Questions buyers ask
What is EK-1 robusta?
In Sumatra's coffee trade, EK-1 usually means standard export lots: mixed bean sizes above a minimum screen, sold by defect grade. Ours are screen 13 up, in Grades 1 to 5. Some exporters use EK-1 more broadly, as a label that also covers ELB lots, so always check the screen and grade in the contract.
What does ELB mean?
ELB stands for extra large beans, sorted by size. Ours are screen 18 up, at 350 to 450 beans per 100 g, in Grades 2 to 3.
What is triage coffee?
Triage is the trade term for the smaller, broken and defective beans separated during sorting. Our industrial grade is SNI Grade 6, sold to soluble (instant) coffee manufacturers and for extraction. It is not a roasting grade.
