Green Coffee

Green coffee refers to raw, unroasted coffee beans in their natural state after processing at origin. These beans are dense, pale green to yellowish in color, and carry a grassy, slightly vegetal aroma that bears little resemblance to the rich smell of roasted coffee. Green coffee is the commodity traded on global markets and the raw material that roasters transform into the brown beans you grind and brew.

After harvesting, coffee cherries are processed — washed, natural, or honey — to remove the fruit layers surrounding the seed. The resulting green beans are dried to a moisture content of around 10–12%, then sorted by size, density, and defect count before being bagged in burlap or GrainPro-lined sacks for export. Proper storage matters: green coffee should be kept in a cool, dry environment away from direct sunlight to preserve freshness, though it is far more shelf-stable than roasted coffee.

Home roasters buy green coffee in small lots from specialty importers, often at a significant discount compared to pre-roasted beans. A single origin lot might cost 40–60% less per pound when purchased green, making home roasting an economical hobby for serious coffee enthusiasts. Green beans also allow roasters to experiment with roast profiles and highlight different flavor characteristics from the same lot.

Quality grading varies by country, but the Specialty Coffee Association uses a 100-point cupping scale where beans scoring 80 or above qualify as specialty grade. Defect counts, screen size, and cup quality all factor into the grade assigned to a green coffee lot.
