Cheese Lifespan: How Long Does It Last In The Fridge?

Cheese is a beloved staple in many kitchens, but it can be hard to know how long it will last in the fridge. The shelf life of cheese depends on several factors, including the type of cheese, moisture content, storage practices, and preservatives. Generally, soft cheeses like ricotta, feta, and mozzarella have a shorter shelf life of about one to two weeks, while harder cheeses like aged cheddar, gouda, and parmesan can last up to four weeks or even longer. Proper storage methods, such as wrapping cheese in breathable materials like wax or parchment paper, can also extend the shelf life. Freezing is not recommended for most cheeses, as it can affect their texture. To ensure food safety, it's important to inspect cheese for signs of spoilage, such as mold, dryness, or unusual odours, and to store it at a safe temperature below 40°F (4°C).

Soft cheeses last 1-2 weeks in the fridge

Soft cheeses, such as ricotta, feta, and mozzarella, are highly perishable due to their high moisture content, which provides an ideal environment for bacterial growth. Therefore, soft cheeses will typically last for about one to two weeks in the fridge. However, it is important to note that the quality and taste of soft cheeses will start to decline before the end of this timeframe.

To maximise the shelf life of soft cheeses, proper storage is essential. For soft cheeses sold in brine, such as feta or fresh mozzarella, ensure they are fully submerged in the liquid and store them in a container with a secure lid. For blue cheese, it is recommended to wrap it in foil. Soft-ripened cheeses like Brie have a delicate rind and require more careful storage. It is best to wrap them in cheese paper or parchment paper and store them in an airtight container.

Additionally, it is advisable to only buy cheese for the week ahead, as a wedge of cheese starts to decline as soon as it is cut. Proper storage methods can help extend the shelf life of soft cheeses and maintain their quality.

It is also important to inspect soft cheeses for any signs of spoilage before consumption. If there is visible mold or other signs of deterioration, such as an unpleasant smell or changes in texture, it is best to discard the cheese.

Hard cheeses last 3-4 weeks

Hard cheeses, such as aged cheddar, aged gouda, and parmesan, can last anywhere from 3 to 4 weeks in the refrigerator once opened, according to cheese experts. This is because hard cheeses are low in moisture, making it difficult for bacteria to flourish. Unopened packages of hard cheese can last about six months in the fridge.

To ensure your hard cheese lasts the full 3 to 4 weeks, follow these steps for proper storage:

• Remove the cheese from its plastic packaging.
• Wrap it loosely in a pliable yet breathable material, such as wax paper or cheese paper.
• Put the cheese in a container with an airtight lid.

Additionally, it is important to note that the refrigerator temperature should be maintained below 40°F (4°C) to prevent spoilage. At higher temperatures, bacteria multiply rapidly, increasing the risk of food spoilage.

While hard cheeses have a longer shelf life, they can still spoil. Signs of spoilage in hard cheeses include mold, unintentional bitter flavour, fermented fruit taste, and a fizzy sensation on the tongue. If you notice any of these signs, it is best to discard the cheese.

In summary, hard cheeses can be enjoyed for an extended period when stored correctly in the refrigerator, but it is essential to monitor them for any signs of spoilage to ensure food safety and quality.

Freezing cheese

Freezing is an effective way to preserve cheese and prevent waste. However, it's important to note that freezing affects the texture and quality of cheese, making it drier and crumblier. This is because small ice crystals form inside the cheese, disrupting its internal structure. When the cheese thaws, water is released, causing it to dry out and become crumbly.

Hard and semi-hard cheeses with lower moisture content, such as cheddar, Swiss, blue cheese, and brick cheese, are better suited for freezing than soft cheeses. While freezing doesn't affect the nutrients in the cheese, it can make it harder to slice. Additionally, the cheese may become less meltable when stored for longer periods.

To freeze hard and semi-hard cheeses, portion the cheese into chunks a few inches wide. Wrap each chunk tightly and fully in a layer of parchment paper and then foil. Place the wrapped pieces in a resealable plastic bag, suck out the air, seal the bag, and label it with the contents and date. Freeze the cheese as rapidly as possible to at least -9 °F (-23 °C) to prevent large ice crystals from forming.

For soft cheeses like mozzarella, grate the cheese before freezing. Place the grated cheese in a resealable plastic bag, remove the air, seal, and label. Follow the same freezing instructions as for hard and semi-hard cheeses.

Frozen cheese should be thawed slowly in the refrigerator to allow the moisture to be reabsorbed. It can then be used in cooked dishes like soups, sauces, or casseroles, as freezing can affect the texture, making it less suitable for eating raw.

Signs of spoilage

Cheese is a beloved and versatile food, but it can spoil over time. Here are some signs of spoilage to look out for:

Visible mould

The most obvious sign of spoilage is visible mould. Mould can be white, green, blue, or black. Even a small amount of mould indicates that the entire block of cheese is contaminated and should be discarded. However, for semi-soft to hard cheeses, you can cut off the mouldy parts and safely consume the rest.

Unpleasant odour

Cheese should have a pleasant, slightly tangy aroma. If you notice an unpleasant odour, such as a sour, rancid, sweaty, chlorine-like, or ammonia-like smell, it's likely that the cheese has gone bad. Trust your sense of smell and discard the cheese if it smells off.

Texture changes

Fresh cheddar cheese has a firm and smooth texture. If the cheese feels slimy, sticky, or excessively hard, it's a sign of spoilage. Additionally, grated cheese will not last as long as a solid block and is more prone to spoilage.

Discolouration

Cheddar cheese typically ranges in colour from pale yellow to deep orange. If you notice any discolouration, such as dark spots, streaks, or patches, it's a sign that the cheese has spoiled. Avoid consuming discoloured cheese as it may harbour harmful bacteria.

Bitter or off-flavours

If you're unsure about the condition of the cheese, you can take a small bite. If the cheese tastes sour, bitter, or has an off-flavour, it's best to discard it.

Expiration date

Always check the expiration date on the cheese packaging. While this date is not always accurate, consuming cheese past its expiration date increases the risk of foodborne illness.

Storage practices

The shelf life of cheese depends on several factors, including storage practices, moisture content, and preservatives. When stored properly, cheese can last anywhere from two weeks to six months in the fridge.

To extend the shelf life of cheese, it is important to follow proper storage practices. Here are some tips to help you store your cheese effectively:

• Storage Container: Cheese should be stored in an airtight container. This helps maintain humidity to prevent dryness while also allowing the cheese to breathe.
• Wrapping: Avoid wrapping cheese in tight, non-porous material like plastic wrap. Instead, opt for porous materials such as wax, parchment, or cheese paper. These materials protect the cheese while allowing it to breathe and release moisture.
• Temperature: Keep your fridge temperature below 40°F (4°C). Higher temperatures increase the rate of bacterial growth, leading to faster spoilage.
• Shelf Placement: Store cheese on the top or middle shelf of the fridge, or in a drawer. Avoid placing it on the door shelves, as these areas are more susceptible to temperature fluctuations.
• Separation from Other Foods: Keep cheese away from raw meats, poultry, and fish to avoid cross-contamination.
• Handling: Avoid touching the cheese with your hands, even if they are freshly washed. Use utensils or a spoon when handling shredded cheese.
• Brine: For cheese sold in brine, such as feta or fresh mozzarella, keep it submerged in the liquid and ensure the container is securely closed.
• Foil Wrapping: Blue cheese is best stored in aluminium foil. Its higher moisture content and unique mold require this specific type of wrapping.
• Soft-Ripened Cheese: For delicate cheeses like Brie, wrapping them in cheese paper is ideal. Parchment paper and an airtight container can also be used.
• Semi-Hard and Hard Cheeses: For varieties like cheddar, Gruyère, and aged Gouda, remove them from their plastic packaging. Wrap them loosely in wax paper or cheese paper and place them in an airtight container.
• Freezing: Freezing cheese is not generally recommended, especially for soft cheeses. However, harder cheeses intended for cooking can be frozen for a few months.
