Green coffee beans are the raw seeds of coffee cherries that have been separated or “processed” and have yet to be roasted. All of a coffee’s taste and flavor potential is held within this green seed. This potential is ultimately unleashed through roasting the green coffee.
Once the cherries are harvested from coffee trees, they are processed in several ways, depending on the coffee’s origin. Three of the most common approaches to processing are: washed, semi-washed and naturally-processed. The end result of each is that the fruit of the coffee cherry is stripped away, leaving only the green coffee. Each method of processing contributes to the final taste you’ll experience when you drink it. But before it’s enjoyed in a cup of coffee, the beans have to be roasted.
Green coffee beans can look and taste differently depending on where they were grown, the type (varietal) of the coffee tree it came from, and how it was processed.
