Hard Cheese: How Long Does It Last?

Hard cheeses, such as parmesan, cheddar, and gouda, are low in moisture, making it difficult for bacteria to flourish. This gives them a longer shelf life than soft cheeses. According to experts, hard cheeses can last about four weeks in the refrigerator once opened, while unopened packages can last about six months.

Hard cheese can be stored in the fridge for up to four weeks after opening

Hard cheese is a treat for many, but it can be a costly one. So, it is important to know how to store it properly to make it last longer. According to cheese experts, hard cheese can be stored in the fridge for up to four weeks after opening. This is because hard cheeses are low in moisture, which makes it difficult for bacteria to flourish.

To ensure your hard cheese lasts the full four weeks, follow these steps:

• 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.

It is worth noting that hard cheeses, such as aged cheddar, aged Gouda, and Parmigiano Reggiano, will last much longer if stored in the fridge, even when unopened. Unopened packages of hard cheese can last up to six months in the refrigerator.

When it comes to determining if your hard cheese has gone bad, look out for signs of mold. If you spot any, simply cut off at least one inch around and below the moldy spots, and the rest of the cheese should still be good to eat. However, if you see red or black mold, it is best to discard the entire cheese as these could indicate a more serious issue.

Unopened hard cheese can be stored in the fridge for up to six months

Hard cheeses, such as aged cheddar, aged gouda, and parmesan, are low in moisture, making it difficult for bacteria to flourish. This means that unopened hard cheese can be stored in the fridge for up to six months.

Once opened, a package of hard cheese will typically last about four weeks in the refrigerator. However, if mould forms on the outside, it can be cut off, and the rest of the cheese can be safely consumed. Hard cheeses can be stored in the refrigerator by removing them from their plastic packaging and wrapping them loosely in cheese paper or wax paper before placing them in an airtight container.

It is important to note that the shelf life of hard cheese may vary depending on factors such as the age of the cheese when purchased, whether it has been opened, the amount of moisture in the cheese, and the storage conditions.

Additionally, while hard cheese can be frozen, it may taste slightly different after being thawed.

Hard cheese can be frozen to extend its shelf life

When cheese is frozen, any moisture in the cheese becomes frost crystals. Once the cheese is thawed, the water is released, and the cheese dries out. Previously frozen cheese often becomes more crumbly and can have an unpleasant, mealy texture. The lower the moisture content in the cheese, the less noticeable these changes will be, which is why hard and semi-hard cheeses are ideal for freezing. Freezing can also inactivate microbes in cheese, such as bacteria, yeasts, and mold, which helps extend its shelf life.

However, freezing doesn't kill these microbes; it only damages them. Once the cheese thaws, the microbes can become active again. In the case of ripened cheeses like blue cheese and Camembert, live mold and bacteria populations are essential to give these varieties their distinctive textures and flavors. Freezing can damage these microbes and stop the cheeses from ripening properly when thawed, potentially decreasing their overall sensory quality.

If you decide to freeze hard cheese, there are several steps you can take to ensure the least loss of quality. First, portion the cheese into quantities you're likely to use at one time. Wrap the cheese in foil or cheese paper, and separate slices with parchment paper. Then, place the wrapped cheese in an airtight container or bag. Freeze the cheese as rapidly as possible to prevent the formation of large ice crystals, which will affect the taste and texture.

Hard cheese can be kept frozen indefinitely, but for the best quality, it's recommended to use it within 6–9 months. Frozen cheese should be thawed slowly in the refrigerator to prevent the growth of harmful bacteria. Once thawed, the cheese can be used in cooked dishes where changes to texture are less noticeable, such as sauces, pizzas, grilled cheese sandwiches, casseroles, or soups.

Hard cheese can be identified by its low moisture content

Hard cheeses, such as aged cheddar, aged gouda, and parmigiano reggiano, have low moisture content, which makes it difficult for bacteria to flourish. This means that hard cheeses can last a long time once opened—about four weeks in the refrigerator, according to experts. Unopened packages of hard cheese can last about six months, according to the USDA.

To extend the shelf life of hard cheese, it is important to store it properly. This involves removing the cheese from its plastic packaging and wrapping it loosely in a breathable material, such as cheese paper or wax paper. The wrapped cheese is then placed in an airtight container and stored in the refrigerator.

It is also important to note that hard cheeses can develop mold over time. However, unlike soft cheeses, the mold in hard cheeses does not usually penetrate beyond the surface. Therefore, it is generally safe to cut off the moldy part of a hard cheese and consume the rest.

It's important to note that hard cheeses will lose moisture and change over time, so they should be consumed as soon as possible after purchasing for the best quality. Additionally, while hard cheeses can be frozen, freezing will alter their taste.

When it comes to determining if your hard cheese has gone bad, look for signs of mold. If you see specks of blue or green surface mold, simply cut off at least 1 inch (2.5 cm) around and below those 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 mold but calcium lactate crystals.
