The Journey From Farm to Flavor: Why Grading Matters
Have you ever wondered why some coffees cost triple the price of others—and actually taste like it? Behind every top-tier brew lies a rigorous system called specialty coffee grading. It’s not just about looks or branding—it’s about purity, flavor, and precision.
From the lush mountains of Sumatra to small-batch roasters in the U.S., grading helps determine which beans earn the prestigious “specialty” label. And for farmers, roasters, and coffee lovers alike, this grading system shapes everything—from pricing to taste.
Let’s break it down and explore why specialty coffee is truly a cup above the rest.
What Is Specialty Coffee Grading?
Specialty coffee grading is the global standard for evaluating green coffee beans before they’re roasted. It assesses things like:
- Bean defects (primary and secondary)
- Moisture content
- Bean size and uniformity
- Cup quality (through cupping)
High grades mean better taste and higher value in the global market.
Two Main Specialty Coffee Grading Systems
Let’s explore the two most widely recognized systems in specialty coffee grading: the SCA standard and Indonesia’s national grading protocol.
1. SCA (Specialty Coffee Association) Grading Standard
The SCA is a globally respected authority, especially for Arabica beans. It uses a 350g green coffee sample and classifies beans into 5 grades based on defects and cup quality:
SCA Grades Explained:
- Specialty Grade:
- 0 primary defects
- ≤5 secondary defects
- Must have one distinctive attribute (flavor, aroma, acidity, or body)
- 9–13% moisture
- No taints, faults, or Quakers
- Premium Grade:
- Few primary defects, max 8 secondary
- May contain up to 3 Quakers
- Still offers solid cup quality
- Exchange Grade:
- Up to 23 secondary defects
- May have 5 Quakers
- Often found in mass-market coffee
- Below Standard Grade:
- 24–86 defects
- Poor cup quality, usually discounted
- Off Grade:
- Over 86 defects
- Undrinkable, bitter, or sour

2. Indonesian Coffee Grading Standard (SNI)
Indonesia’s unique terrain and processing styles require a tailored system. The SNI (Standar Nasional Indonesia) grading uses a 300g sample to classify beans based on defects, size, and appearance.
SNI Coffee Grades:
- Grade 1: Max 11 defects
- Grade 2: 12–25 defects
- Grade 3: 26–44 defects
- Grade 4a & 4b: 45–80 defects
- Grade 5: 81–150 defects
- Grade 6: 151–225 defects
Beans like Mandheling Grade 1 often exceed global expectations, commanding premium prices in the export market.
Understanding Defects in Specialty Coffee Grading
Coffee defects are critical to grading. They fall into two main categories:
🛑 Primary Defects:
- Full sour or full black beans
- Insect damage
- Mold or fungus
- Fermentation faults
⚠️ Secondary Defects:
- Broken, chipped, or malformed beans
- Slight discoloration
- Shells or parchment fragments
Too many defects? The beans get downgraded—no matter how good they smell.
How Graders Cup and Score Specialty Coffee
Once sorted, beans go through cupping—a sensory evaluation process to score flavor, body, acidity, sweetness, and aroma.
Cupping Criteria Include:
- Cleanliness of flavor
- Balance and complexity
- Uniformity and consistency
- Presence of taints or faults
Beans scoring 80+ on the SCA scale are classified as specialty coffee.

Why Specialty Coffee Grading Matters for You
Grading isn’t just a technical checklist. It ensures:
- Consistent flavor in your daily brew
- Fair pricing for farmers producing high-quality beans
- Better traceability for buyers and roasters
- Long-term sustainability for the global coffee supply chain

How to Choose Beans Based on Their Grade
When buying green or roasted coffee, check the label or ask your roaster:
- Is it Specialty Grade?
- What’s the cupping score?
- How many defects per batch?

Final Sip: What Grade Is in Your Grinder?
Next time you grind your beans, ask yourself—what journey did they take? How were they graded, sorted, and scored? Understanding specialty coffee grading adds depth to your daily ritual. It’s not just coffee. It’s craftsmanship in a cup.
So, what grade will you try next? Will you aim for Specialty Grade or explore Indonesia’s finest?
