Blue Cheese: How Long Can It Stay Out?

Blue cheese is a pungent, medium-hard cheese injected with mould to create a strong taste and smell. It is safe to eat at room temperature, but for no longer than four hours. This is because, after this time, bacterial growth or spoilage may occur. Blue cheese should be refrigerated and, if possible, consumed within one to two weeks of purchase.

Blue cheese should be refrigerated to keep it fresh

Blue cheese is a delicate product that requires careful storage to maintain its freshness. While the cheese itself has a bold flavour and a pungent smell, these characteristics should not be confused with the signs of spoilage. To keep blue cheese fresh for as long as possible, it is important to refrigerate it.

Blue cheese is a medium-hard, creamy cheese that is injected with mould to create its distinctive flavour and aroma. The mould colouring, along with the smell, can sometimes mask spoilage. Therefore, it is important to know how to identify when blue cheese has gone bad. The first sign is a change in colour—if the creamy parts of the cheese turn pink, brown, or green, it is likely spoiled. Additionally, if the surface appears slimy or fuzzy, or has an ammonia-like smell, it should be discarded.

To maintain the freshness of blue cheese, it is recommended to wrap it properly. Wrapping it in wax or parchment paper, followed by a layer of plastic wrap or foil, helps prevent moisture buildup and keeps the cheese from drying out. It is also advisable to rewrap the cheese each time it is used. When storing blue cheese in the refrigerator, it is best to place it on the bottom shelf, as it is usually the coldest part. The ideal temperature for refrigeration is below 40 degrees Fahrenheit.

While blue cheese can be stored at room temperature, it should not be left out for an extended period. To achieve the optimal texture and flavour, it is recommended to let the cheese sit at room temperature for 30 to 60 minutes before serving. However, it should not be left out for more than four hours to avoid spoilage. If left unrefrigerated for too long, blue cheese will spoil more quickly and may develop unwanted bacteria.

In summary, blue cheese should be refrigerated to maintain its freshness. Proper wrapping, storage in the coldest part of the refrigerator, and limited exposure to room temperature will help extend the shelf life of blue cheese and preserve its quality.

It's best to re-wrap blue cheese every time you use it

Blue cheese is best stored in a climate with high humidity—at least 80% humidity is recommended to keep the cheese paste fresh. The tricky part is ensuring that the cheese stays in a humid climate without trapping moisture. If you're storing blue cheese in the refrigerator, it can last quite a while. In most cases, it will remain good for one to two weeks past the expiration date, meaning it will last in the fridge for three to four weeks.

If you're storing blue cheese at room temperature, it's best to keep it out for no longer than four hours to avoid bacterial growth or spoilage. If you're storing blue cheese on the counter in a traditional cheese dome, be sure to lift the dome to allow fresh air to get to the cheese so it doesn't suffocate.

To store blue cheese, it's recommended to wrap it in wax or parchment paper, then place plastic wrap or foil over the paper to ensure that it won't dry out. If you're concerned about the cheese picking up the scent or flavours of other items in the refrigerator, you may want to place it in an airtight container after it's been wrapped for additional protection.

Don't leave blue cheese unrefrigerated for more than four hours

Blue cheese is a delicate product that requires careful storage. It is a medium-hard, creamy cheese injected with mould to create a pungent taste and smell. The cheese paste is often fragile, with pierced blue veining, making it more susceptible to oxidation and moisture loss.

When storing blue cheese, it is essential to strike a balance between humidity, airflow, and breathability. The ideal climate for blue cheese is one with high humidity, at least 80%, to keep the cheese paste fresh. However, it is crucial to ensure that moisture is not trapped on the surface of the cheese, as this can lead to rapid degradation and the growth of inedible, pinkish bacteria.

To prevent moisture buildup, it is recommended to wrap blue cheese in cheese paper or bee's wrap, avoiding plastic wrap or tight wrapping, which can trap moisture and promote bacterial growth. Additionally, allowing the cheese to breathe is vital; if stored in plastic or paper, it should not be left in contact with the cheese for an extended period.

When serving blue cheese, it is best to remove it from the refrigerator 30 to 60 minutes beforehand to bring it to room temperature, enhancing its texture and flavour. However, it is important not to leave blue cheese unrefrigerated for more than four hours. According to food safety experts, this timeframe applies to all cheeses to prevent bacterial growth and spoilage.

Leaving blue cheese unrefrigerated for more than four hours can lead to deterioration in quality and an increased risk of spoilage. While harder cheeses like Parmesan can be left out for longer without significant bacterial growth, blue cheese, with its higher moisture content, is more vulnerable to spoilage.

In summary, to ensure the best quality and safety of blue cheese, it should be stored wrapped in cheese paper or bee's wrap in a humid section of the refrigerator. When serving, allow it to reach room temperature, but do not leave it unrefrigerated for more than four hours to prevent spoilage and maintain food safety.

Blue cheese should be wrapped in paper, not plastic

Blue cheese is a pungent and delicate treat, and keeping it fresh requires a little extra care. When storing blue cheese, it is important to remember that it should be wrapped in paper, not plastic.

Firstly, blue cheese is a living, breathing organism, and it needs to be stored as such. Wrapping it in plastic suffocates the cheese, killing off the good microorganisms and altering its flavour. Cheese paper, butcher paper, or parchment paper are the best options, as they allow the cheese to breathe while still protecting it. If you don't have any paper to hand, you can use a layer of plastic wrap over the top of the paper to ensure it doesn't dry out.

Secondly, blue cheese is more susceptible to oxygen than other cheeses. Oxygen encourages the growth of mycelia and spores, which create the blue veins in the cheese. Wrapping the cheese in plastic or airtight foil encourages this process, turning the cheese blue and altering its flavour.

Thirdly, blue cheese is prone to drying out. Plastic wrap does not allow the cheese to breathe, and the cold, dry air of the refrigerator will sap the moisture from the cheese, leaving it dry and crumbly. Paper, on the other hand, wicks excess moisture away from the cheese while still allowing it to breathe.

Finally, blue cheese is delicate and can be contaminated by other foods. Plastic wrap can cause the cheese to take on the flavours of other items in the refrigerator, and it is also more likely to come into contact with bacteria. Paper, on the other hand, provides a protective barrier while still allowing the cheese to breathe.

In conclusion, blue cheese should always be wrapped in paper, not plastic. This allows the cheese to breathe, prevents it from drying out, and protects it from contamination and unwanted flavour alterations.

Blue cheese can be frozen to be preserved indefinitely

Blue cheese is a tricky cheese to store. Its delicate cheese paste with pierced blue veining makes it susceptible to oxidation and loss of surface moisture. It is best to store blue cheese in a climate with high humidity (at least 80%) to keep the cheese paste fresh.

Blue cheese should be stored in the refrigerator to maximise its shelf life. Properly stored, a wedge of blue cheese will last for about 1 to 2 months in the refrigerator. To further extend its shelf life, it can be frozen. To freeze a wedge of blue cheese, cut the cheese into portions no larger than half a pound each and wrap it tightly in heavy-duty aluminium foil or plastic freezer wrap, or place it inside a heavy-duty freezer bag. Frozen in this way, blue cheese will maintain its best quality for about 6 months but will remain safe to eat beyond that time.

If you want to store blue cheese at room temperature, it is best to use a Cheese Grotto, which self-regulates high humidity and has a breathable back panel to allow fresh air supply to circulate around the cheese gently. This prevents moisture from being trapped on the surface of the cheese, which can result in the rapid degradation of the cheese and the emergence of unwanted, pinkish bacteria that is inedible.
