Whether or not cheddar cheese is vegetarian depends on the type of vegetarianism one follows. Most vegetarians avoid products that require the slaughter of animals, and since cheesemaking does not require this practice, many vegetarians include cheese in their diet. However, some cheeses are made using animal byproducts for texture and taste, such as rennet, which is derived from the stomach lining of slaughtered calves, cows, goats, sheep, and even pigs. Traditional cheddar cheese is made with animal-derived rennet, but some varieties are now produced using microbial or vegetable rennet, making them vegetarian-friendly.

Rennet: a common animal byproduct used in cheesemaking
Rennet is a common animal byproduct used in cheesemaking. It is a combination of enzymes that work together to thicken dairy-based milk and separate it into curds and whey. The enzymes that make up rennet are typically derived from the stomach lining of animals, including cows, rabbits, pigs, and goats. In particular, calves, as they are often killed for veal. However, rennet can also be produced without the use of animals through a fermentation process that mixes bacteria, fungi, or yeasts with rennet-producing animal genes to create an enzyme that acts like chymosin.
While animal rennet is not vegetarian, it is found in a lot of cheese, even from artisan dairies. Cheesemakers are not required to specifically label the use of animal rennet in the United States, making it difficult for consumers to make informed choices. This lack of transparency in labelling practices can be frustrating for vegetarians and those with specific dietary restrictions. Some cheesemakers choose to disclose the use of plant-based rennet, listing it as thistle rennet, vegetarian rennet, or plant rennet. However, without clear labelling regulations, consumers must often rely on independent research or seek advice from knowledgeable sources.
The inclusion of animal rennet in cheese poses a dilemma for vegetarians, who generally strive to avoid consuming specific animal products and byproducts. The consumption of cheese, particularly those containing animal rennet, is a matter of personal choice and belief within the vegetarian community. Some vegetarians may choose to avoid cheese altogether, while others may opt for vegetarian-friendly alternatives, such as cheeses made with vegetable rennet derived from thistle plants or microbial rennet derived from fungus, yeast, or mold. These alternatives are gaining popularity and can be found in health food stores or specialty brands.
Cheddar cheese, a popular variety, has traditionally been made with animal-derived rennet, but many producers are now shifting towards using microbial or vegetable rennet to cater to vegetarian consumers. This shift highlights the increasing demand for vegetarian options and the recognition of diverse dietary preferences. When purchasing cheddar cheese, it is essential to read the labels carefully. Look for labels that explicitly state the use of non-animal rennet or seek out certified kosher cheeses, as Jewish religious laws prohibit the mixing of milk and meat, ensuring the absence of animal rennet.

Animal rennet: not vegetarian-friendly
Whether or not cheddar cheese is vegetarian-friendly depends on the type of vegetarianism followed. While some vegetarians are less strict, stricter vegetarians and vegans avoid animal products or byproducts, including dairy and milk.
Animal rennet is not vegetarian-friendly. It is derived from the stomach lining of slaughtered calves, cows, goats, sheep, and even pigs. This enzyme is commonly used in cheesemaking to help milk separate into curds and whey. However, it is not always clearly labelled, and cheesemakers are not required to specify its use in the United States.
To avoid animal rennet, look for labels that explicitly state the cheese is made with non-animal rennet. Keywords to look out for include "vegetarian rennet" or "plant rennet", which is often sourced from thistle plants. Certified kosher cheeses are also a safe option, as they will not contain animal rennet according to Jewish religious laws.
While traditional cheddar cheese is made with animal-derived rennet, many varieties now use microbial or vegetable rennet, making them vegetarian-friendly. When in doubt, it is best to research or ask a knowledgeable cheesemonger about the source of the rennet used.

Vegetable rennet: a vegetarian-friendly option
Whether or not a cheese is vegetarian-friendly depends on the type of vegetarianism followed. Lacto- and lacto-ovo-vegetarians, for example, are comfortable consuming dairy products, whereas vegans avoid all animal products and by-products, including dairy.
Some cheeses are made using animal by-products, such as rennet, for texture and taste. Rennet is a combination of enzymes that work together to thicken dairy-based milk. The most common type of rennet is derived from the stomach lining of animals, including cows, rabbits, pigs, and goats. However, animal rennet is not always used in cheesemaking.
Vegetable rennet is a vegetarian-friendly option. It is made via a fermentation process in which bacteria, fungi, or yeasts are mixed with rennet-producing animal genes to create an enzyme that acts like chymosin, which is the enzyme that curdles the milk during cheese production. Thistle plants, such as artichokes or nettles, are often used to create vegetable rennet, and it is commonly found in artisanal cheeses from Portugal.
When looking for vegetarian-friendly cheese, it is important to read the label. If the cheese is made with vegetable rennet, it will typically be listed as thistle rennet, vegetarian rennet, or plant rennet. However, in some places, such as the US, cheesemakers are not required to disclose which type of rennet they use. In these cases, if the packaging only reads "enzymes" and does not state that the product is vegetarian-friendly, it is safe to assume that animal rennet was used.

Kosher-certified cheeses: do not contain animal rennet
Cheddar cheese may not always be vegetarian. This is because, traditionally, animal rennet was used in the production of cheese. Rennet is a crucial element in the cheese-making process, as it causes milk to curdle and separate into solid curds and liquid whey. Animal rennet is derived from the stomach lining of ruminants, such as calves, and is considered a crucial part of producing "hard cheeses" like cheddar.
In recent times, microbial (synthetic) rennet has become a more common alternative to animal rennet, making many modern cheeses suitable for vegetarians. However, it is important to read the labels when purchasing cheese, as the source of rennet may not always be clearly indicated. Some manufacturers may simply list “enzymes” as an ingredient, requiring further investigation to determine if the product is vegetarian-friendly.
To ensure that cheddar cheese is vegetarian, it is advisable to look for specific labels indicating the use of microbial or vegetarian rennet. Some brands, such as Tillamook, are known for offering a range of vegetarian cheeses. Health food stores and organic grocery stores are also more likely to stock vegetarian cheese options.
Now, regarding your request for information about Kosher-certified cheeses, it is important to understand the role of rennet in this context. According to Jewish Law, kosher certification for cheese presents a unique challenge. The concern arises from the traditional use of non-kosher, animal-derived rennet in cheese production. To address this, kosher certification for cheese requires continual onsite rabbinic supervision during the cheese-making process. This ensures that only kosher-approved rennet is used and that no animal-derived rennet is present in the final product.
Therefore, when purchasing Kosher-certified cheeses, you can be confident that they do not contain animal rennet. The presence of a rabbinic coordinator, such as Rabbi Avrohom Gordimer of OU Kosher, further ensures that the cheese adheres to the strict requirements of kashrut (Jewish dietary laws). By seeking out Kosher-certified cheeses, you can rest assured that they meet the necessary standards and do not contain any animal-derived ingredients, including animal rennet.

Different types of vegetarians: some may avoid cheese altogether
Vegetarianism can take many forms, and some types of vegetarians may choose to avoid cheese altogether. The most common type of vegetarianism is the lacto-ovo-vegetarian diet, which includes dairy products and eggs but excludes all meats, including fish, chicken, pork, and beef. However, some cheeses are made using animal rennet, which comes from the stomach lining of young calves, making them unsuitable for vegetarians. While some vegetarians may unknowingly consume cheese with animal rennet, others may choose to avoid cheese altogether to ensure they do not consume any animal products.
Another type of vegetarian diet is the ovo-vegetarian diet, which includes eggs but excludes all dairy products, including cheese, as well as meat and fish. Ovo-vegetarians may choose to avoid cheese altogether due to the presence of animal rennet in some varieties. They may also opt for vegan cheese, which is guaranteed to be free of animal products.
Lacto-vegetarians, on the other hand, follow a plant-based diet that includes dairy products but excludes all meats, eggs, and animal products. While lacto-vegetarians may consume cheese, they may encounter challenges due to the prevalence of animal rennet in many traditional cheese varieties. Some lacto-vegetarians may opt to avoid cheese altogether, especially if they are unsure about the ingredients or sourcing of the cheese.
Flexitarians, or those following a flexible vegetarian diet, may also choose to avoid cheese. Flexitarians emphasize plant-based foods while allowing small amounts of animal products in moderation. They may opt for vegan or vegetarian cheese options or choose to forgo cheese altogether, depending on their personal preferences and level of flexibility.
The availability of vegetarian cheese options also varies by region. For example, in European markets, most cheeses are not vegetarian, and finding vegetarian alternatives can be challenging. In such cases, some vegetarians may choose to avoid cheese altogether or seek out specialty health food stores that offer vegetarian or vegan cheese options.
In summary, while some vegetarians may choose to include cheese in their diets, others may opt to avoid it altogether due to the presence of animal rennet in many varieties. The decision to avoid cheese depends on the individual's specific dietary restrictions, personal preferences, and the availability of vegetarian cheese options in their region.
