All of our wedges of cheese are labeled on the back with a sell-by date. The cheese will be good for 2-4 weeks after this date. After a week or two, the cheese forms a thin film of mold on the surface. This is simply the good molds and bacterias that are naturally in the cheese and does not affect the quality. When you are ready to eat the cheese, simply shave off the surface with a sharp knife. Once you open the cheese and cut into it, save the rest by wrapping it in wax paper or saran wrap. The marinated feta and labneh is covered in oil, which serves as a natural preservative and allows the cheese to ship and travel unrefrigerated for a week. It will keep in your refrigerator for at least 6 months. Once you use some of the cheese, store the remainder by pushing the cheese down with a spoon to ensure it is submerged in the oil and store it in a refrigerator. The Blue and Brie cheeses will last for a couple of months after purchase and just get stronger with age.
