The shelf life of cheese once it has been opened can vary depending on the type of cheese and storage conditions. While the "best by" date is a guideline for peak quality, it doesn't necessarily mean that the cheese is unsafe to eat immediately after that date. Here are some general guidelines for different types of cheese:
Hard cheeses (e.g., cheddar, Parmesan): Hard cheeses generally have a longer shelf life compared to soft cheeses. Once opened, they can typically last 1 to 2 months in the refrigerator if stored properly. Make sure to reseal the cheese tightly after each use and consider wrapping it in wax paper or parchment paper before resealing it in plastic wrap or an airtight container.
Soft cheeses (e.g., brie, camembert): Soft cheeses have a higher moisture content and are more perishable. Once opened, they typically last 1 to 2 weeks in the refrigerator. Wrap them in wax paper or parchment paper, and then place them in an airtight container to help maintain freshness.
Semi-soft cheeses (e.g., gouda, blue cheese): Semi-soft cheeses fall somewhere between hard and soft cheeses in terms of shelf life. Once opened, they generally last about 2 to 3 weeks in the refrigerator. As with other cheeses, reseal them tightly and use airtight containers for storage.
Remember, these are general guidelines, and the actual shelf life may vary depending on factors like the cheese's condition when purchased and the temperature and humidity of your refrigerator.
To ensure the cheese remains safe to eat, it's essential to monitor it for any signs of spoilage, such as mold growth, off smells, or changes in texture. If you notice any of these signs, it's best to discard the cheese.
If you have a large quantity of cheese that you won't be able to consume before it goes bad, consider freezing portions of it. Freezing can extend the shelf life of cheese, but it may alter the texture somewhat, making it more suitable for cooking rather than eating as is. When freezing cheese, wrap it tightly in plastic wrap and place it in a freezer-safe container to protect it from freezer burn and absorb odors from other foods. Thaw frozen cheese in the refrigerator before using it.
