What cheeses use animal rennet?

Answered by Michael Blake

As a sommelier and brewer, I have had the opportunity to explore the world of cheese and the varied techniques used in its production. One aspect that often comes up is the use of animal rennet in certain types of cheese. Rennet is an enzyme traditionally derived from the stomach lining of young ruminant animals, such as calves or lambs. It plays a crucial role in the coagulation of milk, which is a key step in cheese making.

Many beloved and popular hard cheeses, such as Parmesan, Cheddar, Manchego, Pecorino Romano, and Swiss, have historically been made with animal rennet. These cheeses have distinct flavors and textures that are greatly influenced by the use of rennet in their production. The enzymes in rennet help break down the milk proteins, allowing the curds to form and develop into the cheese we know and love.

However, in recent years, there has been a growing demand for vegetarian-friendly and vegan options, leading to the development of cheeses made with non-animal-derived enzymes. This has allowed more people to enjoy the flavors and textures of cheese without compromising their dietary preferences.

While many cheeses still use animal rennet, there are now alternatives available for those who prefer to avoid it. Here are five examples of cheeses that are commonly made without animal rennet:

1. Ricotta: This soft and creamy cheese is typically made from the whey leftover from other cheese production. It is often made using vinegar or lemon as a coagulant, eliminating the need for rennet.

2. Paneer: A popular cheese in Indian cuisine, paneer is made by curdling milk with lemon juice or vinegar. It has a mild, milky flavor and a firm, crumbly texture.

3. Mozzarella: While traditional mozzarella is made with animal rennet, there are now vegetarian versions available that use microbial or vegetable-based rennet. These alternatives still produce the characteristic stretchy texture and mild flavor of mozzarella.

4. Goat cheese: Many goat cheeses, such as fresh chevre or feta, are made without rennet. They often rely on acidification or other non-animal coagulants to achieve their unique tangy flavors and creamy textures.

5. Blue cheese: Some blue cheeses, like Gorgonzola or Roquefort, can be made with non-animal-derived enzymes. These cheeses undergo a specific aging and inoculation process that allows the blue mold to develop and create the signature pungent flavors, even without animal rennet.

It's worth noting that the availability of cheeses made without animal rennet can vary depending on where you live and the specific cheese producers in your area. However, with the increasing demand for vegetarian and vegan options, more and more cheese makers are exploring alternative coagulants to cater to a wider range of dietary preferences.

As a lover of cheese myself, I find it fascinating to see how the industry is evolving and adapting to meet the needs and desires of consumers. Whether you choose to enjoy cheeses made with traditional animal rennet or opt for vegetarian-friendly alternatives, there is a wide world of flavors and textures to explore.
