What You'll Learn

Aged cheeses
While soft or runny cheeses like goat cheese, cottage cheese, or cream cheese need to be refrigerated, harder, drier cheeses may not. This is because they have a very low water content, so they are less likely to spoil when left out.
Whether a cheese needs to be refrigerated or not also depends on whether it is sealed or grated. For example, processed cheeses like American cheese don't need to be refrigerated either, at least until you open them. Grated cheese will spoil faster than blocks of the same cheese.

It is worth noting that while processed cheeses may not require refrigeration, they will last longer if kept refrigerated. This is especially true for grated cheese, which will spoil faster than a block of cheese.

Some processed cheeses may have different storage requirements depending on the brand or the ingredients used. Therefore, it is important to read the label carefully to ensure the cheese is stored properly.

Soft cheeses
Soft or runny cheeses like goat cheese, cottage cheese, or cream cheese need to be refrigerated for safety. These cheeses are called "fresh" cheeses, and are either not aged at all or only for a short amount of time, so they spoil faster.
While soft cheeses are generally considered perishable and require refrigeration, there are a few exceptions. Some soft cheeses, such as mozzarella, are packaged in brine or whey, which helps to preserve them and extend their shelf life. These types of soft cheeses can be stored at room temperature until they are opened, after which they should be refrigerated.
It is also worth noting that some soft cheeses, such as ricotta or mascarpone, have a higher moisture content and are more perishable than others. These types of soft cheeses should always be refrigerated and consumed within a few days of opening to ensure freshness and safety.
In summary, while most soft cheeses require refrigeration, there are a few exceptions, such as packaged mozzarella or unopened soft cheeses. However, for the most part, soft cheeses are perishable and should be kept refrigerated to ensure freshness and safety.
