Cheddar can be left out of the fridge for up to eight hours
Cheddar is a hard cheese, and as such, it can be left out of the fridge for up to eight hours and remain safe to eat. This is because hard cheeses have a lower moisture content, which discourages bacterial growth. In fact, research has shown that most hard cheeses can slow the growth of bacteria, so the chance of foodborne illness caused by consuming them is extremely low.
However, while cheddar can be left out for eight hours and still be safe to eat, it may start to dry out and lose its quality after four or five hours. So, from a quality perspective, it's best to put any leftover cheddar back in the fridge as soon as you're finished eating it.
When storing cheddar in the fridge, it's important to keep it in a quality airtight container to ensure it doesn't dry out. If exposed to air, it won't last as long.
It's also worth noting that the two-hour guideline for perishable foods does not apply to all cheeses. Softer cheeses, like cream cheese or processed cheeses, can be left out for no more than two hours, while harder cheeses like cheddar can last for a much longer period of time, even several weeks, without refrigeration.

Soft cheeses like mozzarella or cream cheese should be discarded after two hours
Soft cheeses, such as mozzarella, cream cheese, cottage cheese, and fresh mozzarella, are more perishable than hard cheeses like cheddar. This is due to their higher moisture content, which encourages bacterial growth. As a result, soft cheeses should not be kept out at room temperature for more than two hours.
The U.S. Department of Health advises against keeping perishable food out of the fridge for more than two hours. This is particularly important for soft cheeses, as they are highly perishable and susceptible to spoilage and bacterial growth. If soft cheeses are left out for longer than two hours, they should be discarded.
Hard cheeses, on the other hand, can be left out for up to eight hours at room temperature. This is because they have a lower moisture content, which makes them less prone to bacterial growth. However, it is still recommended to refrigerate them after four hours to maintain quality.
It is important to note that the shelf life of soft cheese is influenced by various factors, including the type of cheese, processing method, packaging date, exposure to heat, and storage conditions. Proper food storage is crucial to extending the shelf life of soft cheeses. They should be stored in the refrigerator at 40°F or lower and kept in a tightly closed container or wrapped in plastic to maintain freshness and prevent contamination.
Additionally, soft cheeses should not be kept at room temperature for extended periods, as they will quickly degrade as their temperature increases. For optimal food safety and quality, soft cheeses like mozzarella and cream cheese should be refrigerated and consumed within two hours of being left out at room temperature.

Hard cheeses like cheddar will last longer as they have a lower moisture content
The lower moisture content of hard cheeses like cheddar makes them less susceptible to bacterial growth. As a result, they can be left out at room temperature for longer periods without spoiling. According to the Dairy Farmers of Wisconsin, hard cheeses can be left out for up to four hours and still be safe to eat. However, it is important to check for signs of spoilage, such as an unpleasant smell, a slimy surface, dark spots, dryness, cracks, or mould. If any of these signs are present, it is best to discard the cheese.
Additionally, the aging process of hard cheeses contributes to their longer shelf life. Hard cheeses are typically aged for longer periods, ranging from two to 36 months, or even longer. This extended aging reduces the risk of bacterial growth and helps preserve the cheese.
It is worth noting that while hard cheeses can be left out at room temperature for a few hours, their taste, flavour, and texture may still be impacted. Hard cheeses that are left out for extended periods may become drier and lose their exquisite taste. Therefore, it is generally recommended to store hard cheeses in the refrigerator to maintain their freshness and prevent spoilage.
In summary, hard cheeses like cheddar can last longer outside of refrigeration due to their lower moisture content, which inhibits bacterial growth. However, it is important to monitor the cheese for any signs of spoilage and be aware that its quality may deteriorate over time. For optimal taste and food safety, refrigeration is still recommended.

Cheddar slices may become greasy or oily if left out of the fridge
Cheddar cheese is a complex food product composed of proteins, fats, and water. Cheddar slices may become greasy or oily if left out of the fridge due to the breakdown of fat molecules within the cheese. This phenomenon is more likely to occur in cheddar cheese with a higher fat content. When left at room temperature, the fat molecules in cheddar cheese can begin to break down and separate from the proteins, forming small droplets that can coalesce into larger pools of oil, resulting in the greasy appearance and texture.
It is important to note that while the cheese may appear greasy or oily, it is still safe to consume. The oiliness is caused by the natural breakdown of fat within the cheese and does not indicate spoilage. However, if the cheese has been left out of the refrigerator for an extended period, it is essential to consider other factors that may affect its safety.
According to food safety guidelines, cheese can typically be left out at room temperature for up to 4 to 8 hours, depending on the type, and remain safe to eat. Hard cheeses like cheddar have a lower moisture content, allowing them to sit out at room temperature for up to 8 hours. However, it is recommended to refrigerate leftover cheese as soon as possible to maintain its quality and freshness.
To prevent cheddar cheese from becoming greasy or oily when left out of the refrigerator, it is advisable to follow proper storage practices. Cheddar cheese should be wrapped well and stored in the refrigerator. If the cheese has been left out for an extended period and has become dry, it can be wrapped in foil and stored in the freezer for later use in recipes.
Additionally, when melting cheddar cheese, there are techniques to minimize oiliness. Using a lower-fat cheese, melting slowly over low heat, and avoiding overheating can help prevent the fat molecules from separating and reduce the greasy appearance.

Cheddar cheese was invented before refrigerators
Cheddar cheese is a hard cheese with a unique, rich flavour that ranges from mild to extra sharp. It originates from the village of Cheddar in Somerset, southwest England. The earliest references to cheddar cheese date back to 1170, and King Henry II purchased 10,240 lbs of it in that year.
Cheddar cheese was born out of necessity, as a way to preserve surplus milk before the invention of refrigeration. The process of cheesemaking was perfected in the Cheddar area, where the Cheddar Gorge provided the ideal humidity and steady temperature for maturing the cheese. Cheesemakers discovered that pressing the fresh curd to remove moisture made the cheese last much longer.
The first home electric refrigerator was introduced much later, in 1913, by American Fred W. Wolf. However, it was the 1927 "Monitor-Top" refrigerator, designed by a team of engineers at General Electric, that became the first commercially successful model. This breakthrough in refrigeration technology made it practical and affordable for households to safely store perishable foods without relying on ice deliveries or iceboxes.
So, while the exact date of cheddar cheese's invention is unknown, it is clear that it predates the modern electric refrigerator by several centuries.
