Swiss cheese is a firm, pale-yellow cow's milk cheese, often with holes, or eyes, produced when bacteria in the cheese release carbon dioxide during the aging process. The term Swiss cheese is used for any variety of cheese that resembles Emmental cheese, which originated in Switzerland. Swiss cheese is now produced in many countries, including the US, Finland, Estonia, and Ireland, and is sometimes made with pasteurized or part-skim milk, unlike the original Swiss cheese made with raw milk. Raw milk is unprocessed and unadulterated, maintaining all the original bacteria, enzymes, and flavors, which can lead to a complex, rich, and nuanced cheese. Raw Swiss cheese is made with raw cow's milk and is aged 3-8 months. It has a sweet, buttery flavor and is perfect for fondue, quiche, or snacking with fruits.

Swiss cheese is made from raw milk
Swiss cheese is a firm, pale-yellow cow's milk cheese that is now produced in many countries, including the United States, Finland, Estonia, and Ireland. The term "Swiss cheese" is used for any variety of cheese that resembles Emmental cheese, a medium-hard cheese that originated in the Emmental region of Switzerland. While Swiss cheese is now often made with pasteurized or part-skim milk, the original Swiss cheese from Switzerland was made with raw milk.
Raw milk is milk that is fresh from the cow, unprocessed, and unadulterated. It maintains all the original bacteria, enzymes, and flavors, which can lead to a complex, rich, and nuanced cheese. Raw milk cheese is made from this unpasteurized milk, and the process of pasteurization involves heating milk to kill bacteria that could potentially cause illness. While pasteurization can kill off harmful bacteria, it also eliminates beneficial bacteria and can affect the flavor of the cheese. Raw milk cheeses tend to have more vitamins B and C than pasteurized cheeses, and the leftover bacteria from the raw milk can contribute to a stronger immune system and improved gut health.
Swiss cheese made from raw milk has a distinctive appearance, with blocks or rounds of the cheese riddled with holes known as "eyes." These holes are formed during the aging process when bacteria in the cheese release carbon dioxide. The larger the eyes in Swiss cheese, the more pronounced its flavor, as a longer fermentation period gives the bacteria more time to act. However, cheese with large eyes does not slice well and tends to fall apart in mechanical slicers.
In addition to its unique appearance and flavor, Swiss cheese made from raw milk offers nutritional benefits due to the presence of beneficial bacteria. A 1995 study from Switzerland examined the safety of Swiss hard and semi-hard cheeses made with raw milk and found that the use of high curd-cooking temperatures contributed to the safety of these cheeses. While there are concerns about the potential health risks of consuming raw milk, especially for pregnant individuals, the traditional method of making Swiss cheese with raw milk preserves the nutritional qualities of the milk and results in a cheese with a rich and complex flavor profile.
Some popular varieties of Swiss raw milk cheeses include Tête de Moine, L'Etivaz, Appenzeller, Sbrinz, and Vacherin Fribourgeois. These cheeses honor the traditional cheesemaking processes and showcase the unique characteristics of Swiss cheese made with raw milk.

Raw milk is unprocessed and unpasteurized
Raw milk is milk in its most natural form, fresh from the cow (or goat, sheep, or water buffalo). It is unprocessed and unpasteurized, retaining all of its original bacteria, enzymes, and flavours. This raw milk is used to make raw milk cheese, which is simply cheese made from unpasteurized milk. Pasteurization is a process that involves heating milk to kill bacteria that could potentially make you sick. The process involves heating milk to 161° F for fifteen seconds or to 145° F for thirty minutes or more. For raw milk cheeses, this means that some of the bacteria can transfer to the cheese. While it is uncommon, diseases can be transferred through food. However, the safety and flavour of a cheese depend on the entire making and handling process, from the feed and animal to the retailers and consumers.
Swiss cheese is a firm, pale-yellow cow's milk cheese that is made in the United States and several other countries. It is modelled after Emmental cheese, which originated in Switzerland. Swiss cheese is typically made with pasteurized or part-skim milk, unlike the original Swiss cheese from Switzerland, which is made with raw milk. The term "Swiss cheese" is now used for any variety of cheese that resembles Emmental cheese. It is classified as a Swiss-type or Alpine cheese. The term is generic and does not imply that the cheese is made in Switzerland. Swiss cheese often has holes, or "eyes," which are produced when bacteria in the cheese release carbon dioxide during the aging process. The larger the eyes in Swiss cheese, the more pronounced its flavour, as a longer fermentation period gives the bacteria more time to act.
In Switzerland, approximately 80% of cheeses are manufactured from raw milk without prior heat treatment. A 1995 study in Switzerland examined the safety of Swiss hard and semi-hard cheeses, inoculating milk with high levels of pathogens such as Salmonella, Listeria, and E. coli. The authors could not detect any pathogens beyond one day of manufacture, suggesting that the high curd-cooking temperatures, high pressing temperatures, low moisture, and high ripening temperatures contributed to the safety of Swiss hard cheeses.
Raw milk cheeses are known for their bold flavours and nutritional benefits. They contain essential vitamins, minerals, and beneficial fats that can support overall health and well-being. Raw milk cheeses tend to have higher levels of vitamin B and C compared to pasteurized cheeses. The diverse array of beneficial bacteria found in raw milk cheeses can contribute to a stronger immune system and improved gut health, promoting a balanced microbiome. Additionally, raw milk cheeses develop a wider array of flavours in aged cheeses due to the natural flora, yeasts, esters, and enzymes.

Raw milk contains bacteria, enzymes, and flavours
Raw milk is milk that is fresh from the cow, unprocessed, and unadulterated. It is milk in its most natural form. Raw milk contains bacteria, enzymes, and flavours, which can lead to a complex, rich, and nuanced cheese.
Raw milk contains a diverse array of bacteria. Most of the bacteria present in raw milk are contaminants from the outside, entering the milk from sources such as soil, bedding, manure, feed, and milking equipment. However, some of the bacteria in raw milk are good bacteria. For example, Lactobacillus helveticus, which is commonly isolated from raw milk, has several traits that are desirable for cheese production. These include the rapid autolysis of the strains, which results in the release of intracellular enzymes and a reduction in bitterness and increased flavour notes in cheese. The presence of bacteria in raw milk can also contribute to colour, flavour, and textural development in cheese.
Raw milk also contains enzymes. These enzymes can impact the flavour, texture, and stability of milk and dairy products. For example, enzyme activity during milk storage can result in defects in flavour, texture, and stability. However, some enzymes in raw milk, such as plasmin, can survive pasteurization. Enzymes in raw milk can also have nutritional benefits. For example, raw milk is claimed to have a unique nutritional profile and is considered a "complete food" as it contains natural enzymes, fatty acids, vitamins, and minerals.
In addition to bacteria and enzymes, raw milk contains flavours. These flavours can lead to a rich and nuanced cheese. The flavours in raw milk can develop during the cheese-making process, with the natural flora, yeasts, esters, and enzymes contributing to a wider array of flavours in aged cheeses. The larger the "eyes" in Swiss cheese, made from raw milk, the more pronounced its flavour, as a longer fermentation period gives the bacteria more time to act.

Raw milk cheese is celebrated for flavour and scrutinized for safety
Raw milk cheese is made from milk that is unprocessed and unadulterated, retaining its original bacteria, enzymes, and flavours. This results in a complex, rich, and nuanced cheese with a depth of flavour that varies depending on the terroir of each farm and cheesemaking operation. Raw milk cheeses are also a nutritional powerhouse, packed with essential vitamins, minerals, beneficial fats, and good bacteria that support overall health and wellness.
However, raw milk cheese is also scrutinized for safety due to the potential presence of harmful bacteria that can cause diseases. Pasteurization is a process that involves heating milk to kill these bacteria, and many countries have strict regulations around raw milk cheese production and sales to ensure safety. For example, in the US, raw milk cheese must be aged for at least 60 days to naturally kill off any potential pathogens.
The scrutiny surrounding raw milk cheese is rooted in both science and culture. Historically, all cheeses were made with raw milk until the development of pasteurization. The opposition to raw milk cheese is part of a larger opposition to the homogenization of food and culture, with consumers seeking a return to authenticity and traditional methods. Additionally, the safety and flavour of raw milk cheese are dependent on the entire making and handling process, from the feed and animal care to the aging and retail of the cheese.
While raw milk cheese may pose potential health risks, these are rare, and proper handling and regulation can ensure safety. The benefits of raw milk cheese include enhanced flavour, nutritional value, and support for overall health and wellness.

Swiss cheese has distinctive holes, known as eyes
Swiss cheese is a firm, pale-yellow cow's milk cheese, often made in the United States but modelled after Emmental cheese from Switzerland. It is sometimes made with pasteurized or part-skim milk, unlike the original Swiss version, which is made with raw milk. Swiss cheese has a mild, nutty, and buttery flavour, similar to authentic Swiss cheeses like Emmental and Gruyere. It is a versatile cheese, melting well and making it a great choice for cheese sauces, sandwiches, omelettes, and pasta.
Swiss cheese has distinctive holes, known as "eyes". These holes are produced when bacteria in the cheese release carbon dioxide during the aging process. The carbon dioxide forms bubbles that slowly develop into the "eyes". The larger the eyes in a Swiss cheese, the more pronounced its flavour, as a longer fermentation period gives the bacteria more time to act.
Historically, the holes in Swiss cheese were seen as a sign of imperfection, and cheesemakers tried to avoid them by pressing the cheese during production. It is only in modern times that the holes have become an identifier of the cheese. The term "Swiss cheese" is now used for any variety of cheese that resembles Emmental cheese, and the term does not imply that the cheese is made in Switzerland.
Swiss cheese made from raw milk offers a range of nutritional benefits. Raw milk cheeses tend to have more vitamin B and C than pasteurized cheeses, and the diverse array of beneficial bacteria can contribute to improved gut health and a stronger immune system. Additionally, grass-fed raw milk cheese contains high amounts of naturally occurring Omega-3s and CLAs, which promote good heart health and enhanced brain function.
