The sharpness of cheddar cheese is a highly debated topic, with the term sharp being controversial and complex. The sharpness of cheddar refers to the changes in taste and texture that occur during the aging process, which can range from two months to several years. The aging process causes cheddar to lose moisture, resulting in a firmer texture with hard, salt-like crystals. While the term sharp is commonly used to describe the intensity of flavour in cheddar, it is important to note that sharpness is subjective, and cheese enthusiasts may have different opinions on what constitutes a sharp cheddar. The sharpness of cheddar can vary depending on factors such as ageing time, texture, and the development of distinct flavours.

What You'll Learn
The longer the aging, the sharper the cheddar
The sharpness of cheddar cheese is determined by the length of time it is aged. The longer the cheese is aged, the sharper and more robust its flavour becomes. This occurs as the cheese loses moisture during the ageing process, resulting in a stronger taste.
Cheddar cheese is a versatile staple in kitchens around the world, with its unique flavour and texture. The process of ageing cheddar is called "cheddaring". To create cheddar cheese, the liquid is first strained from the curds, and the curds are then cut into slabs, stacked, and flipped to release more liquid. The dense curds are then pressed into moulds and aged.
The length of the ageing process determines the sharpness and complexity of cheddar's flavour. Young cheddar, aged for a few months, has a mild and creamy taste. As it ages, cheddar becomes sharper and nuttier in flavour. Properly sharp, mature cheddar is usually aged for at least a year. However, some cheddars are aged for much longer, with some reporting cheddars aged for up to 10 or even 15 years!
The ageing process also affects the texture of the cheese, with older cheddars developing a crumbly texture due to the formation of hard, salt-like crystals. These crystals are composed of an amino acid called tyrosine. Aged cheddars also offer several benefits, including reduced lactose content, making them more tolerable for lactose-intolerant individuals, and a higher concentration of nutrients such as protein, calcium, and vitamin A.

The term sharp refers to the changes in taste and texture
The term "sharp" in the context of cheese refers to the changes in taste and texture that occur during the aging process. The aging process is what gives each variety of cheese its distinctive flavour and texture. The longer a cheddar cheese ages, the sharper it gets. The aging process involves the breakdown of lactose in the cheese into lactic acid, which lowers the pH and results in a tangy, nutty, sour, or acidic taste. This process also causes the cheese to lose moisture, leading to a change in texture from smooth and creamy to firm and crumbly, with hard, salt-like crystals.
The term "sharp" is commonly used to describe the intensity of flavour in cheddar cheese, with a sharp cheese having a more concentrated and intense flavour. The aging process also affects the texture of the cheese, making it drier and more brittle. The crystals that form on aged cheeses are called tyrosine, an amino acid.
The aging process for cheddar cheese typically takes anywhere from two months to a year or more, depending on the desired sharpness. The minimum aging time for a cheddar to be considered sharp is six months, and extra sharp cheddars are aged for more than 18 months. The aging process is a gamble for cheese producers, as it involves a significant investment of time and resources, and there is always a temptation to get the cheese out the door faster.
The term "sharp" is often used as a marketing term for factory-produced cheddars, and it has been argued that it does not accurately describe the flavour profile of cheese. Instead, it may be used as a catch-all term for intensity, acidity, or sourness. When choosing a sharp cheddar, it may be more reliable to look for an "aged" cheddar, as this guarantees a minimum aging period and, therefore, a more intense flavour.

Cheddar undergoes a process called proteolysis
The sharpness of cheddar cheese is determined by the aging process, which can take anywhere from two months to over 18 months, or even several years. During this time, the cheese undergoes a series of changes that affect its flavour and texture. One of the key processes that occur during aging is proteolysis, a reaction in which proteins break down into smaller peptides and individual amino acid residues.
Proteolysis plays a crucial role in developing the sharp flavour and crumbly texture of aged cheddar. As the cheese ages, enzymes break down the proteins and fats present in the cheese through proteolysis and lipolysis. This breakdown results in the formation of shorter protein chains and free amino acids, which contribute to the umami taste and the crunchy crystals characteristic of aged cheddar. The crystals in younger cheeses are composed of calcium lactate, while those in highly aged cheeses are composed of tyrosine, an amino acid.
In addition to its effects on flavour and texture, proteolysis also has therapeutic potential. Studies have shown that bioactive peptides derived from cheddar cheese through proteolysis can exhibit antioxidant, anti-thrombotic, antihypertensive, opioid, antibacterial, and immunomodulatory properties. The use of probiotic adjuncts, in combination with mesophilic starter cultures, enhances the production of these bioactive peptides.
The process of proteolysis is influenced by various factors, including moisture content, manufacturing technology, ripening time, temperature, and cheese composition. These factors, along with different processing techniques and time-temperature variations, contribute to the overall character and quality of aged cheddar cheese.

The aging process affects the flavour and texture of cheese
The aging process is key to developing the flavour and texture of cheese. All cheeses contain the same basic ingredients: milk, enzymes, salt, and bacterial culture. However, the aging process transforms these simple ingredients into a symphony of flavours and textures.
The term "sharp" in cheese refers to the changes in taste and texture that occur as the cheese ages. The longer a cheese is aged, the sharper it gets. Mild cheddar is aged for about three months, sharp cheddar for about nine months, and extra sharp cheddar for more than 18 months. During the aging process, cheddar loses moisture, transforming from smooth and creamy to firm with hard, salt-like crystals. These crystals are called calcium lactate in younger cheeses and Tyrosine in older cheeses.
The aging process also affects the flavour of cheese. As cheese ages, the culture inside the curd breaks down the lactose in the cheese, turning it into lactic acid. This process gives aged cheese its distinctive smoky, fruity, or nutty flavours. The breakdown of lactose also affects the texture of the cheese, making it firmer and more crumbly.
The local environment, including factors such as temperature and humidity, also play a role in the aging process. This is known as "terroir" in French. For example, the unique blue veins in Roquefort cheese are created by aging the cheese in specific caves in the Roquefort region of France, where a special mold called Penicillium Roquefort grows.
In addition to flavour and texture, the aging process also affects the nutritional content of cheese. Longer aging allows the cheese to concentrate its beneficial nutrients, such as protein and calcium.

Mild cheddar is aged for 3 months, sharp for 9 months, and extra sharp for 18+ months
The sharpness of cheddar cheese is determined by the length of time it has been aged. Mild cheddar is aged for the shortest amount of time, typically around three months, and has a creamy, subtle, and smooth texture with a relatively high moisture content. It is easy to slice and melts well, making it a great option for grilled cheese sandwiches or as an ingredient in dishes such as macaroni and cheese.
Sharp cheddar, on the other hand, is aged for a longer period, usually around nine months. During the aging process, cheddar loses some of its moisture, resulting in a firmer texture with hard, salt-like crystals. This longer aging period gives sharp cheddar a tangier, nuttier, and more robust flavour than mild cheddar.
Extra-sharp cheddar takes it a step further, with an aging process of 18 months or more. This extended aging gives it an even bolder flavour and a distinct, crumbly texture. The longer aging period also results in a lower moisture content, which makes extra-sharp cheddar ideal for eating out of hand but less suitable for melting.
The aging process not only affects the sharpness and texture of the cheese but also influences its complexity of flavours and nutritional content. Aged cheddar often contains fewer lactose molecules, making it more suitable for those with lactose intolerance. Additionally, the aging process increases the concentration of nutrients such as protein, calcium, and vitamin A.
When comparing the sharpness of cheddars, it is best to choose two products of the same brand with different aging times. This ensures that any differences in taste and texture are due to aging rather than variations in ingredients or production methods.
