If you are a vegetarian who loves a great cheese board, you might have experienced a moment of panic upon hearing a surprising rumour: not all cheese is vegetarian. It sounds counterintuitive — cheese is made from milk, a dairy product, so it should automatically be vegetarian-friendly, right?
The catch lies in a traditional, behind-the-scenes ingredient used in the cheesemaking process called rennet. Here is everything you need to know about rennet, how to spot vegetarian-friendly cheeses, and why you never have to compromise on gourmet flavour.
What Exactly is Rennet?
To turn liquid milk into delicious, solid cheese, cheesemakers need an enzyme to help the milk proteins coagulate — clump together and separate into curds and whey. Historically, this enzyme — rennet — was extracted from the stomach lining of calves.
Because traditional animal rennet is a byproduct of the meat industry, cheeses made using this method are strictly off-limits for vegetarians. Classic European cheeses with protected status, like authentic Parmigiano-Reggiano or traditional Roquefort, are legally required to use animal rennet to maintain their namesake — making them non-vegetarian by definition.
The Rise of 100% Vegetarian Cheese
Fortunately, modern artisanal cheesemaking has evolved. Today, there are excellent, high-quality alternatives to animal rennet that produce the exact same gourmet textures and complex flavour profiles:
- Microbial Rennet: Produced using enzymes from fungi or bacteria. Widely used in the artisanal cheese world today and 100% vegetarian.
- Plant-Based Rennet: Some traditional cheesemakers use natural coagulants derived from plants, such as thistle, fig tree bark, or nettles — a centuries-old practice in parts of Europe.
- Fermentation-Produced Chymosin (FPC): A highly purified rennet produced through fermentation — the most widely used vegetarian rennet in modern cheesemaking.
Which Cheeses Are Usually Vegetarian-Safe?
While you should always check the label or ask your cheesemonger, certain styles of cheese are almost always vegetarian by nature:
- Fresh, unaged cheeses rely more on acidity (like lemon juice or vinegar) and bacterial cultures to curdle the milk, requiring little to no rennet at all.
- Fresh Mozzarella — a milky, soft cheese that uses minimal rennet and is typically vegetarian-friendly.
- Mascarpone — made by curdling cream with an acid, requiring no rennet at all.
- Cream Cheese — similarly acid-set, making it a safe and delicious vegetarian staple.
- Ricotta — traditionally made from whey with heat and acid, no rennet required.
On the other hand, always double-check hard aged cheeses like Parmesan, Pecorino, Manchego, and Gruyère — their traditional versions often use animal rennet.
How to Spot Vegetarian Cheese on a Label
When shopping for cheese, look for these indicators:
- ✅ “Vegetarian rennet” or “microbial rennet” listed in the ingredients
- ✅ A Vegetarian Society approved logo or similar certification
- ✅ The word “suitable for vegetarians” on the packaging
- ❌ Avoid cheeses listing “animal rennet” or simply “rennet” without clarification
When in doubt, ask! A good cheesemonger or artisan producer will always be happy to tell you exactly what goes into their cheese.
