Cheddar cheese is orange due to the addition of colouring agents like annatto, a natural food colouring derived from the seeds of the tropical achiote tree, or paprika. In the 17th century, English cheesemakers produced cheese with a yellow tone due to the milk from cows that grazed on beta-carotene-rich grass. This yellow hue was seen as a marker of high-quality cheese, so some cheesemakers added colouring agents like saffron, marigold, and carrot juice to their cheese to mimic the appearance of high-quality cheese.

The natural colour of cheddar cheese is a light, creamy yellow
In the 17th century, English cheesemakers produced cheese with a yellow tone due to the milk from certain cows. These cows, often Jersey and Guernsey breeds, grazed on grass that was packed with beta-carotene, which gave the milk an orange-yellow tone. At the time, cheddar cheese with a yellow hue was considered a sign of quality. As a result, some cheesemakers would add colouring agents like carrot juice, saffron, and marigold to their cheese to make it appear higher quality.
Over time, the colour orange became associated with cheddar cheese, and cheesemakers began to add annatto, a natural food colouring derived from the seeds of the tropical achiote tree, to give their cheese the familiar orange hue. Annatto has been used to dye cheese for more than 200 years and does not significantly affect the flavour or texture of the cheese.
Today, the orange colour of cheddar cheese is often simply a matter of tradition and visual recognition. The colour has become so associated with cheddar cheese that many people expect the cheese to be orange. Additionally, the colour can help distinguish cheddar from other types of cheese, such as the typically white cheese made in New England and New York.
It is worth noting that the colour of cheddar cheese can also vary depending on the diet of the cows producing the milk. Pasture-fed cows can produce milk with a tinge of orange beta-carotene, resulting in cheese with a more yellowish or orange hue. However, modern dairy practices have reduced the seasonal variation in milk colour, resulting in more consistent cheese colours throughout the year.

The orange colour comes from the addition of annatto, a food colouring
The orange colour of cheddar cheese comes from the addition of annatto, a natural food colouring. Annatto is derived from the seeds of the tropical achiote tree, which is native to Central and South America. The seeds are ground into a red powder and added to cheese to give it an orange hue. This practice of colouring cheese with annatto was first started by early American settlers and has since become a tradition, with many manufacturers of cheddar cheese continuing to use this natural dye to create the expected orange colour.
The addition of annatto does not significantly affect the flavour or texture of the cheese. Instead, it is added purely for visual purposes, to create a consistent colour that consumers associate with cheddar cheese. The amount of annatto added to cheese is relatively small, and it is used to standardise the colour of cheese throughout the year, as the natural colour of milk can vary depending on the diet of the cows.
Historically, cheddar cheese obtained its yellow or orange colour from the milk of cows that grazed on grass rich in beta-carotene. Over time, cheesemakers began to add natural dyes, such as carrot juice, saffron, and marigold, to their cheese to enhance its colour and make it appear higher quality. This practice of adding colour to cheese has continued to the present day, with annatto being the most commonly used dye to create the distinctive orange shade of cheddar cheese.
It is worth noting that not all cheddar cheese is dyed orange, and there are variations in different parts of the world. For example, in the United Kingdom, where cheddar cheese originates, it is typically a creamy colour, and the addition of dye is not as prevalent. In the United States, however, the orange colour of cheddar cheese has become standardised, and it is commonly sold as "American cheese" or "burger cheese".

In the 17th century, orange cheddar was a marker of high-quality cheese
Cheddar cheese, which originated in the village of Cheddar in Somerset, England, was traditionally produced from the milk of cows that grazed on the region's beta-carotene-rich pastures. This resulted in a cheese with a distinctive yellowish or orange hue. Over time, this colour became associated with high-quality cheese, as it indicated the presence of rich, creamy milk from grass-fed cows.
However, not all cheesemakers had access to milk from grass-fed cows, and some began to engage in fraudulent practices to make their cheese appear more desirable. They added dyes and colouring agents like saffron, marigold, and carrot juice to their cheese to mimic the orange hue of high-quality cheddar. This practice became known as "early visual branding" and allowed cheesemakers to mask the white colour of their cheese, which was often due to the use of lower-fat milk or the skimming of cream for butter production.
The tradition of colouring cheese to indicate quality carried over to the United States, particularly in states like Indiana, Ohio, Wisconsin, and New York. Cheesemakers in these states added colouring to their cheese to ensure a uniform colour throughout the year, as the colour of the cheese varied depending on the cows' diet of grass or hay. The colour orange became so strongly associated with cheese that it influenced the colour of processed cheese products like Cheetos.
Today, the colour orange in cheddar cheese is typically achieved using annatto, a food colouring made from the seeds of the achiote tree, or paprika. While the colour does not significantly affect the flavour or texture of the cheese, it continues to be added to meet consumer expectations and for visual recognition.

Producers of lower-quality cheese added pigment to mimic the colour of high-quality cheese
In the 17th century, cheddar cheese was produced from cows that grazed on grass rich in beta-carotene, which gave their milk an orange-yellow tone. This hue became associated with high-quality cheese, and producers of lower-quality cheese soon caught on. They began adding pigments from natural sources such as saffron, marigold, and carrot juice to mimic the colour of high-quality cheese and make their product seem more appealing to consumers. This practice of "early visual branding" helped standardise the colour of cheese throughout the year, as the natural colour of milk varied with the seasons, becoming more golden in the summer due to the fresh forage cows ate.
The addition of pigment to cheese was not limited to England, and the trend of orange-hued cheddars eventually made its way to the United States with early American settlers. Cheesemakers in Wisconsin, Ohio, and Indiana adopted this technique to distinguish their product from the white cheese made in New England and New York. The colour orange became so strongly associated with cheese that it influenced the colour of processed cheese products like American cheese and Cheetos.
While the use of natural pigments like marigold and carrot juice has largely been replaced, the practice of adding colour to cheddar cheese persists to this day. Most modern cheesemakers use annatto, a natural food colouring derived from the seeds of the tropical achiote tree, to give their cheese the familiar orange hue. Annatto has been used to dye cheese for over 200 years and is responsible for the consistent colour of cheddar throughout the year. While the colour of cheddar cheese has been standardised, the cheesemaking process and the age of the cheese remain the most important factors in determining its quality and flavour.

The colour orange became associated with cheese, which is why American cheese is also orange
The colour of cheese in its natural state ranges from shades of white to creamy yellow. However, the addition of dyes, particularly annatto, has led to the association of cheese with the colour orange. Annatto is a natural food colouring derived from the seeds of the tropical achiote tree, which gives cheese a rich orange hue. The use of annatto to dye cheese can be traced back over 200 years, and it is still commonly used today.
The origin of orange cheese can be traced back to 17th-century England, where cheddar cheese was produced from cows that grazed on grass rich in beta-carotene, resulting in milk with an orange-yellow tone. This orange hue became associated with high-quality cheese, and cheesemakers of lower-quality, lower-fat cheese began adding pigments from natural sources such as saffron, marigold, and carrot juice to mimic the colour of premium cheese.
As cheesemaking spread to other regions, such as the United States, cheesemakers continued the practice of adding dyes to standardise the colour of their cheese throughout the year. The colour of cheese can vary depending on the diet of the cows, with beta-carotene-rich grass in spring producing a different colour than hay in winter. By adding dyes, cheesemakers could ensure a uniform colour for their products.
Over time, the colour orange became strongly associated with cheese, especially in the United States. This is why American cheese, as well as cheese-based snacks like Cheetos, are often brightly coloured. The use of annatto to dye cheese has become a tradition, and many manufacturers continue to use it to meet consumer expectations and maintain brand recognition.
It is worth noting that not all American cheddar is dyed orange. In some regions, such as Wisconsin, aged cheddar is white, while unaged cheddar is orange. Additionally, in other countries like Ireland and Australia, white cheddar is more commonly found than the orange variety.

Frequently asked questions
In its natural state, cheddar cheese is white or yellowish in colour. The orange colour comes from dyes, such as annatto, a food colouring made from the seeds of the achiote tree, or carrot juice. In the past, the colour of cheddar cheese was influenced by the diet of the cows producing the milk. In the spring and summer, when cows ate fresh grass, their milk had higher levels of beta-carotene, resulting in cheese with a deeper yellow colour.
The addition of orange dye to cheddar cheese began as a way to standardise the colour of the cheese throughout the year. Seasonal fluctuations in grass and feed nutrients caused variations in the milk colour, so cheesemakers added dyes to maintain the visual recognition of their regional cheese. The colour orange also became associated with high-quality cheese, so some manufacturers added dye to their lower-quality cheese to make it appear more desirable.
The orange colour in cheddar cheese does not affect its flavour or texture. The difference between orange and white cheddar cheese lies mainly in the cheesemaking process, such as the culture used, milk choice, and aging. Therefore, the choice between orange and white cheddar is primarily based on personal preference.
