Planting and Harvesting
The cultivation of coffee beans begins with the planting of seeds or seedlings. The young coffee plants are carefully nurtured to ensure healthy growth. It takes several years for the plants to mature and produce their first harvest. Once the coffee cherries have ripened, they are ready for harvest. This is a labor-intensive process, often involving hand-picking to ensure only the ripest cherries are selected.
After harvest, the coffee cherries go through various processing methods to prepare them for roasting. The three primary processing methods are washed, natural, and honey. The washed method involves removing the outer skin and pulp, fermenting the beans to remove the remaining mucilage, and thoroughly washing them. The natural method involves drying the cherries whole, allowing the beans to ferment within the fruit. The honey method is a combination of the washed and natural methods, with varying degrees of mucilage remaining on the beans.
Drying and Aging
Once the processing is complete, the coffee beans need to be dried to reduce moisture content. This is typically done by spreading the beans out on large patios or using mechanical dryers. Proper drying ensures the beans retain their flavor and prevents spoilage. Some coffee beans may undergo an additional step called aging, where they are stored for a period of time to enhance their flavor before roasting.
