Cheddar Cheese: How Long Does It Last Once Opened?

Cheddar cheese is a semi-hard cheese with a longer shelf life than soft cheeses like mozzarella, feta, and ricotta. Once opened, a block of cheddar cheese will typically last 3 to 4 weeks in the refrigerator. However, its shelf life depends on various factors, such as storage conditions and the type of packaging used.

Storage conditions for opened cheddar cheese

Cheddar cheese is a semi-hard cheese, which means it has less moisture than soft cheese and will therefore last longer in the fridge. To maximise its shelf life, there are a few things to keep in mind.

Firstly, it is important to keep cheddar cheese refrigerated at all times. Cheddar should be stored in the refrigerator at a temperature below 40°F (4°C). Higher temperatures increase the rate at which bacteria multiply, which can cause the cheese to spoil.

Secondly, the way you wrap the cheese is important. Cheddar should be removed from its original plastic packaging and wrapped in a breathable material such as wax paper, parchment paper, or cheese paper. This will protect the cheese while allowing it to release moisture and breathe. You can then place the wrapped cheese in an airtight container or seal it in a plastic bag. Avoid using tight, non-porous materials like plastic wrap to wrap the cheese directly, as this can dry it out.

Finally, it is important to regularly inspect your cheese for any signs of spoilage. An opened package of cheddar cheese will typically last about 3 to 4 weeks in the refrigerator. However, if you notice any mold, hard texture, discolouration, or a strong smell, the cheese should be discarded. If you notice surface mold on hard cheese, you can cut off at least 1 inch (2.5 cm) around and below the affected area and re-cover the cheese with fresh wrap.

To further extend the shelf life of cheddar cheese, you can freeze it. Cut the cheese into portions no larger than 1/2 pound each, and wrap them tightly in heavy-duty aluminum foil or plastic freezer wrap, or place them in a heavy-duty freezer bag. Frozen cheddar cheese will maintain its best quality for about 8 months but will remain safe to consume beyond that time if stored at a constant temperature of 0°F (-18°C).

How to wrap opened cheddar cheese

Cheddar cheese is a hard cheese, and hard cheeses last three to four times longer in the fridge than soft cheeses. This is because they contain less moisture and are therefore less prone to spoilage from bacteria. An opened block of cheddar cheese will last about three to four weeks in the refrigerator.

• Avoid storing your cheese in an airtight container, as this can contribute to moisture and flavour loss.
• Wrap your cheese in specialist cheese or wax paper, and place it into the bottom drawer of your fridge.
• If you don't have specialist cheese paper, you can use wax paper, parchment paper, or beeswax wraps.
• Avoid using plastic wrap if possible, as this can dry the cheese out and harden it. However, if you do use plastic wrap, first wrap the cheese in wax or parchment paper and then cover it with plastic wrap.
• Label the cheese with the variety and date.
• Place the wrapped cheese in a designated container, drawer, or airtight plastic bag.
• Keep your cheese in the warmest part of the refrigerator, such as the cheese or vegetable drawer.

How to identify if opened cheddar cheese has gone bad

Cheddar cheese is a semi-hard cheese with a relatively long shelf life. However, it's important to know how to identify if opened cheddar cheese has gone bad to ensure food safety and optimal taste. Here are some detailed signs and indicators to look out for:

Check the Best-By Date

While not a definitive indicator, the "best-by" date on the package provides a general timeframe for consumption. Opened cheddar cheese will typically remain safe to consume for 3 to 4 weeks, even after the "best-by" date.

Inspect for Mold

Visually inspect the cheese for any signs of mold. If you spot any blue, gray, or green mold on your cheddar cheese, it's best to discard it. These types of mold can indicate spoilage and potential health risks. Cut off at least 1 inch (2.5 cm) around and below the moldy spots if you decide to risk it, but this is not recommended.

Texture and Colour Changes

Observe any changes in the texture and colour of the cheese. Cheddar cheese that has gone bad may develop a very hard texture and darken in colour. These changes indicate that the cheese is no longer fresh and should be discarded.

Unpleasant Odour

Use your sense of smell to detect any unpleasant odours coming from the cheese. Cheddar cheese that has spoiled may emit a strong, pungent odour. A sweaty, chlorine-like, or ammonia-like smell indicates that the cheese is no longer safe to consume.

Bitter or Unusual Taste

If you notice any bitter or unusual flavours when tasting the cheese, it's best to discard it. A bitter taste or fermented fruit taste is a clear sign of spoilage and should not be ignored.

Yeasty or Fermented Smell

Pay attention to any yeasty or fermented smells coming from the cheese. This can be an indicator of bacterial growth and spoilage, especially in cheeses with higher moisture content. An unpleasant fermented smell is a sign that the cheese has turned.

Fizzy Sensation on the Tongue

If you experience a fizzy or tingling sensation on your tongue after consuming the cheese, discard it immediately. This sensation is an indicator of spoilage and can be harmful.

Storage Conditions

Consider the storage conditions of the cheese. Cheddar cheese should be refrigerated at all times and wrapped properly to maximize its shelf life. If the cheese has been left at room temperature for an extended period or has not been adequately wrapped, it may spoil faster.

In summary, identifying if opened cheddar cheese has gone bad involves a combination of visual inspection, sensory evaluation (smell and taste), and consideration of storage conditions. By following these indicators, you can ensure that you consume the cheese safely and at its optimal quality.

How to freeze opened cheddar cheese

Cheddar cheese is a hard cheese that freezes well. Freezing is a great way to preserve cheese and prevent it from spoiling. Here is a step-by-step guide on how to freeze opened cheddar cheese:

Step 1: Cut the Cheddar Cheese into Portions

Start by cutting the cheddar cheese into portions or blocks. The portions should not be larger than half a pound each. Cutting the cheese into smaller portions will make it easier to thaw and use later on.

Step 2: Wrap the Cheddar Cheese

Once the cheese is cut into portions, wrap each piece tightly in heavy-duty plastic freezer wrap or aluminium foil. Alternatively, you can place the cheese inside a heavy-duty freezer bag. If using a freezer bag, ensure that you remove as much air as possible before sealing. You can also use a combination of wraps, such as first wrapping the cheese in wax or parchment paper and then covering it with plastic wrap. This will help maintain its moisture and prevent freezer burn and odours from affecting the flavour.

Step 3: Label and Date the Cheddar Cheese

Always label the wrapped cheese with the type of cheese and the date before placing it in the freezer. This will help you keep track of how long it has been frozen and ensure you consume it within its recommended frozen shelf life.

Step 4: Store the Cheddar Cheese in the Freezer

Place the wrapped or bagged cheese in the freezer. Cheddar cheese can be stored in the freezer for up to eight months and will remain safe beyond that time if kept at a constant temperature of 0°F (-18°C) or below.

Step 5: Thaw the Frozen Cheddar Cheese

When you are ready to use the frozen cheddar cheese, thaw it slowly in the refrigerator. Avoid thawing it at room temperature to prevent texture changes. Place the cheese in its original packaging or a sealed bag/container and allow it to thaw for a couple of hours or overnight. You can also use the cheese frozen by grating, melting, or crumbling it directly into dishes.

Step 6: Use the Thawed Cheddar Cheese

Once the cheddar cheese is thawed, it is best suited for cooking applications rather than serving fresh. The texture of the cheese may change slightly, becoming more crumbly and mealy. Use the cheese in cooked dishes such as casseroles, sauces, soups, grilled cheese sandwiches, or macaroni and cheese.

How long does opened and shredded cheddar cheese last

Cheddar cheese is a hard cheese, and hard cheeses last three to four times longer in the fridge than soft cheeses. This is because they contain less moisture and are therefore less prone to spoilage from bacteria.

Once opened, hard cheese is typically safe to eat for about three to four weeks. However, if you grate and shred the cheese, it will only last for about five to seven days in the refrigerator. To maximise its shelf life, seal the original packaging tightly or place the cheese in resealable plastic bags or airtight containers.

If you want to keep shredded cheddar cheese for longer, you can freeze it. Frozen cheddar cheese will maintain its best quality for about eight months, but it may lose some of its texture and flavour. It will be best suited to cooked dishes, such as sauces, soups, and casseroles.

To identify if your cheese has gone bad, use your senses. If the cheese has developed a hard texture, darkened in colour, or has a strong smell, it has likely gone bad. If you see mould, discard the cheese.
