Semi-hard or hard cheeses can be sealed in the refrigerator and kept fresh for almost 4-8 weeks. Hard dry cheese grated needs to be placed in an airtight container and refrigerated so that the shelf life can be up to 2 weeks role, if you want to keep it for a long time, this needs to be frozen. Spread vinegar on top of the cheese and wrap the cheese in paper towels and store in the refrigerator.
