Sharp cheddar cheese is a variety of cheddar that has been aged for a longer period, resulting in a tangy, nutty taste. However, if sharp cheddar cheese suddenly tastes bad, it may be due to several factors. One possible reason could be improper storage conditions, such as temperature and humidity, which can lead to the growth of bad bacteria and mold, affecting the taste. Additionally, the aging process of cheddar cheese can also impact its flavor, with longer-aged cheeses developing a stronger, sharper taste that may be unpalatable to some. Furthermore, individual taste preferences and sensitivity to certain flavors can also influence the perception of sharpness in cheddar cheese. It is worth noting that the quality of the cheese, as well as any added ingredients or preservatives, can also play a role in the overall taste experience.

Sharp cheddar's taste and texture change as it ages
The sharpness of cheddar cheese is directly related to how long it has been aged. Cheddar cheese is a natural cheese that is relatively hard and sometimes sharp-tasting. It originates from the village of Cheddar in Somerset, South West England, and is now produced worldwide. The cheese gets its distinctive flavour and texture from the aging process.
Freshly made cheddar cheese is wrapped in cloth and left to rest for a few days. During this time, the cheese releases whey, and mould starts to grow on its surface. It is then moved to a temperature-controlled room, where it will age for a few months to several years. The longer the cheese ages, the sharper and more robust the flavour becomes. The aging process also affects the texture, with older cheeses becoming firmer and more crumbly.
The term "sharp" refers to the changes in taste and texture that occur as cheddar ages. This process typically takes anywhere from two months to a year or more, depending on the desired sharpness. During aging, cheddar loses moisture, transforming from smooth and creamy to firm with hard, salt-like crystals. These crystals are formed when lactose breaks down into lactic acid, which binds with calcium ions to create calcium lactate crystals.
The sharpness of cheddar is associated with the levels of bitter peptides in the cheese, contributing to the overall perception of its flavour. The texture of aged cheddar is described as firm, with farmhouse traditional cheddar being slightly crumbly. It may also contain large cheese crystals of calcium lactate if matured for longer than six months.

The cheese may have been improperly stored
Freezing cheese can also alter its composition and texture. While some hard cheeses like Parmesan and pecorino freeze and thaw well, young, semi-soft cheeses like mild Cheddar can become grainy and crumbly when frozen.
It is important to note that the aging process also affects the taste of cheddar cheese. As cheddar ages, it loses moisture, becoming firmer with salt-like crystals. These crystals form when lactose breaks down into lactic acid, which then binds with calcium ions. The longer the aging process, the sharper the taste of the cheddar. Therefore, the sudden change in the taste of cheddar cheese could be due to improper storage conditions affecting the aging process, resulting in an accelerated development of sharpness.
To determine if the cheese has gone bad, it is advisable to use your senses, particularly sight, smell, and taste. Mild cheeses like Monterey Jack or American that develop a strong smell, similar to blue cheese or Limburger, should be discarded. A spoiled cheese may exhibit an overly bitter, sour, or musty taste. It is important to store cheese properly, maintaining the right temperature and humidity levels, to prevent spoilage and preserve its intended taste.

Freezing sharp cheddar can change its texture
The degradation of texture will be noticeable, especially if the cheese is eaten plain. Therefore, it is recommended to use frozen sharp cheddar in cooked dishes where changes in texture are less noticeable, such as sauces, casseroles, or grilled cheese sandwiches. Freezing sharp cheddar can also slightly alter its taste, but this change may not be discernible when used as an ingredient in cooked dishes.
To minimize texture changes, it is crucial to properly prepare and store the cheese before freezing. This includes portioning the cheese into quantities that will be used at one time, as freezing and thawing multiple times can affect the texture. The cheese can be grated or sliced before freezing, and then wrapped securely in airtight packaging to prevent freezer burn and absorption of odors.
Additionally, double-wrapping with plastic wrap and aluminum foil can provide extra protection. It is also recommended to freeze the cheese as rapidly as possible to prevent the formation of large, disruptive ice crystals. When ready to use, the cheese should be thawed slowly in the refrigerator, ideally overnight, to allow the cheese to retain some of its moisture and texture.

The cheese may have gone bad
If your Easy Cheese Sharp Cheddar has suddenly started to taste bad, it may have gone off. Cheddar is a hard cheese, and hard cheeses have a sharper, tangier taste than mild cheeses. The sharper taste is due to the aging process, during which cheddar loses some of its moisture, becoming firmer with hard, salt-like crystals. However, if not stored correctly, the aging process can cause the cheese to go bad.
Freezing cheese changes its composition, and while hard cheeses like Parmesan and pecorino freeze and thaw quite well, young, semi-soft cheeses like mild cheddar can become grainy and crumbly when frozen. Cheddar should be stored in the refrigerator at a temperature of 5-8 degrees Celsius. An environment that is too humid and hotter than 45 degrees Fahrenheit can cause bacteria and mold to grow on the cheese.
If a mild cheese has developed a strong flavor, it has likely gone bad. Spoiled cheese will taste overly bitter or sour, or have a musty, moldy flavor. A spoiled mild cheese may smell like blue cheese or Limburger, while a spoiled Camembert may smell like ammonia. If a cheese has a much stronger version of its usual smell, it has probably gone bad.
If you are unsure whether your cheese has gone bad, it is better to be safe than sorry and throw it away. While a healthy immune system may mean that consuming a small amount of spoiled cheese will only cause a bit of indigestion, it is not worth the risk.

The cheese may have been exposed to bad bacteria or mould
The sudden change in the taste of Easy Cheese Sharp Cheddar could be attributed to several factors, one of which is exposure to bad bacteria or mould. Cheese is highly susceptible to mould growth, and improper storage can accelerate this process. If the cheese has been exposed to air for extended periods, the surface may have been invaded by mould spores, which, over time, can multiply and spread throughout the cheese.
Moulds can significantly alter the taste of cheese, and not always in a desirable way. While some moulds are used intentionally in cheesemaking to create distinct flavours and textures, such as in Blue Cheese or Brie, unintended mould growth can compromise the original taste of the cheese. The presence of mould may explain why your Easy Cheese Sharp Cheddar now has an unpleasant taste.
It's important to note that not all moulds are harmful, and some may be safe to consume even if they alter the flavour of the cheese. However, it can be challenging to determine which moulds are safe and which are not just by visual inspection. Certain moulds, like Aspergillus niger, a dark black-grey mould, can be toxic and should be avoided.
To prevent mould growth and maintain the quality of your cheese, proper storage is essential. Avoid using plastic wrap, as it can trap moisture, creating an ideal environment for mould and bacteria to thrive. Instead, opt for breathable storage materials like parchment paper, cheese wraps, or cheese bags. Additionally, always use clean utensils and wrappers when handling the cheese to minimise the transfer of bacteria.
If you notice any visible mould on the surface of your Easy Cheese Sharp Cheddar, it's best to discard it entirely. While you might be tempted to cut off the mouldy portion and consume the rest, it's difficult to guarantee that the unaffected areas are entirely safe. To avoid any potential health risks, it's recommended to dispose of the cheese and maintain proper storage practices for future purchases.
