Cheese Varieties: Cow Milk's Versatile Transformation

Cheese is made from different types of milk, including cow's milk, sheep's milk, goat's milk, and buffalo milk. Cow's milk is the most common type used for cheesemaking due to its wide availability and optimal fat and protein content. It is used to make popular cheeses such as Swiss, cheddar, and Gouda. The type of milk used plays a crucial role in determining the distinct flavours and textures of different cheeses.

Different breeds of cows produce different types of cheese

Cow's milk is used to make a wide variety of cheeses, from soft to hard, including cheddar, gouda, Alpine-style cheese, and mozzarella. Different breeds of cows produce different types of cheese. This is because various breeds yield milk with different compositions, which affects the flavour and texture of the cheese.

Breeds such as Dairy Shorthorn, Gloucester, and Ayrshire, which are native to the UK, produce milk with a helpful protein-to-fat ratio and small fat globules that are easier to incorporate into the cheese curd. The Ayrshire breed, in particular, is known for its hardy nature, making it well-suited to rugged terrain and adverse conditions. Their milk gives cheese a soft, buttery-rich flavour and a round mouthfeel.

On the other hand, the Holstein-Friesian breed, which comprises about 90% of the dairy population in Britain, produces a high volume of milk but is not known for its ideal quality. Their milk has larger fat globules that can be too rich for cheesemaking, causing them to settle out too quickly. As a result, this breed is more commonly used for liquid milk and cream.

In Europe, certain cheeses are made according to strict rules that stipulate the exact breed of cow that must be used. For example, Comté cheese must be made from Montbéliarde or Simmental cows' milk, while Salers Tradition cheese must come from Salers cattle. Parmigiano Reggiano, or "red cow" Parmesan, is made from the milk of Italian red cows (vacche rosse), and is considered a premium version of the cheese.

The breed of cow is particularly important for farmhouse cheesemakers, who use milk from a single herd. The unique characteristics of the milk from each breed can help create a cheese that is distinct to a particular farm or region, showcasing the terroir of the land.

Cows' milk is widely used due to its optimal fat and protein content

Cow's milk is widely used in cheese-making due to its optimal fat and protein content. The milk of bovines, which includes cows, makes up about 83% of the milk and dairy consumed by humans globally. This is because cows produce a large volume of milk, and their milk has a higher fat and protein content than other species.

The fat and protein content of cow's milk is important for cheesemaking. Fat and protein are two of the key components in milk, along with water, sugar (lactose), minerals, and enzymes. The goal of cheesemaking is to preserve these components, except for water, which is removed to preserve the milk. The fat and protein content of milk varies depending on the breed of cow, and cheesemakers will select cows with a higher fat and protein content to make their cheese. For example, Normande and Ayrshire cows are often chosen for cheesemaking because they produce milk with high fat and protein content in nearly equal amounts.

The fat and protein content of the milk also determines the type of cheese that can be made. Milk with a fat content of at least 3.25% is suitable for cheesemaking, although unhomogenised milk with a higher fat content is preferred. Skimmed milk, lite milk, and UHT milk are not suitable for cheesemaking, as they will not set into curds. Additionally, milk with a higher fat content is also richer and creamier in taste, which is desirable for cheese.

The breed of cow is also important for cheesemaking, as different breeds produce milk with varying fat and protein contents. For example, Jersey cows produce milk with a higher fat content than Holstein cows, which is why they are favoured by cheesemakers. The diet of the cow can also impact the fat and protein content of the milk, as cows that are grass-fed will impart flavours of the pasture into their milk.

Milk from Jersey cows is richer and creamier than milk from Holsteins

Milk from Jersey cows is indeed richer and creamier than milk from Holsteins. This is because Jersey milk has a higher butterfat content, at 4.7% compared to 3.7% for Holsteins. This makes Jersey milk more profitable, despite Holsteins producing more milk overall.

Jersey cows are one of the oldest breeds of cattle, originating on the Island of Jersey in the English Channel. They are the smallest of all dairy cow breeds, weighing about 1,000 pounds and standing 48 inches tall. In comparison, Holsteins are the largest dairy breed, weighing up to 1,500 pounds and standing 58 inches tall.

Jersey cows are also more efficient at converting feed into milk. They produce around 17 times their body weight in milk each lactation, or roughly 6 gallons of butterfat milk per day. Holsteins, on the other hand, produce about 9 gallons of milk per day, but this comes at a higher feed cost.

The higher butterfat content of Jersey milk is also linked to better health outcomes. Studies have shown that people who drink raw milk with a high percentage of butterfat have lower central obesity. Additionally, Jersey milk is more suitable for people with lactose intolerance, as it predominantly contains A2 beta-casein protein, which is easier to digest than the A1 beta-casein found in Holstein milk.

In terms of temperament, Jersey cows are curious and friendly, while Holsteins are known for being easygoing. The unique patterning of their coats also makes Holsteins visually distinctive, with a black and white or red and white coat. Jerseys, on the other hand, range from light brown to dark brown with black hooves and a distinctive "dish"-shaped face.

Milk from different cows will have different colours, e.g. Jersey milk is yellowish, Holstein milk is pure white

Milk from different cows will have different colours, and this is influenced by both genetics and diet. Jersey milk is yellowish, while Holstein milk is pure white. This is due to the amount of butterfat in the milk, which is linked to the levels of beta carotene and xanthophylls.

Jersey cows produce milk with a butterfat content of 5.2% to 5.3%, which is higher than that of Holstein cows, whose milk has a butterfat content of 3.4%. Beta carotene and xanthophylls are substances found in fat, and they give plants their colour. They are absorbed by cows from the grass, vegetables, and other plant materials they eat. As Jersey cows have a higher percentage of fat in their milk, there are also higher levels of beta carotene and xanthophyll, making the milk yellow.

The diet of the cows also affects the colour of their milk. Cows that graze on grass pastures tend to produce yellower milk than those fed commercial food. In the winter, when grass is scarce, cows may be given hay or silage, which can also affect the colour of the milk. Silage tends to contain higher levels of carotenoids than hay.

The colour of milk is not the only difference between Jersey and Holstein cows. Jersey cows are smaller and produce less milk than Holstein cows, but their milk has a higher content of fat and protein, which directly affects the farmer's income. Jersey cows are also known for their friendly temperament and ease of handling, making them a popular choice for dairy farmers.

Cows' milk is used to make Swiss, cheddar, gouda, mozzarella, and more

Cows' milk is used to make a wide variety of cheeses, including Swiss, cheddar, gouda, mozzarella, and many more. In fact, most cheeses are made using cows' milk due to its wide availability and optimal fat and protein content.

Swiss cheese, for example, is a type of interior-ripened cheese, known for its distinct flavour and aroma that develop during the aging process. Similarly, cheddar cheese also undergoes an aging process, resulting in a crumbly texture and sharp flavour. Cheddar is a popular variety that is widely produced and consumed, with variations such as the Isle of Mull Cheddar and Lincolnshire Poacher cheese.

Gouda, another cow's milk cheese, is known for its firm texture, enriched flavours, and caramel undertones after aging. Gouda is a washed curd cheese, which contributes to its mild flavour and elastic texture.

Mozzarella, while traditionally made with buffalo milk, is most commonly produced using cows' milk in mass-produced varieties. It is a stretch-cured cheese, where the curds are submerged in hot water and stretched, resulting in a pliable texture.

In addition to these well-known varieties, cows' milk is used to make numerous other cheeses, such as Abbaye de Timadeuc, Ardrahan Farmhouse Cheese, Cahill's Farm Cheese, and Carrigaline Farmhouse Cheese, to name a few. The versatility of cows' milk in cheesemaking allows for a diverse range of flavours, textures, and types of cheese to be created.
