The Art Of Cheese Making: Maturation Time Explored

The maturation time of cheese depends on the type of cheese and the desired quality. Fresh cheeses have little to no maturation time, soft cheeses are usually matured for between two weeks and two months, and hard cheeses are matured for a few months up to two years or more. For example, mild cheddar is matured for two to three months, while extra sharp cheddar is matured for 18 months to two years or more. The maturation process is important as it gives cheese its distinct flavour and texture.

The length of time varies depending on the type of cheese

The length of time cheese takes to mature depends on the type of cheese. While some cheeses are made to be eaten fresh, others are designed to be cured in a controlled environment for an extended period.

Fresh cheeses, such as cream cheese, farmer's cheese, cottage cheese, and ricotta, typically have little to no aging time. These cheeses are usually soft, spreadable, rindless, unripened, and white in colour. They tend to be more watery and have a mild, soft, or creamy flavour.

On the other hand, aged cheeses are stored in a cool, controlled environment to mature for a certain period. They are generally harder and sharper in texture, giving them a more rich, complex, and concentrated flavour. Their firm, compact nature allows them to be shaved, sprinkled, or grated over vegetables, salads, and pasta dishes.

Aged cheeses can be further categorised into soft cheeses and hard cheeses. Soft cheeses, such as Muenster or mild cheddar, typically have shorter aging times, ranging from a few weeks to a few months. In contrast, hard or semi-hard cheeses like sharp cheddar, Swiss, or Parmesan require longer aging periods, usually starting at a few months and spanning up to two years or more.

The aging time also varies within specific types of cheese. For example, mild cheddar is typically aged for 2 to 3 months, while extra sharp cheddar may be aged for 18 months to 2 years or more. Similarly, Gouda can range from young to very aged, with aging times ranging from a month to over a year.

The aging process is crucial in developing the signature characteristics of a particular cheese. It allows time for microbes and enzymes to break down proteins and fats, influencing the texture, taste, and aroma of the cheese. A longer aging time generally results in a firmer and more intense cheese, while shorter aging times produce a milder taste and softer texture.

The process is known as ripening or maturing

The process of ripening or maturing is known to give cheese its distinct flavour and texture. It involves a series of complex physical, chemical, and microbiological changes that occur over time, with the help of bacteria and enzymes.

During ripening, the cheese's proteins break down into amino acid compounds in a process called proteolysis, which gives certain cheeses fruity, nutty, or smoky flavours. This process also changes the texture of the cheese, forming crunch crystals, or tyrosine, in certain aged cheeses.

The ripening process is influenced by a variety of factors, including the type of cheese, the desired quality, microflora, and the curd. The most important agents in this process are rennet, starter bacteria and associated enzymes, second starter bacteria and associated enzymes, and non-starter bacteria.

The duration of the ripening process depends on the type of cheese and the desired quality, typically ranging from three weeks to two or more years. Fresh cheeses often have little to no ageing time, soft cheeses are usually aged for between two weeks and two months, and hard cheeses have longer ageing periods, starting at a few months and spanning up to two years or more.

The environment in which the cheese is ripened is also crucial to the process. While cellars and caves were traditionally used, modern cheesemakers use temperature- and humidity-controlled environments to carefully manage the growth of surface mould and mould ripening by fungi.

It's important for developing the cheese's signature taste, texture and aroma

The maturation of cheese is a crucial process in developing the signature taste, texture and aroma of the final product.

During maturation, millions of microbes and enzymes break down proteins and fats into a complex combination of acids that influence the expression of texture, taste and aroma in the cheese. A longer maturation time results in a firmer, more intense cheese, while a shorter maturation time yields a milder taste and softer texture.

The process also allows for the development of mould rind bloom, the opening of 'eyes' to create holes, and the branching out of blue veins. The maturation time will vary depending on the type of cheese and the desired quality, ranging from three weeks to two or more years.

For example, soft cheeses are usually matured for between two weeks and two months, while hard cheeses are matured for longer periods, starting at a few months and spanning out to two years or more.

The maturation process also differs depending on whether the cheese is surface-ripened, like Blue Cheese, which ripens from the surface inwards, or an interior-ripened cheese like Cheddar, which ripens from the middle outwards to the surface.

The environment in which the cheese is stored is key to the process

The environment in which cheese is stored is key to the maturation process. While in the past, cellars and caves were used to ripen cheeses, today, the process is highly industrialised and involves machinery and biochemistry. However, the fundamental principles remain the same.

The temperature and humidity of the environment are crucial factors in the maturation process. Most cheeses are aged somewhere between 7° and 14° Celsius. Maintaining the correct and consistent temperatures is essential, as temperatures outside this range can cause the cheese to dry out or fail to mature properly. Similarly, humidity levels that are too low can cause the cheese to dry out, while too much humidity can attract unwanted moulds or cause other undesirable effects. Ideal humidity levels range from 75% to 95%, depending on the type of cheese being matured.

Air circulation is another important consideration. Constant, low-flow air circulation supports the exchange of gases (oxygen, carbon dioxide, and gases emitted from the cheeses) necessary for the proper development of the cheese. However, too much air movement will draw moisture from the cheese, causing the surface to crack and the cheese to dry out. Spacing the cheeses well and ensuring the environment is not overcrowded can help achieve appropriate air flow.

The maturation environment must also be carefully monitored and maintained to prevent the growth of undesirable moulds, which can not only ruin the cheese but also spread to other cheeses and potentially cause health risks. Regularly checking the temperature, humidity, and ventilation, as well as inspecting the cheese for unwanted moulds, is crucial to ensuring a successful maturation process.

By controlling these environmental factors, cheesemakers can influence the texture, taste, and aroma of the cheese, creating the desired characteristics for each variety.

The longer the cheese is aged, the less lactose is present

Cheese is made from the same core ingredients, but the aging process creates thousands of varieties by changing the flavour and texture of the product. The aging process, also known as ripening, is responsible for the distinct flavour of cheese. The longer the cheese is aged, the more intense the flavour.

The aging process involves a series of complex physical, chemical, and microbiological changes. The cheese is taken through a series of maturation stages where temperature and relative humidity are carefully controlled, and the surface mould is allowed to grow. The growth of mould and bacteria breaks down the lactose in the cheese, turning it into lactic acid.

The longer the cheese is aged, the more time the bacteria have to break down the lactose, which is why aged cheeses have very low levels of lactose. This is good news for people who are lactose intolerant, as they may still be able to consume aged cheeses without experiencing any symptoms.

The aging process also affects the texture of the cheese. Softer cheeses like mild cheddar take a shorter amount of time to age, whereas semi-hard and hard cheeses like sharp cheddar or parmesan require a longer period to develop their desired texture, flavour, and aroma.
