How to identify mould on cheddar cheese
Mould on cheddar cheese can be identified by white, wispy dots or a fuzzy coat on the surface. This mould is typically harmless but may compromise the taste of the cheese. It is important to distinguish between mould and crystals, which are a sign of well-aged cheese. Crystals are hard and crunchy, while mould is soft and powdery.
If you find mould on your cheddar cheese, it is generally recommended to cut off the affected portion and discard it. The depth of mould penetration depends on the moisture level of the cheese, with drier cheeses like long-aged cheddar having minimal penetration. However, it is crucial to exercise caution, as some mould types, such as dark black-grey Aspergillus niger, can be harmful.
To prevent mould growth on cheddar cheese, proper storage is essential. Wrap the cheese in special cheese paper or parchment paper and store it in the crisper drawer of your refrigerator. Alternatively, a dedicated wine fridge can provide a less cold and more suitable environment for cheese storage.
Additionally, consuming cheese within a reasonable timeframe can help prevent mould issues. Aged cheddars that are 18 months or older are less likely to develop mould. While mould on cheese is usually not harmful, it can alter the flavour and texture, so it is advisable to cut off the mouldy portion before consumption.
In summary, mould on cheddar cheese can be identified by visible surface changes and textural differences between mould and crystals. Proper storage, timely consumption, and cutting off affected portions are recommended to manage mould growth and maintain the quality of cheddar cheese.

What to do if you find mould on cheddar cheese
Mould on cheddar cheese is not uncommon, and it is natural to wonder what to do in such situations. Here are some detailed instructions on what to do if you find mould on your block of cheddar cheese:
First, assess the type of cheese. Cheddar is generally considered a hard, aged cheese, but a mild or semi-soft variety may be more susceptible to mould. If you have a softer variety of cheddar, it is recommended to discard the cheese entirely as the mould will likely have penetrated deeper into the cheese, altering its flavour and texture.
If you have a hard, aged cheddar, you can simply cut off the mouldy part. Mould tends to grow roots, similar to houseplants, and the visible fuzz may have tendrils that extend into the cheese. However, microorganisms that cause mould thrive in moist environments, so they will generally not penetrate as deeply into hard, dry cheeses like aged cheddar.
When cutting off the mould, examine the cheese to determine how far the roots have grown, and cut generously to ensure that all the roots are removed. The cheese will be safe to eat after the mouldy section has been cut off, but the flavour may be slightly altered in the surrounding area.
It is important to note that while most mould on cheese is not dangerous, there are some rare types of mould that you should watch out for. For example, dark black-grey mould, such as Aspergillus niger, is not commonly found on cheese, but it may indicate the presence of toxins. If you encounter mould that appears to be black-grey in colour, it is best to discard the entire block of cheese to avoid any potential health risks.
To prevent mould from growing on your cheddar cheese, proper storage is essential. Wrap the cheese in special cheese paper or parchment paper and store it in your refrigerator's crisper drawer, which provides a consistent temperature and humidity level. Alternatively, if you have a wine fridge, you can store your cheese there, as the slightly higher temperature is actually better for the cheese and can help prevent mould.

How to prevent mould on cheddar cheese
Cheddar cheese is susceptible to mould growth, especially when exposed to oxygen. To prevent mould on cheddar cheese, it is essential to store the cheese properly. Here are some tips to prevent mould:
Store cheddar cheese in an airtight container:
To prevent mould growth, cheddar cheese should be tightly wrapped in an airtight material, such as plastic wrap or special cheese paper. This minimises exposure to air, which can cause the cheese to dry out and become more susceptible to mould.
Keep cheddar cheese in a controlled environment:
Store cheddar cheese in a dedicated drawer, such as a crisper drawer, that maintains a consistent temperature and humidity level. Alternatively, a wine fridge can be used, as the slightly higher temperature is better for the cheese.
Buy long-aged cheddar cheese:
Older cheddars that have been aged for 18 months or longer are less likely to develop mould. These long-aged cheddars are harder and drier, making it difficult for mould to penetrate the surface.
Practice good hygiene when handling cheddar cheese:
Even with thorough hand washing, trace amounts of bacteria can be transferred to the cheese, encouraging mould growth. To avoid this, use gloves or ensure that the packaging creates a barrier between your hands and the cheese.
Consume cheddar cheese within a reasonable timeframe:
Eat cheddar cheese within a reasonable period to prevent mould growth. Mould can develop when cheese is left for an extended period, especially in moist environments where microorganisms thrive.

The different types of mould that can grow on cheddar cheese
Mould is an integral part of the cheesemaking process, and it is what gives the finished cheese its flavour and texture. However, mould that grows on cheese stored in a refrigerator may compromise the cheese's taste.
Mild cheddar and other semi-soft cheeses are more susceptible to mould growth than long-aged, crumbly cheddars. This is because microorganisms that cause mould thrive in moist environments. Therefore, mould roots can penetrate deep into semi-soft cheeses, whereas they will barely be able to penetrate the surface of long-aged cheddars.
There are a few types of mould that are rare to find on cheese, such as the dark black-grey mould Aspergillus niger. However, most moulds are harmless and will not hurt you. Nevertheless, it is not advisable to eat mouldy cheese, as it will not taste the same as intended.
If you encounter mould on your cheddar cheese, you can simply cut off the mouldy part and consume the rest of the cheese. To prevent mould from growing on your cheese, it is important to store it properly and consume it within a reasonable timeframe. Wrap the cheese in special cheese paper or parchment paper and store it in your crisper drawer, which provides a consistent temperature and humidity. Alternatively, you can store cheese in a wine fridge, where the temperatures are less cold and better suited for cheese storage.

The safety of consuming mouldy cheddar cheese
Mouldy cheddar cheese can be consumed in some cases, but it is not always safe and depends on several factors. Firstly, the type of mould present is crucial. While most moulds are not harmful, certain types like the dark black-grey mould Aspergillus niger can be toxic. Therefore, it is important to identify the mould and exercise caution if it is not a common cheese mould.
Secondly, the extent of mould growth matters. Mould grows like roots and can penetrate deeper into softer, moister cheeses. In the case of mild or semi-soft cheddars, the mould roots can spread further, potentially affecting more of the cheese. On the other hand, mould has difficulty penetrating the surface of hard, aged cheddars, and scraping it off is usually sufficient to make the cheese safe for consumption.
Additionally, proper storage and timely consumption of cheese are essential to prevent mould. Wrapping cheese in special cheese paper or parchment paper and storing it in a consistent temperature and humidity environment, like a crisper drawer or wine fridge, can help inhibit mould growth. Aged cheddars that are 18 months or older are also less prone to mould.
Lastly, personal preference plays a role. Even if the mould is scraped off, the affected area of the cheese may not taste as intended. Some people may find the altered flavour unappealing and choose not to consume it. In summary, consuming mouldy cheddar cheese can be safe under certain conditions, but it is always advisable to exercise caution and assess the situation before eating any mould-affected food.
