Cheese Expiration: How Long Does Cheese Last Past Its Date?

The shelf life of cheese depends on the type of cheese and how it's stored. Harder, aged cheeses like Asiago, Parmesan, and Cheddar can last four to six months in the fridge if stored correctly. On the other hand, soft, less mature cheeses like cottage cheese, cream cheese, and mozzarella have a shorter fridge life of about one to two weeks past their expiration date due to their high moisture content. For naturally aged Cheddar cheese, it can continue to age and sharpen in the fridge, while stirred curd cheeses like Monterey Jack and Colby are not recommended for consumption after their code date.

Hard cheese can be stored unopened in the fridge for up to six months

If you want to keep hard cheese for longer than six months, it's important to store it properly. Wrapping hard cheese in wax, parchment, or cheese paper will help to maintain its moisture and keep it fresh. It should be stored in the coldest part of the fridge, and ideally in an airtight container or tightly wrapped.

Even if your hard cheese has been stored for longer than six months, it may still be safe to eat. The first thing to do is to inspect the cheese for mould. Hard cheeses can develop mould over time, especially if they have not been properly wrapped and stored. If you see any mould, simply cut it off, discarding at least 1 inch (2.5 cm) around and below the affected area, and the rest of the cheese should be safe to eat.

However, if the hard cheese has been stored for too long, it may develop other signs of spoilage. If the cheese smells sour, rancid, or like ammonia, this is a sign that it has gone bad. Similarly, if the texture has changed and the cheese has become overly dry, crumbly, or slimy, it should be discarded. A change in colour, such as yellowing or browning, can also indicate spoilage. If you're still unsure, you can try a small amount of the cheese. If it has an off or sour flavour, it has likely spoiled and should not be consumed.

Soft cheese should be consumed within one to two weeks of opening

Soft cheese is highly perishable and requires extra care when it comes to consumption past its sell-by date. While cheese can often be consumed past this date, soft cheeses like cottage cheese, cream cheese, ricotta, Brie, mozzarella, Neufchâtel, feta, Gorgonzola, and Camembert have a shorter shelf life than harder cheeses.

Soft cheeses are more susceptible to spoilage due to their high moisture content, which creates an ideal environment for bacterial growth. Therefore, it is recommended that soft cheese be consumed within one to two weeks of opening. This guideline ensures that consumers minimise their risk of foodborne illnesses associated with consuming spoiled soft cheese.

To extend the shelf life of soft cheese, it is essential to practise proper storage methods. Soft cheeses should be stored in the refrigerator, ideally in a Tupperware container or plastic jar, to limit airflow while still allowing for some ventilation. By creating a controlled environment, the growth of bacteria is hindered, and the cheese will remain edible for a longer period.

When it comes to determining whether a soft cheese has gone bad, there are several tell-tale signs to look out for. Firstly, the presence of any mould on soft cheese is a clear indication that it should be discarded entirely. Unlike harder cheeses, where mould can be cut off, soft cheeses provide an ideal environment for mould to penetrate deeper, increasing the risk of foodborne illness if consumed.

Additionally, other signs of spoilage include odd odours, a slimy texture, or a sour flavour. If the cheese exhibits any of these characteristics, it should be discarded immediately. It is also important to trust your senses; if the cheese looks, smells, or tastes "off", it is best to err on the side of caution and dispose of it.

In conclusion, soft cheese should be consumed within one to two weeks of opening to ensure food safety and maintain product quality. Proper storage methods can extend the shelf life to some extent, but consumers should always be vigilant for signs of spoilage and use their best judgement before consuming soft cheese past its prime.

Semi-hard and semi-soft cheeses last about two to four weeks after the expiry date

Semi-hard and semi-soft cheeses, such as Emmental, Gruyère, and Gouda, can be kept in the fridge for two to four weeks after their expiry date. This is because they have a higher moisture content than hard cheeses, which affects their longevity.

To ensure your semi-hard and semi-soft cheeses last the full two to four weeks, it is important to store them correctly. This involves removing the cheese from its plastic packaging and wrapping it loosely in a pliable yet breathable material, such as wax paper or cheese paper. Then, place the cheese in an airtight container and store it in the fridge.

It is worth noting that the cheese will likely start to decline in quality before the two to four weeks are up, so it is best to only buy cheese for the week ahead. Additionally, always use your senses to determine if the cheese is still good. Look out for any mold growth, discoloration, or unusual smells, and if the cheese exhibits any of these signs, it should be thrown away.

Stirred curd cheeses like Monterey Jack, Colby, and Pepper Jack should not be eaten after the expiry date

It is important to note that stirred curd cheeses like Monterey Jack, Colby, and Pepper Jack should not be eaten after their expiry date. These cheeses have specific storage guidelines to ensure optimal freshness and food safety.

For unopened Monterey Jack cheese, the original packaging can be maintained when refrigerating. To maximize shelf life, do not open the package until you are ready to use it. Properly stored, an unopened chunk of this cheese will last for about six months in the refrigerator, even beyond its "sell-by" or "best-by" date. If you notice mold on an unopened chunk, cut away at least one inch around and below the moldy area and re-cover the cheese in fresh wrap. However, if mold appears in shredded, sliced, or crumbled Monterey Jack cheese, discard the entire package.

To further extend the shelf life, you can freeze Monterey Jack cheese. Cut the cheese into portions no larger than half a pound each and wrap them tightly in heavy-duty aluminum foil or plastic freezer wrap, or place them in a heavy-duty freezer bag. Properly stored, it will maintain its best quality for about six to eight months in the freezer but will remain safe beyond that timeframe. When defrosting, gradual thawing yields the best results. Thaw the cheese in the refrigerator, and it can be kept for an additional three to four days before using it. Frozen cheese may become crumbly and lose some flavor, so it is best suited for cooked dishes like sauces, soups, and casseroles.

Colby cheese, an American original, is known for its mellow flavor and distinct texture. When unopened and stored in the refrigerator, Colby cheese generally has a shelf life of one to two months, which can be extended beyond its printed "sell-by" or "best-by" date if proper storage conditions are maintained. Once opened, the shelf life decreases to three to four weeks in the refrigerator. If stored in the freezer, Colby cheese will maintain its best quality for about six months. As with any perishable food, it is crucial to handle and store Colby cheese correctly to ensure safety and maintain its quality.

Pepper Jack cheese, a beloved blend of Monterey Jack infused with spicy peppers, also has specific storage guidelines. Unopened Pepper Jack cheese stored in the refrigerator maintains peak quality for about one to two months past its sell-by date. Refrigeration is crucial to preserve its texture and flavor. It should never be left unrefrigerated for extended periods. At room temperature, unopened Pepper Jack cheese is safe for a few hours, but refrigeration is necessary for longer storage to prevent spoilage.

In summary, it is important to adhere to the expiry dates and proper storage conditions for stirred curd cheeses like Monterey Jack, Colby, and Pepper Jack. By doing so, you can ensure the freshness, quality, and safety of these cheeses while also avoiding potential health risks associated with consuming spoiled cheese.

If mould appears on hard cheese, cut off at least 1 inch around and below the spots

If you spot mould on hard cheese, it's important to act quickly to salvage the rest of the cheese. The first step is to cut off at least 1 inch (2.5 cm) around the mouldy spots, being sure to go below the spots as well. This generous divot will ensure that you remove any mould roots, which can grow deeper into softer cheeses. While it may seem wasteful, this measure will help preserve the rest of the cheese.

It's important to note that this advice applies specifically to hard cheeses. For softer, fresh cheeses like mozzarella, burrata, ricotta, mascarpone, paneer, or feta, it's best to discard the entire block if mould is present. These types of cheeses are more perishable and susceptible to decay.

When dealing with mould on hard cheese, it's crucial to use a clean, sharp knife to cut away the affected areas. Ensure that you don't spread the mould spores to other parts of the cheese. Wash the knife thoroughly after use, and consider covering the cut surface of the remaining cheese with cling film or storing it in an airtight container to prevent further contamination.

After removing the mouldy sections, examine the cheese for any other signs of spoilage, such as discolouration, sliminess, or an unpleasant odour. If the cheese appears and smells normal, it's likely safe to consume. However, if you have any doubts or concerns about the cheese's safety, it's always best to err on the side of caution and discard it.

Additionally, it's worth mentioning that while cutting away mould from hard cheese can extend its lifespan, proper storage practices are essential to prevent mould growth in the first place. Wrapping cheese properly and storing it in a suitable environment will help maintain its quality and freshness.
