Kosher cheese is a dairy product that conforms to Jewish dietary regulations, known as kashrut. The laws of kashrut apply to food derived from living creatures and restrict the consumption of certain mammals, birds, and fish. For a food product to be considered kosher, it must meet several criteria, including permissible ingredients and proper slaughter. In the case of cheese, it must be made with kosher ingredients and equipment, and under continual, onsite rabbinic supervision. This is because cheese made by non-Jews without Jewish oversight is considered non-kosher, or gevinas akum. The presence of a mashgiach, or rabbinic supervisor, ensures that only kosher ingredients are used and that the production adheres to Jewish law.

Kosher cheese must be made under continual, onsite rabbinic supervision
According to Jewish law, or Halacha, a special prohibition makes kosher certification of cheese more challenging: the ban on gevinat akum, or "non-Jewish cheese". This means that cheese made by non-Jewish companies or individuals is not kosher. The Talmud states that the sages of the Mishnaic period forbade eating cheese manufactured by non-Jews. The reason for this prohibition is the use of rennet in cheesemaking. Since rennet was traditionally derived from the lining of a calf's stomach, Chazal (the Rabbinic Sages) forbade non-Jewish cheeses due to the likelihood that they contained rennet from calves that had not been slaughtered in accordance with Halacha.
Even a small amount of a non-kosher ingredient, such as animal rennet, can render the entire product non-kosher. Rennet is the enzyme that separates the milk's casein protein and fat and is a vital ingredient in traditional hard cheeses. Therefore, in the production of kosher cheese, a mashgiach (rabbinic supervisor) must often be present to supervise the process of adding rennet to the milk. This ensures that only kosher ingredients are used and that the production adheres to Jewish law.
In some cases, cheeses that are otherwise kosher but are not produced with the involvement of a mashgiach may not be certified as kosher. This is why it is important for consumers to look for reliable kosher certification symbols on cheese products.

Rennet, a vital ingredient in traditional hard cheeses, cannot be from non-kosher sources
For cheese to be kosher, it must meet the standards defined by Jewish scripture. This means that all the ingredients in the cheese, as well as the equipment used during the manufacturing process, must be kosher. However, there is a special rule in Jewish law that makes the kosher certification of cheese more challenging: cheese is only deemed kosher when made under continual, onsite rabbinic supervision. This is due to the concern that cheese could be made with non-kosher, animal-derived rennet.
Rennet is a vital ingredient in traditional hard cheeses. It is the enzyme that separates the milk's casein protein and fat. Rennet is traditionally derived from the abomasum (the fourth stomach section) of ruminants. In some countries, specific types of cheese are still produced from animal rennet, made from milled calf stomachs that are processed into a paste, powder, or liquid. However, today, most cheeses are made with microbial (synthetic) rennet rather than animal rennet.
As rennet is derived from animal stomachs, it cannot be used in kosher cheese unless it is from a kosher animal. Since it can’t be used, most kosher cheese is acid-set or made with microbial rennet. Kosher cheese manufacturers will naturally need to charge more for their products to cover the costs involved in onsite rabbinic supervision.
It is important to note that not all cheeses contain rennet. Some younger, softer cheeses like mozzarella, cottage cheese, cream cheese, and ricotta are often made without rennet. Additionally, microbial rennet is derived from the abomasum, so some people consider it non-vegetarian.

Kosher cheese must be made with milk from kosher animals
Kosher cheese is a type of cheese that conforms to Jewish dietary regulations, also known as kosher laws or kashrut. These laws are derived from the Torah and have been expanded upon through rabbinical teachings over the centuries. They dictate what foods are considered "fit" or "proper" for consumption according to Jewish tradition.
One of the key requirements for cheese to be considered kosher is that it must be made with milk from kosher animals. This means that the cheese can only be made from the milk of certain animals, such as cows, sheep, and goats, which are specifically permitted for use in meat or dairy products. Animals that are forbidden in kosher diets include pigs and shellfish, among others.
Additionally, the process of making kosher cheese must adhere to specific standards. This includes the use of kosher ingredients and equipment, as well as ongoing onsite supervision by a rabbi or a rabbinic supervisor (mashgiach) to ensure compliance with Jewish law. The rabbi's presence is particularly important during the addition of rennet, an enzyme derived from the stomachs of ruminants, to the milk. Traditional rennet is made from the abomasum (fourth stomach section) of calves, but modern kosher cheese often uses microbial or vegetarian rennet, which is not derived from animals.
The certification of kosher cheese can be challenging due to the prohibition of gevinat akum, or "non-Jewish cheese." This means that cheese made by non-Jewish companies or individuals without Jewish involvement or supervision is not considered kosher, even if the ingredients are all kosher. This prohibition is based on the concern that non-Jewish cheeses may contain non-kosher animal-derived rennet.
Overall, the process of making kosher cheese is highly regulated, and the involvement of a rabbi or rabbinic supervisor is crucial to ensure that the cheese meets the stringent requirements of Jewish dietary laws.

Kosher cheese cannot be mixed with meat
Kosher cheese is a dairy product that must adhere to strict rules and regulations outlined by Jewish scripture. One of the key principles of kosher food preparation is the separation of meat and dairy. This means that kosher cheese cannot be mixed with meat.
The Torah, the sacred text of Judaism, states, "Do not cook a kid in its mother's milk." This verse appears three times in the Torah, twice in Exodus (23:19 and 34:26) and once in Deuteronomy (14:21). According to Jewish tradition, this prohibition extends beyond simply cooking a young animal in its mother's milk. It is interpreted to mean that it is forbidden to cook, eat, or derive any benefit from a mixture of meat and milk.
The separation of meat and dairy in kosher food preparation extends beyond just the food itself. It is not permitted to cook dairy in a meat pot or meat in a dairy pot. Separate vessels must be used for meat and dairy, and care must be taken to ensure that steam from one does not blow onto the other during cooking. This separation even applies to cutlery and other culinary tools, which should not be used for both meat and dairy.
While kosher cheese cannot be mixed with meat, there are a variety of kosher-certified cheeses available. These cheeses are made with specific ingredients and processes that adhere to kosher requirements. Kosher cheese, for example, cannot contain natural rennet, which is derived from animals. Instead, most kosher cheese is acid-set or made with microbial rennet. Additionally, the production of kosher cheese must be overseen by a Rabbi who specializes in cheese, further contributing to the higher prices of kosher cheese compared to non-kosher cheese.

Kosher cheese must be certified with a symbol on the packaging
Kosher cheese must adhere to strict rules and requirements to be certified as such. The certification process involves a kosher certification agency checking the sources of all ingredients, verifying the kosher status of equipment, and setting up a system to monitor and maintain the integrity of both ingredients and equipment. This is because, according to Jewish scripture, cheese is only deemed kosher when made under continuous, onsite rabbinic supervision. This is due to the traditional use of non-kosher, animal-derived rennet in cheese-making.
The certification process is more than just a symbol on food packaging; it signifies a commitment to quality, compliance, and inclusivity. The symbol assures consumers that the contents meet the dietary laws of kashrut. The symbol is a valuable marketing tool, enhancing brand trust, visibility, and differentiation. It also broadens the customer base, appealing to vegetarians, vegans, and those with dietary restrictions or food allergies.
Once a company is successfully certified, they receive a letter of certification, which can be placed on their website, and a trademarked kosher logo to be displayed on their packaging. The most common kosher certification symbol is the circle U, but other widely recognized symbols include "OU" and "OK".
Therefore, the symbol on the packaging is a crucial aspect of kosher certification, providing consumers with the reassurance that the product has been vetted and approved by a kosher certifying agency.
