Understanding the 'Is Cheese Vegetarian' Conundrum
For many vegetarians, particularly those who are lacto-ovo or lacto-vegetarians, cheese is a staple food. However, the question of whether all cheese is truly vegetarian is a valid and important one. The answer lies in a single, often overlooked ingredient: rennet.
The Role of Rennet in Cheesemaking
Rennet is a complex set of enzymes used to curdle milk, separating the solid curds from the liquid whey during the cheesemaking process. Without a coagulant like rennet, making many types of hard and semi-hard cheeses would not be possible.
Historically, rennet was sourced from the fourth stomach lining of young ruminant animals, such as calves, lambs, or goats. Because this traditional animal rennet is an animal byproduct obtained from the slaughter of these animals, it is not suitable for most vegetarians.
The Rise of Vegetarian Rennet
Fortunately, for vegetarians who still wish to enjoy cheese, several non-animal alternatives are now widely used. These include:
- Microbial Rennet: Produced by fermenting certain fungi or molds, this is the most common vegetarian alternative used in modern cheese production.
- Vegetable Rennet: Derived from plants like thistle, fig leaves, or nettles, this is a less common but still viable option, often found in specialty cheeses.
- Fermentation-Produced Chymosin (FPC): This type uses genetically engineered microorganisms to produce chymosin, the key enzyme found in animal rennet, without using any animal-based genetic material in the final product. It is widely used and considered vegetarian.
How to Identify Vegetarian-Friendly Cheese
The simplest and most effective way to ensure your cheese is vegetarian is to read the ingredient list and product label carefully.
What to Look for on Labels
- Explicit Labeling: The easiest route is to look for phrases like "suitable for vegetarians," or for a certified V-label or vegetarian society logo.
- Ingredient Check: If explicit labeling isn't present, check the ingredients. Vegetarian-friendly cheese will list "microbial enzymes," "vegetable rennet," or "fermentation-produced chymosin".
- Avoid Certain Terms: If the label simply says "enzymes" or "rennet" without specifying the source, or lists "animal enzymes," it is not vegetarian. Some kosher cheeses are also guaranteed to be vegetarian, as Jewish dietary laws prohibit mixing meat and dairy.
Cheeses to Be Wary Of
Some traditional and aged cheeses, particularly those with a protected designation of origin (PDO) status in Europe, are legally required to use animal rennet. These are almost never vegetarian and should be avoided unless a specific vegetarian version is explicitly labeled.
- Cheeses traditionally made with animal rennet:
- Parmigiano Reggiano (true Parmesan)
- Manchego
- Grana Padano
- Gruyère
- Gorgonzola
It's important to note that many supermarkets and commercial brands produce their own versions of these cheeses using microbial rennet, but the traditional, imported products are not vegetarian.
The Best Bet: Acid-Coagulated Cheeses
Some soft, fresh cheeses do not use rennet at all, relying instead on an acid like lemon juice or vinegar to coagulate the milk. These are almost always vegetarian and include:
- Paneer: A fresh, soft Indian cheese
- Ricotta: Italian whey cheese
- Cream Cheese: A soft, mild, fresh cheese
- Cottage Cheese: Fresh curds and whey
- Fresh Mozzarella: The softer, fresh variety
The Rise of Vegan Cheese
For those who wish to avoid all dairy, including milk, vegan cheese alternatives are a growing market. These products are made entirely from plant-based ingredients and are completely free from animal products.
Common ingredients in vegan cheese:
- Nuts (cashews, almonds)
- Soy protein
- Vegetable oils (coconut oil)
- Nutritional yeast for a cheesy flavor
Vegetarian vs. Vegan Cheese: A Comparison Table
| Feature | Vegetarian Cheese | Vegan Cheese |
|---|---|---|
| Dairy Content | Contains milk from animals (cow, goat, sheep). | Contains no milk or dairy products. |
| Rennet Type | Uses non-animal rennet (microbial, vegetable, FPC). | Uses no rennet, as it contains no dairy to coagulate. |
| Base Ingredients | Animal milk, salt, vegetarian rennet, cultures. | Plant-based ingredients like nuts, soy, vegetable oils, and starches. |
| Dietary Suitability | Suitable for lacto-vegetarians and lacto-ovo vegetarians. | Suitable for vegans and individuals with lactose intolerance or dairy allergies. |
| Texture and Flavor | Often identical to traditional cheese made with animal rennet. | Varies widely depending on the base; advancements have improved texture and meltability significantly. |
Navigating Your Cheese Options
Choosing vegetarian cheese is straightforward once you know what to look for on the label. Many popular and widely available brands offer vegetarian-friendly options. Some examples include:
- Tillamook: Uses fermentation-produced rennet for most products.
- Cabot: Known for many vegetarian cheddar options.
- Organic Valley: Offers a range of vegetarian cheese choices.
- Trader Joe's & Whole Foods 365: Many of their store-brand cheeses use microbial rennet.
- BelGioioso: Sells a vegetarian Parmesan style cheese.
For more artisanal or foreign cheeses, a visit to a dedicated cheese shop where you can speak to a cheesemonger is a great way to confirm the rennet source.
In conclusion, can you eat cheese as a vegetarian? Yes, you can, but with careful label-reading to ensure no animal rennet was used. With the vast availability of vegetarian and vegan cheese options today, enjoying a dairy-based diet without compromising your principles has never been easier.

Final Recommendations for a Vegetarian Cheese Diet
Ultimately, a vegetarian can eat cheese, but it requires being an informed consumer. Always check the ingredient list for the specific type of rennet used. If you are unsure, opt for soft, acid-coagulated cheeses or seek out brands that explicitly label their products as vegetarian-friendly. The good news is that with the rise in demand for vegetarian options, most major commercial cheese products now use non-animal rennet, making it easier than ever to find delicious cheese that aligns with your dietary choices.
