Blue Cheese: How Long Does It Last?

Blue cheese is a pungent, edible mould cheese with a distinct smell and flavour. It is made using cultures of Penicillium, a type of mould. Unlike other moulds, the Penicillium used in blue cheese does not produce toxins and is safe to consume. However, blue cheese can still go bad, so it is important to store it properly. When stored properly in the refrigerator, blue cheese can last anywhere from 3-4 weeks to 1-2 months. To extend its shelf life, it can be frozen for up to 6 months, although this may alter its texture and appearance.

Blue cheese can last 3-4 weeks in the fridge

Blue cheese is a pungent, edible mould that has a distinct smell and taste. It is a popular ingredient in many dishes, from salads to sauces. But how long does it last in the fridge?

Well, blue cheese can last 3-4 weeks in the refrigerator if stored properly. To ensure maximum freshness, it is recommended to wrap the cheese first in wax or parchment paper and then in plastic wrap or aluminium foil. This will help keep the cheese from drying out. It is also important to note that the refrigerator temperature should be set below 40 degrees Fahrenheit.

Blue cheese can also be frozen to extend its shelf life. When freezing, cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap. Frozen blue cheese can last for about six months but may lose some of its sharp flavour and become crumbly.

It is important to note that blue cheese can go bad if not stored properly. Signs that blue cheese has spoiled include a change in smell (an ammonia-like smell), a change in colour (pink, brown, or green), or the presence of a slimy or fuzzy texture. If you notice any of these signs, it is best to discard the cheese.

It can be frozen to extend its shelf life

Blue cheese can be frozen to extend its shelf life. If you're not planning to use your blue cheese within a month, freezing is a great option to prevent it from spoiling. It can be kept in the freezer indefinitely, although for the best taste and texture, it's recommended to consume it within six months.

When freezing blue cheese, it's important to cut it into portions no larger than half a pound each. For crumbled blue cheese, divide it into portions of similar weight. Wrap the cheese tightly in heavy-duty aluminium foil or plastic freezer wrap, or place it inside a heavy-duty freezer bag.

Freezing may slightly alter the texture and appearance of blue cheese, making it crumbly and less sharp in flavour. Therefore, it's best suited for cooked dishes such as sauces, soups, and casseroles.

It's also important to note that frozen blue cheese should not be refrozen after thawing. If you plan to thaw it in the refrigerator, it can be kept for an additional 3 to 4 days before using. If you thaw it in the microwave or in cold water, it should be used immediately.

It's spoiled if it smells like ammonia

Blue cheese is a type of cheese that is known for its strong smell and flavour. It is made using a type of mould called Penicillium, which is added during the cheesemaking process and is responsible for the distinct taste, smell, and appearance of blue cheese. While blue cheese is safe to eat, it can go bad if not stored properly.

One of the ways to tell if blue cheese has gone bad is by its smell. Fresh blue cheese has a strong scent, but it changes as it starts to spoil. If your blue cheese has developed an ammonia-like smell, it is likely spoiled and should be discarded. The ammonia smell is caused by the enzymes in the blue cheese continuing to break down, which results in stronger ammonia odours.

In addition to smelling the cheese, you can also examine its colour and texture. The creamy part of fresh blue cheese is typically white, beige, or yellow. If you notice that it has turned pink, brown, or green, it has likely spoiled. Additionally, look for changes in texture, such as a slimy or fuzzy surface, which can indicate spoilage.

It is important to note that blue cheese should be stored properly to prevent spoilage. It should be tightly wrapped and stored in the refrigerator, preferably on the bottom shelf or in a drawer, as these areas are usually the coldest. With proper storage, blue cheese can last 3-4 weeks in the refrigerator.

It's safe to cut away mould and eat the rest

Blue cheese is made using Penicillium, a type of mould that is responsible for its distinct taste, smell, and appearance. While most moulds produce mycotoxins, which are toxic to humans, the Penicillium used in blue cheese production does not produce these toxins and is therefore safe to consume.

That being said, blue cheese can still go bad, so it's important to practice proper food safety and storage. If stored properly in the refrigerator, tightly wrapped, blue cheese can last 3-4 weeks. Freezing blue cheese can also extend its shelf life, although this may alter its texture and appearance slightly.

Now, is it safe to cut away mould and eat the rest? Well, it depends on the type of cheese and the mould in question. For blue cheese, where mould is intentionally introduced during the cheesemaking process, it is generally safe to cut away any mould that develops and consume the remaining cheese. This is because the mould in blue cheese is non-toxic to humans. However, it is important to note that this only applies to the mould intentionally added to blue cheese and not to other types of mould that may develop due to spoilage.

For other types of cheese, it is generally recommended to discard the entire product if mould is present. This is because other moulds may produce toxins that are harmful to humans. However, the USDA provides guidelines for hard cheeses (excluding those where mould is part of the processing), stating that it is safe to cut away at least 1 inch (2.5 cm) around and below the mouldy spot. Nonetheless, it is always important to exercise caution when it comes to food safety, and if in doubt, it is best to discard the cheese entirely.

Store it in a very cold place to slow its ripening

Blue cheese is a pungent and divisive dairy product with a relatively short shelf life. Its distinctive mould, colour and smell are all key indicators of its freshness. But how long will blue cheese last in the fridge?

Storing blue cheese in a very cold place is an effective way to slow its ripening. Blue cheese is best kept in the refrigerator, ideally in the drawers at the bottom, where the temperature is most stable. The colder the blue cheese, the longer it will stay fresh.

To keep blue cheese fresh for as long as possible, it is important to ensure the cheese can breathe. It is recommended to use a variety of wrappers, such as aluminium foil, parchment paper, or even a loose zipper-lock bag. One effective method is to first wrap the cheese in parchment paper and then cover it with a loose layer of aluminium foil. This technique mimics the two-ply construction of cheese paper.

Blue cheese can last for 3-4 weeks in the refrigerator if stored properly. For optimal freshness, the refrigerator temperature should not be set above 40 degrees Fahrenheit.
