Swiss cheese is a much-loved variety of cheese that is known for its distinctive holes, which are formed by carbon dioxide accumulation during the maturation process. These holes are known as eyes, and the cheese is classified as a Swiss-type or Alpine cheese. Swiss cheese is made from cow's milk and is a good source of calcium and protein, contributing to a healthy diet when consumed in moderation. It has a nutty and sweet flavor, and the larger the eyes, the more pronounced the taste. While some people enjoy the sharp flavor of Swiss cheese, others find it too strong and pungent. It is often used in sandwiches, grilled cheese, or as a topping on pasta.

Nutty and sweet flavour
Swiss cheese is made from cow's milk and is known for its large holes, which are formed by carbon dioxide accumulation during the maturation process. These holes, known as "eyes", indicate a stronger flavour and a longer maturation process. The larger the eyes, the more pronounced the flavour, as a longer fermentation period gives bacteria more time to act.
The distinctive nutty and sweet flavour of Swiss cheese is due to the 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.), and Propionibacterium (Propionibacterium freudenreichii subsp.). In the later stages of production, the 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", while the acetate and propionic acid give Swiss cheese its nutty and sweet flavour.
Swiss cheese is produced in many countries, including the United States, Finland, Estonia, and Ireland, and is sometimes made with pasteurized or part-skim milk, unlike the traditional Swiss cheese made with raw milk. The typical annual production of Swiss cheese in the United States alone is approximately 330 million pounds.
The flavour of Swiss cheese is often described as sharp and pungent, and it is commonly used in sandwiches, grilled cheese, or melted on top of dishes such as pasta bakes. Some people may not enjoy the strong flavour of Swiss cheese, finding it too overpowering or preferring milder varieties of cheese.

Distinctive appearance
Swiss cheese is a generic term for any variety of cheese that resembles Emmental, a yellow, medium-hard cheese that originated in the Emmental region of Switzerland. Swiss cheese is now produced in many countries, including the United States, Finland, Estonia, and Ireland. The term "Swiss cheese" does not imply that the cheese is made in Switzerland, and there are hundreds of cheeses to choose from in Switzerland itself.
Swiss cheese has a distinctive appearance due to the holes that form during the maturation process. These holes are known as "eyes," and the cheese is said to be "blind" when it lacks these holes. The presence of holes in Swiss cheese is the result of carbon dioxide accumulation in the cheese during maturation. The larger the eyes in Swiss cheese, the more pronounced its flavour, as a longer fermentation period gives bacteria more time to act. This poses a challenge for cheese manufacturers, as cheese with large eyes does not slice well and tends to fall apart in mechanical slicers. As a consequence, US industry regulators have reduced the minimum eye size for Swiss cheese to obtain the Grade A stamp.
The holes in Swiss cheese have long been a source of fascination, with various myths attempting to explain their origin. One popular belief was that the holes were caused by bacteria that produced gases, eventually forming holes in the cheese. However, the actual cause of the holes is much simpler and relates to tiny bits of hay that fall into the milk used for cheese-making. Modern sanitation practices have reduced the average hole size in Swiss cheeses, as debris such as hay dust in the milk has been eliminated.
Swiss cheese is often recognised for its nutty and sweet flavour, which results from the acetate and propionic acid produced by bacteria during the cheese-making process. The distinctive appearance and flavour of Swiss cheese have made it a popular ingredient in dishes such as fondue, grilled cheese sandwiches, and burgers.

Health benefits
Swiss cheese is a medium-hard cheese, typically made from cow's milk, and is known for its distinctive large holes. It is a good source of protein and calcium, which provide several health benefits.
Protein is essential for muscle growth and repair, and Swiss cheese is a complete protein source, containing all nine essential amino acids. A diet high in protein has been linked to increased muscle mass and strength, and can also help with weight loss and reducing blood sugar levels. Swiss cheese is also a good source of calcium, which supports bone health and contributes to healthy blood flow.
Swiss cheese contains probiotics, specifically propionbacterum freudenreichii, a good bacteria that boosts immune system functions and contributes to gut health. It also has anti-inflammatory properties, which can reduce the risk of disease and slow ageing.
However, it is important to consume Swiss cheese in moderation as part of a balanced diet. Swiss cheese contains fat, salt, and lactose, which could be detrimental to some people's health. It has higher levels of sodium and fat, which could increase the risk of high blood pressure and cardiovascular disease. Those who are lactose intolerant should also avoid Swiss cheese, as it may cause digestive issues.

Different textures
Swiss cheese is a medium-hard cheese made from cow's milk. It is known for its distinctive holes, known as "eyes", which are formed by carbon dioxide accumulation during the maturation process. The presence and size of these holes are indicators of the strength of flavour and length of maturation—the larger the eyes, the stronger the flavour and the longer the maturation period.
The texture of Swiss cheese varies depending on the size of the eyes. A longer fermentation period gives the bacteria more time to act, resulting in larger holes and a more crumbly texture that does not slice well. This poses a problem for mechanical slicers, and as a result, US industry regulators have reduced the minimum eye size for Swiss cheese to receive a Grade A stamp.
On the other hand, Swiss cheese with smaller eyes tends to have a milder flavour and a firmer, denser texture that holds together better when sliced. Examples of Swiss cheeses with small holes include Baby Swiss and Lacy Swiss, which are two varieties of American Swiss cheese. Baby Swiss is made from whole milk, while Lacy Swiss is made from low-fat milk.
The texture of Swiss cheese can also vary depending on the age of the cheese. Aged Swiss cheese tends to have a sharper, more intense flavour and a harder, drier texture compared to younger Swiss cheese. Some people prefer to snack on milder Swiss cheese, while others enjoy the stronger flavour of aged Swiss cheese when it is melted on sandwiches or in grilled cheese.

Variety of Swiss cheese
There are hundreds of varieties of Swiss cheese, most of which are made using cow's milk. Some of the most well-known types of Swiss cheese are Emmental (or Emmenthal) and Gruyère. Emmental is named after the Emme Valley in the canton of Bern, and Gruyère is named for the walled city in the Fribourg canton. Both of these cheeses are known for their trademark holes, which are caused by tiny bits of hay that fall into the milk during the cheese-making process.
Other varieties of Swiss cheese include Sbrinz, which has been made in central Switzerland for more than two millennia, and Tête de Moine, which is known for its bold flavors and texture. Appenzeller, made in the Appenzellerland region of northeast Switzerland for over 700 years, is another type of Swiss cheese with a bold, spicy flavor. The secret to its unique personality is the herbal brine rubbed on the exterior of the wheel as it begins to mature. This combination of wine, herbs, spices, and occasionally brandy significantly influences the flavor and texture of the cheese.
