What is the name of the layer that is found just inside the parchment of the coffee bean?

The layer found just inside the parchment of the coffee bean is known as the Silver Skin. This skin is a thin, papery layer that remains on the bean even after the coffee cherry has been processed and dried. It plays a role in protecting the green coffee bean during the processing phase but is usually removed during roasting.

Understanding the significance of the Silver Skin can enhance your knowledge of coffee processing. It does not contribute significantly to the flavor of the coffee, but its presence is important for maintaining the quality of the bean during transport and storage. When coffee is roasted, the Silver Skin can sometimes become brittle and may even blow away, but it does not alter the essential characteristics of the coffee itself. This contrast with the other options, such as the pulp, which is the fleshy part of the coffee cherry, or mucilage, a sticky substance that aids in processing, illustrates the unique role of the Silver Skin. The term "green bean" refers to the coffee bean before roasting, but it encompasses the entire bean rather than a specific layer.
