Grade 1 Robusta Coffee Beans vs Grade 2: What Importers Need to Know
Grade 1 robusta coffee beans are larger (screen 16 or 18) and cleaner, with black and broken beans typically capped at 2% and foreign matter at 0.5% or less. Grade 2 is smaller (screen 13) and usually allows about 5% black and broken beans, 1% foreign matter and up to 13% moisture. In practice, Grade 1 is a roaster's coffee and Grade 2 is mostly a soluble manufacturer's coffee.
