Cheese Expiry: How Long Does It Actually Last?

Whether or not cheese can be consumed after its best-before date depends on several factors, including the type of cheese, how it has been stored, and the degree of spoilage. Hard cheeses like Cheddar, Parmesan, and Gouda are more likely to be safe to eat past their expiration dates if they are properly stored and show no signs of spoilage. Soft and fresh cheeses, on the other hand, have a shorter shelf life and are more perishable. It is important to inspect the cheese for signs of spoilage such as mold, odd odors, a slimy texture, or a sour flavor before consuming it. While some molds on cheese are harmless, others can produce dangerous toxins. In general, soft cheeses should last about a week in the fridge after opening, while hard cheeses can last three to four weeks.

Hard cheese can last for several months to a year if unopened and stored properly

Hard cheese, such as Cheddar, Parmesan, and Gouda, can last for several months to a year if left unopened and stored properly. This is because they have a lower moisture content, which helps to extend their shelf life.

When stored in the refrigerator, hard cheeses can be kept for even longer, with some sources suggesting they can last for up to a year or more. However, it is important to note that the shelf life of hard cheese is influenced by factors such as the type of cheese, the processing method, packaging date, exposure to heat, and the "best before" date.

To extend the shelf life of hard cheese, it should be stored in the refrigerator at 40°F or lower, either in its original wrapper or a tightly closed container to keep out moisture and other contaminants. Bacteria cannot grow as readily in dry environments, which is why hard cheese keeps longer than soft.

Additionally, hard cheese should be stored below raw meats, poultry, and fish to avoid contamination. It should also be wrapped in porous material like wax, parchment, or cheese paper to prevent it from drying out.

When it comes to determining if hard cheese is safe to eat, it is important to inspect it for any signs of spoilage. This includes mold, odd odors, a slimy texture, or a sour flavor. If there is mold on hard cheese, it is generally safe to cut off at least 1 inch (2.5 cm) around and below the moldy spots. However, if there is mold on soft cheese, it is best to discard the entire product.

In summary, hard cheese can last for several months to a year if left unopened and stored properly, but it is important to regularly inspect it for any signs of spoilage to ensure it is still safe to consume.

Soft cheese has a shorter shelf life, lasting a few weeks to a couple of months unopened

Soft cheese has a shorter shelf life than hard cheese, lasting only a few weeks to a couple of months unopened. This is because soft cheeses have a high moisture content, creating the perfect environment for bacteria to thrive and cause spoilage. Harder, aged cheeses will last much longer as they contain less moisture.

Some examples of soft cheeses include cottage cheese, cream cheese, ricotta, Brie, mozzarella, Neufchâtel, feta, Gorgonzola, and Camembert. These cheeses are usually sold in tubs or containers, rather than blocks, and have a creamy texture.

To extend the shelf life of soft cheese, it's important to store it correctly. Soft cheeses should be kept in the fridge, in a tightly closed container, to prevent moisture loss and to stop bacteria from entering. The ideal temperature for a refrigerator is below 40°F (4°C). At higher temperatures, bacteria can multiply quickly and cause spoilage.

Even when stored correctly, soft cheese will only last a few weeks. After opening, soft cheeses will usually last for 1-2 weeks in the fridge. It's important to inspect soft cheese for any signs of spoilage before consuming it, even if it is within the recommended storage time.

Signs of spoilage in soft cheese include mould, a darker colour, a harder texture, and a stronger smell. If any of these signs are present, the entire cheese should be discarded. It is not recommended to cut off mouldy parts of soft cheese, as harmful bacteria may have spread throughout the cheese.

Therefore, soft cheese has a shorter shelf life than hard cheese, and it's important to consume it within a few weeks of purchasing to ensure food safety and optimal flavour.

Fresh cheese is highly perishable and usually lasts a few weeks past its 'best before' date

Fresh cheese is highly perishable and will usually only last a few weeks past its best-before date. This is because fresh cheeses like cream cheese, ricotta, and cottage cheese have a high moisture content, making them more prone to bacterial spoilage.

When stored in the refrigerator, opened fresh cheeses like ricotta and cottage cheese have a short shelf life and are best consumed within a week or two of opening. It is important to note that the best-before date is a guideline for quality rather than safety, and cheese often remains safe to eat beyond this date if stored correctly. However, it is always recommended to check for signs of spoilage such as mold, odd odors, a slimy texture, or a sour flavor before consuming any cheese past its best-before date.

To extend the shelf life of fresh cheese, it is important to store it properly. Fresh cheese should be stored in the refrigerator at 40°F or lower immediately after each use. It should also be stored in its original wrapper or a tightly closed container to keep out moisture and other contaminants. Bacteria cannot grow as readily in dry environments, which is why hard cheeses tend to keep longer than soft ones.

It is worth noting that the harder the cheese, the longer it keeps. This is because hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content, which helps extend their shelf life. Unopened hard cheeses can last for several months and even up to a year when stored in the refrigerator. On the other hand, soft cheeses like Brie and Camembert have a shorter shelf life, typically lasting only a few weeks to a couple of months past their best-before date when refrigerated.

Blue cheese can last for several months unopened if it's refrigerated properly

Blue cheese is a pungent, semi-hard cheese with a unique mould that is perfectly safe to eat. It is a popular dairy product that is nutritious, versatile and tasty.

When unopened, blue cheese can last for several months if it is refrigerated properly. The exact length of time depends on the storage conditions and the type of packaging. For example, if the cheese is wrapped in cheese paper and inside a carton package, it will have a shorter shelf life than if it is sealed airtight. In general, unopened blue cheese will come with a shelf life of one to six months and will retain its quality for a couple of extra weeks.

To extend the shelf life of blue cheese, it is best to store it in the refrigerator at a temperature of around 40°F (4°C) or lower. The lower the temperature, the longer the cheese will stay fresh. It is also important to wrap the cheese properly to ensure that it doesn't dry out. First, wrap the cheese in wax or parchment paper, then cover it with plastic wrap or foil. If you are freezing the cheese, place it in a freezer bag to protect it from freezer burn.

Signs that your blue cheese has gone bad include the presence of fuzzy mould (the blue mould native to blue cheese is not fuzzy), an altered colour (the flesh is normally white, beige or yellow, so if it turns pink, green, brown or yellow, it should be discarded), a strong ammonia-like smell, or a dry, crumbly, and uneven appearance.

In summary, blue cheese can last for several months if it is unopened and refrigerated properly. To maximise its shelf life, it should be stored in the right conditions and properly wrapped.

Cheddar can last for several months to over a year unopened if stored in the fridge

Cheddar is a semi-hard cheese, which means it has been cooked and pressed but not aged. This means it contains more moisture than hard cheeses. As a result, unopened Cheddar will last several months to over a year if stored in the fridge. However, once opened, exposure to air and potential bacterial contamination mean that Cheddar will only last a few weeks to a couple of months.

The shelf life of Cheddar depends on a variety of factors, such as the type of cheese, the processing method, its packaging date, exposure to heat, how the cheese is stored, and its best-before date or sell-by date.

It's important to note that the best-before date on cheese is a guideline for quality rather than safety. Cheese often remains safe to eat beyond these dates if it's stored correctly. The same is true of sell-by dates, which are simply the last date by which a manufacturer will vouch for a product's quality, not its safety.

To extend the shelf life of Cheddar, it should be stored in the fridge at 40°F or lower immediately after each use, either in its original wrapper or a tightly closed container to keep out moisture and other contaminants. Bacteria can't grow as readily in dry environments, which is why hard cheese keeps longer than soft.

You can also freeze Cheddar for a few months while preserving its taste if you use a freezer-safe container that is void of oxygen. While letting the formerly frozen cheese thaw in the refrigerator is the preferred method, some may be used in their frozen state for baking.

To determine whether your Cheddar has gone bad, use your senses. Some common traits of cheese going bad are a darker colour and harder texture, accompanied by a stronger smell. Your cheese has gone bad when you see or smell mould growth. If there is mould on softer cheeses, throw them away. Likewise, if there is mould on some of your shredded cheese, the entire container should be thrown out. For firmer cheeses, if you cut away the mould and an inch of the cheese surrounding the mould (without touching the mould with your knife), it is still fine to cook with. Although some moulds on cheese are harmless (as with blue cheese), some produce very dangerous toxins.
