Fermented Cheeses & Their Benefits

Tough To Get Right But When Done Well The Uses Are Endless

Cheese is one of the oldest and most diverse ways humans have transformed milk into food. Behind Cheddar, Stilton, Brie, Gouda and thousands of regional cheeses is a remarkable combination of milk, microorganisms, time, temperature, salt and the knowledge of the person making it.

For BFFD, fermented cheese is particularly interesting because it sits at the meeting point between farming, food production and traditional craft. A finished cheese can carry the influence of the milk, animal, farm, cheesemaker, cultures, maturation process and landscape that produced it.

The phrase fermented cheeses is often used to describe cheeses in which bacteria, yeasts or mould cultures play an important role in turning milk into the finished cheese. Fermentation usually begins when microorganisms convert lactose in the milk into lactic acid. From there, cultures, enzymes, moulds, moisture and maturation can help create everything from the sharpness of a mature Cheddar to the blue veins of Stilton.

What Is Fermented Cheese?

Fermented cheese is cheese produced with the involvement of microorganisms such as lactic acid bacteria and, depending on the cheese, particular moulds or other cultures. These microorganisms help acidify the milk and can contribute to flavour, aroma, texture and maturation.

The term “fermented cheese” is useful for consumers, but it is not one single category of cheese. Different cheeses undergo very different fermentation and maturation processes.

Importantly, fermented does not automatically mean probiotic, raw milk, unpasteurised or still containing live cultures when eaten.

Is Cheese Fermented?

In most traditional cheesemaking, microbial fermentation forms part of the production process.

Starter cultures are commonly introduced to milk. These microorganisms consume lactose and produce lactic acid. As acidity changes, the milk begins moving towards the conditions required for curd formation and cheese production.

The process does not stop there.

Depending on the cheese, its eventual character can then be shaped by:

This explains why two cheeses that begin with milk can become completely different foods.

A young soft cheese might be mild and creamy. A mature hard cheese can become dry, crystalline and intensely savoury. A blue cheese develops mould throughout the interior, while a bloomy rind cheese develops its characteristic surface from specific cultures.

What Happens During Cheese Fermentation?

At its simplest, microorganisms begin changing the milk.

Lactic acid bacteria convert some of the milk sugar into lactic acid. This changes the acidity of the milk and contributes to the formation and development of the cheese.

The curds are then separated from whey and processed according to the type of cheese being made.

But fermentation and maturation can continue changing the cheese long afterwards.

Proteins and fats gradually break down into smaller compounds. These transformations contribute to the flavours, aromas and textures associated with mature cheese.

That is why ageing is not simply a case of leaving cheese on a shelf. A maturing cheese is changing.

Types of Fermented Cheese

There is no single flavour or texture that defines fermented cheese. Some are mild. Some are extraordinarily powerful. Some are soft enough to spoon. Others can mature into hard cheeses capable of ageing for years.

Hard and Mature Cheeses

Cheeses such as mature Cheddar, Parmesan style cheeses and some aged Gouda styles undergo substantial changes during maturation. As they mature, they can develop increasingly complex savoury, nutty, buttery or sharp flavours. For British food lovers, traditional Cheddar is perhaps one of the clearest examples of how fermentation, cheesemaking technique and maturation work together.

Blue Cheeses

Blue cheeses use particular mould cultures to create the distinctive blue or green veining found throughout the cheese. British examples include Stilton and many independent regional blue cheeses. Their flavour can range from creamy and relatively gentle to powerful, salty and intensely savoury.

Bloomy Rind Cheeses

Brie and Camembert style cheeses develop a characteristic pale rind through mould cultures growing across the surface. The cheese often becomes softer as it matures, particularly beneath the rind. British cheesemakers now produce numerous cheeses using similar techniques.

Washed Rind Cheeses

Washed rind cheese develops through repeated treatment of the exterior during maturation. The resulting surface microorganisms can create particularly distinctive aromas and flavours. These cheeses can be much stronger smelling than their interior flavour might suggest.

Fresh and Young Cultured Cheeses

Not every cultured cheese requires months of maturation. Some cheeses are made relatively quickly using bacterial acidification and are eaten young. The fermentation process can therefore be important even where the finished cheese is fresh rather than aged.

Examples of Fermented Cheeses

People searching for fermented cheese examples are likely to encounter familiar cheeses including:

British Fermented Cheeses

Britain has an extraordinary cheesemaking culture. Cheddar and Stilton may be internationally recognised, but they represent only a fraction of what is now being produced across the country.

Independent British cheesemakers work with cow, goat, sheep and buffalo milk and produce everything from soft mould ripened cheeses to mature farmhouse Cheddar, blue cheese, washed rind cheese and experimental small batch varieties.

For BFFD, this is exactly the kind of food economy worth making easier to discover. A search for fermented cheese should eventually be able to lead somebody towards an actual cheesemaker, farm shop, dairy or cheesemonger rather than ending with a generic explanation.

Fermented Cheese and Milk

Milk is where the story begins. Cheese may be produced from different types of milk, including:

The animal, breed, diet, season, farming system and milk composition can all influence the cheesemaking process and final product. Some cheeses are produced using pasteurised milk. Others may use raw or unpasteurised milk where legally and safely produced.

These terms should not be confused with fermentation. A cheese can be fermented whether the original milk was pasteurised or unpasteurised.

What We Like to Eat With Fermented Cheese

One of the easiest ways to understand good cheese is to eat it alongside relatively simple food.

How to Store Your Fermented Cheese

There is no single storage instruction suitable for every cheese.

Fresh cheese, mature hard cheese, blue cheese and soft mould ripened cheese can have different storage requirements.

Always follow the maker or retailer’s instructions.

Once opened, protecting the cheese from excessive drying while still storing it appropriately can help maintain quality.

For BFFD, we should avoid pretending that one universal storage method applies to every fermented cheese.

Why Fermented Cheese Matters to BFFD

Fermented cheese is a particularly good example of why local food needs more than a supermarket shelf. Behind a finished cheese can be a farm, a herd, a milk supply, a cheesemaker, a maturation room, generations of knowledge and months or even years of work.

BFFD is being built to make more of that story visible. Finding fermented cheese should eventually mean more than learning what fermentation is. It should help somebody discover who is making remarkable cheese in Britain, where they can buy it and how their money can travel more directly towards the people producing the food.

FAQ

What is fermented cheese?

Fermented cheese is cheese whose production involves microorganisms such as lactic acid bacteria and, in certain styles, moulds or other cultures. These microorganisms contribute to acidification, flavour, texture and maturation.

Is all cheese fermented?

Microbial activity is fundamental to the production of many cheeses, although cheesemaking methods vary significantly. “Fermented cheese” is therefore best treated as a broad consumer description rather than one precise cheese category.

What are examples of fermented cheeses?

Examples can include Cheddar, Stilton, Gouda, Brie, Camembert, Parmesan style cheeses, blue cheeses and many traditional farmhouse cheeses.

Is Cheddar fermented?

Traditional Cheddar production involves bacterial cultures that acidify the milk, followed by cheesemaking and maturation processes that develop the finished cheese.

Is fermented cheese the same as probiotic cheese?

No. Fermentation does not automatically mean a finished cheese should be described as probiotic.

Are fermented cheeses always aged?

No. Fermentation and maturation are related but separate processes. Some cheeses are eaten young while others mature for many months or years.

Is fermented cheese vegan?

Traditional cheese is produced from animal milk and therefore is not vegan. Plant based fermented products are a separate category and should not automatically be described as cheese without considering applicable food naming rules.

Where can I buy fermented cheese in the UK?

Fermented and traditionally made cheeses can be found through cheesemakers, farm shops, cheesemongers, farmers markets, specialist retailers and online cheese sellers. BFFD is being built to make independent British suppliers easier to find.

Find Fermented Cheese From British Cheesemakers

Good cheese is more than milk transformed into something delicious. It can carry the character of the farm, the animals, the maker, the cultures and the place in which it matured. BFFD is being built to make those connections easier to find.
