The increasing popularity of vegetarian diets has sparked curiosity about the suitability of many staple foods and ingredients. Feta cheese, widely enjoyed for its tangy flavor and creamy texture, is one such product that raises questions among those following a vegetarian lifestyle. In this article, we examine whether feta cheese is vegetarian, which ingredients to look out for, and the considerations to keep in mind when including feta cheese in a vegetarian diet.
Short answer: Traditional or classic feta cheese is not vegetarian because it typically contains animal-derived rennet, used in the cheese-making process. The main ingredients in classic feta cheese include sheep’s milk (sometimes blended with goat’s milk), salt, cultures, and animal rennet.
Note: Some brands offer vegetarian-friendly feta made with microbial or plant-based rennet instead, but label-checking is essential since the use of animal rennet is common.
Understanding Vegetarianism in the Context of Food Products
For a product to be considered vegetarian, it must not contain any meat, poultry, fish, or byproducts derived from the slaughter of animals. Common non-vegetarian ingredients excluded are gelatin, animal rennet, animal fats, certain enzymes, isinglass (from fish), and some natural colorings like carmine (from insects). Most vegetarians do consume dairy and eggs, but only if no animal is harmed in the process.
Vegetarianism is both a dietary and ethical choice, aiming to reduce harm to animals. Many vegetarians extend their care beyond food, avoiding animal-based products in clothing and personal goods as well.
Ingredient Analysis: Basic Version of Feta Cheese
The classic version of feta cheese is not vegetarian due to the use of animal rennet, an enzyme extracted from the stomach lining of young calves or lambs, essential for cheese coagulation. Below is a summary of typical ingredients in traditional feta cheese:
| Ingredient | Origin |
|---|---|
| Sheep’s milk (sometimes with goat’s milk) | Animal (dairy) |
| Salt | Mineral |
| Cultures | Microbial |
| Animal rennet | Animal (not vegetarian) |
Product Variants and Their Ingredients
Some modern or store-bought feta cheeses substitute animal rennet with microbial or plant-based rennet, making them suitable for vegetarians. However, variations, flavored feta, and private-label products may still use animal rennet or add non-vegetarian ingredients like gelatin, lipase, or animal-based colorings.
Examples of non-vegetarian additions in variants include:
- Animal rennet (most common)
- Animal-sourced enzymes or lipase
- Gelatin (for enhanced texture, rare in feta but possible in spreads)
- Animal-based colorings (less common in feta)
Always check the ingredient list or look for “vegetarian rennet” or “suitable for vegetarians” labeling on the packaging.
Additional Considerations for Vegetarians
Controversial Ingredients
While the main concern with feta is rennet, some vegetarians are careful about other additives like colorings (e.g., carmine), coating agents (e.g., shellac), or even the type of salt (iodized with animal-derived anti-caking agents, though rare). In cheese, the focus is on rennet and enzymes. Microbial or plant-based rennet makes feta vegetarian-friendly, but such feta is often labeled as such.
Trace Amounts / Cross-Contamination
Products labeled “may contain traces of…” typically refer to allergen cross-contamination, such as nuts or soy, not animal products. These warnings are rarely a concern for vegetarians, though highly strict individuals may choose to avoid them out of caution for accidental inclusion of animal ingredients.
The Importance of Reading Labels
Ingredient lists are your best guide when determining if any feta cheese is vegetarian–particularly for international brands or local products, as recipes and rennet sources may vary over time and by location. Look for “vegetarian,” “suitable for vegetarians,” or “microbial/plant rennet” markings. Relying on habit can lead to mistakenly consuming animal-derived rennet, so vigilance is key.

Vegetarian Alternatives and Similar Products
Homemade Versions
Making feta-style cheese at home allows you to use guaranteed vegetarian rennet or cultures. Homemade cheese also lets you control salt, quality, and avoid additives, making it both a fun and secure option for vegetarians.
Other Available Vegetarian Products
- Certified vegetarian feta (look for brands using microbial or vegetable rennet)
- Other vegetarian cheeses (paneer, halloumi made with vegetarian rennet, ricotta)
- Cashew-based or tofu-based feta alternatives (plant-based vegan products)
- Homemade vegan “feta” from nuts or soy
Summary and Conscious Choice
In conclusion, classic feta cheese is not vegetarian due to its use of animal rennet. However, several brands now produce vegetarian-friendly feta using microbial or vegetable rennet—these are clearly labeled as such. Always read labels and ingredient lists, even on familiar brands, due to potential changes in sourcing or recipes.
As with all processed foods, feta cheese should be consumed in moderation, considering both dietary balance and ethical concerns. Making informed, conscious choices is essential—and, luckily, as demand for vegetarian products grows, so does the range of delicious and ethical options available!
