Goat cheese is predominantly white or off-white in colour, in contrast to the yellow hue of cow's cheese. This difference is due to the lower levels of beta-carotene in goat's milk, which is influenced by the animal's diet and digestive system. Goats have a more diverse and selective diet, consuming a wider range of vegetation, including leaves, shrubs, and woody plants that are lower in carotenoids. Additionally, their digestive enzymes efficiently break down carotenoids, preventing the accumulation of beta-carotene in their milk. While the colour of goat cheese is typically white, variations exist, such as the almond-coloured Le Chevrot or the bright white Humboldt Fog.

Goat cheese is white due to lower levels of beta-carotene in goat's milk
The colour of cheese is influenced by several factors, including the composition of the milk, added ingredients, the fermentation process during maturation, and maturation time. The colour of the milk, in turn, is influenced by the diet of the milk-producing animal.
Goat cheese is white due to lower levels of beta-carotene in goats' milk. Beta-carotene is a natural pigment and a type of carotenoid found in plants, especially those with a deep orange or yellow colour, such as carrots and grass. Cows consume these plants as part of their diet, and the beta-carotene is absorbed into their bloodstream, eventually accumulating in the milk-producing glands and giving cows' milk its characteristic yellow hue.
Goats, on the other hand, have a more diverse and selective diet. While cows primarily graze on grass and carotenoid-rich plants, goats consume a wider range of vegetation, including leaves, shrubs, and even some woody plants that are lower in carotenoid content. This variation in diet results in lower intake of carotenoids and, consequently, lower levels of beta-carotene in goats' milk.
Additionally, goats have specific enzymes in their digestive system that efficiently break down carotenoids. These enzymes metabolise and degrade beta-carotene, preventing its accumulation in the milk. In contrast, cows may have fewer of these specialised enzymes, allowing a larger portion of ingested carotenoids to pass through their digestive system and into their milk.
The lower levels of beta-carotene in goats' milk result in the white or off-white colour of goat cheese. This natural colour of goat cheese, devoid of the yellow hue seen in cow milk cheeses, reflects the inherent characteristics of the milk it is made from.

Cow's milk and cheese are often yellow due to beta-carotene in the grass cows eat
The colour of cheese is influenced by several factors, including the composition of the milk, added ingredients, the fermentation process, and maturation time. The amount of fat and protein in the milk, as well as any added herbs, dyes, or spices, can alter the colour of the final product.
Cows' milk and cheese often have a yellow hue due to the presence of beta-carotene, a type of carotenoid pigment found in grass and other plants consumed by cows. Beta-carotene is a bright orange pigment that, when ingested by cows, is absorbed into their bloodstream and eventually accumulates in their milk. During the cheesemaking process, beta-carotene concentrates in the milk fat, naturally colouring the cheese yellow. The intensity of the yellow colour can vary depending on factors such as cow diet and cheese type, with full-fat cheeses typically containing higher levels of beta-carotene than low-fat varieties.
Beta-carotene is also a vital nutrient that plays a role in the nutritional benefits of cheese. It acts as an antioxidant and is converted into vitamin A in the body, contributing to its nutritional richness. In many cultures, the yellow colour of cheese has become a symbol of quality and nutritional value.
On the other hand, goat cheese is known for its characteristic white or off-white colour. Goats have a more diverse and selective diet than cows, consuming a wider range of vegetation, including leaves, shrubs, and woody plants that are lower in carotenoid content. Additionally, goats have specific enzymes in their digestive system that efficiently break down carotenoids, preventing the accumulation of beta-carotene in their milk. As a result, goat cheese lacks the yellow hue seen in cow milk cheeses, maintaining its natural white appearance.
The difference in the colour of cheese produced by cows and goats is primarily due to the variation in their diets and the resulting levels of beta-carotene in their milk. Cows that graze on grass and plants rich in carotenoids produce milk with higher beta-carotene levels, leading to the yellow colour in cow cheese. In contrast, goats' diverse diet and efficient carotenoid breakdown result in lower beta-carotene levels and white cheese.

Goat cheese can vary in colour from ivory to snow-white
Goat cheese is well-loved for its tangy, buttery, and slightly acidic taste. It is also known for its distinctive colour, which can vary from ivory to snow-white. This natural colour is due to the lower levels of beta-carotene in goat's milk, which is influenced by the animal's diet and digestive system.
Goats have a more diverse and selective diet than cows, consuming a wider range of vegetation, including leaves, shrubs, and even some woody plants. This variation in diet results in a lower intake of carotenoids, which are pigments found in plants with deep orange or yellow colours, such as carrots and grass.
Additionally, goats have specific enzymes in their digestive system that efficiently break down carotenoids. These enzymes metabolise and degrade beta-carotene, preventing its accumulation in the milk. In contrast, cows may have fewer of these specialised enzymes, allowing a larger portion of ingested carotenoids to pass through their digestive system and tint their milk with a yellow hue.
The colour of goat cheese can also be influenced by other factors, such as added ingredients, the fermentation process, and maturation time. For example, some goat cheeses are washed in red wine, giving them a violet rind, while others are sprinkled with ash, resulting in a foggy grey colour. Despite these variations, the natural colour of goat cheese typically falls within the ivory to snow-white range.
In summary, the colour of goat cheese can vary from ivory to snow-white due to a combination of factors, including the diet and digestive system of the goat, as well as any added ingredients or production techniques used during the cheesemaking process.

Goat cheese can be washed in red wine, giving it a violet rind
Goat cheese is predominantly white, while cow's cheese is usually yellow. This difference in colour is due to the varying levels of beta-carotene in the milk of goats and cows. Beta-carotene is a natural pigment found in plants, especially those with deep orange or yellow colours, such as carrots and grass. Cows consume these plants, absorbing the beta-carotene and excreting it in their milk, giving it a yellow hue. Goats, on the other hand, have a more diverse and selective diet, often consuming leaves, shrubs, and even woody plants that are lower in carotenoids. Additionally, goats have specific enzymes in their digestive system that efficiently break down carotenoids, preventing the accumulation of beta-carotene in their milk. As a result, goat cheese maintains its natural white or off-white appearance.
However, goat cheese can undergo treatments that alter its colour. One such example is the Mitica® Drunken Goat®, a goat's milk cheese produced in the village of Jumilla in Murcia, Spain. This cheese is soaked for 48 to 72 hours in Doble Pasta red wine, a twice-fermented wine made with a high concentration of black grape skins. The wine bath gives the cheese a unique fruity flavour and a deep violet hue on its rind, while the inner paste remains a bright white colour. This colour contrast creates a striking visual effect, making it a beautiful addition to any cheese board.
The process of washing goat cheese in red wine, as seen with the Drunken Goat® cheese, results in a violet rind due to the interaction between the wine and the cheese. The high concentration of black grape skins in the Doble Pasta wine contributes to the development of the violet colour. During the curing process, the wine penetrates the rind of the cheese, infusing it with the colour and flavour of the grapes. The longer the cheese is soaked in the wine, the more intense the violet hue becomes.
It is important to note that not all goat cheeses are washed in wine or treated with artificial colourings. The natural colour of goat cheese can vary slightly depending on factors such as the diet of the goats, the composition of their milk, and the maturation time of the cheese. However, the white or off-white colour is a characteristic feature of traditional goat cheese, and it is this pristine whiteness that many cheese connoisseurs find captivating.
In conclusion, while goat cheese is typically white due to the lower levels of beta-carotene in goat's milk, innovative cheese-making techniques, such as washing the cheese in red wine, can alter its colour. The Drunken Goat® cheese is a testament to this transformation, as the wine-washing process gives it a violet rind, creating a visually appealing and flavourful addition to any cheese platter.

Goat cheese can be sprinkled with ash, giving it a grey colour
Goat cheese is predominantly white or off-white in colour. This is due to the lower levels of beta-carotene in goat's milk compared to cow's milk. Beta-carotene is a natural pigment found in plants, especially those with a deep orange or yellow colour, such as grass. Cows consume these plants as part of their diet, and the pigment is absorbed and excreted in their milk, giving it a yellow hue. Goats, on the other hand, have a more diverse and selective diet, consuming a wider range of vegetation, including leaves, shrubs, and even some woody plants, which are lower in carotenoid content.
However, not all goat cheeses are white. Some varieties, such as Bonne Bouche and Grey Owl, are known for their grey colour. This colour is achieved by sprinkling the cheese with ash, which is a traditional practice in France's Loire Valley. The ash gives the cheese a foggy or cloudy grey appearance, and it is often used in combination with a yeast called geotrichum candidum, which gives the cheese a sweet and mellow flavour.
Grey Owl, produced by Fromagerie Le Détour in Quebec, is a popular example of an ash-covered goat cheese. It is a surface-ripened cheese with a dense paste that becomes creamy and runny at the edges as it ages. Its flavour is described as pleasantly lemony, and it is commonly paired with honey, citrus, and white wine. Another example of a grey goat cheese is Amazing Grey, a farmstead Parmesan produced by Stonetown Artisan Cheese in Ontario. This cheese is known for its natural sweet flavour and contrasting texture between the aromatic rind and the interior.
The addition of ash not only affects the colour of the cheese but also influences its flavour and texture. The ash can interact with the cheese's natural rind, promoting the development of certain bacteria and moulds that contribute to the cheese's unique characteristics. The amount of ash used, the type of ash, and the ageing process can all impact the final flavour and texture of the cheese. Thus, sprinkling ash on goat cheese not only gives it a distinct grey colour but also enhances its sensory experience.

Frequently asked questions
Goat cheese is predominantly white or off-white, though its exact shade may vary.
The color of goat cheese is influenced by the color of the milk it is made from. Goat's milk contains less beta-carotene than cow's milk, resulting in a whiter cheese.
Beta-carotene is a natural pigment found in plants, especially those with deep orange or yellow hues, such as carrots and grass. Cows consume these plants as part of their diet, and the pigment is absorbed into their bloodstream and excreted in their milk, giving it a yellow tint.
No, while most goat cheeses are white, some goat cheeses, like the French Loire Valley's Bonne Bouche, are grey due to the use of ash. Others, like the Spanish Drunken Goat, have a white interior and a violet rind from being washed in red wine.
Yes, the color difference between goat and cow cheese is due to variations in the animals' diets and how they process beta-carotene. Cows' milk-producing glands accumulate beta-carotene, tinting their milk yellow, while goats fully digest and convert it into colorless vitamin A, resulting in white milk and cheese.
