Blue Cheese: How Long Does It Last Once Opened?

Blue cheese is a pungent, mouldy cheese with a strong smell and flavour. But how long does it last once opened? When kept in the refrigerator, blue cheese can last for up to three to four weeks. If you want to keep it longer, you can freeze it, which will make it safe to eat indefinitely, although the texture and taste may be slightly altered. To keep blue cheese fresh for as long as possible, it should be wrapped tightly and stored in the refrigerator, ideally in the bottom section, which is usually the coldest.

Blue cheese can be stored in the freezer for up to 6-8 months

Blue cheese is a pungent and distinctive variety of cheese, but it can be stored for a long time if you follow some simple steps. If you're planning to keep blue cheese for an extended period, the freezer is your best option.

Firstly, it's important to note that blue cheese should be refrigerated at all times, and the colder it is, the longer it will stay fresh. So, if you're keeping it in the fridge, make sure it's on the bottom shelf, or in a drawer, where it's coldest. If you're storing blue cheese in the fridge, it will last for around 1-2 months.

However, blue cheese can be stored in the freezer for up to 6-8 months. To do this, cut the cheese into portions no larger than half a pound each. Then, wrap the cheese tightly in heavy-duty aluminium foil or plastic freezer wrap, or place it inside a heavy-duty freezer bag. This will ensure the cheese stays fresh for as long as possible.

Freezing blue cheese can slightly alter its texture and appearance, and it may become crumbly. It's also best suited to cooked dishes, such as sauces, soups, and casseroles, as it loses some of its sharp flavour. But, if you're looking to keep your blue cheese for as long as possible, the freezer is the best option.

It can be stored in the refrigerator for 3-4 weeks

Blue cheese is a pungent variety of cheese with a strong scent and sharp taste. It is made using cultures of Penicillium, a type of edible mould. While blue cheese is perfectly safe to eat, it can go bad if not stored properly.

To keep blue cheese fresh for as long as possible, it should be wrapped and stored in the refrigerator. The ideal refrigerator temperature is below 40 degrees Fahrenheit. It is also recommended to store blue cheese on the bottom shelf of the refrigerator, as this is usually the coldest part.

When properly stored, blue cheese can last for 3-4 weeks in the refrigerator. It is best to check the expiration date on the packaging, as blue cheese will typically remain good for one to two weeks past this date.

To extend the shelf life of blue cheese even further, it can be stored in the freezer. Frozen blue cheese can last indefinitely, although its texture and appearance may be slightly altered. For optimal taste and texture, it is recommended to consume frozen blue cheese within six months.

It is important to note that blue cheese can spoil even when stored in the refrigerator. Signs of spoilage include changes in colour, texture, smell, or taste. If the creamy part of the cheese turns pink, brown, or green, or if it develops a slimy or fuzzy surface, it should be discarded. Additionally, if the cheese emits a strong ammonia-like smell or becomes too biting in taste, it is likely spoiled.

Unrefrigerated blue cheese should be discarded after two days

Blue cheese is a semi-soft cheese with a strong smell and distinct flavour. It is made using cultures of Penicillium, a type of mould.

Blue cheese should always be refrigerated to keep it fresh. If left unrefrigerated, it will spoil quickly and should be discarded after two days.

The ideal temperature for storing blue cheese is between 46°F–55°F (or 8°C–13°C). This is the temperature range in which the cheese matures, so storing it at this temperature will help to preserve it for longer. The lower section of the fridge is usually the coldest, so the bottom shelf or drawers are the best places to store blue cheese.

To further extend the shelf life of blue cheese, it can be frozen. When freezing blue cheese, cut it into pieces no larger than half a pound each, then double wrap the cheese in wax or parchment paper, followed by plastic wrap or foil. Place the wrapped cheese in a plastic freezer bag to protect it from freezer burn. Frozen blue cheese will maintain its best quality for about eight months, but it can be stored safely beyond this time.

Whether refrigerated or frozen, blue cheese should always be tightly wrapped to ensure it stays fresh for as long as possible.

Blue cheese is made using Penicillium, a type of edible mould

Firstly, raw milk (cow, sheep, or goat) is pasteurized and then acidified by adding a starter culture to convert lactose to lactic acid, changing the milk from liquid to solid. Rennet is then added to further coagulate the milk, and the curds are cut to release the whey. The curds are then drained and formed into wheels. At this stage, Penicillium roqueforti is sprinkled over the cheese, and it is salted to prevent spoilage. The cheese is then left to age for 60 to 90 days.

The cheese's signature blue veins are created during the early aging stage when the cheese is "spiked" with stainless steel rods to let oxygen circulate and encourage the growth of the mould. This process softens the texture and develops the cheese's distinctive blue flavour. The piercing of the cheese allows the Penicillium roqueforti to grow along the surface of the curd-air interface, creating the characteristic blue veins.

The mould Penicillium roqueforti is responsible for the distinct taste, smell, and appearance of blue cheese. It is important to note that while other types of mould produce toxins that are harmful to humans, the varieties of Penicillium used in cheesemaking do not produce toxins and are safe to consume.

Blue cheese can be stored in the refrigerator for up to three weeks if wrapped in foil or parchment or waxed paper. It can also be frozen in an airtight container or a zip-close bag for up to three months. However, freezing may alter the texture and flavour of the cheese, making it more crumbly and diminishing its flavour.

It should be stored on the bottom shelf of the refrigerator

To ensure your blue cheese lasts as long as possible, it's important to store it on the bottom shelf of the refrigerator. The lower section of the fridge is typically the coldest part, and by storing it here, you can preserve your blue cheese for longer. If your refrigerator has bottom drawers, this is the ideal place to store blue cheese, as the temperature will remain stable.

The bottom shelf of the refrigerator is the optimal location for storing blue cheese because it is usually the coldest area. This helps to maintain the freshness of the cheese by slowing down bacterial growth. Blue cheese is susceptible to spoilage due to its high moisture content, so keeping it in a cold environment is crucial for extending its shelf life.

Additionally, storing blue cheese on the bottom shelf can help prevent it from picking up scents or flavours from other items in the refrigerator. This is especially important for blue cheese, as it has a strong scent and flavour that can be easily affected by its surroundings.

To further extend the shelf life of blue cheese, proper wrapping and storage are essential. Before placing it on the bottom shelf, ensure that your blue cheese is properly wrapped. First, wrap it in wax or parchment paper. Then, cover it with plastic wrap or foil to prevent it from drying out. If you're concerned about odour absorption or flavour transfer, you can place the wrapped cheese in an airtight container for added protection.

By storing blue cheese on the bottom shelf of the refrigerator and following proper wrapping techniques, you can maximise its freshness and enjoy it for a longer period.
