The Art Of Cheese Aging: Time To Perfection

The length of time required to mature cheese depends on several factors, including the type of cheese, the environment, and the desired flavour and texture. Cheese can be aged for as little as a few weeks or for several years. For instance, 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. Fresh cheeses like cream cheese, ricotta, and cottage cheese are highly perishable and do not require extended aging, while firmer cheeses like cheddar, gouda, and parmesan benefit from longer aging periods to develop their distinct flavours and textures. The aging process involves ripening the cheese to break down its components, including milk proteins, milk fat, and lactose, resulting in the desired flavour and texture.

Hard cheeses like Cheddar, Parmesan and Gouda can last for a year unopened

Hard cheeses, such as Cheddar, Parmesan, and Gouda, are aged for longer periods and have a lower moisture content, which helps extend their shelf life. These cheeses are made by removing most of the whey from the curds during the cheesemaking process, which removes a lot of the moisture. They are then either brined to create a hard rind or waxed and aged for between two and 36 months, and sometimes even longer.

Hard cheeses that haven't been opened can last for several months and even up to a year when stored in a refrigerator. Unopened blocks of hard cheese can last for 6 months in the fridge. Once opened, hard cheeses can last for a few weeks to a couple of months in the refrigerator. It is important to store hard cheeses in an airtight container or wrapped tightly in the coldest part of the fridge.

Hard cheeses can be left out of the fridge for longer than soft cheeses without becoming unsafe, but the quality and taste may change. Hard cheeses can be left out for up to 4 hours, but it is still important to check for signs of spoilage. Spoiled hard cheeses may display an unpleasant smell, a slimy surface, dark spots, dryness, cracks, or mould. White specks or crystallized patches on certain aged hard cheeses are normal and safe to eat. These spots are most likely not mould but calcium lactate crystals, which form when the lactic acid in cheese combines with calcium.

Blue cheeses like Stilton, Roquefort and Gorgonzola can last unopened for several months

Blue cheeses, such as Stilton, Roquefort, and Gorgonzola, are made using a type of mould called Penicillium, which is responsible for their distinct taste, smell, and appearance. Unlike other types of mould, the varieties of Penicillium used to produce blue cheese do not produce toxins and are safe to consume.

The ageing process for blue cheese typically lasts for 2-3 months. During this time, the cheese loses moisture, resulting in a harder and firmer texture compared to young, fresh cheese. The longer the ageing process, the sharper and more intense the flavour becomes.

Unopened blue cheeses can last for several months in the fridge, depending on the humidity and temperature. If stored properly, blue cheese can have an extended shelf life. Freezing blue cheese can also help to prolong its shelf life, although this may slightly alter its texture and appearance.

It is important to note that blue cheese can go bad if not stored properly. It should be tightly wrapped and refrigerated, and even then, it will only last 3-4 weeks. If there are signs of spoilage, such as fuzzy white, green, pink, or grey spots, or a strong ammonia-like smell, the cheese should be discarded.

Soft cheeses like Brie and Camembert have a shelf life of a few weeks to a couple of months unopened

Soft cheeses like Brie and Camembert are crafted with meticulous craftsmanship, reflecting the rich cheesemaking traditions of France. These indulgent cheeses boast a creamy texture and a distinctive white rind, with Brie offering a milder, buttery aroma and Camembert presenting a bolder, earthier flavour profile.

When it comes to maturation, Brie and Camembert have different timelines. Brie undergoes a lengthier ageing process, typically maturing for four to eight weeks, while Camembert has a shorter maturation period, usually around three weeks. This variation in ageing time imparts distinct textures to the cheeses, with Brie retaining its softer, gooey texture and Camembert developing a slightly firmer consistency.

To ensure optimal ripeness, soft cheeses like Brie and Camembert benefit from being stored in their original wooden boxes. These boxes create a humid environment that promotes ideal maturation conditions. It is recommended to open each box and gently squeeze the cheese to assess its ripeness, as batch codes or best-before dates may not always provide an accurate indication. Sorting the cheeses by ripeness allows retailers to cater to varying customer preferences.

The maturation environment also plays a crucial role in developing the desired texture and flavour of soft cheeses. Maintaining a temperature of around 6-8°C is ideal for promoting the maturation of Brie and Camembert, although lower temperatures can be utilised to slow down the process and extend the shelf life of the cheeses.

In summary, soft cheeses like Brie and Camembert have a shelf life of a few weeks to a couple of months when unopened. This maturation period allows their flavours to evolve and intensify, transforming them from fresh cheeses into complex, matured products with distinct textures and aromas.

Fresh cheeses like cream cheese, ricotta and cottage cheese last for a few weeks past their 'best by' date

Fresh cheeses like cream cheese, ricotta, and cottage cheese are not aged and have a mild, soft, and creamy flavor. They tend to be more watery and are highly perishable. Generally, soft cheeses will last for about one week in the fridge, but their quality and taste will start to decline before that time is up.

Cream cheese, for example, will develop a sour flavor and cracked texture if it is aged. It is best to avoid aging this type of cheese. Fresh cream cheese has a soft, rich, and smooth flavor that is easy to spread and is therefore widely popular.

Ricotta cheese is affordable and widely available. It is typically made from a mixture of whole, skim, or low-fat cow's milk and whey. It has a grainy texture and tends to be lower in fat compared to other cheeses. It is often used in dishes like vegetables, eggs, toast, and pasta.

Cottage cheese is another example of a fresh cheese that does not require aging. It is also highly perishable and should be discarded if mold is present.

To extend the shelf life of fresh cheeses, proper storage is key. Fresh cheeses should be wrapped in wax, parchment, or cheese paper and stored in the top or middle shelf of the fridge, or in a drawer. They should be kept above raw meats, poultry, and fish to avoid contamination. The ideal temperature for storing cheese is below 40°F (4°C).

Fresh cheeses like cream cheese, ricotta, and cottage cheese will generally last for a few weeks past their best-by date if stored properly.

Opened hard cheeses can last a few weeks to a couple of months

The shelf life of cheese varies depending on the type of cheese and whether it is opened or unopened. Opened hard cheeses, such as Cheddar, Gouda and Parmesan, can last for a few weeks to a couple of months in the refrigerator. To maximise their lifespan, they should be stored in an airtight container or wrapped tightly in the coldest part of the fridge.

Hard cheeses that haven't been opened can last for several months and even up to a year when stored in the fridge. This is because they have a lower moisture content, which helps extend their shelf life.

The length of time that cheese can be stored also depends on how it has been treated prior to packaging. For example, waxed cheeses should be stored in the fridge to avoid the cheese swelling and cracking the wax.

Once opened, exposure to air and potential bacterial contamination means that the shelf life of cheese will decline considerably. Soft cheeses are more perishable than hard cheeses and typically last for about a week to a few weeks in the refrigerator. Fresh cheeses such as ricotta and cottage cheese have an even shorter shelf life and are best consumed within one to two weeks of opening.
