Blue cheese is a delicious treat, but is it gluten-free? Cheeses are naturally gluten-free, but blue cheese is an exception due to the way it is made. Traditionally, the milk used to make blue cheese is inoculated with mold spores grown on bread or cultures that may contain gluten. However, modern cheese-making techniques have made it less necessary to use bread as a mold-growing medium. Some companies clearly state that their blue cheeses are gluten-free, but it is important to verify this before consuming, especially if you have a gluten intolerance or allergy. Reactions to blue cheese vary from person to person, and some people with gluten sensitivities may react to lactose in dairy products.

Blue cheese is traditionally made using mould spores grown on bread or rye, which contain gluten
Blue cheese has traditionally been made using mould spores grown on bread or rye, which contain gluten. This has led to a controversy over whether blue cheese is gluten-free. While most cheeses are naturally gluten-free, blue cheese's mould spores are sometimes grown on rye or wheat bread, which contain gluten.
The controversy centres around the question of whether these cheeses contain gluten. Some people argue that modern cheese-making techniques have made bread obsolete as a mould-growing medium. Additionally, some companies clearly state on their websites that their blue cheeses are gluten-free. However, others argue that there are still artisans who use traditional practices, and some blue cheeses on the market may contain gluten.
It is important to note that the presence of gluten in blue cheese may depend on the manufacturer and the specific type of blue cheese. Some brands may use gluten-containing ingredients, such as wheat, barley, or rye, in their cheese-making process. For those with gluten sensitivities or celiac disease, it is crucial to carefully read the labels and verify the gluten content before consuming any type of blue cheese.
While blue cheese has traditionally been made using mould spores grown on gluten-containing bread or rye, it is worth noting that not all blue cheeses are created equal. Some manufacturers have started using gluten-free mould cultures, such as Rosenborg blue cheese. Other brands like BelGioso, Dutch Farms, Litehouse, Organic Valley, and Rogue Creamery also offer versions of blue cheese that are not fermented in gluten-based spores.
When it comes to blue cheese and gluten content, it is always advisable to be cautious and informed. Those with gluten sensitivities or celiac disease should carefully read labels, consult gluten-free product lists, and observe their body's reactions to different foods.

Modern techniques have made bread obsolete as a mould-growing medium
Blue cheese is a type of cheese characterised by the growth of blue mould and veining in air spaces inside the cheese, giving it a distinctive flavour, smell, and texture. It is typically made by inoculating milk with specific blue cheese moulds, such as Penicillium roqueforti, and allowing the mould to spread through the creation of tiny openings in the cheese.
Traditionally, blue cheese was made by growing mould spores on bread, which often contained gluten. This led to concerns about the presence of gluten in blue cheese and its suitability for gluten-free diets. However, modern techniques have made bread largely obsolete as a mould-growing medium in blue cheese production.
Today, most cheesemakers purchase pre-grown mould spores in powder form and add them directly to the milk at the beginning of the cheese-making process. This "forced" blueing from pre-packaged moulds develops quickly and results in a consistent cheese with specific flavour profiles. The use of pre-grown mould spores eliminates the need for bread as a mould-growing medium, addressing the potential gluten issue associated with traditional methods.
Additionally, some companies have started producing blue cheeses cultured in wheat-based dextrose, which is gluten-free. Examples include Rosenborg blue cheese, which is made using gluten-free mould cultures, and brands like BelGioso, Dutch Farms, Litehouse, Organic Valley, and Rogue Creamery, which offer blue cheeses not fermented in gluten-based spores. These modern techniques and alternatives ensure that blue cheese can be enjoyed by those with gluten sensitivities or aversions.
While the majority of cheeses are naturally gluten-free, it is important to read the labels of packaged or processed cheeses to verify their gluten content. Some shredded cheeses may contain starch or cellulose to prevent clumping, but these additives typically do not contain gluten. However, if the cellulose is derived from wheat, it should be declared on the label. Therefore, reading labels is crucial for individuals adhering to a gluten-free diet who wish to consume blue cheese or any other type of cheese.

Some companies clearly state their blue cheeses are gluten-free
There is some debate about whether blue cheese is gluten-free. Some people have reported adverse reactions to consuming blue cheese, while others have not. This suggests that individual sensitivity to gluten may play a role in how one's body reacts to blue cheese.
Traditionally, blue cheese has been made using mould spores grown on gluten-based bread. However, modern cheese-making techniques have made it less necessary to use bread as a mould-growing medium. As a result, some companies now produce blue cheese that is gluten-free.
Some companies clearly state on their websites that their blue cheeses are gluten-free. For example, Rosenborg blue cheese is made using mould cultures that are gluten-free, making it safe for people with gluten aversions, including those with celiac disease. Other companies that produce gluten-free blue cheese include BelGioso, Dutch Farms, Litehouse, Organic Valley, and Rogue Creamery. These companies use gluten-free spores to ferment their blue cheese.
It is important to verify the gluten-free status of blue cheese before consuming it, especially for those with gluten sensitivities or celiac disease. While most blue cheeses on the market today are unlikely to contain gluten, there may still be some produced using traditional methods that could contain traces of gluten. Checking the labels and ingredients of blue cheese products can help ensure they are free from gluten-containing ingredients such as wheat, barley, rye, or their derivatives.

People with gluten intolerance have reported adverse reactions to blue cheese
Blue cheese is traditionally made using mould spores grown on bread or cultures that contain gluten. However, modern cheese-making techniques have made bread obsolete as a mould-growing medium. As a result, there is strong evidence that relatively few blue cheeses on the market contain gluten.
Despite this, people with gluten intolerance have reported adverse reactions to blue cheese. For example, one person with gluten intolerance commented that they had a strong reaction to Roquefort cheese. They checked with a friend with celiac disease who confirmed that she reacts strongly to several blue cheeses and avoids them altogether.
Another person with gluten intolerance reported reacting to blue cheese in the past, but not experiencing any problems recently. This could be because newly diagnosed celiacs may initially react to lactose, a common issue until their gut has time to heal.
The Canadian Celiac Association (CCA) has added blue cheese to its "Acceptability of Food and Food Ingredients for the Gluten-Free Diet" pocket dictionary. This means that blue cheese should not bother people with celiac disease or gluten intolerance. However, the CCA also advises that individuals should carefully observe their body's reaction to blue cheese, especially if they have a food allergy to gluten or dairy.
Ultimately, it is important to let your body and your level of sensitivity be your guide when it comes to consuming blue cheese. If you are highly sensitive to gluten, it may be best to avoid blue cheese altogether, or to look for blue cheeses cultured in wheat-based dextrose, which should not contain gluten.
