Always store cheese in your refrigerator which approximates the temperature of aging rooms. Air helps mold grow on cheese. So the best way to protect cheese is to keep it wrapped tightly in an air-tight container. If you get a little mold on the outside does not mean that your cheese is no good, but make sure you cut that off before usage. The English say “If mold won't eat your cheddar, it can't taste very good”. Before melting cheese, don’t forget to bring it to room temperature and always use low heat to help prevent toughening and separation of oils and liquids. Most ripened or aged cheese is low in moisture content and can be frozen without any drastic flavor and texture changes. If cheese is frozen for several months, it may dry out and become somewhat crumbly when thawed. So remember these important tips the next time you bring home some ricotta, blue cheese or mozzarella.
