Feta cheese only lasts about a week after its printed expiration date in the refrigerator, and it does not freeze well, although it can be frozen for up to 6 months. Feta is a semi-soft cheese, which doesn't last as long as other cheeses.
Factors that affect the shelf life of cheese include the type of cheese it is, the processing method, its exposure to heat and the storage method. Proper storage includes a refrigerator set to temperatures below 40 degrees Fahrenheit; when not stored properly, a soft cheese will spoil quickly. Although feta cheese can be frozen for up to 6 months, freezing it changes the texture and consistency of the cheese. These changes make it grainy and drain some of the taste as well.
