Gorgonzola cheese, with its distinctive blue veins and pungent aroma, is a culinary delight enjoyed worldwide. Its creamy texture and sharp flavor make it a versatile ingredient in everything from salads to pasta dishes. However, for vegetarians, the question of whether Gorgonzola fits into their diet is a common one. Understanding the cheesemaking process, specifically the use of animal rennet, is crucial to answering this question. Let’s delve into the intricacies of Gorgonzola production and its suitability for vegetarians.
Understanding Gorgonzola Cheese
Gorgonzola is a blue cheese originating from Italy, specifically the town of Gorgonzola near Milan. It’s made from unskimmed cow’s milk and is characterized by its blue-green veins caused by the introduction of Penicillium mold during the cheesemaking process. These molds contribute significantly to the cheese’s unique flavor profile.
The Cheesemaking Process: A Detailed Look
The production of Gorgonzola involves several key steps. First, fresh cow’s milk is pasteurized or, in some cases, used raw. A starter culture, containing beneficial bacteria, is added to acidify the milk and begin the coagulation process. This acidification is vital for the development of the cheese’s characteristic flavor.
Next, rennet is added to coagulate the milk, forming a solid curd. This is where the key question for vegetarians arises, as traditional rennet is derived from animal sources.
The curd is then cut into small pieces to release whey, the liquid portion of the milk. After draining the whey, the curds are placed into molds. Penicillium spores, which give Gorgonzola its distinctive blue veins, are introduced at this stage, either by adding them to the milk or directly into the curd.
The cheese is then salted and aged in a cool, humid environment for a minimum of 50 days, and often for several months. During this aging process, the Penicillium mold grows and spreads, creating the characteristic blue veins and contributing to the cheese’s complex flavor. To facilitate the mold growth, the cheeses are pierced with needles to allow air to circulate.
The Role of Rennet in Cheesemaking
Rennet is an enzyme used to coagulate milk, separating it into solid curds and liquid whey. This is a crucial step in cheesemaking, as it allows the cheese to develop its solid form. Traditionally, rennet is extracted from the lining of the stomachs of unweaned calves. This type of rennet contains enzymes, primarily chymosin, that effectively coagulate milk.
However, animal rennet is not the only option available. There are several vegetarian alternatives, including microbial rennet, vegetable rennet, and fermentation-produced chymosin (FPC). Microbial rennet is derived from fungi or bacteria. Vegetable rennet is extracted from plants, such as thistles or nettles. FPC is produced by genetically modified microorganisms and is considered a vegetarian-friendly option because it doesn’t involve animals in its production.
Gorgonzola and Vegetarianism: The Crucial Question of Rennet
Whether Gorgonzola cheese is suitable for vegetarians hinges on the type of rennet used in its production. If animal rennet is used, the cheese is not considered vegetarian. However, if a vegetarian alternative like microbial rennet, vegetable rennet, or FPC is used, then the Gorgonzola is suitable for vegetarians.
Identifying Vegetarian-Friendly Gorgonzola
Unfortunately, it’s not always easy to determine the type of rennet used in a specific Gorgonzola cheese. Manufacturers are not always required to specify the source of rennet on the product label.
The best way to ensure that a Gorgonzola cheese is vegetarian is to look for specific labeling indicating that it is made with vegetarian rennet. Look for terms like “vegetarian rennet,” “microbial rennet,” or “vegetable rennet” on the packaging.
If the packaging doesn’t specify the type of rennet, contacting the manufacturer directly is the most reliable way to find out. They should be able to provide information about their cheesemaking process and the type of rennet used.
The Prevalence of Animal Rennet in Gorgonzola Production
Historically, animal rennet was the most common type used in Gorgonzola production. While vegetarian alternatives are becoming more widely available, many traditional cheesemakers still use animal rennet to produce Gorgonzola. This is often due to tradition, perceived differences in flavor or texture, or simply cost considerations.
Vegetarian Certifications
Looking for vegetarian certifications on the packaging can also be helpful. Products certified by vegetarian organizations have been vetted to ensure they meet specific vegetarian standards, including the use of vegetarian rennet.
The Flavor and Texture of Gorgonzola Made with Vegetarian Rennet
Some people believe that the type of rennet used can affect the flavor and texture of cheese. However, in the case of Gorgonzola, it’s difficult to discern a significant difference between cheese made with animal rennet and cheese made with vegetarian rennet, especially by the average consumer. The Penicillium mold, the milk quality, and the aging process have a far greater impact on the final product’s flavor and texture.
The flavor of Gorgonzola, regardless of the rennet used, is typically described as sharp, pungent, and slightly salty. The texture is creamy and crumbly, with a melt-in-your-mouth quality.
The aging process also plays a crucial role. Younger Gorgonzola is typically milder and creamier, while aged Gorgonzola becomes more intense and flavorful.
Cooking with Vegetarian-Friendly Gorgonzola
Vegetarian Gorgonzola can be used in all the same ways as traditional Gorgonzola. It’s a delicious addition to salads, pizzas, pasta dishes, and cheese boards. Its strong flavor pairs well with sweet ingredients like pears, figs, and honey. It also works well in savory dishes, adding a rich, creamy element to sauces and dressings.
Here are a few serving suggestions:
- Crumble it over a salad of mixed greens, walnuts, and pears.
- Spread it on crusty bread with a drizzle of honey.
- Melt it into a creamy pasta sauce.
- Add it to a pizza with caramelized onions and roasted vegetables.
- Serve it on a cheese board with crackers, fruit, and nuts.
Navigating the World of Vegetarian Cheese
The question of whether a cheese is vegetarian often comes down to understanding the ingredients and the cheesemaking process. With increasing awareness and demand for vegetarian options, many cheese producers are now offering vegetarian-friendly versions of popular cheeses.

Frequently Asked Question 1: What is Gorgonzola cheese and what makes it unique?
Gorgonzola is a veined Italian blue cheese made from unskimmed cow’s milk. Its distinctive flavor profile, ranging from creamy and mild to sharp and pungent, is a result of the Penicillium mold cultures intentionally introduced during the cheese-making process. These cultures also give Gorgonzola its characteristic blue-green marbling, differentiating it from other blue cheeses like Stilton or Roquefort.
This cheese is traditionally aged for a minimum of three months, allowing the mold to develop and the flavors to intensify. The aging process takes place in cold, humid caves, creating an environment conducive to the growth of Penicillium and contributing to the cheese’s unique texture and taste. It’s a Protected Designation of Origin (PDO) cheese, meaning it can only be produced in specific regions of Italy using traditional methods.
Frequently Asked Question 2: Why is rennet a concern for vegetarians when considering cheese?
Rennet is an enzyme used in cheesemaking to coagulate milk, separating the curds from the whey. Traditional rennet is derived from the stomach lining of unweaned calves, making it an animal product and therefore unsuitable for vegetarians. This is the primary reason why many cheeses, including some Gorgonzola, are not considered vegetarian-friendly.
However, vegetarian alternatives to animal rennet exist. These alternatives include microbial rennet (produced by fungi or bacteria), vegetable rennet (derived from plants), and genetically engineered rennet (FPC – fermentation-produced chymosin). The source of rennet is crucial information for vegetarians seeking to avoid animal-derived ingredients.
Frequently Asked Question 3: Is all Gorgonzola cheese made with animal rennet?
No, not all Gorgonzola cheese is made with animal rennet. While traditional Gorgonzola recipes often utilize animal rennet, many modern producers are now using vegetarian rennet alternatives. The use of vegetarian rennet allows them to cater to a wider consumer base, including vegetarians and those seeking to reduce their consumption of animal products.
It is important to note, however, that labeling practices can vary. While some producers clearly label their Gorgonzola as using vegetarian rennet, others may not. This necessitates careful investigation on the part of the consumer to determine the source of rennet used in a specific product.
