Cheddar cheese is a beloved dairy product known for its rich flavor and versatility. Whether you’re a cheese connoisseur or simply enjoy a good grilled cheese sandwich, it’s important to know how long cheddar cheese can go unrefrigerated. In this ultimate guide, we’ll explore the factors that affect the shelf life of cheddar cheese and provide you with some essential tips to ensure its freshness.

Factors Affecting Cheddar Cheese Shelf Life

Cheddar cheese, like any other perishable food, can spoil if not stored properly. Several factors influence how long cheddar cheese can go unrefrigerated:

1. Temperature: Cheese is sensitive to temperature changes. Higher temperatures can accelerate bacterial growth and cause the cheese to spoil faster.

2. Moisture: Excessive moisture can lead to the growth of mold and bacteria, which can spoil the cheese.

3. Packaging: The type of packaging plays a crucial role in preserving the freshness of cheddar cheese. Properly sealed and airtight packaging can help extend its shelf life.

How Long Can Cheddar Cheese Go Unrefrigerated?

Cheddar cheese is a semi-hard cheese that can withstand slightly higher temperatures compared to softer cheeses. However, it’s still essential to store it properly to maintain its quality. Generally, cheddar cheese can go unrefrigerated for up to four hours without significant spoilage.

If you plan to keep cheddar cheese unrefrigerated for an extended period, it’s crucial to consider the following:

1. Temperature: Ensure that the ambient temperature is below 70°F (21°C). Higher temperatures can cause the cheese to spoil more quickly.

2. Packaging: If the cheese comes in a vacuum-sealed package, it can last longer unrefrigerated. However, once opened, it should be consumed within a few hours.

3. Moisture: Keep the cheese away from excessive moisture, as it can promote the growth of mold and bacteria.

4. Storage conditions: Store the cheese in a cool, dry place away from direct sunlight and strong odors.

Tips for Properly Storing Cheddar Cheese

To maximize the shelf life of cheddar cheese, follow these tips:

1. Refrigeration: Cheddar cheese should be stored in the refrigerator at a temperature between 35°F and 40°F (1.7°C and 4.4°C). Wrap it tightly in plastic wrap or aluminum foil to prevent moisture loss and exposure to odors.

2. Cheese paper: Consider using cheese paper, which allows the cheese to breathe while still protecting it from drying out.

3. Airtight containers: If you prefer using containers, make sure they are airtight to prevent moisture and odors from affecting the cheese.

4. Avoid freezing: Freezing cheddar cheese can alter its texture and affect its flavor. It’s best to consume it before resorting to freezing.


Cheddar cheese can go unrefrigerated for up to four hours, but it’s crucial to store it properly to maintain its freshness. Factors such as temperature, moisture, and packaging play a significant role in determining its shelf life. By following the tips mentioned above, you can enjoy your cheddar cheese for longer periods without compromising its quality. Remember, when in doubt, it’s always better to err on the side of caution and refrigerate your cheddar cheese to ensure its safety and taste.
