Rennet: The Key Ingredient in Cheese Making

Rennet in cheese: What is it, and why does it matter? Learn about this key ingredient and find out which cheeses are safe for vegetarians and alpha gals.

Rennet coagulates milk into curds and whey. It is essential for diverse cheese textures and flavors. Luckily, there are mammal-free options available.

Animal rennet, used in traditional cheese recipes, can trigger alpha-gal symptoms because it's made from the stomach lining of young ruminants.

Plant-based rennet offers a vegetarian alternative in cheesemaking, thickening milk just like animal rennet.

Microbial rennet is another vegetarian-friendly coagulant, but may add a bitter taste, especially in aged cheeses.

Traditional Parmesan, a staple in Italian cuisine, is never vegetarian as it adheres to strict guidelines that include the use of animal rennet.

But younger, softer cheeses can be produced with vinegar or lemon juice instead of animal rennet. As a result, cream cheese, ricotta, chevre, fresh mozzarella, and provolone are generally considered safe for vegetarians.
