Below Indonesian Coffee Specification :
In Indonesia, green coffee beans are typically graded according to a system that considers the size, weight, and the presence of defects. The grading system may vary slightly depending on the specific region or type of coffee (such as Arabica or Robusta), but generally, the grades include:
1. Grade 1 (Specialty Grade):
• Defects: 0-3 full defects per 300 grams.
• Moisture Content: 9-12%.
• Screen Size: 17/18.
• Cup Quality: No primary defects, high-quality cup profile with distinct flavor attributes.
• Other: Handpicked, uniform beans.
2. Grade 2 (Premium Grade):
• Defects: 4-12 full defects per 300 grams.
• Moisture Content: 9-12%.
• Screen Size: 16/17.
• Cup Quality: Minimal defects, good cup profile with noticeable positive attributes.
• Other: Mostly uniform beans with minor defects.
3. Grade 3 (Exchange Grade):
• Defects: 13-25 full defects per 300 grams.
• Moisture Content: 10-13%.
• Screen Size: 15/16.
• Cup Quality: Some defects in flavor, but generally acceptable for commercial use.
• Other: Moderate uniformity, more noticeable defects.
4. Grade 4 (Standard Grade):
• Defects: 26-45 full defects per 300 grams.
• Moisture Content: 10-13%.
• Screen Size: 14/15.
• Cup Quality: Noticeable defects in flavor, suitable for lower-end commercial use.
• Other: Less uniformity, higher defect count.
5. Grade 5 (Off Grade):
• Defects: More than 45 full defects per 300 grams.
• Moisture Content: 10-14%.
• Screen Size: Varies.
• Cup Quality: Significant defects in flavor, often used for instant coffee or lower-end products.
• Other: Significant variation in size and color, high defect count.
Indonesia’s diverse coffee regions, such as Sumatra, Java, Sulawesi, and Bali, might also have specific classifications or names for their coffee grades based on local standards and practices. For example, Sumatra’s Mandheling coffee and Java’s coffee have unique characteristics and grading standards that reflect their regional terroir and processing methods.
