases.
It is important to note that not all Swiss cheeses have a strong odour. The type of milk used, the ageing process, and the chemicals used during production can all impact the final product's smell and taste. For example, using pasteurized milk can lessen the smell of Swiss cheese to some degree. Additionally, the distinctive holes in Swiss cheese are a result of the fermentation process, where bacteria produce carbon dioxide gas that becomes trapped within the cheese, creating the iconic pockets.

Swiss cheese has a nutty flavor and a stinky aroma
Swiss cheese is a semi-hard cheese made from cow's milk. It is known for its distinctive holes, or "eyes", and nutty flavour. The holes are a result of the fermentation process, during which bacteria produce carbon dioxide gas that becomes trapped within the cheese, creating the iconic pockets.
Swiss cheese has a mild flavour and a smooth, melt-able texture, making it a versatile ingredient that can be adapted for numerous dishes. However, some people find the taste and smell of Swiss cheese unpleasant, comparing it to socks or toe fungus.
One particular variety of Swiss cheese, Vacherin Fribourgeois, is noted for its strong aroma. This semi-soft cheese from the Bulle, Fribourg, and Jura regions of Switzerland has a straw-colored interior and a buttery texture. It is only produced by a limited number of artisanal cheesemakers and is hard to find. Vacherin Fribourgeois is a washed-rind cheese, which means it is washed in a brine solution during the production process. This washing step encourages the growth of pungent bacteria and yeast, resulting in the strong aroma characteristic of this type of cheese.
Another factor that can contribute to the smell of Swiss cheese is the aging process. The warm, moist, and salty environment during aging creates optimal conditions for the growth of bacteria, which can produce stinky gases.

Limburger cheese, made from cow's milk, is said to smell like feet
Limburger cheese, made from cow's milk, is notorious for its strong smell, often likened to that of feet. The cheese's pungency intensifies with age, and while it may be off-putting to some, others find it delectable. Limburger is a smear-ripened, washed-rind cheese, and its unique aroma is attributed to the presence of Brevibacterium linens, a bacterium also found on human skin, specifically responsible for foot odor.
The aging process of Limburger cheese can be divided into three stages, each offering a distinct sensory experience. In its initial stage, Limburger is mild, crumbly, and yeasty, resembling feta cheese. At this stage, its odor is relatively subdued. However, as the cheese progresses to the intermediate stage, it develops a rich and creamy texture, along with a more pronounced smell. The rind, which contributes significantly to the odor, can be washed and dried to mitigate the intensity.
The final stage of aging yields a soft, almost runny cheese that has earned the nickname "weapons-grade Limburger" due to its potent aroma, reminiscent of sweaty socks. While the smell may be overwhelming for some, Limburger cheese is considered a delicacy by many, particularly in Wisconsin, where it continues to be produced and cherished. The cheese is often paired with raw onion, rye bread, and beer, creating a distinct culinary experience that has become synonymous with the culture of the region.
The key to appreciating Limburger cheese lies in acclimating to its distinctive smell. Some suggest gradually exposing oneself to the odor, starting from a distance, and then moving closer to the cheese, a process that can be aided by a couple of drinks. While the aroma may be an acquired taste, the payoff is a rich, smooth, and buttery flavor that has captivated cheese enthusiasts worldwide. Limburger cheese, despite its pungency, represents a unique culinary tradition that has endured and thrived, with a dedicated following that appreciates its complex sensory profile.

Swiss cheese is versatile and can be used in sandwiches, salads, and fondues
Swiss cheese is a versatile ingredient that can be used in a variety of dishes, from sandwiches to salads and fondues. Its smooth, meltable texture and mild, nutty flavour make it a great complement to many recipes without being overpowering.
When used in sandwiches, Swiss cheese can be grilled to make the most of its melting quality, adding a unique twist to a classic dish. Its distinctive holes, or "eyes", are a result of the fermentation process, where bacteria produce carbon dioxide gas that becomes trapped within the cheese, creating the iconic pockets. These bubbles help to distribute warmth more evenly when the cheese is melted, making it ideal for grilled cheese sandwiches.
In salads, Swiss cheese can be cut into cubes and enjoyed cold, adding a nutty flavour twist. Its semi-hard texture and mild flavour make it a great addition to a variety of salad ingredients. For a true Swiss experience, try a Kaesesalat, a traditional Swiss cheese salad.
Fondue, a Swiss dish that gained popularity in the US in the 1960s, is another classic way to use Swiss cheese. The original version was simply stale bread dipped in melted Gruyère, but today, fondue typically includes a blend of Swiss cheeses such as Emmentaler, Vacherin Fribourgeois, Appenzeller, and Raclette, along with wine and garlic. The creamy, buttery texture of Swiss cheese makes it ideal for dipping, and its mild flavour pairs well with a variety of dippers, including bread, potatoes, apples, and vegetables.

Swiss cheese is characterised by its holes, which are a result of the fermentation process
Swiss cheese, known for its distinctive holes and nutty flavour, is a semi-hard cheese made from cow's milk. It is typically aged for three to four months and is now produced in various countries worldwide, although it originated in Switzerland. The holes, or "eyes", that Swiss cheese is famous for are a result of the fermentation process. During fermentation, bacteria produce carbon dioxide gas that becomes trapped within the cheese, creating the iconic pockets.
The holes in Swiss cheese are not just for show; they serve a practical purpose in cooking and eating. When melted, the holes help distribute warmth more evenly throughout the cheese. The cheese is versatile and can be enjoyed on its own or incorporated into various dishes, such as fondue, grilled sandwiches, casseroles, quiches, or cheese-topped dishes that require baking. Its smooth, meltable texture and mild flavour make it easy to pair with a range of ingredients, although its distinctive taste might seem lacking to those accustomed to stronger cheeses.
Swiss cheese is characterised by a slight sweetness and a nutty flavour. Some have compared its taste to toe fungus and socks, while others have described its smell as rotten, nasty, and eye-wateringly bad. However, it is important to note that the smell of Swiss cheese, or any cheese for that matter, does not indicate spoilage. The strong smell of cheese is generally attributed to the chemicals used during the washing process, which involves gathering cheese curds, ageing them, and then washing them in a brine solution. This process creates a warm, moist, and salty environment that promotes the growth of pungent bacteria and yeast, resulting in the release of stinky gases.
To determine if Swiss cheese has gone bad, look for mould in the form of blue or green blotches or check for a sour or off smell. A change in colour, such as the cheese turning yellowish or brownish, could also indicate spoilage. Proper storage can help extend the shelf life of Swiss cheese. It is recommended to store it in the vegetable drawer of the fridge, which maintains the right humidity levels, and to keep it in a sealed plastic bag or cheese paper.
