What Is Blue Cheese? Blue Heaven! Here Is Our FAQ.

Are you here to get a few answers about your favorite tangy, rich, blue cheese? So, what is blue cheese? We did a little digging and came up with a few answers for you.

So you love blue cheese. But how is blue cheese made?

Some people dread eating blue cheese for fear it might contain toxins and cause sickness. 

Contrary to this belief, the mold used in making blue cheese is safe for consumption and contains no harmful toxins.  

Well-known varieties include French Roquefort, English Stilton, and Italian Gorgonzola. 

Blue cheese is best with fruits and nuts and can mix well with other types of cheese. Garnish it into dressings, sauces, and soups, or use it as toppings on salads.

Blue cheese is a type of cheese that allegedly originated way back in the 7th century. 

According to the legend, a shepherd accidentally invented blue cheese after he left his lunch of bread and cheese in a cave. 

When he returned to the cave, he discovered that his cheese was covered with a common fungus found widespread in nature. 

Today blue cheese production involves the addition of refined mold culture to the cheese milk and “needling,” a process wherein thin needles or skewers are pierced into the cheese to allow the air in, encouraging the mold to spread and then resulting in the distinctive blue veins in blue cheese. 

Cheesemakers also add salt to the cheeses to prevent spoilage and let them age for one to six months. 

Generally, blue cheese has a salty and strong, sharp taste with a pungent aroma. However, this may vary depending on its variety. 

Other kinds of blue cheese sold in the market today sometimes feature creamy and mildly earthy flavor profiles with a soft texture. 

For the record, some of the well-known blue cheese types are Gorgonzola, Castello creamy blue, Roquefort, Danish blue, and Stilton. 

Blue cheese is often present on cheese boards, alongside fruits and nuts, and used to elevate the taste of salads, pasta dishes, and sauces. 

What does blue cheese taste like?

When it comes to blue cheese taste, it has a salty and sharp flavor with a pungent aroma.

However, this flavor profile varies depending on the type of blue cheese you’ve purchased. 

Gorgonzola blue cheese has a soft textural nuance with a buttery and creamy flavor when “young,” while the aged version of the cheese tends to have an earthier and stronger flavor. 

Meanwhile, one of the oldest blue cheeses, Roquefort has a creamy texture with a sharp and sweet flavor profile. 

Whether crumbled and stirred into a dressing, seared on top of steak or roasted on top of vegetables, blue cheese has a strong tangy flavor first, with a smooth, creamy finish.

How is blue cheese made?

As mentioned, blue cheese is made from pasteurized cow, goat, or sheep’s milk that’s cured with cultures of the mold, penicillium roqueforti.

The making process starts by pasteurizing the milk to kill any harmful bacteria and then undergoing a homogenization process to break out the fats, giving the cheese a smooth and creamy texture. 

Once done, the bacterial culture begins. 

This process converts the natural sugar of the milk into lactic acid, then eventually turns the product into cheese. 

Blue cheese gets its signature blue color by adding mold, penicillium. 

No, blue cheese won’t cure any conditions; it’s not that kind of penicillin. 💊

After that, an enzyme called rennet is added to the mixture to make the milk curdle to the consistency of yogurt. 

Once the curdling is done, the milk separates into curds and whey. 

The mixture then undergoes more than an hour of stirring until the curd is firm enough to be taken from the mix. 

The curds are then transferred into a circular fold and salted to prevent spoilage. 

Once the cheese is firm and flavored, it undergoes “needling,” a process wherein thin needles or stainless steel rods are pierced into the cheese to allow the air in. 

This essential procedure encourages the mold to spread, resulting in the distinctive blue veins in blue cheese. 

The cheese is then gone through a ripening process wherein the dairy product is kept in a room with a 46 to 50°F temperature for about a month or up to six months. 

The longer it ripens, the deeper the flavor.

How to store blue cheese

Like any other type of cheese, blue cheese does go bad. But don’t be sad, as there’s a great way to extend its shelf life even further—storing blue cheese in the refrigerator! 

To do it, here are the steps you need to follow:

  1. Wrap your blue cheese in cheese paper or beeswax wrap. 
  2. Place the wrapped cheese in a more humid section of your fridge. Storing this way prevents the cheese from drying out.

Blue cheese stored at room temperature on the kitchen counter will last only a few days. 

Meanwhile, if properly stored in the refrigerator, you can enjoy the cheese for up to four weeks. 

Blue cheese that has become inedible has a fuzzy mold on the surface, visually differing from the veins of blue mold that were added in a clean, controlled environment by the cheesemaker. Expired blue cheese looks dull, crumbles have become solid and often dry, and it no longer has a strong but cheesy aroma, instead the offensive waft of “bad” food. 

Pro tip: Bring your refrigerated cheese to room temperature for about an hour before serving it.

Can you freeze blue cheese?

Yes, it’s possible to freeze blue cheese. But keep in mind that the longer it stays in the freezer, the texture of the cheese won’t be as good as the fresh one. 

Frozen blue cheese tends to have a crumbly and grainy texture, however, freezing blue cheese can extend its storage life for up to six months.

How to use blue cheese

There are a few ways to use and enjoy blue cheese, including toppings for soup, steak, and salads, in dressing, and stuffed into green olives!

Blue cheese is a versatile ingredient that’s best suited to stand out on its own on cheese boards, thanks to its nice flavors and textural nuances. 

Blue cheese can be broken into smaller pieces and blended with mayonnaise and sour cream to create a creamy salad dressing like my beloved version of the blue cheese dressing. 

You’d also love using blue cheese alongside red or sparkling wine to unlock a fuller flavor on your palate. 

Or pair the cheese with whole-grain crackers, marcona almonds, or dried fruits such as apricots, raisins, fresh figs, and pears.

Moreover, you can incorporate blue cheese flavor into your favorite steak dish by crumbling a good blue onto the meat as it sears.

Does blue cheese have mold?

Yes, blue cheese contains penicillium roqueforti, a kind of mold that’s behind the unique blue hue of the cheese as well as its taste and aroma.

However, according to USDA, this type of mold is safe for consumption and doesn’t produce toxins that are harmful to humans.

Is blue cheese pasteurized?

When it comes to commercially-made blue cheese in the United States, most of them are pasteurized by default

However, some products found at a farmer’s market or grocery stores are unpasteurized, so it’s best to read the label before purchasing one. 

If it doesn’t clearly state that the cheese is made from pasteurized milk and you’re following a strict diet, then it’s recommended to avoid it.

Types of blue cheese

There are several of blue cheese; some of you might see them in the dairy aisle, and some you may not hear of or have never seen. 

Here’s a list of the most popular types of blue cheese that can get you started:

English Stilton

English Stilton is one of the famous members of the blue cheese family. 

It’s made with fresh pasteurized cow’s milk and named after a village in Huntingdonshire, England. 

The classic English blue cheese has a rich, intense flavor that’s less salty than his cousin, Roquefort. 

According to Britannica, this cheese features a semisoft and moist or creamy texture with ivory yellow color and bluish-green veins of Penicillium glaucum mold.

French Roquefort

Reportedly one of the oldest known cheeses, French Roquefort or simply Roquefort is made with sheep’s milk, with a notable sharp, tangy, and salty flavor profile, blue-colored veins, and rich, creamy texture. 

Fun fact: Roquefort was reportedly the favorite cheese of the 8th-century Frankish king, Charlemagne, and it was called “le fromage des rois et des papes” or (“the cheese of kings and popes”).

Spanish Cabrales

Another blue cheese variety popular in the culinary world is Cabrales (queso de Cabrales). 

Cabrales is made in pure, unpasteurized cow’s milk, but sometimes it can be a mixture of two or three varieties of milk (milk, sheep, and goat). 

It’s considered a fatty cheese with a minimum ripening period of two months in limestone caves; you can easily spot it in the market due to its green aluminum foil wrap. 

Cabrales cheese is famous for its strong aroma, sharp, acidic, and slightly salty taste, creamy and firm texture, and bluish veins of Penicillium.

Danish Danablue

Commonly known as Danish blue, Danish Danablue or danablue is another type of blue cheese. 

It’s well-known for its semi-soft texture, off-white, creamy white, or light yellow appearance, and distinct blue veins.

As per its flavor profile, Danish blue offers a biting and salty undertone with an aroma characterized as strong.

Italian Gorgonzola

Famous in n the northern Italian regions of Piedmont and Lombardy, Gorgonzola, this blue cheese variety is made with unskimmed cow’s milk with three to four months of ripening period. 

Pure gorgonzola has a crumbly, soft texture, a nice, nutty aroma, and a taste ranging from mild to sharp, depending on its age.

What is the blue in blue cheese?

As mentioned above, the blue spots or veins that appeared in most blue cheese are due to the growth of the mold Penicillium in the dairy. 

This kind of mold is edible and doesn’t produce toxins, which makes it safe for human consumption.
