Post-harvest processing and its effect on flavor
You will discover how harvest timing, processing methods, and fermentation drive the sensory profile of coffea canephora. Post-harvest choices often matter more for flavor than small differences in agronomy.
Harvesting and cherry selection
You will pick ripe, uniform cherries to maximize cup quality; selective picking improves quality but increases labor. Overripe or underripe cherries create off-flavors and fermentation defects.
Processing methods overview
You will learn that three primary processing methods — washed (wet), natural (dry), and semi-washed/honey — produce distinct flavor outcomes. Controlled fermentation and drying are critical to avoid undesirable sourness, mold, or over-fermentation.
| Processing method | Key steps | Typical flavor impact |
|---|---|---|
| Washed (wet) | Pulping, soaking/fermentation, washing, drying | Cleaner cup, brighter acidity, less body |
| Natural (dry) | Drying whole cherries | Fruity, heavy body, increased sweetness, risk of fermentation defects |
| Semi-washed / honey | Pulping with mucilage retained, limited fermentation, drying | Increased body, sweetness, balanced acidity |
Fermentation and microbial management
You will manage fermentation to develop desirable aromatic precursors while avoiding spoilage. Controlled fermentation (timing, temperature, inoculants) can enhance fruity or floral notes, but uncontrolled conditions produce off-odors.
Drying and moisture control
You will dry to target moisture content (usually 10–12%) to prevent mold and quality loss. Even drying with regular turning on raised beds reduces anaerobic pockets and prevents fermentation defects.
Milling, storage, and quality control
You will process parchment and green coffee carefully to preserve quality and reduce defects. Proper storage conditions prevent moisture uptake, pest infestation, and quality deterioration.
Hulling, grading, and defect sorting
You will hull parchment, dry-green coffee properly, and sort to remove defects and unripe beans that cause negative sensory attributes. Visual and density sorting protects cup quality.
Storage best practices
You will store green coffee at stable, low humidity and moderate temperatures to preserve aroma. Packaging in jute or hermetic containers depending on duration and transport conditions helps maintain quality.
Sensory analysis and cupping for quality improvement
You will use cupping protocols to evaluate and monitor your coffee’s sensory profile systematically. Sensory evaluation helps you link field and processing practices to flavor outcomes and guides improvement.

| Positive qualities (specialty) | Sweetness, caramel, cocoa, fruitiness with careful processing |
Roasting and flavor development
You will learn roasting principles that shape the final cup and how to roast canephora to accentuate its strengths. Roasting transforms chemical precursors from the farm and processing stage into volatile compounds you perceive as flavor and aroma.
Roast level choices and sensory effects
You will find that darker roasts reduce perceived acidity and highlight body and caramelized bitterness, while lighter roasts can preserve more nuanced aromatics if the green coffee quality supports it. For many canephora lots, medium-dark roasts produce a balanced, robust cup.
Roast profile considerations
You will control time, temperature ramps, and development time to manage Maillard reactions, caramelization, and aroma formation. Slower development near the end of roast can increase sweetness and complexity, while very fast roasts may enhance bitterness.
| Roast level | Typical sensory outcome |
|---|---|
| Light | Preserves origin character and acidity (rare for Robusta) |
| Medium | Balanced body and acidity; aromatic detail |
| Medium-dark | Emphasizes body, chocolate and caramel notes |
| Dark | Heavy body and smoky or burnt notes; risk hiding origin nuances |
Brewing and serving recommendations
You will adapt brewing techniques to get the best expression from canephora. Methods that highlight body and mouthfeel (espresso, French press) often suit Robusta, but well-processed canephora can be interesting as filter coffee too.
Espresso and blends
You will often see canephora used in espresso blends to increase crema, body, and caffeine. A modest percentage of canephora (10–30%) in specialty blends can add structure without overpowering cup clarity.
Filter and immersion brewing
You will use immersion methods to explore sweetness and body, adjusting grind and brew ratios to manage extraction. Water temperature and grind fineness are key to avoiding over-extraction bitterness.
Blending strategies and value addition
You will consider blending canephora with arabica or other components to balance flavor, increase stability, or create signature profiles. Value addition through roasting, packaging, and storytelling opens higher-value markets.
Specialty potential and single-origin Robusta
