Recommended Action: Processing

From an extension perspective, processing is where value is either created or lost. Even well-grown coffee can be downgraded by poor processing, while disciplined processing can significantly increase price through improved cup quality and consistency. The objective is to ensure clean, controlled, and traceable processing from cherry to dry parchment or green bean.

1. Start with Strict Cherry Selection

• Only process fully ripe, red cherries—never mix with unripe or overripe fruit.

• Enforce sorting at intake:

  • Remove green, black, or damaged cherries

  • Reject contaminated or fermented lots

• Train pickers and buyers to understand that quality begins at harvest, not at the mill. 

Extension Insight: Poor cherry selection cannot be corrected later—this is the single most important control point.

2. Maintain Lot Separation and Traceability

• Keep coffee separated by:

  • Farmer or field

  • Harvest day

  • Variety (if applicable)

• Label and track each lot throughout processing.

Extension Insight: Traceability allows identification of quality problems and enables premium market access (e.g., micro-lots). 

3. Choose the Right Processing Method

• Select processing method based on:

  • Climate conditions

  • Available infrastructure

  • Target market (quality vs volume)

• Main methods:

  • Washed (wet process): Higher quality potential, requires water and control

  • Honey (pulped natural): Balance between quality and resource use

  • Natural (dry process): Lower cost but higher risk of defects 

Extension Insight: The method must match capacity—poorly executed “high-quality” methods produce worse results than well-managed simpler ones.

4. Ensure Proper Pulping and Fermentation Control (Washed Process)

• Pulp cherries quickly after harvest to prevent uncontrolled fermentation.

• Maintain equipment:

  • Properly adjusted pulper discs and knives

  • Clean, well-maintained machinery

• Control fermentation:

  • Monitor time carefully

  • Avoid over- or under-fermentation

Extension Insight: Fermentation is a precision step—small mistakes significantly affect cup profile.

5. Manage Water Use and Cleanliness

• Use clean water at all stages (pulping, washing, soaking).

• Avoid reusing contaminated water.

• Ensure processing areas are:

  • Clean

  • Well-drained

  • Free from contamination sources

Extension Insight: Dirty water introduces defects and off-flavors that cannot be removed later.

6. Drying is a Critical Control Point

• Dry coffee slowly and evenly to safe moisture levels.

• Use appropriate drying methods:

  • Raised beds (preferred for quality)

  • Patios

  • Solar or mechanical dryers 

• Turn coffee regularly to ensure uniform drying.

• Protect from:

  • Rain

  • Excessive heat (which causes case hardening)

Extension Insight: Most quality losses occur during drying—uneven or rushed drying leads to defects and reduced market value.

7. Prevent Contamination During Drying

• Never dry coffee directly on bare soil.

• Keep drying areas:

  • Clean

  • Free from animals, dust, and foreign materials

• Separate different lots during drying.

8. Control Final Moisture and Storage Conditions

• Dry coffee to safe moisture levels before storage.

• Store in:

  • Clean, dry, well-ventilated conditions

  • Appropriate bags (e.g., breathable materials)

• Avoid:

  • Re-wetting

  • Exposure to humidity

Extension Insight: Poor storage reverses all gains made during processing.

9. Train Labor and Standardize Procedures

• Ensure all workers understand:

  • Quality standards

  • Processing steps and timing

• Develop simple, repeatable protocols for:

  • Sorting

  • Pulping

  • Fermentation

  • Drying

Extension Insight: Consistency across batches is key for building buyer trust and accessing premium markets.

10. Reduce Waste and Improve Efficiency

• Minimize losses at:

  • Sorting (avoid discarding good cherries)

  • Pulping (reduce bean damage)

• Utilize by-products (e.g., pulp) for:

  • Composting

  • Soil improvement 

11. Align Processing with Market Strategy

• Understand buyer requirements:

  • Specialty vs commercial markets

• Adjust processing protocols to:

  • Enhance cup quality

  • Maintain consistency across lots

Extension Insight: Processing is not just technical—it is a market-driven activity.

Field-Level Takeaway (Extension Emphasis)

Processing is where farmers either capture or lose value. The key principle is control:
“Control the process, and you control the price.”

Clean, consistent, and well-managed processing transforms good coffee into premium coffee—while poor processing wastes the entire season’s effort.
