Blue cheese is made with the addition of cultures of edible moulds, which create blue-green spots or veins through the cheese. Blue cheese is believed to have been discovered by accident when cheeses were stored in caves with naturally controlled temperature and moisture levels, which happened to be favourable environments for various harmless moulds. Blue cheese is typically aged in temperature-controlled environments. Blue-veined cheese may contain more healthy bacteria than a straight-up firm cheese, but those who are immune-compromised should avoid it. Blue cheese is made with the addition of a freeze-dried Penicillium roqueforti culture. All milk products contain casein, a type of protein with a substantial amount of amino acids that is easily digestible by the human body. However, some people are allergic to casein and should avoid cheese or opt for vegan, lactose-free, or nut-based cheese alternatives. So, does blue cheese contain A1 casein?

What You'll Learn
Blue cheese is made with edible mould cultures
Multiple methods can be used to culture the mould, but all involve the use of freeze-dried Penicillium roqueforti. This mould is then added to autoclaved, homogenized milk via a sterile solution, along with salt and/or sugar. The mixture is incubated for three to four days at 21–25 °C (70–77 °F). More salt and/or sugar is added, and aerobic incubation is continued for an additional one to two days.
Alternatively, sterilized, homogenized milk and reconstituted non-fat solids or whey solids are mixed with sterile salt to create a fermentation medium. A spore-rich Penicillium roqueforti culture is then added. Next, modified milk fat is added, which consists of milk fat with calf pre-gastric esterase. This stimulates the release of free fatty acids, which is essential for the rapid flavour development of blue cheese.
Once the cheese is freshly made, it has little to no blue cheese flavour. To develop this flavour, the cheese is punctured to create small openings to allow air to penetrate and support the growth of the mould cultures, thus encouraging the formation of blue veins. The cheese is then aged for 60–90 days, during which time the temperature and humidity are carefully monitored to ensure the cheese does not spoil and maintains its optimal flavour and texture.

Blue cheese is believed to have been discovered by accident
The key to blue cheese's unique characteristics lies in a specific type of mould, Penicillium roqueforti, which breaks down the cheese's proteins and fats. This mould is responsible for the blue-green veins that give blue cheese its name. The process of making blue cheese involves adding Penicillium roqueforti to the cheese, either by injection or by allowing it to develop naturally during ageing. The cheese is then aged in a cool, humid environment, allowing the mould to grow and enhance its flavour and appearance.
The ancient civilizations that first discovered blue cheese through this accidental process laid the foundation for its culinary journey. Blue cheese found its way to various regions, including France, where it became a delicacy in the areas of Roquefort and Gorgonzola. In England, Stilton cheese emerged as a national treasure, while Gorgonzola and Castelmagno gained popularity in Italy. Each region has developed its unique interpretations and variations of this culinary masterpiece.
The versatility of blue cheese extends beyond its solo enjoyment. It pairs beautifully with sweet fruits like pears and apples, as well as nutty accompaniments such as walnuts and almonds. Blue cheese also lends its distinctive flavour to a variety of dishes, including salads, pasta, and even desserts. Its bold presence adds intrigue to creamy sauces, and its crumbly texture provides a delightful contrast in baked goods.
The accidental discovery of blue cheese has undoubtedly left a lasting impact on the culinary world, with its unique flavour profile, texture, and versatility. From ancient civilizations to modern-day kitchens, blue cheese continues to inspire chefs and home cooks alike, securing its place as a treasured ingredient for generations to come.

Blue cheese is aged in temperature-controlled environments
Blue cheese is believed to have been discovered by accident when cheeses were stored in caves with naturally controlled temperatures and moisture levels, which turned out to be favourable environments for the growth of harmless mould. Today, blue cheeses are typically aged in temperature-controlled environments.
Blue cheese is any cheese made with the addition of cultures of edible moulds, which create blue-green spots or veins through the cheese. Blue cheese is made in a similar way to other varieties of cheese, but additional ingredients and processes are required to give it its distinctive properties.
The first phase of production involves preparing a Penicillium roqueforti inoculum. This is done by washing the Penicillium roqueforti from a pure culture agar plate, which is then frozen. Through freeze-drying, water is evaporated from the frozen state without transitioning to the liquid state (a process known as sublimation). This retains the value of the culture, which is activated when water is added.
Salt, sugar, or both are then added to autoclaved, homogenized milk via a sterile solution. This mixture is then inoculated with Penicillium roqueforti and incubated for three to four days at 21–25 °C (70–77 °F). More salt and/or sugar is added, and then aerobic incubation is continued for an additional one to two days.
The next step is coagulation, where rennet, a mixture of rennin and other material found in the stomach lining of a calf, is added to further solidify the milk. The curds are then cut into small pieces to encourage the release of liquid or whey. The smaller the curds are cut, the thicker and harder the resulting cheese will be. After being ladled into containers to drain, the curds are formed into a full wheel of cheese, and the Penicillium roqueforti inoculum is sprinkled on top, along with Brevibacterium linens. The curds are then knit into moulds to form cheese loaves with a relatively open texture.
Whey drainage continues for 10–48 hours, with the moulds being inverted frequently to promote this process. Salt is then added to provide flavour and act as a preservative so that the cheese does not spoil. This process of brine salting or dry salting takes 24–48 hours.
Blue cheeses vary in flavour, colour, and consistency. They may have a distinctive smell, either from the mould or from various specially cultivated bacteria such as Brevibacterium linens. Some blue cheeses are injected with spores before the curds form, while others have spores mixed in with the curds after they form.
It is worth noting that casein, a type of protein found in all milk products, is present in cheese. Blue-veined cheese likely contains more healthy bacteria than firm cheeses, but those with compromised immune systems may want to avoid them. If you have a casein allergy, it is recommended to try vegan cheese options, although some of these do contain soy and coconut.

Blue cheese contains more healthy bacteria than firm cheeses
Blue cheese is a type of cheese that contains blue veins or marbling and is made using a type of mould called Penicillium roqueforti. It is a nutrient-dense food, containing high levels of calcium, vitamins, minerals, and natural compounds that are beneficial to health.
Blue cheese is a good source of healthy bacteria, which can be linked to anti-inflammatory effects and improved gut health. Dr Megan Rossi, @theguthealthdoctor on Instagram, explains that blue cheese contains penicillium fungi, which are the blue veins running through the cheese. These fungi are nontoxic and safe for human consumption.
Michael Jones, a cheesemonger and owner of The Cheeseboard in London, recommends including blue cheese on your cheeseboard to "diversify your gut health and introduce healthy bacteria in a very tasty way." He suggests that the quality of the milk and the ageing of the cheese add to the health benefits of eating blue cheese.
Blue cheese contains a compound called spermidine, which may delay ageing and reduce the risk of cardiovascular disease. It is also a great source of protein. However, it is important to consume blue cheese in moderation due to its high-fat content, particularly saturated fat, as well as its high calorie and sodium content.
While blue cheese contains healthy bacteria and offers various health benefits, it is a dairy product and therefore contains casein. Casein is a type of protein found in all milk products, and some people may have an allergy or intolerance to it. If you are avoiding casein, it is recommended to try vegan cheese options or casein-free cheese made from nuts.

Blue cheese can cause allergic reactions
Blue cheese is any cheese made with the addition of cultures of edible moulds, which create blue-green spots or veins through the cheese. Blue cheese is believed to have been discovered by accident when cheeses were stored in caves with naturally controlled temperature and moisture levels, which happened to be favourable environments for various harmless moulds.
The process of making blue cheese consists of six standard steps. However, additional ingredients and processes are required to give this blue-veined cheese its particular properties. To begin with, the commercial-scale production of blue cheese consists of two phases: the culturing of suitable spore-rich inocula and fermentation for maximum, typical flavour. In the first phase of production, a Penicillium roqueforti inoculum is prepared prior to the actual production of blue cheese.
Some blue cheeses are injected with spores before the curds form, and others have spores mixed in with the curds after they form. Blue cheeses are typically aged in temperature-controlled environments. If you are allergic to casein, it is recommended that you try vegan cheese options. However, if you have food allergies, be warned that some selections do contain soy and coconut.
