Green facings refer to the green-colored outer layer of a cheese, often made from natural ingredients like herbs or vegetable extracts. This layer can enhance the cheese's flavor and appearance, making it visually appealing. The green color is typically associated with specific types of cheese, such as Gorgonzola or Havarti, which may have added ingredients like spinach or basil. In addition to flavor, green facings can also serve a protective function, helping to preserve the cheese's freshness. The outer layer can act as a barrier against mold and bacteria, ensuring that the cheese remains safe to eat. This practice is common in various cheese-making traditions around the world.
