How long is the shelf life of cheesecake?

* How it's stored: Refrigerated cheesecake will last longer than unrefrigerated cheesecake.

* The type of crust: Graham cracker crusts tend to get soggy faster than other types of crusts.

* The filling: Cheesecakes with a higher fat content will generally last longer.

Here are some general guidelines:

* Refrigerated:

* Freshly made cheesecake: 3-5 days

* Store-bought cheesecake: Check the "best by" date on the package, but generally 5-7 days.

* Frozen:

* Homemade cheesecake: Up to 2 months

* Store-bought cheesecake: Up to 3 months

Tips for extending the shelf life of cheesecake:

* Store it in an airtight container: This will help to prevent the cheesecake from drying out.

* Wrap it tightly with plastic wrap: This will also help to prevent the cheesecake from drying out.

* Don't freeze it for too long: Freezing can affect the texture of the cheesecake.

* Thaw it in the refrigerator: Don't thaw it at room temperature, as this could cause bacteria to grow.

Signs that your cheesecake has gone bad:

* Mold: This is the most obvious sign that your cheesecake has gone bad.

* Off odor: The cheesecake may smell sour or rancid.

* Changes in texture: The cheesecake may become watery or crumbly.

It's always best to err on the side of caution and throw away any cheesecake that you're not sure about.
