Cheese Storage: How Long Does Packaged Cheese Last?

Cheese is a tasty, nutritious, and versatile food, but it's important to know how long it lasts in the fridge once opened to avoid eating spoiled cheese. The shelf life of packaged cheese depends on the type of cheese and how it's stored. Soft cheeses like mozzarella, feta, and goat cheese are more perishable and typically last for about a week in the fridge after opening. On the other hand, hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content, making it harder for bacteria to grow, and can last for three to four weeks in the fridge once opened. Proper storage is key to extending the shelf life of cheese. It's recommended to remove the cheese from its plastic packaging and wrap it loosely in breathable material like wax paper before placing it in an airtight container.

Soft cheeses like mozzarella, feta, and ricotta should last about a week in the fridge

Soft cheeses tend to spoil more quickly than hard cheeses. This is because they have a higher moisture content, which creates a breeding ground for bacteria. Soft cheeses like mozzarella, feta, and ricotta should last about a week in the fridge.

Feta packed in liquid salt brine can last for up to 6 months if stored correctly. To store it correctly, keep the cheese in its original container, ensuring that the block is completely submerged in brine and that care has been taken to avoid contamination. However, once the package is open, it's best to use feta within a week.

To extend the life of feta, use a clean implement like tongs or a fork when removing a portion of the cheese from the brine. If you don't have enough brine to submerge your feta, you can make your own by mixing 1/2 cup whole milk, 1/2 cup water, 1-1/2 teaspoons table salt, and 1/2 teaspoon distilled white vinegar. Place the feta in the brine in an airtight container and refrigerate for one week.

Mozzarella, on the other hand, has a longer shelf life when unopened. Unopened balls of fresh mozzarella are safe to eat even after their expiration date.

Like mozzarella, unopened ricotta cheese is good for about two weeks in the fridge. Once opened, it will last for about a week in the fridge. To be on the safe side, give it the sniff test. If there is any off odor, toss it. Additionally, if there are any black spots, it’s got to go. Other signs of spoilage include discoloration, excess liquid, and texture issues (graininess, lumpiness).

Hard cheeses like aged cheddar, gouda, and parmesan can last 3-4 weeks

Hard cheeses, such as aged cheddar, gouda, and parmesan, are low in moisture, making it difficult for bacteria to flourish. This means that once opened, a package of hard cheese can last a long time—up to 3-4 weeks in the refrigerator. This is in contrast to soft cheeses, which tend to spoil more quickly and should last around 7 days in the fridge after opening.

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

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

It's important to note that hard cheeses can also be stored without refrigeration, although they will last much longer if they are refrigerated. Unopened blocks of hard cheese can last up to 6 months in the fridge.

When it comes to determining whether your hard cheese is still safe to eat, there are a few signs to look out for. Firstly, inspect the cheese for any mould before eating and cut off any spots. White specks or crystallized patches on certain aged hard cheeses like cheddar, parmesan, and gouda are normal and safe to eat. These spots are most likely not mould but calcium lactate crystals, which form when the lactic acid in cheese combines with calcium.

Other signs that your hard cheese has gone bad include an unintentional bitter flavour, a fermented fruit taste, and a fizzy sensation on the tongue. The cheese may also exhibit changes in texture, becoming overly dry, crumbly, or slimy. Significant changes in colour, such as yellowing or browning, can also indicate spoilage. If you're unsure, it's best to err on the side of caution and not consume the cheese.

Fresh cheeses like cream cheese, cottage cheese, and ricotta are perishable and should be consumed within a week or two

Fresh cheeses like cream cheese, cottage cheese, and ricotta are highly perishable and should be consumed within a week or two of opening. These cheeses have a high moisture content, which makes them more prone to bacterial growth and spoilage than harder cheeses.

To extend the shelf life of these fresh cheeses, proper storage is essential. Fresh cheeses should be stored in the refrigerator, in their original packaging, and kept at a temperature below 40°F (4°C). If the cheese did not come in resealable packaging, it can be wrapped in wax, parchment, or cheese paper. It should then be placed in an airtight container and stored on the top or middle shelf of the fridge, or in a drawer. It is important to keep fresh cheeses away from raw meats, poultry, and fish to avoid contamination.

Even with proper storage, fresh cheeses like cream cheese, cottage cheese, and ricotta are best consumed within a week or two of opening. After this time, they may develop signs of spoilage, such as mould, a sour smell, changes in texture, discolouration, or an off-flavour. If any of these signs are present, the cheese should be discarded.

In summary, fresh cheeses like cream cheese, cottage cheese, and ricotta are perishable and have a short shelf life, even when stored properly. To ensure food safety and the best quality, it is recommended to consume these cheeses within a week or two of opening.

Semi-hard cheeses like Swiss cheese and Monterey Jack have a shelf life of 2-3 weeks

Once you've opened a package of cheese, the clock starts ticking on how long it will stay fresh. For semi-hard cheeses like Swiss cheese and Monterey Jack, you can expect a shelf life of approximately 2 to 3 weeks. This type of cheese is known for its moderate moisture content, which contributes to its relatively short shelf life compared to harder cheeses. However, with proper storage, you can maximize the freshness and enjoy your cheese at its best.

When it comes to storing semi-hard cheeses, the key is to maintain a consistent temperature and provide an airtight environment. Ideally, you should wrap the cheese tightly in plastic wrap or aluminum foil, ensuring that no part of the cheese is exposed to air. This creates a barrier that prevents moisture loss and slows down the growth of mold. Additionally, you can place the wrapped cheese in an airtight container or a resealable bag to add an extra layer of protection.

The optimal storage temperature for semi-hard cheeses is between 35°F and 40°F (1.6°C and 4.4°C). Most home refrigerators typically maintain temperatures slightly colder than this range. Aim to store your cheese in the warmest part of the fridge, which is usually the top shelf or a dedicated drawer. This helps prevent the cheese from drying out or developing an overly strong flavor.

During storage, it's important to regularly inspect your semi-hard cheese for any signs of spoilage. Mold can develop even under proper storage conditions. If you spot mold, cut away the affected part, ensuring you remove at least 1 inch (2.5 cm) around the moldy area. Transfer the cheese to a new wrap or container, as mold spores may still be present in the previous wrapping. Also, remember that the shelf life indicated is only an estimate, and the cheese's quality may deteriorate faster depending on factors like humidity and temperature fluctuations.

By following these storage guidelines, you can confidently enjoy your Swiss cheese or Monterey Jack for up to 2 to 3 weeks after opening. Just remember to practice safe food handling, wash your hands before handling cheese, and ensure your wrapping materials and storage containers are clean. With proper care, you can make the most of your semi-hard cheeses and savor every delicious bite.

Blue cheeses like Stilton, Roquefort, and Gorgonzola can last several months when unopened and refrigerated

Blue cheeses like Stilton, Roquefort, and Gorgonzola are known for their distinct smell and taste. But how long do they last when stored in the refrigerator? Well, if left unopened and refrigerated properly, these blue cheeses can last several months.

The shelf life of blue cheese ranges from one to six months, depending on its packaging. If it's wrapped in cheese paper inside a carton package, similar to how brie is packaged, it will likely have a shorter shelf life. On the other hand, if it's sealed airtight, it will stay good for much longer. The type of packaging used can make a significant difference in how long the cheese stays edible.

While the cheese is unopened, it should retain its freshness until the date on the label and perhaps even a couple of weeks more. However, once the package is opened, it's best to finish the cheese within three to four weeks. This timeframe also applies if you buy the cheese fresh from the wheel.

To ensure the best quality, it's important to store blue cheese properly. It should be kept in the fridge, wrapped well to prevent drying out, but with some breathing room. The ideal temperature for storing blue cheese is between 46°F and 55°F (or 8°C and 13°C). This temperature range is similar to the one in which the cheese matured.

Additionally, it's recommended to keep blue cheese away from other cheeses and food items to avoid contaminating them with the mold spores from the blue cheese. When it comes to packaging, you can use cheese paper, wax paper, or parchment paper, and then place the cheese in a freezer bag. If you don't have these materials, a plastic bag or airtight container can also be used, although they are not ideal.

In summary, blue cheeses like Stilton, Roquefort, and Gorgonzola can last for several months if they remain unopened and are stored properly in the refrigerator. The specific duration depends on the packaging, but it typically falls within the range of one to six months. Once opened, it's best to consume the cheese within three to four weeks to ensure optimal freshness and quality.
