How Does the ECX Grading System Work?
Ethiopian coffee is graded by the Ethiopian Commodity Exchange (ECX), which established a standardized system to classify coffee based on two primary factors: physical defects and cup quality. This dual assessment ensures that grades reflect both the visual appearance of the green beans and their actual taste in the cup.
For specialty coffee buyers, understanding this system is essential for making informed purchasing decisions and communicating quality expectations with Ethiopian exporters.
What's the Difference Between Grade 1 and Grade 2?
| Criteria | Grade 1 | Grade 2 |
|---|---|---|
| Defects per 300g | 0-3 | 4-12 |
| Cup Score (SCA) | 85+ | 80-84 |
| Specialty Classification | Yes | Yes (lower tier) |
| Screen Size | 15+ dominant | 13-15 mixed |
| Moisture Content | 9-12% | 9-12% |
| Premium Pricing | Highest tier | Mid-premium tier |
Grade 1: Premium Specialty
Grade 1 Ethiopian coffee represents the highest quality tier available. These lots undergo rigorous hand-sorting and cupping evaluation to meet the strictest standards.
Grade 1 Requirements
- Maximum 3 defects per 300g sample
- Zero primary defects (full black, full sour, dried cherry)
- SCA cupping score of 85 or higher
- Uniform screen size (typically 15+)
Best for: Roasters focused on single-origin offerings, competition coffees, and premium retail programs where visual appeal and cup complexity are paramount. We hold Grade 1 washed Yirgacheffe lots in this bracket, alongside Guji Grade 1 naturals.
Grade 2: Quality Commercial-Specialty
Grade 2 coffees still qualify as specialty coffee under SCA standards while offering more accessible pricing. They represent excellent value for roasters who prioritize cup quality over perfect visual uniformity.
Grade 2 Requirements
- 4-12 defects per 300g sample
- No more than 3 primary defects
- SCA cupping score of 80-84
- More screen size variation acceptable
Best for: Blend components, espresso programs, larger volume orders, and roasters where cup quality matters more than bean appearance. Sidamo Grade 2 lots are the usual choice here.
What Are the Coffee Defect Categories?
Not all defects are equal. The ECX system distinguishes between primary defects (severe, cup-affecting) and secondary defects (less impactful).
Full Black
Primary (severe)Completely black beans from over-fermentation or fungal infection
Full Sour
Primary (severe)Over-fermented beans with distinctly sour taste
Dried Cherry/Pod
PrimaryUnprocessed dried cherry attached to bean
Large Stones
PrimaryForeign material that can damage equipment
Partial Black
SecondaryPartially blackened beans
Partial Sour
SecondaryPartially fermented with slight sour notes
Floaters
SecondaryUnder-developed, low-density beans
Insect Damage
SecondaryBeans with insect bore holes
