Swiss cheese is a broad term for any variety of cheese that resembles Emmental cheese, a medium-hard cheese that originated in Switzerland. The term does not imply that the cheese is made in Switzerland, and it is now produced in many countries, including the United States, Finland, Estonia, and Ireland. The taste of Swiss cheese is influenced by several factors, including the type of milk used, the bacteria and enzymes added during production, and the length of the aging process. Some people find the taste of Swiss cheese unpleasant, describing it as pungent and overpowering, while others appreciate its nutty and sweet flavor with mild sweetness and earthy undertones.

Swiss cheese is made using century-old techniques passed down through generations
The curds are then soaked in a brine solution, absorbing salt and releasing water. During this process, the bacteria expand and release carbon dioxide, creating the distinctive holes that make Swiss cheese famous. The cheese is then heated and cooled multiple times, and it is deemed ready for processing and inspection when dime-sized holes, or "eyes", are present. The cheese is then poured into moulds, allowing the whey to escape, and it is compressed to remove additional liquid. The cheese is then given a "passport" for identification and placed in a brine bath, where it absorbs more salt and releases whey.
The traditional methods of Swiss cheese-making have been refined over the years, with each creamery having its own specific tests to safeguard the production of unpasteurised milk. The art of Swiss cheese-making involves a careful balance of bacteria, temperature control, and curd manipulation to create the desired flavour, texture, and appearance. The process has been passed down through generations, with each generation contributing to the refinement of the craft.

The bacteria used in production give Swiss cheese its nutty and sweet flavour
The distinctive nutty and sweet flavour of Swiss cheese is the result of bacteria used in its production. Three types of bacteria are used in the production of Swiss cheese: Streptococcus thermophilus, Lactobacillus (L. helveticus or L. delbrueckii subsp. bulgaricus), and Propionibacterium (Propionibacterium freudenreichii subsp. shermani). In the later stages of cheese production, propionibacteria consume the lactic acid excreted by the other bacteria and release acetate, propionic acid, and carbon dioxide gas. The carbon dioxide forms the bubbles that create the "eyes" in Swiss cheese, while the acetate and propionic acid are responsible for its nutty and sweet flavour.
The flavour of Swiss cheese is also influenced by the size of the eyes, with larger eyes indicating a more pronounced flavour due to the longer fermentation period. This extended fermentation gives the bacteria more time to act and develop the flavour of the cheese. However, cheese with large eyes does not slice well and tends to come apart in mechanical slicers, leading to industry regulations on eye size for commercially produced Swiss cheese.
The flavour of Swiss cheese is further enhanced by the aging process, which can last for several months. During this time, the flavours mature and intensify, contributing to the nuanced taste appreciated by Swiss cheese enthusiasts. The process of refining and maturing the cheese, known as affinage, requires careful monitoring of temperature and humidity to ensure the cheese reaches its peak of flavour and quality.
Additionally, the milk used in Swiss cheese production also plays a role in its flavour. The diet of the cows can influence the taste of the milk, resulting in subtle variations in the cheese. For example, cheese made from milk produced by cows grazing in high alpine meadows may taste different from cheese made from milk produced by cows grazing in the lowlands. The addition of "secret stuff" or rennet, a substance passed down through generations of cheesemakers, also contributes to the unique flavour of Swiss cheese.

The size of the holes in Swiss cheese, known as eyes, impacts its flavour
The holes in Swiss cheese, known as "eyes", are crucial in defining the texture and flavour of the cheese. The size of these eyes influences the flavour of Swiss cheese. In general, larger eyes in Swiss cheese indicate a more pronounced flavour. This is because a longer fermentation period allows bacteria more time to act, creating a stronger flavour. On the other hand, smaller eyes result in a milder flavour, as the cheese has a shorter fermentation period, and less time for bacteria to act.
Swiss cheese is made using three types of bacteria: Streptococcus thermophilus, Lactobacillus (L. helveticus or L. delbrueckii subsp. bulgaricus), and Propionibacterium (Propionibacterium freudenreichii subsp. shermani). The interaction of these bacteria with the milk used gives Swiss cheese its distinctive flavour. The milk itself contributes flavour depending on the diet of the cow it came from. For example, cheese made from the milk of cows that graze in high alpine meadows will taste different from cheese made from the milk of cows that graze in the lowlands.
The "eyes" of Swiss cheese are formed during the late stages of cheese production when propionibacteria consume the lactic acid excreted by the other bacteria and release acetate, propionic acid, and carbon dioxide gas. The carbon dioxide forms bubbles that develop into the eyes. The larger the eyes, the more carbon dioxide has been produced, and the more bacteria have acted to create a stronger flavour.
The ageing process also plays a significant role in the flavour of Swiss cheese. Extended ageing, which can last for several months, allows the flavours to mature and intensify, contributing to the nuanced taste that Swiss cheese enthusiasts appreciate. This process requires skilled monitoring of temperature and humidity to ensure the cheese reaches its peak of flavour and quality.

The aging process intensifies the flavour of Swiss cheese
The aging process is a key stage in Swiss cheese-making that significantly intensifies its flavour. This process, known as affinage, involves the skillful monitoring of temperature, humidity, and time to ensure that each wheel of Swiss cheese reaches its peak of flavour and quality. The extended aging period, which often lasts for months, allows the flavours to mature and intensify, contributing to the nuanced and distinctive taste that Swiss cheese enthusiasts know and love.
The longer fermentation period gives bacteria more time to act, resulting in larger "eyes" in the cheese and a more pronounced flavour. These "eyes" or holes are not merely aesthetic; they are crucial in defining the cheese's texture and imparting a distinct visual identity. The larger the eyes, the more intense the flavour, as the fermentation process allows the bacteria to develop complex flavours.
The unique flavour profile of Swiss cheese is a harmonious blend of various elements, ranging from mild sweetness to nutty undertones and a hint of tanginess. The mild sweetness adds a pleasant note that makes the cheese appealing to a broad audience, while the nutty undertones contribute complexity and depth of flavour.
The aging process also influences the texture of Swiss cheese, which strikes a delightful balance between creamy and firm. This interplay between smoothness and the occasional small, crystalline crunch adds depth to the overall sensory experience, making Swiss cheese a certified hit for the taste buds.
In summary, the aging process plays a crucial role in intensifying the flavour of Swiss cheese. Through extended aging, the flavours mature and develop, resulting in the nuanced and distinctive taste that has made Swiss cheese a beloved choice on cheese boards and in culinary creations around the world.

Swiss cheese made from cows grazing in high alpine meadows tastes different from those grazing on lowland grass
Swiss cheese, or what is known as "Swiss cheese" outside of Switzerland, gets its distinct character from the requirements of its production process, which takes place in the summer on high Alpine grasslands. The cows graze on fresh grass or hay and their milk is collected daily and heated over wood in copper vats. The milk is then stirred by hand or with a "cheese harp", a set of metal wires. The curds are cooked at high temperatures and pressed to reduce moisture content, and the cheese is formed into rounds or "wheels" with a hard rind to be kept and transported.
The taste of Swiss cheese, therefore, is influenced by the milk and what the cows eat. Many agree that they can taste the difference between cheeses made from cows grazing in high alpine meadows versus those grazing on the grass in the lowlands. The milk from cows in the high alpine meadows is described as floral and herbaceous, with light, gentle, flowery notes and a hint of salt. The cheese made from this milk tends to have nutty, fruity, spicy, or chocolatey notes.
On the other hand, cows grazing on lowland grass likely produce milk with a different flavour profile. While the specific taste may vary depending on the exact composition of the grass in these lowlands, it can be assumed that the milk may have a less herbaceous or floral character.
In addition to the type of grass the cows graze on, other factors can also influence the taste of Swiss cheese. The period of maturation, the method of making the cheese, and the specific breed of cow can all play a role in the final product's taste.
