1. Fundamentals of Factory Management

Factory management in coffee processing focuses on efficient coordination of people, machines, materials, and processes to ensure quality and profitability.
Key fundamentals include:

  • Proper workflow planning (cherry intake → processing → drying → storage)
  • Hygiene and quality control
  • Equipment maintenance
  • Record keeping and traceability
  • Staff supervision and safety Good factory management minimizes losses, improves consistency, and protects coffee quality.

2. Importance of Cupping

Cupping is essential because it:

  • Evaluates coffee quality objectively
  • Identifies defects and flavor attributes
  • Guides pricing and market positioning
  • Helps roasters and buyers make informed decisions
  • Ensures consistency across batches
    Without cupping, quality control in coffee is impossible.

3. Essentials of Sensory Analysis

Essential elements include:

  • Aroma (fragrance and smell)
  • Flavor
  • Acidity
  • Body (mouthfeel)
  • Sweetness
  • Balance
  • Aftertaste
  • Uniformity and cleanliness
    Sensory analysis translates chemical and physical properties of coffee into human perception.

4. Evaluation of Green Beans

Green coffee is evaluated through:

  • Physical grading (size, density, color)
  • Defect count (primary and secondary defects)
  • Moisture content (ideal 10–12%)
  • Smell (fresh, grassy vs moldy or baggy)
  • Cup testing after sample roasting
    This ensures only high-quality beans proceed to roasting.

5. Importance of Fermentation

Fermentation:

  • Breaks down mucilage
  • Enhances flavor complexity
  • Develops acidity and sweetness
  • Removes unwanted compounds
    Controlled fermentation is key to clean, expressive cup profiles.

6. Post-Harvest Processes

Post-harvest processes include:

  • Harvesting (selective picking)
  • Pulping
  • Fermentation
  • Washing
  • Drying
  • Hulling
  • Sorting and grading
    Each stage directly impacts final cup quality and shelf life.

7. Coffee Variety with More Flavor & Best Cup Profile

Arabica coffee has more flavor and superior cup profiles compared to Robusta because:

  • Higher sugar and lipid content
  • More aromatic compounds
  • Lower caffeine (less bitterness)
  • Greater genetic diversity
    Varieties like SL28, SL34, Geisha, and Bourbon are known for exceptional flavor clarity.

8. Two Ways to Make Pour-Over Coffee

  1. V60 Method – Conical dripper with spiral ribs for clarity and acidity
  2. Kalita Wave – Flat-bottom dripper for balanced and even extraction

9. Ristretto vs Espresso (Caffeine Content)

Espresso has more caffeine than Ristretto.
Reason:

  • Espresso uses more water and longer extraction time
  • Ristretto is shorter, more concentrated, but extracts less caffeine

10. Coffee Sustainability

Coffee sustainability means:

  • Environmentally responsible farming
  • Fair wages and livelihoods for farmers
  • Ethical sourcing and trade
  • Climate-smart practices
  • Long-term viability of coffee production
    It balances people, planet, and profit.

11. Circular Economy

A circular economy is a system where:

  • Waste is minimized
  • Resources are reused, recycled, or regenerated
  • By-products (coffee pulp, husks) are converted into value (compost, energy, cascara)
    In coffee, it promotes zero waste and maximum value creation.
