What grows on a old cheese?

It depends on the type of cheese and how it's stored. Here's a breakdown:

Natural Mold:

* Blue Cheese: This is the most common example of intentional mold growth on cheese. Blue cheese is inoculated with *Penicillium Roqueforti*, which creates the characteristic blue veins and pungent flavor.

* Other Mold-Ripened Cheeses: Some other types of cheese, like Brie, Camembert, and Roquefort, are also ripened using specific mold cultures.

Unwanted Mold:

* Unintentional Mold: If cheese is stored improperly, it can develop unwanted mold growth. This can be caused by:

* Moisture: Too much moisture can encourage mold.

* Warm Temperatures: Warm temperatures speed up bacterial and mold growth.

* Exposure to Air: Open air allows mold spores to settle on cheese.

Important:

* Don't eat moldy cheese unless it's intentionally ripened with mold.

* If mold appears on a cheese that's not meant to have it, it's best to throw the whole thing away. This is because the mold might have spread throughout the cheese, even if it's only visible on the surface.
